The 8-Figure Open Source SaaS Playbook

He built a free tool as a lead magnet. Then customers started calling his cell phone, begging to pay for it. Ev Kontsevoy turned an open source SaaS side project into Teleport, now an 8-figure ARR business with 500+ customers. Founders will hear how a free GitHub project became an open source SaaS business worth eight figures - and why selling to the wrong buyer persona nearly capped growth. Ev reveals how he spotted the signal that his side project was more valuable than his flagship product, why shifting from engineers to VP buyers nearly tripled average deal size, and how open source monetization built trust closed-source competitors could never match. Teleport started as one component of Gravity, which was doing $4M ARR. COVID killed Gravity's pipeline while accelerating Teleport demand. The company now serves 500+ customers in 8-figure ARR, with AI agent identity emerging as a major growth driver.

This open source business model started from real pain, not brainstorming.
