Plek AI launches on YC with workforce plans for private equity firms

Private equity firms buy companies, run them for a few years, then sell them for more than they paid. One of the first jobs after a buyout is to look at the workforce. Who does what. Where are the duplicates. Which teams are too deep. Where would a cut or a merger lift profit the most. That work is usually bought from a consulting firm. It takes six to eight weeks, by Plek AI's own account on its launch page. The page says the fee can reach seven figures.

Plek AI, which launched on Y Combinator's Fall 2026 batch, says it does that work in under a minute. The product reads a census of the company's employees and returns a plan. The plan shows where profit can be lifted, lever by lever. The launch page carries nine votes.

Who is behind it

The founders are Pierre Bouquet as CEO and Melchior Carrier as CTO. Plek says it is onboarding with a leading PE advisory firm. The page also says Plek is deployed at a two billion dollar PE fund. Neither is named. Plek also lists Y Combinator, Bain, MIT, Harvard and EPFL as trusted users on the company's own site.

What the product actually does

The company's own site breaks the work into six levers. Spans and layers, which is the shape of the management tree. Senior-level benchmarking. Geographic footprint. Compensation. Exposure to AI automation. And duplicate functions. The input is the employee census, and the output is a plan per lever.

Plek says its model works with 50,000 job roles and 250,000 task categories. A normal consulting study uses about 20 job families, by the company's account. The scale is where Plek pitches its edge against human consultants.

The numbers on the launch page

Plek says it has run four pilots at companies with 13,000, 3,600, 1,000 and 250 employees. At the 3,600-person pilot, Plek says it found 30 million dollars in annual EBITDA levers. EBITDA is a measure of profit. The company says this matched the figure a global PE advisory firm reached in six weeks of work.

Plek describes itself on the launch page as 10,000 times faster than consulting and 12,500 times more granular. Both are the company's own framings. The 10,000 figure compares minutes to six to eight weeks. The 12,500 figure compares 250,000 task categories to about 20 job family buckets. No third-party review of either figure is on the page.

Who should read this

The reader here is a founder, a PE operating partner, or anyone who sells services to them. Plek's pitch is a consulting workflow turned into software. The human is still in the loop at the end. A plan the AI wrote has to be read by the partner and sold to the portfolio company's board. A workforce plan is good or bad once the business tries to reach it. A benchmark cannot settle that. The real question for a buyer is whether Plek's draft is good enough to argue with on day one.
