We let fractional CFOs bid on warm introductions. Here's what the first numbers say.

Infinia · 2026-10-19

Every growing company hits the same moment. It needs a CFO or a CTO before it can afford one. On paper, fractional leadership solves this: you get a senior operator for ten hours a week instead of paying a $400K salary.

In practice, the market is broken in a specific way. It isn't short of supply. It has lost its signal.

The problem: everyone is fractional now

Open LinkedIn and count the "Fractional CFO" titles. The number of US profiles with "fractional" in the job title has more than tripled since 2019 (Lightcast). Some of those people have scaled three companies. Some had a title change last quarter. From the buyer's side, the profiles look identical.

So founders fall back on the only filter they trust, which is their network. That works if your network happens to include a great fractional CFO. If it doesn't, you hire late, or you hire whoever replied first.

The other side is just as stuck. 94% of fractional executives say they've won clients through referrals (Fractional Work Report 2026). That's a nice way of saying the channel they depend on is unpredictable. The best operators spend unbilled hours chasing buyers who turn out not to be ready.

That leaves two groups who badly want to find each other, with no trustworthy way to do it.

What we built: a Dutch auction for introductions

Infinia does one thing. It produces a warm introduction between a pre-vetted buyer and a matched fractional executive. How that introduction gets priced is the part people ask us about.

1. The buyer is vetted first. We confirm need, stage and budget before anyone sees the opportunity.
2. Only matched executives can see it. Fit gates who can bid. Money doesn't.
3. The price starts high and drops. The first matched executive to accept wins the introduction. It's exclusive, so nobody else gets that buyer.

We chose a descending auction over a fixed rate card for three reasons:

• Price discovery. We don't know what a warm intro to a Series A company that needs a CFO is worth. The market does.
• Exclusivity. One winner per buyer means the executive shows up committed rather than as one of five cold pitches.
• The executive pays before the intro. This solves the problem that kills most services marketplaces, where the two parties meet and then route around the platform. We've already been paid, so a direct relationship afterward is the point, not a leak.

The first numbers

As of October 18, 2026, across [N] introductions:

Two of these surprised us.

The 2-minute claim time. In a descending auction, a fast claim means the price barely had time to fall. Twelve qualified executives are racing for something that's priced too low. The executive's average return is about 212× what they paid. We're leaving money on the table, and that's the best problem a marketplace can have.

Buyer acquisition costs more than one intro earns. It costs us about $200 to bring in a vetted buyer, and one intro clears at $139. The model works because buyers come back for a second role and a second hire.

Why this matters more in an AI world

AI is shrinking teams. It isn't shrinking the need for judgment. A company that once hired a finance team of five may run on two people and a stack of agents. It still needs someone who has closed a Series B or survived an audit. That person increasingly works for several companies at once.

We think leadership is becoming on-demand by default, and that the hard problem in that world is trust. Who has actually done the job, at your stage, recently?

Introductions are our wedge. The roadmap goes like this:

• Now: match buyers and executives through exclusive, market-priced intros.
• Next: run the engagement itself, with contracts, billing and outcome tracking. Every engagement adds to a record of who delivered what.
• Then: package fractional leaders with AI execution and sell outcomes ("close the books monthly") instead of hours.

The record from the middle step is what nobody else has. A LinkedIn title says someone is a fractional CFO. A delivery record says they did it, at what stage, and how it went.

What we're still figuring out

• How to raise starting prices without slowing claims.
• How to keep a highest-bidder dynamic from ever outranking fit. Today fit gates the auction, and we want to keep it that way.
• How to grow the buyer side efficiently, because in a marketplace demand is the game.

If you have opinions on any of these, especially if you've built or run a marketplace, we'd genuinely like to hear them.
