The problem

Preparing a quote meant reading drawings, photos and material requirements by hand, often for hours. It had to work where customers already are, in a messaging app.

What we built

3 parts
  1. A

    An agent graph with a supervisor that plans the job and routes it to specialist sub-agents for each part of the quote.

  2. B

    Messaging-app intake for text, voice, images and documents, with a queue that handles bursts of messages and only streams replies that matter.

  3. C

    Tracing and step-level evaluation, so each change to a model or prompt is scored before release; people handle exceptions such as unavailable materials.
