AI on top of what you already run

For products with real users that want agents, voice or retrieval — not a chatbot demo. If you don't know the per-call cost yet, that's the first thing we work out.

Deliverables

What you get

  • Use-case scoping with cost and latency numbers
  • Voice agents on Twilio + ElevenLabs
  • RAG on pgvector
  • Multi-agent workflows (LangGraph or a custom tool-use loop)
  • n8n automations
  • Evals and guardrails
  • Monitoring

Pricing

How pricing works

2 weeks, ends with a working prototype and a build quote.

Every engagement is quoted on scope, not on an hourly rate. After a 30-minute call you get one written number and one date, both fixed before anyone writes code. If the scope changes later, the change is priced and agreed in writing first.
