A few months ago, Y Combinator issued a call for startups naming a category it has avoided for decades: services businesses. Insurance brokerage. Accounting, tax, and audit. Compliance. Healthcare administration.

There’s a reason venture had traditionally stayed away. Services businesses have always been “body bound.” Add a client, add a person. Revenue and headcount move together, so there’s no operating leverage, and no operating leverage means no venture-scale return. A firm can be great and still cap out at a normal-business multiple.

Here’s what’s actually changed, per Gustaf Alströmer, the YC partner leading this category. A few years ago, if you wanted to build a startup around insurance brokerage, you built software that brokers used to do their job. More recently, you built an AI copilot to help them do it faster. YC’s new bet skips both:

→ Old playbook: build software the professional uses

→ Recent playbook: build an AI copilot that speeds the professional up

→ New playbook: replace the professional, AI does the labor directly

That third version is what makes services fundable. If a team of five can deliver what used to take fifty, revenue can finally grow faster than headcount. That’s the exact return profile venture capital has always required, showing up in a category built entirely on hours.

The categories YC named aren’t random either. Insurance brokerage, accounting, compliance, healthcare admin are all already outsourced. A company doesn’t have to develop a new habit to work with an outside vendor. They already do. The only question becomes who’s doing the work.

That’s the real headline. AI just made a category built entirely on hours look fundable, maybe for the first time in venture history.

If you run a services company and are interested in leveraging AI to achieve product-like software margins, the Legible team and I would love to talk to you.
