What we do
Everything a funded startup needs to reach a real v1.
You have just raised. The clock is running and the next milestone is proof. We compress months of product work into weeks without cutting the corners that matter.
02
Applied AI
Custom models and LLM pipelines that actually ship: retrieval systems, recommendation and pricing engines, and AI features grounded in your real data.
03
Full-stack product
Web, mobile, infrastructure, auth and payments. The whole stack a first version needs, on foundations you can grow on after the prototype lands.
04
Investor-ready
Built to demo, instrument and tell a story. Everything we ship is wired to measure traction and slot into your seed-stage roadmap.
How we work
A small senior team, no hand-offs, one clear path to shipped.
Step 01
Scope
We find the smallest version that proves the thing, and cut everything that does not earn its place in v1.
Step 02
Build
The people you meet write the code and train the models. We build the spine first and put working software in your hands every week.
Step 03
Ship
We deploy real, instrumented product you can demo, measure and grow on. No throwaway, no lock-in.
The team
Founders and an AI researcher who build it themselves.
Seniority and direct founder access is the product. With Merryweather you work with the people writing the code, not a delivery floor.
