How We Cut a Fintech's CAC 31% with One Agent
The Challenge
A Series B fintech company was receiving 400+ signups a week. A team of three SDRs manually googled each company size, funding data, and geographic location to score leads. The process took 3-5 days per lead, causing high latency, cold followups, and a bloated customer acquisition cost.
The Solution
We built a self-healing n8n workflow. The moment a lead registers: (1) n8n catches the webhook, (2) triggers a background web scraping agent to gather company size and public data, (3) queries Claude 3.5 Sonnet to classify lead category and high-value intent, and (4) automatically routes scored SQL opportunities directly to sales reps in Slack with a pre-written personalized outreach template. The latency was cut from 4 days to 4 seconds.
The Receipts
- 31% Reduction in customer acquisition cost (CAC)
- Lead qualification time reduced from ~72 hours to under 5 seconds
- Sales response rate increased by 2.4x due to real-time Slack triggers
- Saves 110+ manual ops hours every single week
