The financing was led by Kleiner Perkins with participation from existing investors a16z, SignalFire and Insight Partners, as well as Tom Preston Werner (co-founder and CEO of GitHub), Jack Altman (CEO and founder of lattice), and Max Mellen (co-founder of Instacart). Kleiner Perkins Partner Bucky Moore will join the PlanetScale Board of Directors. The Series C round brings the total capital raised by PlanetScale to $105 million. PlanetScale plans to use the funding to accelerate research and development and expand go-to-market activities globally for the company's infinitely scalable and easy-to-use serverless MySQL database.

PlanetScale is upending the database industry with a true serverless experience that takes the headache out of database management. Database imports, alongside branching, sharding and non-blocking schema changes increase developer velocity while reducing database fragility and ensuring production databases never have downtime. PlanetScale is built on battle-tested Vitess, a graduated CNCF open source project used by GitHub, HubSpot, Slack and Square to serve millions of queries per second. PlanetScale reduces time-to-market for new applications and eliminates the cost and effort of managing database infrastructure.
