Turn your idea into a real product in weeks, not months.

We design, build and launch MVPs for founders who need to validate fast. No bureaucracy, no bloated agency, no half-finished prototype.

AI speeds things up. An experienced dev steers. AI without someone who knows what they're doing creates the illusion of progress. Then technical debt stalls the product in 3 months.

Why work this way

Most software dies before it finds a user.

We build for founders who would rather learn from 100 real users than polish a deck. Lean, opinionated, shippable. That's how an MVP should work.

01

Validate before you build

Test your idea with real users before spending 6 months and $100k on a guess. Get fast feedback, kill wrong assumptions early.

-68%
less time spent on the wrong feature
02

Ship the smallest thing that works

We cut your idea down to the essentials. One value proposition, done well, in production. The rest waits for the next sprint.

4 to 8 wks
from kickoff to a live MVP
03

You own the code, the brand, the data

No vendor lock-in. Clean repo, clean handoff. You walk away with a real product to extend, refactor or sell.

100%
yours from day one
04

AI in the process, a dev in command

We use AI to speed up discovery, design and build, always reviewed by someone who understands architecture, security and product. AI without technical experience writes code that looks right and breaks in production.

The process

Eight weeks. Four checkpoints. Zero theater.

Same rhythm on every project. You always know what comes next week, what goes live on Friday and where the budget is going.

Week 1
1

Shape the idea

Two days with you. We map the user, the positioning and the riskiest assumption. You leave with a one-page brief everyone signs off on.

Week 2
2

Design the prototype

Wireframes → Figma prototype. We test with 5 real users before writing a line of code. Cheap to throw away, expensive to skip.

Weeks 3 to 6
3

Build, ship, repeat

Daily Slack, weekly demo, a staging deploy every Friday. By week 4 your product is in production with real signups.

Weeks 7 to 8
4

Hand off or keep going

Clean codebase, complete docs, a 1h handoff call. Or we stay on retainer and keep iterating. Your call, no strings.

From the founder

"I started this because every great product I've ever launched began as something small and seemingly simple."

For twelve years I've been the engineer who is always starting new projects and shipping them to market. Founders call me when they really need to validate a product faster, without throwing code away afterwards.

We don't sell hours. We sell a working product, on a date that fits your calendar.

FAQ

Honest answers to the questions founders actually ask.

Most projects land between $4k and $55k. Price is set by scope (how many flows) and integrations, not by hours. We send a fixed proposal after the first call. No surprises, no hidden hours.
