After Openwave, John would go on to start Sonos, the wireless speaker company.
At Openwave, Kevin worked closely with Thomas Reardon. Things came full circle when Reardon started Ctrl Labs in 2017, and Kevin became his first investor. In 2019, Ctrl Labs sold to Facebook.
During his six years at Twitter, Kevin saw the service evolve from a social networking toy to changing the future of media.
“To me, there’s a simple formula for venture capital: be curious, hustle, be a good human, and invest in great companies. If you invest in great companies, you’ll get to invest in more great companies. There’s no other secret.”
Kevin knew he had to invest in Mirror after the first time he tried the product. “I remember running out of the pitch meeting to catch Brynn before she got on the elevator. I couldn’t let her leave without making an offer.”
