We Build What
AI Makes Possible

Our typical MVP sprint is 2–4 weeks from kickoff to a deployed, investor-ready build. Larger systems run on 4–8 week cycles with weekly demos.
Yes, always — before any discovery call if you'd like. We work with confidential ideas every week and have a standard mutual NDA ready to send.
You do, end of contract. We deliver the full repo, infrastructure-as-code, and credentials. No vendor lock-in.
Expected — we work in weekly sprints, so you can re-prioritize at any sprint boundary without renegotiating the whole engagement.
We pick the right model per task — Claude for reasoning, GPT-4 for tools, open-source (Llama, Mistral) for cost-sensitive workloads, and pgvector or Pinecone for retrieval.
Yes. We start with a paid 1-week audit (codebase, infra, migrations) and give you a written report + recommended path forward — no obligation to continue.
