1. The Hundred-Day Plan That Forgot to Ask Who Was Going to Execute It

The operating partner had done this before — or thought she had. The portco was a $95M B2B services company with a clear expansion thesis: add three verticals, build a dedicated enterprise team, and double marketing-sourced pipeline within 18 months. The hundred-day plan was a work of art. New pricing architecture. CRM migration. Territory redesign. Demand generation budget tripled. Sales process documented and rolled out. Every initiative had a timeline, a KPI, and a budget.

By day 120, the plan was in triage. The VP of Sales — who had nodded enthusiastically through every planning session — turned out to have never managed more than seven reps; the plan called for scaling to 30. The two "enterprise reps" hired in month one had been found through the VP's network, interviewed casually, and joined without any structured assessment of their ability to sell six-figure deals. The marketing leader was a brilliant content creator who had never run demand generation at scale. And the three best reps — the ones who consistently hit number — were actively interviewing with competitors because nobody had identified them as critical retention risks.

The plan was right. The people were wrong. And the operating team did not have a systematic method for knowing the difference.

Two providers approach this problem from fundamentally different directions. Topgrading provides the most recognized talent evaluation methodology in the PE world — a structured system for identifying A, B, and C players and upgrading the talent base systematically. SBI Growth Advisory embeds talent assessment within a broader commercial effectiveness framework, evaluating talent as one dimension of a holistic GTM transformation. One starts with people and works outward to the plan. The other starts with the plan and works inward to the people.

2. TL;DR Comparison Table

3. Why This Comparison Matters

PE operating teams face a fundamental chicken-and-egg problem with commercial talent. The value creation plan defines what the team needs to accomplish. But the team's capability determines what the plan can realistically accomplish. If you build the plan first and evaluate talent second, you risk discovering — at day 90, not day 1 — that the plan assumes capabilities the team does not have. If you evaluate talent first and build the plan second, you risk designing a plan around current limitations rather than the value creation opportunity.

The best approach integrates both: assess the talent against the plan, and adjust both the talent map and the plan based on what the assessment reveals. But the two providers in this comparison emphasize different sides of that integration.

Topgrading approaches the problem as a talent system. The methodology provides a comprehensive, repeatable framework for evaluating every leader and key contributor, segmenting them into A/B/C categories, upgrading the talent base through disciplined hiring, and sustaining talent quality over the hold period. The implicit assumption is that getting the right people in the right seats is the primary lever — get that right, and the plan will be executed.

SBI Growth Advisory approaches the problem as a commercial effectiveness question. Talent assessment is embedded within a broader evaluation of the GTM function — market positioning, sales process, pipeline architecture, pricing strategy, and organizational design. Talent is evaluated not against generic competency models but against the specific commercial strategy the value creation plan requires. The implicit assumption is that talent assessment without commercial context produces information that is accurate but not actionable — you need to know what "good" looks like for this specific company at this specific stage before you can evaluate who is good.

Both assumptions have merit. The comparison matters because the choice between them reflects a fundamental question about how your operating team thinks about value creation: people-first or plan-first.

4. Company Profiles

4a. Topgrading

Positioning & Approach

Topgrading is a talent management methodology developed by Brad Smart and refined over four decades of application across Fortune 500 companies and PE portfolio companies. The methodology's core thesis is that the single most important factor in organizational performance is the quality of talent in key positions — and that most organizations tolerate far too many B and C players because they lack a systematic method for evaluating, upgrading, and sustaining talent quality.

The Topgrading system rests on several interconnected components. The Job Scorecard defines success in the role — not a job description listing responsibilities, but a document specifying measurable outcomes, required competencies, and cultural fit criteria. The Topgrading Interview is a structured, chronological behavioral interview that walks through the candidate's or incumbent's entire career history, exploring successes, failures, key decisions, management style, and self-awareness at each stage. The TORC (Threat of Reference Check) technique embeds accountability into the interview by informing the interviewee that reference checks will be conducted with bosses they identify — creating incentive for honest self-reporting. The A/B/C grading framework provides a clear vocabulary for segmentation: A-players are the top 10% of available talent for the role at the compensation level offered; B-players are the next 25%; C-players fall below the 65th percentile.

PE Adoption & Integration

Topgrading's A/B/C vocabulary has become the de facto standard for talent discussion among PE operating partners — even operating teams that have never engaged Topgrading directly use the A/B/C framework in their talent discussions, board meetings, and value creation planning sessions. This organic adoption reflects the methodology's intuitive alignment with how PE firms think: identify the best, develop the middle, replace the bottom, do it fast.

The methodology is increasingly applied in the PE context for both incumbent assessment and upgrade hiring. Published case studies describe organizations that improved their hiring success rate from 25% to 90%+ by implementing Topgrading's structured interview and reference-check methodology. For PE portfolio companies that need to upgrade 5-10 key commercial positions within the first year of ownership, the difference between a 25% and 90% hiring success rate is the difference between a value creation plan that compounds and one that stalls.

Scalability & Implementation

One of Topgrading's distinctive advantages is that the methodology can be transferred to internal teams. Unlike assessment firms that require ongoing consultant engagement for each evaluation, Topgrading can be taught — operating partners, portfolio company HR leaders, and hiring managers can be trained in the Topgrading Interview methodology and Job Scorecard design, creating an internal capability that persists beyond the initial engagement. This is particularly valuable in PE, where the goal is to build sustainable capability within the portfolio company, not to create dependency on external advisors.

4b. SBI Growth Advisory

Positioning & Approach

SBI Growth Advisory is a commercial effectiveness advisory firm with a dedicated PE practice. The firm's talent assessment capability exists within a broader Revenue Growth Methodology that evaluates every dimension of the GTM function: market strategy, go-to-market model design, sales process and methodology, pipeline architecture, pricing optimization, sales force sizing and deployment, sales management effectiveness, and talent assessment. This integration is deliberate — SBI argues that evaluating talent in isolation, without understanding the commercial strategy the talent is supposed to execute, produces assessments that are accurate in abstraction but not actionable in context.

SBI's talent assessment methodology combines structured interviews with performance data analysis, pipeline behavioral data, and benchmarking against the firm's experience base of hundreds of commercial engagements. The assessment evaluates commercial leaders and teams against the specific requirements of the growth plan: not "is this a good VP of Sales in general?" but "can this VP of Sales execute the enterprise expansion strategy that the deal thesis requires?" This contextual anchoring is SBI's primary differentiation in talent assessment — the evaluation is always relative to the plan, never generic.

PE Ecosystem & Talent Work

SBI's PE practice positions talent assessment as one component of a structured value creation engagement. Published content covers topics like "building the right commercial team for PE portfolio companies" and "assessing sales force capability as part of GTM diligence" — framing talent evaluation as a workstream that feeds directly into operating plan design. The firm's consultants bring pattern recognition from hundreds of commercial engagements, which enables a form of calibrated benchmarking: they can assess a VP of Sales not against a psychometric norm but against the population of VPs they have worked with in similar-stage, similar-complexity commercial organizations.

SBI's engagement model typically runs 3-6 months for a comprehensive commercial transformation that includes talent assessment as a phase. The assessment phase — usually 3-4 weeks — produces a talent map, A/B/C segmentation, and recommendations that are then incorporated into the broader GTM transformation plan. This means the talent findings are not delivered as a standalone report but as an integrated input to an execution plan that SBI itself will help implement.

Post-Assessment Execution

SBI's post-assessment capability is a significant differentiator. The firm does not just identify talent gaps — it helps close them through sales effectiveness programs, coaching frameworks, management development, and organizational design changes that create the conditions for improved performance. This continuity from assessment to action eliminates the handoff problem that plagues standalone assessment engagements, where the assessment firm delivers findings and the operating team is left to figure out what to do with them.

5. Methodology Deep-Dive

5a. How Topgrading Evaluates Commercial Talent

The Topgrading Interview

The Topgrading Interview is a 2-4 hour structured interview that covers the interviewee's entire career chronologically. For each role, the interviewer explores: what were you hired to do? What did you accomplish? What were your key relationships (boss, peers, direct reports)? What were your biggest successes and failures? What would your boss at the time say about your performance? Why did you leave? The depth and chronological structure are designed to reveal patterns that shorter interviews miss — a leader's tendencies around delegation, conflict, team-building, and accountability emerge from the narrative arc of their career, not from a single-role snapshot.

For commercial leaders, the interview surfaces specific evidence about sales team building, quota attainment history, management style, coaching capability, and the ability to hire effectively. A VP of Sales who has built three successful sales organizations and can narrate the specific decisions, mistakes, and course-corrections from each is a fundamentally different profile from a VP who held sales leadership titles but whose teams were inherited, not built.

A/B/C Segmentation

Topgrading's grading framework produces a clear segmentation: A-players in the top 10%, B-players in the next 25%, C-players below the 65th percentile. The grading is relative to the role and compensation level — an A-player for a $150K enterprise AE role is different from an A-player for an $80K mid-market AE role. This role-specificity prevents the common error of grading people against the wrong standard.

The segmentation feeds directly into action planning: A-players are retained and rewarded (and potentially promoted). B-players are developed with specific, time-bound development plans. C-players are managed out on a defined timeline — typically 30-90 days — with replacement hiring conducted using the Topgrading methodology to ensure the upgrade sticks. The action framework is prescriptive, which is both a strength (it drives rapid execution) and a limitation (it may not account for contextual factors that a more nuanced assessment would surface).

Hiring Upgrade Methodology

Topgrading's hiring methodology — Job Scorecard, Topgrading Interview, TORC reference checks — is designed to ensure that replacement hires are A-players, not lateral moves or, worse, downgrades disguised as upgrades. The published claim that Topgrading increases hiring success rates from 25% to 90%+ is based on the methodology's structured approach replacing the unstructured "gut feel" hiring that produces most hiring failures. For PE portfolio companies that need to replace 3-5 C-players within the first 100 days, the quality of replacement hiring is as important as the accuracy of the initial assessment.

5b. How SBI Growth Advisory Evaluates Commercial Talent

Contextual Assessment Framework

SBI's talent assessment begins with the growth plan, not with the people. The assessment team first develops a clear understanding of the commercial strategy — what markets, what segments, what sales motion, what pipeline architecture, what pricing model — and then defines the talent requirements that strategy demands. This produces a "role-specific success profile" that functions similarly to Topgrading's Job Scorecard but is derived from the specific commercial challenge rather than from a generic role definition.

Against this success profile, SBI evaluates incumbents through a combination of structured interviews, performance data analysis, and behavioral observation. The interviews are shorter than Topgrading's (typically 60-90 minutes rather than 2-4 hours) but are focused specifically on commercial capability: how the person thinks about pipeline, pricing, territory management, coaching, and revenue forecasting. Performance data — quota attainment, pipeline metrics, CRM behavioral data — provides quantitative validation of interview findings.

Talent Map & Gap Analysis

SBI's talent evaluation produces a talent map that segments the commercial organization using an A/B/C framework — though the firm's vocabulary is not always identical to Topgrading's. The key difference is that the segmentation is anchored to the growth plan's requirements, not to a generic competency standard. A rep who is a solid performer in the current mid-market motion might be rated as a C for the enterprise expansion the plan requires — not because they are incompetent, but because the plan demands skills they do not have and cannot develop fast enough.

The gap analysis extends beyond individual ratings to organizational capability: Does the sales management layer have the coaching infrastructure to develop B-players? Is the hiring process capable of attracting A-level talent at the compensation range the plan budgets? Does the sales enablement function provide the training and content that new hires need to ramp effectively? These organizational capability gaps are as important as individual talent gaps — and they are where SBI's broader commercial advisory capability adds unique value.

Integration with GTM Transformation

SBI's talent findings do not get delivered as a standalone report. They are incorporated into a comprehensive GTM transformation plan that addresses talent gaps alongside process gaps, tooling gaps, and strategy gaps. This integration ensures that talent actions are coordinated with other commercial initiatives — a rep development program is designed around the new sales methodology being implemented, not around a generic competency model. A replacement hiring profile is built around the specific territory and segment strategy being deployed, not around an abstract ideal.

6. Pricing & Engagement Economics

The pricing comparison is structurally asymmetric because the engagements are structurally different. Topgrading can be engaged as a standalone talent assessment and methodology implementation — the firm assesses the team, trains internal leaders on the Topgrading methodology, and exits. The cost is primarily upfront, with minimal ongoing expense because the methodology is now an internal capability. SBI's talent assessment is embedded within a comprehensive commercial transformation that costs 3-5x more — but includes strategy, process design, sales effectiveness, pricing, and organizational design work that Topgrading does not provide.

For PE operating teams that have the commercial expertise to design and execute the GTM transformation plan themselves and need only the talent assessment, Topgrading delivers the evaluation at a lower cost with the added benefit of methodology transfer. For PE operating teams that need a partner for the full transformation — talent assessment plus everything else — SBI's bundled model is more efficient than engaging a talent assessment provider and a separate commercial advisory firm.

7. Deal Fit Matrix

Best fit for Topgrading:

• You want a talent evaluation system, not a one-time assessment. The portco needs an ongoing capability for evaluating incumbent talent, grading new hires, and systematically upgrading the organization over the hold period. Topgrading's methodology can be implemented as a permanent operating system — trained into the HR team, the hiring managers, and the executive leadership — so that every hire and every promotion is evaluated with the same rigor. This compounds over a 4-5 year hold.

• The operating team has strong commercial strategy capability but lacks a structured talent evaluation method. The operating partner knows what the GTM plan should be. They know what roles need to exist and what outcomes those roles need to deliver. What they lack is a systematic, bias-resistant way to evaluate whether the current people can deliver and whether the replacement hires will be upgrades. Topgrading provides the method.

• You need to evaluate leadership across functions, not just sales. The portco's talent risk is not limited to the commercial organization — the CFO, the CTO, and the head of operations all need evaluation. Topgrading's methodology is function-agnostic, which makes it efficient for a full leadership assessment that includes the commercial team.

Best fit for SBI Growth Advisory:

• The talent assessment needs to be integrated with a broader commercial transformation. The portco does not just have a talent problem — it has a strategy problem, a process problem, a pricing problem, and a tooling problem. Assessing talent in isolation will identify the wrong people, but fixing the wrong people without fixing the wrong process and wrong pricing will not deliver the thesis. SBI's integrated model addresses all of it in one engagement.

• The operating team needs help defining what "good" looks like for the commercial roles. The growth plan calls for an enterprise sales expansion, but nobody on the operating team has built an enterprise sales organization before. They do not know what an A-player enterprise VP of Sales looks like, what the right sales process is, or how to evaluate whether the current team can make the transition. SBI's pattern recognition — from hundreds of commercial transformations — fills this gap.

• You want talent assessment anchored to revenue outcomes, not generic competency. SBI evaluates talent against the specific revenue targets and commercial motions the plan requires, producing assessments that translate directly into operating plan adjustments: "this team can deliver $12M of the $18M new ARR target; the $6M gap requires 4 new enterprise reps and a VP upgrade."

Other firms to consider:

• For validated sales-specific assessment instruments: OMG's 21-competency sales assessment provides psychometric depth at the individual rep level that neither Topgrading nor SBI offers.

• For executive leadership assessment with psychometric rigor: ghSMART or Korn Ferry provide deeper executive assessment methodology for the CRO/C-suite layer.

• For assessment integrated with hands-on commercial building: Cortado Group combines A/B/C talent segmentation with in-house GTM execution — building the CRM, pipeline architecture, and sales process alongside the talent evaluation.

8. Head-to-Head Scoring Matrix

Scoring notes:

SBI's scoring advantage is driven by two factors: sales-specific depth (4.5 vs 3.0 — SBI evaluates commercial capability in the context of revenue strategy, while Topgrading evaluates general leadership and management capability) and post-assessment execution (5.0 vs 3.0 — SBI's advisory team can implement the transformation plan that assessment findings require, while Topgrading delivers the assessment and methodology but not the GTM execution).

Topgrading's advantages are A/B/C segmentation methodology (5.0 vs 4.0 — Topgrading literally wrote the framework that the entire industry uses) and methodology transferability (5.0 vs 2.5 — the ability to train internal teams on Topgrading's system creates lasting capability that does not depend on ongoing consultant engagement). For PE firms that value building internal capability over buying external services, this transferability is a meaningful differentiator.

The scores reflect the structural difference between a methodology and an advisory firm. Topgrading provides the system; SBI provides the service. Both are valid approaches — the right choice depends on what the operating team already has in place.

9. Real-World Deal Scenarios

Scenario 1: "The Multi-Portco Operating Partner Who Needs a Repeatable Talent System"

You are the operating partner for a mid-market PE fund with nine portfolio companies. Every board meeting, every hundred-day plan, and every quarterly review involves some version of the same conversation: who are the A-players, who are the B-players, who needs to go. But each portco addresses this question differently — one used a DiSC assessment, another hired a local executive coach who did interviews, a third just relied on the CEO's judgment. You need a single, consistent methodology that every portco can implement, that you can use to compare talent quality across the portfolio, and that creates lasting capability without requiring you to hire a consulting firm for each assessment.

Best fit: Topgrading. This is a system implementation problem. The operating partner needs a methodology that can be deployed across nine companies, produces comparable output (A/B/C ratings calibrated against consistent standards), and becomes an internal capability that each portco sustains independently. Topgrading's training model — teach the methodology to HR leaders, hiring managers, and executives — creates exactly this. Once implemented, each portco has the Topgrading Interview protocol, the Job Scorecard framework, and the TORC reference check process as permanent tools. The operating partner can speak A/B/C across all nine board meetings knowing the vocabulary means the same thing everywhere.

Scenario 2: "The SaaS Portco That Missed Q3 and Nobody Knows Why"

The portco is 18 months into the hold period. The original value creation plan is stalled: Q3 revenue came in 22% below forecast, pipeline coverage has dropped from 3.2x to 1.6x, and the VP of Sales blames marketing for insufficient lead flow while the VP of Marketing blames sales for not following up on the leads that do exist. The operating partner is not sure whether this is a people problem, a process problem, or a market problem — and the answer to that question determines everything that happens next. If it is a people problem, the talent needs to be assessed and upgraded. If it is a process problem, the sales methodology and pipeline architecture need to be redesigned. If it is a market problem, the entire GTM strategy needs to be revisited.

Best fit: SBI Growth Advisory. This is a diagnostic problem that spans people, process, and strategy — and it requires a provider that can evaluate all three simultaneously. SBI's integrated commercial assessment will examine the market opportunity (is the addressable market still real?), the sales process and pipeline architecture (is the commercial engine designed correctly?), and the talent (do the people have the capability to execute?). The talent assessment will be anchored to whatever the commercial diagnostic reveals: if the process is sound and the market is real, the problem is people. If the process is broken, the people may be better than they appear — they are just operating in a system that prevents them from performing. This contextual diagnosis is what prevents the operating team from making the expensive error of replacing people when the problem is the system they are working in.

10. The Intangibles

Vocabulary and adoption. Topgrading has won the vocabulary war. When a PE operating partner says "we need to get A-players in the key seats," they are using Topgrading's language whether they know it or not. This organic adoption means that Topgrading's framework arrives pre-credentialed in most PE environments — it does not need to be explained or justified. SBI's talent assessment is equally rigorous but arrives inside a broader advisory engagement, which means the talent findings are one section of a larger deliverable rather than the headline. For operating teams that want talent to be the central conversation, Topgrading's standalone focus is an advantage.

System versus service. Topgrading's most underappreciated value is that it creates an asset — a talent evaluation capability — that persists after the engagement ends. The methodology, once learned, belongs to the organization permanently. Every hire, every promotion, every performance review can be informed by Topgrading principles without paying a consulting fee. SBI delivers superior advisory value during the engagement, but the capability walks out the door when SBI does (unless the portco's leaders have internalized the commercial strategy thinking, which is harder to transfer than a structured interview protocol).

The "right people in the wrong system" risk. The most important question in GTM talent assessment is whether poor performance reflects poor talent or a poor system. A strong rep in a broken sales process will underperform. A weak manager with a great team will coast on their team's capability. Topgrading's methodology is optimized for evaluating the person — their track record, their capabilities, their potential. SBI's methodology is optimized for evaluating the person in context — the same person might be an A-player in a well-structured GTM function and a C-player in a dysfunctional one. Neither perspective is wrong; the best assessment combines both.
