Who We Are

Baton Corporation is the development company that builds and operates the entire technology stack behind pump.fun, the largest memecoin launchpad in production today. The systems are low latency, high throughput, live under constant load, and break if you get them wrong.

• Solve complex technical challenges related to crypto wallets, smart contract interactions, and real-time data updates.

• Maintain a clean, modular, and scalable codebase while pushing the boundaries of mobile development.
