Senior SWEs at PlanetScale own major subsystems of the serverless MySQL platform — Vitess sharding, query routing, database branching, schema change management, or serverless infrastructure. At PlanetScale's company size, senior engineers have company-wide architectural influence. The open-source Vitess foundation means contributions are publicly visible, building professional reputation. The $1.2B valuation creates higher risk/reward equity dynamics.

Global Levers
- Database Subsystem Ownership: "I own major subsystems of a production database platform. At this level, my decisions affect data correctness and performance for every PlanetScale customer."
- Open-Source Visibility: "My Vitess contributions are publicly visible on GitHub. This public technical leadership builds both PlanetScale's brand and my career."
- Earlier-Stage Premium: "PlanetScale at $1.2B has significant growth potential. A 3-5x valuation increase is realistic, making my equity grant substantially more valuable."
- Cockroach Labs/MongoDB Counter: Both offer equity at higher valuations or liquidity. Push for larger PlanetScale grant.
Negotiate Up Strategy: "I'd like equity at $250K over 4 years with acceleration. At senior level, I own database subsystems where correctness is non-negotiable, and the $1.2B valuation warrants a larger grant." Counter at $210K-$240K equity is strong.
