The situation

A fast-growing B2B SaaS platform was generating more leads than its sales team could qualify. Reps spent hours on manual first-touch outreach and triage, the sales cycle stretched to 45 days, and promising leads slipped through the cracks.

What we did

We built an AI agent on Claude and LangChain, integrated with HubSpot. It qualifies incoming leads against defined criteria, enriches each record, drafts personalized outreach, and routes only sales-ready leads to reps. Everything is logged in PostgreSQL for pipeline analytics.

The outcome

First-touch contact is now 70% automated, the sales cycle shrank from 45 to 31 days, and lead conversion rose 45% in the first quarter — while customer acquisition cost fell by a quarter.

Key results

45% higher lead conversion
30% shorter sales cycle
70% of first-touch contacts automated
