Bench strength and succession

Use this skill when a CEO, CRO, sales leader, board, or PE operating partner needs to know whether the team could survive the loss of a key person, who is ready to step up, and what to do about the gaps. Produces a critical-role bench scorecard with single points of failure, an evidence-based performance and potential map, readiness calls for every successor, emergency coverage plans, and a talent review run with bias controls. Use it for "bench strength", "succession plan", "talent review", "9-box", "who replaces our VP Sales", "key-person risk", "are we too dependent on one rep", "high-potential list", or "board wants a succession plan".

Board meeting prep

Use this skill when a CEO, CRO, or GTM leader is preparing for a board meeting, investor meeting, or operating review and needs the room to decide something. Produces a decision-first pre-read, an in-room agenda budgeted for discussion, a single primary ask framed as a decision brief, and a Q&A and director preparation brief. Use it for "board deck", "board prep", "board pre-read", "what should I ask the board for", "presenting GTM to the board", "investment case for the board", "first board meeting as a new CRO", or "the board keeps asking why we are not growing faster".

Hiring scorecard

Use this skill when a founder, CEO, CRO, or hiring manager is making a hire where a miss would cost more than three times the salary: a first sales leader, CRO, CMO, co-founder, first-of-role hire, fractional executive, or key manager. Produces an outcome-based scorecard, a behavioral interview kit, a reference-check plan, and a decision package with a logged, reversibility- framed decision. Use it for "hiring scorecard", "interview kit", "should we hire this candidate", "evaluate a VP Sales candidate", "first sales hire", "co-founder evaluation", "two finalists, help me decide", or "our last sales leader did not work out".

Investor update

Use this skill when a founder, CEO, or CRO is writing to investors, board members, advisors, or prospective investors between meetings: a monthly or quarterly investor update, a pre-board narrative, a bad-news note, a fundraise progress update, or a diligence answer. Produces an update that leads with one headline, reports a consistent metrics frame, names wins, risks, and specific asks, and passes an honesty check before it ships. Use it for "investor update", "monthly update to investors", "board update", "advisor email", "update for prospective investors", "how do I tell investors about a miss", "answer this diligence question", or "nobody replies to my updates".

Leadership development diagnostic

Use this skill when a CEO, CRO, sales leader, board, or investor needs an honest, evidence-based read on a leader and a plan that changes behavior. It checks the system before the person, measures where the leader's time actually goes against their stage, combines 360, direct observation, and a live practice test, delivers the diagnostic in a way the leader can hear, and ends in a readiness verdict and a 90-day sprint. Use it for "leadership assessment", "360 review", "development plan for my VP", "I am the bottleneck", "new manager struggling", "promoted to manager of managers", "is this leader ready for the next stage", or "should we promote, develop, or replace this leader".
