Railway, a San Francisco-based full-stack cloud platform that has grown to 2 million developers without marketing, announced Thursday that it has raised $100 million in Series B funding to expand its sub-second deployment platform as demand for speed and efficiency in software development grows.
The funding round was led by TQ Ventures, with participation from FPV Ventures, Redpoint, and Unusual Ventures. Prior to this round, the company had raised a total of $24 million, including $20 million in Series A from Redpoint in 2022.
Improvements in AI coding are forcing developers to rethink their deployment strategies as traditional cloud infrastructure struggles to match the speeds required by modern workflows, Railroad CEO Jake Cooper said in a statement.
Railway now delivers deployments in less than a second, and clients report faster development cycles and lower costs.
The company processes millions of deployments each month, serves enterprise customers including Fortune 500 companies, and generates tens of millions in revenue with just 30 employees.
This new funding will support global infrastructure growth, team expansion, and the railroad’s first organized go-to-market strategy to redefine cloud development in the AI era.
