Ev Kontsevoy, Teleport
The 8-Figure Open Source SaaS Playbook
Ev Kontsevoy is the co-founder and CEO of Teleport, an infrastructure identity platform based in Oakland, California. Teleport helps organizations manage secure access to their computing environments by unifying human, machine, and AI agent identities into a single layer. Before Teleport, Ev founded Mailgun in 2009, an email API for developers that was acquired by Rackspace in 2012. After the acquisition, he spent time at Rackspace listening to customer problems, which led him to start Gravitational in 2015. The original product, Gravity, helped SaaS companies deploy their applications across multiple cloud environments. But the real open source SaaS story started when Ev built Teleport as one component of Gravity - a free, Apache-licensed tool for managing secure access. He intended it purely as demand generation for the paid Gravity product. Then COVID hit. Gravity's pipeline dried up overnight while Teleport's inbound demand exploded as engineers scrambled for remote access solutions. The pivot was not really a pivot. Ev focused on one product, rebranded the company as Teleport, and launched an enterprise version. The first enterprise deal closed on an improvised phone call for $25,000 per year. Early on, they sold to individual engineers through a product-led open source SaaS motion. But when Ev asked customers to "sell Teleport back to me," he discovered they were using only a fraction of the platform. They were selling to the wrong buyer. Switching from practitioners to VPs of platform engineering nearly tripled the average deal size in a single year. Teleport now serves over 500 customers in eight figures of ARR, with AI agent identity emerging as a major growth driver - what Ev calls "COVID 2.0" for the business.
