Case study

Code is private
Problem

An offer used to go out as a bare number. Accepting it is a trust decision, and a number alone gives the customer nothing to trust — no comparables, no reasoning, no answer to "why is this fair?"

What it does

For every quote, the system researches comparable sales, uses an LLM judge to select the strongest comps, and runs a self-correcting generator that writes a pitch grounded in them — so each offer arrives with its argument attached, automatically.

Architecture
  1. 01Quote created (event-driven trigger)
  2. 02Comparable research
  3. 03LLM-judge comp selection
  4. 04Pitch generation
  5. 05Self-correction pass against the evidence
  6. 06Pitch attached to the offer
Stack
  • TriggerEvent-driven backbone (SQS + Lambda)
  • ResearchComparable retrieval over sales data
  • SelectionLLM-as-judge scoring
  • GenerationSelf-correcting LLM pipeline
  • RuntimePython on AWS
Outcomes
  • Offer acceptance more than doubled in phase one: 11.5% → 26%
  • Every quote ships with an evidence-backed pitch, no human in the loop

Code is private — happy to walk through it.

Curious how this would look on your problem?
