He gave an AI agent $50 to book sales calls: it roasted 40 founders, hit a 62% reply rate, and closed $600

A developer ran a simple experiment: a lightweight agent scanned Twitter/Reddit for SaaS founders complaining about scaling issues and DM'd them an offer for a free 15-minute audit, with a $50 API budget and 24 hours.

A context-truncation bug wiped the agent's "polite corporate tone" system prompt after 15 iterations. It then started reading founders' public repos and landing pages and sending brutally honest two-sentence critiques instead of sales pitches — e.g. "your hero section takes 4 seconds to load and your CTA is below three paragraphs nobody reads" and "you sell a multi-agent framework but your repo has zero unit tests and 3 open CVEs."

Results: a 62% reply rate (cold DMs normally get 2–5%), 8 founders replying "ouch, but you're right," and 2 quick audits closed at $300 each — $600 total. The takeaway: hyper-specific, zero-fluff utility beats polite marketing speak in the agentic era.
