Rebuilding a payments platform without switching it off
We split a legacy monolith into services while it kept processing live payments, using AI-assisted test generation to cover the old code before touching it.
Your product.
Your stack.
Our squad.
An AI-native product studio. We design, build and run software for growth-stage companies, with AI coding agents in every workflow and LLM features in more and more of what we ship.
Everything a product needs, under one roof.
- PE
Product engineering
Web and mobile products in TypeScript, Python, Go, or whatever your stack already speaks.
- AI
LLM features
Assistants grounded on your own data, agent workflows that take real actions, and the guardrails around them.
- DI
Data & integrations
Crawlers, pipelines and integrations that turn messy external data into something your product can rely on.
- PD
Product design
Research, UX and UI by designers who sit in the same squad as the engineers building it.
- PO
Platform & DevOps
Cloud, CI/CD and observability with security from day one. Port 443 is in the name for a reason.
- QA
Quality & evals
Test automation and LLM eval suites wired into CI, so regressions get caught before your users find them.

AI in how we build, in what we ship, and in how we keep it safe.

Several squads in flight at any time. One accountable lead for every partner.
Selected work
Most of our clients prefer to stay unnamed. Here’s the shape of it.
One clean feed from a long tail of carrier data
Crawlers, APIs and file drops from carriers across Europe, normalized into a single pipeline their pricing and ops teams query every day.
A support assistant customers actually trust
An in-product assistant grounded on docs and account data, with an eval suite in CI, plus the marketing site and lifecycle emails around the launch.
How we work
Start small. Expand as trust grows.
Paid discovery
A few weeks with the people who will actually build it. Scope, risks and what done looks like.
First squad
A dedicated squad ships in weekly increments, AI-assisted, with human review on everything.
Prove it
We agree on outcomes upfront and measure against them, release by release.
Expand
Add squads, take on more of the roadmap, or hand over cleanly to your own team.
