The angle

Why this shape works.

Every founder can prototype an AI wrapper in a weekend; almost none can ship the production shape: retrieval that stays accurate, token costs that don't eat margin, rate limits, evals, and billing that meters usage. Yo! Launch ships the whole shape, because we build these for our own products too.

What ships

Included in your 30-day sprint.

Scope is locked at kickoff, anything not on this list is free during the sprint. Best fit for the The 30-day launch.

  • Chat or agent UI with streaming responses
  • RAG pipeline over your documents / data (embeddings + retrieval)
  • Model routing (Claude / GPT) with fallback and cost caps
  • Usage metering per account with plan limits
  • Stripe Billing with usage-based or seat pricing
  • Eval harness so quality is measured, not vibes
