“I fractured the metatarsal bone in my right foot and found myself immobile — with Claude Code. Two weeks later, I prototyped and launched NinjaPear, a B2B company intelligence and data enrichment platform. That was six months ago. We did over $15k in gross revenue last month.”
Editor's note: Steven Goh is not a beginner: he is a software engineer with more than 20 years of experience and founded Proxycurl, a LinkedIn data API that reached about $10M ARR with around 60 employees before LinkedIn sued it in January 2025; he settled and sold it. He says he was stuck at his keyboard with a fractured foot, started playing with Claude Code, and built and deployed the NinjaPear prototype in two weeks. He now pays for Codex and Claude Code plans (about $200 a month together), runs NinjaPear alone with no plan to hire, and hosts it on his own computers at home in Singapore. He is based in Singapore; the $ figure is as he wrote it and NinjaPear's prices are listed in $.
How they got customers
He launched with a blog post, then released a free 1:1 replacement for Clearbit's deprecated Logo API and replied to people on X who were looking for one. His main growth hack, on his blog: for every new signup, a prospecting agent finds people in similar roles at that user's competitors and sends them a cold email saying a competitor just signed up; he credits it with taking registrations from 300 to 3,163 users in five months. He also writes long guides and reviews on the company blog.
