How We Worked Agent-first development — we started with a stenographer (transcription, summarization, email), validated infrastructure, then added complexity. Four phases: stenographer, intake agent, portal, and integrations. Each had defined criteria and working deliverables. Real call recordings built our test dataset covering edge cases. Every AI change ran against hundreds of test cases before being deployed. Twice-weekly calls kept alignment tight. Result Thousands of calls monthly. 95% case capture rate. 1.2-second response latency. 80-90% cost reduction vs traditional answering services. Zero missed leads, consistent quality, and attorneys reclaim hours for billable work.
