What does it take to change the world? Sometimes, it starts with a single email.

On February 18, 2006, Techstars Founder & CEO David Cohen sent a message to Co-Founder David Brown with a simple but ambitious idea: to build something that would help founders succeed. Nearly two decades later, that idea has grown into the original mentorship-driven accelerator, having supported more than 11,000 founders around the world.

This year, Techstars turns 20. It's a milestone worth pausing to celebrate, not just as a measure of longevity, but as a testament to what happens when a community rallies around a shared belief: that the best investment you can make is in people.

From a scrappy first accelerator class in Boulder, Colorado, to global programs spanning almost every continent, Techstars has always been about more than capital. It's been about mentorship, connection, and a genuine commitment to Give First. That philosophy, baked into Techstars' DNA from day one, is what has made the network so enduring and so meaningful to the founders who've come through it.

As we look back on two decades of breakthroughs and evolution, the story of Techstars is really the story of thousands of founders who dared to build, supported by a community that showed up to help them do it.
