Replacing a prototype backend with a production-grade AI call pipeline in 12 weeks

An AI voice platform for home service businesses had paying customers and a Series A four months out — on infrastructure that could not survive either.

The challenge

The prototype stalled past 100 calls a day, analysed calls on a five-minute batch delay, silently lost 30% of bookings to a retry-less CRM client, and produced no analytics — so every enterprise demo answered “how do I know the AI works?” with “trust us”. Hiring the three senior engineers needed would have taken 12 to 18 months.

Our approach

Four overlapping phases, each shipping a production increment rather than internal work in progress: an event-driven real-time call pipeline, an idempotent CRM sync engine, a call scoring and coaching layer, then optimisation and documented handover. Beta customers were on the new infrastructure by week five.

What we delivered
  • —Event-driven real-time call ingestion and transcription pipeline
  • —Emergency detection with escalation inside fifteen seconds
  • —Idempotent CRM sync with exponential backoff and conflict resolution
  • —Five-dimension call scoring with manager and CSR dashboards
  • —Query tuning, model routing and full documentation handover
Results

Capacity moved from 100 to 25,000 calls a day and CRM latency from five minutes to under five seconds, with sync success at 99.5% and AI spend down 60%. Customers grew from three to twenty-five within three months, and the client closed an $18M Series A on the resulting production metrics.
