1729 AI Labs

For founders and CEOs

Find product-market fit in more loops, not more months.

PMF is a search. Every iteration is a guess tested against real customers. Most startups get four or five a year, because each one costs a hire and a quarter. With 1729 you get one a week — the whole product, live, in your repo — so you run more of the loop before the money runs out.

You don't find PMF by building. You find it by finding out.

01

The loop is the bottleneck

It's not your team. It's how long each guess takes to test.

You raised money to learn what customers want. Most of it goes to waiting — for the hire, for the sprint, for the next quarter. So you ship a slice, wait for usage, and learn about the slice. Eighteen months of runway is six turns of that loop. Six guesses to find fit.

Guess → "Do we have capacity?" → Roadmap fight → Sprint → Ship a slice → Wait for usage → Learn in Q3

Faster coding tools made your three engineers faster. The loop is still a quarter.

02

What changes

Build the whole thing. Learn from the whole thing.

Not the MVP of the MVP — the product you pitched. Your guess becomes a clickable product on day one, customers react the same afternoon, and the version they approve is in production in weeks. Then you change it and the next guess starts the same day.

The only limit is how fast you can decide.

Day 1

Your pitch becomes a product

Every screen, every role, clickable. Put it in front of customers the same afternoon.

Week 1

Their reaction is in. Second version out.

Four versions before you commit a line of backend. What they approve is what gets built.

Weeks 2–6

Built to production, in your repo

Real usage, not a demo. The Factory builds what they approved while your team sells.

Then

Change it. It ships again.

Hit update. The next guess starts the same day, not next quarter.

03

8 weeks

Today, a full product ships in under a month.

Every feature. All at once.

05

Ownership

It's your code. It's your company.

Standard stack, in your repo, on your cloud. Your next hire can read it. Your team can extend it. No proprietary dependency to unwind and no handover standing between you and the company you are building.

And it's your learning: the decision record shows what customers rejected and why.

We carry the build. You keep control.

  • Your repo
  • Your cloud
  • Your stack
  • Your IP
  • Your decision record
06

Not an agency

This is not a dev shop.

No brief-and-wait. No change-request invoices. No handover your team can't run. You see the product working before anything gets built, you change it yourself after it's live, and your engineers stay on the problems only they can solve. You keep the edge. We carry the load.

The agency

Brief → Quote → Wait → Change requests → Handover you can't maintain

1729

See it → Decide → Built → Yours → Change it → Ships again

07

One working session

Bring us the guess you most need to test.

One working session — you and whoever you'd trust to say no. You see it working, clickable, in front of you, before you decide anything.

If you say go

It's live, in your repo, in under a month.

Your team reviews it. You ship it. Your customers are using it — and telling you what's next — before the next board meeting.

If you don't

You leave with the guess finally clear.

  • What it must do.
  • What can wait.
  • What would make it worth building.

That's a loop turned, for free.

Before we start, we agree what "live" means What ships, by when, and how little your team needs to carry.

Your customers are waiting to tell you what they want. Stop making them wait a quarter.

Your guess. Their reaction. One week.
