PlanetScale
PlanetScale is a San Francisco database company that turns the hard parts of running relational databases at scale into a managed cloud service. Founded in 2018 by the creators of Vitess - the MySQL-sharding system built at YouTube and later used by Slack, GitHub and Square - the company sells a serverless database platform known for non-blocking schema changes, branching workflows borrowed from Git, and, more recently, Metal instances built on locally-attached NVMe drives. In 2025 it extended the same platform to Postgres, chasing the fastest-growing part of the database market while still, in its own words, loving MySQL.
PraSaga Foundation
PraSaga Foundation is a non-profit blockchain organization building SagaChain, a layer-one blockchain that replaces smart contracts with programmable 'smart assets' - first-class objects that model real-world things directly on-chain. Founded in 2017 by Michael Holdmann and David Beberman, PraSaga pairs a natively sharded architecture with a hybrid Proof-of-Work/Proof-of-Stake consensus and a Python-based developer stack (SagaOS, SagaPython) to target the scalability, cost, and usability limits of first-generation chains. Its native SagaCoin uses a dynamic monetary policy aimed at stable purchasing power. A public development testnet went live in 2025.
