Render has raised $100 million in a Series C extension at a $1.5 billion valuation, bringing total funding to $258 million as the cloud startup positions itself as the infrastructure backbone for AI applications and autonomous agents.

The funding, led by Georgian Partners with participation from Addition, Bessemer, General Catalyst, and 01A, comes as traditional cloud infrastructure proves fundamentally misaligned with AI agent execution patterns. While web applications rely on stateless request-response cycles, AI agents demand long-running, stateful, and distributed execution that existing platforms struggle to support.

Railway raised $100 million in Series B funding as AI coding assistants create a fundamental mismatch between code generation speed and deployment infrastructure, with the company claiming sub-second deployments versus the 2-3 minutes required by traditional cloud tools.

The funding round, led by TQ Ventures with participation from FPV Ventures, Redpoint, and Unusual Ventures, positions Railway to challenge Amazon Web Services, Google Cloud, and Microsoft Azure with infrastructure purpose-built for the AI development era. Railway has attracted 2 million developers with zero marketing spend, processing over 10 million deployments monthly and handling more than one trillion requests through its edge network.
