A8C Ventures · Build
How we build. How we work with founders. What we’re looking for.
A8C Ventures is a studio. We build vertical AI products and support the founders building them. The full thesis lives at /think. This page is the operating model.
The studio
We come up with the idea, do the work to validate it, find the founding team, set the company up, and support it through the early stages.
The studio’s role is to originate, validate, and operate.
How we run is part of the model. A8C is an AI-native firm — operated by humans, augmented by an agent OS we built and use to do the studio work itself. Leverage comes from the apparatus, not the headcount.
What we build for
Vertical AI for industries where information asymmetry costs people most.
Horizontal AI tools get any given workflow about 30% of the way there. Closing the rest requires knowing how the industry actually runs — the language, the incentives, the workflows incumbents stopped questioning a decade ago. That’s where vertical AI compounds.
We pick industries where three things are true at once:
- The professional class charges high fees for work that’s largely mechanical. Pattern-matching, recall, judgment-on-rails. Real expertise lives at the edges; most of the day is the center.
- The customer absorbs the cost when something goes wrong. Bad outcome, worse alternative, no leverage to switch.
- The right software can make expertise portable — embedded in the product, not the user. The win condition isn’t a better dashboard. It’s a product that knows what an expert would do and does it.
In practice, B2B and B2B-adjacent is where these three criteria converge — that’s where we hunt. Consumer stays on the table when the unit economics make sense; usually, they don’t.
The market that opens when a generation of small operators finally gets access to expert-grade software is enormous — and it won’t be captured by general-purpose AI or by the incumbents whose stacks were built around the operational layer. It’ll be captured one vertical at a time.
What we’re not
- Not a fund.
- No LPs, no outside capital, no obligation to deploy on anyone else’s timeline. Decisions get made on the merits.
- Not an accelerator.
- No cohorts. No demo days. No twelve-week programs. We pick companies carefully and build them slowly.
- Not anti-horizontal-AI.
- Foundation models are the substrate. We build on top of them, not against them. Vertical AI without strong horizontal AI underneath doesn’t work.
What we’ve built
ChangePlate.
Retention intelligence for independent gyms. Forty years of exercise-adherence research, embedded in software priced for a 200-member gym.
10,000+ independent operators. Members worth $1,800–$2,400 a year. Most churn in 90 days. The behavioral signals that predict churn fire three weeks before cancellation — and no gym software was built to see them.
A 15% reduction in monthly churn is a six-figure swing for a typical gym. The window is now.
Who we want to hear from
Founders building in vertical AI.
If you’re shipping something, or thinking about it, we want to talk. The bar is technical depth and the ability to explain complex ideas clearly. If you can build the thing and write about it, send a link.
