Railway Raises $100M Series B to Rebuild Cloud for AI Code

Railway raised $100 million to scale its developer-first cloud platform. The bet: AI-generated code exposes how slow legacy cloud primitives really are.

Railway raised $100 million in a Series B round led by TQ Ventures to scale its developer-first cloud platform, which now serves more than 2 million users and 31% of the Fortune 500. Founder Jake Cooper argues that legacy cloud primitives have become the bottleneck as AI coding assistants ship code in seconds, while traditional deploy pipelines still take minutes. The funding will fund global data center expansion, hiring, and new tools built specifically for AI-generated workloads.

A funding round built around a simple pitch

Railway, a San Francisco-based cloud platform that has quietly amassed more than two million developers without spending a dollar on marketing, announced on Thursday that it raised $100 million in a Series B round, as surging demand for AI applications exposes the limits of legacy cloud infrastructure.

TQ Ventures led the round, with participation from FPV Ventures, Redpoint, and Unusual Ventures. The investment values Railway as one of the more significant infrastructure startups to emerge during the AI boom, capitalizing on developer frustration with the cost and complexity of incumbents like AWS, GCP, and Azure.

"As AI models get better at writing code, more and more people are asking the age-old question: where, and how, do I run my applications?" said Jake Cooper, Railway's 28-year-old founder and CEO, in an interview. "The last generation of cloud primitives were slow and outdated, and now with AI moving everything faster, teams simply can't keep up."

Scale without the marketing machine

The funding is a dramatic acceleration for a company that has charted an unusual path through cloud computing. Railway raised just $24 million in total before this round, including a 2022 check from Redpoint. The company now processes more than 10 million deployments monthly and handles over one trillion requests through its edge network, metrics that rival far larger, better-funded competitors.

Its customers include 31% of the Fortune 500, alongside names like Bilt, Intuit's GoCo, TripAdvisor, MGM Resorts, and Cruise Critic. Early adopters report a 10x increase in developer velocity and cost savings of up to 65%, according to Railway. The company is growing by roughly 200,000 new developers a month.

The core pitch is timing. A standard build-and-deploy cycle using Terraform, the industry-standard infrastructure-as-code tool, takes two to three minutes. That delay was tolerable when engineers were also the bottleneck. Once coding assistants can produce working code in seconds, the deploy step becomes the slowest thing in the loop.

What the money buys

Railway plans to use the capital to expand its global data center footprint, grow its team, and build new tools aimed at both developers and the AI systems now shipping code on their behalf. Cooper framed the platform's edge as a full-stack rebuild of networking, compute, storage, and orchestration, rather than another layer on top of existing cloud APIs.

The broader signal is that the cloud market is splitting into two camps: the hyperscalers, optimized for massive enterprise workloads, and a growing group of developer-first challengers built for a world where every commit is potentially AI-generated. Railway's bet is that the second group is about to get a lot larger.
