Full-Stack Ghostwriter at Udemy
Bucharest, Romania
Summary
👤
Senior🎓
Top SchoolSebastian Neferu is a full-stack ghostwriter and GTM architect with eight years of experience turning technical IP into compounding inbound growth for Series A B2B AI SaaS founders. He designs and ships three production-grade engines—Activation (education-first email courses), Authority (founder-led LinkedIn thought leadership), and Retention (high-signal newsletters)—that measurably lower CAC, lift trial-to-paid activation, and boost LTV. Combining a developer’s fluency (web dev, automation stacks like Make/n8n, Airtable) with seven years teaching 40,000+ students and hands-on high-ticket sales experience, he translates complex product docs and changelogs into founder-forward content that engineers respect and prospects act on. He also builds the AI and automation layers only when they amplify proven assets, ensuring voice-preserving scale rather than generic AI output. Based in Bucharest, he’s consulted 100+ founders and delivered full-funnel content systems—not just words on a page—that founders forward to their CTOs.
