JobNimbus

The challenge: Contractors win deals through fast, accurate estimates. Your task is to build an AI pipeline that takes property information and produces an accurate customer-facing estimate — fully automated, end-to-end, in under 24 hours.

JobNimbus is the #1 CRM for roofing and contracting (4.8★ across 12,000+ reviews, 13 years in the trade). They're betting that AI can collapse one of the most painful parts of a contractor's quoting workflow from 30+ minutes down to seconds — and they're spending $10K on a weekend to find the engineers who can prove it.
