Twenty+One / For CTOs
Keep your team. Add a crew.
Your engineers belong on your core product: not on a year of platform engineering to make AI delivery safe, or on the migration nobody wants. Your crew takes the workstreams your team never reaches, ships into repositories your engineers can read line by line, and answers to the same standards you hold your own team to.
The open kitchen.
You want to know how it works before you trust it. Good; that's the right instinct. We run technical deep-dives for CTOs and engineering leads: the architecture principles, the quality gates, the model-eval process, the audit trail. No mystery, no magic claims. What you'll see is why this is a platform, not a prompt.
Why not build it yourself?
You could: the pieces are public. But making AI an integral, risk-maintainable part of delivery isn't a project, it's a subscription: a platform team you fund forever, re-doing its own work every quarter as the stack churns. We are that team, amortized across every client. Spend your engineers on your product. Buy the treadmill.
Your code stays yours. On your terms.
We deliver into your repos, your CI, your standards, but we don't need your codebase on day one. Most engagements start greenfield: a new module or product line alongside your core, integrating through APIs, zero code sharing. Access grows only as shipped work earns it, one bounded context at a time, logged and revocable. And the terms are standard, in writing: everything we ship is yours, we never train on your code, and every client runs on a dedicated single-tenant instance (your agents and your infrastructure, not a slice of a shared pool) with EU residency. And you can leave anytime with all code plus documentation your own team can maintain: the platform is how your software gets built, never what it needs to run, so what ships is standard code on your stack, deployable and maintainable without us. Some things should stay behind your wall; we'll work around them.
The Sideline Sprint.
Pick the epic your team never gets to. We run it through the crew: two sprints, your review on every line, pay only for accepted points. Your data, your control, no bet.
