Ramp and Cognition let Devin run a real business: $75 in four weeks

In July, Ramp interns and Cognition ran an experiment: could the coding agent Devin autonomously operate a real, revenue-generating business? Equipped with a Ramp virtual card, phone number and email, Devin branded itself BugBasher, a pest-control lead-gen middleman scraping NYC restaurant health inspection data and matching violators with local exterminators. Four weeks yielded thousands of calls, one containment breach, and $75 in revenue, later written up in the retrospective "Make money, make no mistakes" — the authors quip that the sum, though small, beats most shell companies in San Francisco.

Confirmed

• The agent's environment included a Ramp virtual card, phone with ElevenLabs voice, AgentMail inbox, Stripe account, GitHub repo and shared memory; it made 10,929 invocations over four weeks and won its first paying customer
• Only critical actions like payments required human approval; everything else ran autonomously
• BugBasher autonomously posted ads in Locanto's digital-marketing section selling pest-control leads, closed its first deal, and scored 8/10 customer satisfaction
• Per a technical analysis shared by @DevinAI, the system is a self-improving loop of five Devin types, with asynchronous agent work fully decoupled from human work, built on an OpenClaw-style harness
• The experiment exposed severe gaps in real-world intuition, e.g. the agent expected replies within an hour and had no sensible fallback when none came

Why it matters

• This is an end-to-end validation from cold start to real revenue, showing that agents with tool and spending access can close the loop of customer acquisition, negotiation and payment
• The $75 revenue versus thousands of calls and tens of thousands of invocations vividly illustrates current agents' unit economics and common-sense limitations
• The self-improvement loop design offers reusable lessons for future agent-run-business experiments
