Index Ventures, an international venture capital firm, led a $103m series B funding round in Temporal, an open-source, stateful, microservices orchestration platform, with participation from Sequoia Capital, Amplify Partners, Madrona Venture Group and Addition Ventures. “The challenges Samar and I saw at Amazon 15 years ago are the same challenges in front of almost every company today. The average business application now lives across dozens of stateful servers and services, which has been great for flexibility and scale, but it’s also made applications increasingly brittle and difficult to troubleshoot or enhance,” Maxim Fateev, Temporal co-founder and CEO.
