About
Speedscale is a Kubernetes-native performance testing platform that eliminates the gap between staging and production environments — capturing real user traffic from production, sanitizing it of personal data, and replaying multiplied versions of that traffic as load tests to validate that new code will perform as expected under real production conditions. Founded in 2020 and a Y Combinator W20 graduate, Speedscale raised $19.6 million including a $9 million round led by Grotech Ventures in March 2023, serving customers including Sephora, Vistaprint, and Zenni Optical.
Mux is the video API platform powering Vimeo, Robinhood, CBS, and TED with streaming infrastructure and analytics, generating $46M revenue in 2024 and valued at $1B+.
About
Mux is a video infrastructure company that provides APIs for developers to build streaming video experiences without managing the complex encoding, delivery, and analytics infrastructure that professional video requires. Founded in 2015 by Jon Dahl, Steve Heffernan, Matthew McClure, and Adam Brown—the team behind video.js, the most popular open-source HTML5 video player—Mux brought deep video expertise to the API-first approach that companies like Twilio and Stripe had proven for communications and payments.
