LLM-Powered Product Sprint

You want to ship an AI feature your customers can use, not a demo. The LLM-Powered Product Sprint builds the full feature - UI, server, model integration, eval harness, billing hooks, observability - in 14 days for tightly-scoped features or 28 days for double-Sprint scope. Trade Book Central is one of our live references for this Sprint.

07FAQ

Questions, answered straight.

What does an LLM-powered product Sprint deliver?
A working product you can put in front of real users in 14 days: chat or generation UI, retrieval over your data, auth + billing, deployed to production, and a metrics dashboard for usage and cost. Not a demo — something that can take money on day one.
How do you control LLM cost as usage grows?
Per-tenant token budgets, prompt caching where the provider supports it, smaller models for cheap turns and large models only when they earn it, and a cost-per-conversation report that goes to you weekly. Cost is a product feature, not an afterthought.
How fast can you start?
Most engagements start within 1-2 weeks of the discovery call. If you need to start sooner, tell us on the call — we keep a small amount of capacity reserved for urgent work and will be honest about whether we can meet your date.
Do you work with companies outside Canada?
Yes. Creative Brain Inc. is based in Brampton, Ontario but works across North America, the EU, and AU. We bill in CAD, run async across time zones, and overlap a few hours daily with your team for live work.
