How to vet a senior operating advisor before the 100-day plan starts

The deal closes on a Friday. By Monday the board wants a senior operating advisor inside the portfolio company, and the 100-day plan starts whether the right person is there or not. Most sponsors pick from a short list of people they've met at conferences, read a polished bio, and hope. Then day 60 arrives and the plan has a deck, a steering committee, and no owner. Nobody chose badly on purpose. The search optimized for the wrong thing: credentials that read well in a board deck instead of evidence that the person can carry a plan to a result.

Here's what to look for. A senior operating advisor worth the seat has owned an outcome, not advised on one. They've held the chair you're asking them to support. They commit to a first measurable result, and a date for it, before anything gets built. And they leave behind a company that runs without them. Everything else on the bio is decoration.

I've been in this chair nine times. I spent thirty years inside nine PE-backed technology companies, the last twenty running them as President or CEO. The difference between an advisor who helps and one who costs you a quarter shows up in the first two weeks, and you can test for it before you sign anyone.

Start the search with people who have run companies like yours, not people who present well about them. Former CEOs and COOs from your own portfolio, operating partners at other sponsors who've watched them work, and executives your management team has worked beside are better sources than any list. A referral from someone who saw the person under pressure beats a polished introduction every time. Finding names is the easy part. Vetting them is where sponsors get it wrong. Give yourself the time. The pressure to have someone in the building by week one is real, but a two-week delay for the right person costs less than a quarter spent with the wrong one.

The first question is who owned the outcome. Ask for a result they're proud of, then ask who would have answered for it if it missed. Advisors describe what they recommended. Operators describe what they owned, the date it was due, and what they did when it slipped. If every answer is some version of "we helped the team," keep looking.

The second question is what they committed to before anything was built. This is where Commitments Before Scale earns its place in the interview. A serious operating advisor asks for four things before the work starts: an executive owner, an adoption path, a funding rule, and a consequence everyone agrees to in advance if it doesn't land. If a candidate is comfortable starting on a head nod, they'll be comfortable ending on one. A head nod is not a commitment.

The third question is what ran without them afterward. Ask what the company still did six months after they left. The right answer names a weekly cadence, decision rights the leadership team still uses, and a scorecard someone other than the advisor still reads. The wrong answer is a list of deliverables. Heroes don't scale. Systems do.

The fourth question is whether they've held the seat. Advising a CEO and having been one are different jobs. Someone who has held the CEO, COO, or CRO seat knows which problems the board sees first and which ones the team keeps quiet. It's why KeyDelta is built on a Managing Partner and six Principals who, between them, have held the CEO, COO, and CRO seats. You don't need a person who has held all three. You need one who has held the seat you're hiring them to strengthen.

The fifth question is the one most sponsors forget: how do they handle the sponsor channel? A senior operating advisor sits between the board and the portfolio CEO. If they report around the CEO, the CEO stops trusting them and the plan stalls. If they never report up, the board flies blind. Ask how they handled a CEO who was missing the plan. You want someone who tells the CEO first, the board second, and both the same thing. The best senior operating advisors make the CEO the one who carries the good news upward. The plan works when the CEO looks stronger to the board at day 90 than at day one, and that only happens when the advisor stays on the CEO's side of the table while telling the truth to both.

Then watch for the red flags. A deck in the first two weeks instead of a named constraint. A senior partner who sells the work and a junior team that shows up to do it. An hourly clock, which rewards time spent instead of outcomes delivered. A playbook from their last company, applied to yours before anyone has looked at how your company runs. If they know the answer before they've met your leadership team, they're selling the last answer. One more: a candidate who can't tell you about a time a plan went wrong on their watch. Everyone who has carried a real plan has missed something. The ones worth hiring can tell you what they missed, what they changed, and what it cost.

Here's what the first 30 days should prove. Within two weeks, a good operating advisor names the execution constraint, the one thing standing between the plan and the result, and shows you the evidence. By day 30 there's a first measurable result. Not a plan for a result. A result. That's how we run a Diagnostic Sprint: two weeks to find the constraint, a VOOCS diagnostic that scores where execution stalls, and a first measurable result by day 30. If a candidate can't tell you what their first measurable result will be in the first conversation, they won't know it in week four either.

By day 90 the operating model should run through the company's own team. Decision rights are signed by the people who hold them. One weekly cadence closes decisions in the room. The leadership team can name who owns each outcome without looking it up. If the plan still needs the advisor in every meeting at day 90, you didn't hire a system. You hired a hero.

Here's what that looks like when it works. In one KeyDelta engagement, a PE-backed cloud infrastructure company had merged five companies with 1,400 employees across three continents, and the same words meant different things in each. One shared operating language and one cadence turned five entities into one company, and a $180M combined pipeline was reconciled from five conflicting definitions to one. In another, a carve-out plus five acquisitions had left six siloed entities where information was currency. They became one platform with one cadence. In a PE-backed SaaS company, KeyDelta and a revenue operations partner took pipeline accuracy from 68% to 87% in 9 months. And in a prior operator-CEO role, before KeyDelta, the same sequence took a PE-backed digital publishing platform from $30M to $100M in revenue over the hold, to a strategic exit.

Every one of those started with the operating model, not the deck. That's the test to put every candidate through. The advisor you want won't win the first board meeting with slides. They'll make the CEO more effective by week four and less dependent on them by week twelve. Put the answers in writing before anyone starts: the outcome they own, the first measurable result and its date, the executive owner on your side, and how the engagement ends. An advisor who balks at writing that down has told you what you need to know.

So before the 100-day plan starts, ask three things. Who owned the outcome? What did you commit to before anything was built? What ran without you afterward? The candidates who answer those cleanly are the ones worth the seat. Define it. Measure it. Own it. Close it. Scale it.
