Railway Raises $100 Million As AI Coding Pushes Cloud Deployment Claims

Railway has raised $100 million in a Series B round to expand its global data-center footprint, grow beyond its 30 employees and build a formal go-to-market operation after five years of relying largely on developer referrals.

TQ Ventures led the financing, with FPV Ventures, Redpoint and Unusual Ventures participating.

The San Francisco cloud platform says AI coding tools are creating more software faster than conventional infrastructure can deploy it, exposing the limits of older cloud systems.

Railway had raised $24 million before the new round, including a $20 million Series A led by Redpoint in 2022.

Founder and chief executive Jake Cooper said the company raised to accelerate its trajectory rather than to extend its runway.

Railway has more than two million developers, processes over 10 million deployments each month and handles more than one trillion requests through its edge network.

Revenue grew 3.5 times last year and continues to rise 15 percent month over month.

Capital and operating problem

Cooper said AI coding assistants such as Claude, ChatGPT and Cursor can generate working code in seconds, while a standard Terraform build-and-deploy cycle takes two to three minutes.

Railway claims its platform can deploy in under one second, a speed it considers necessary as software agents begin creating and testing services continuously.

Customers report a tenfold increase in developer velocity and up to 65 percent lower costs than traditional cloud providers.

At G2X, which serves 100,000 federal contractors, chief technology officer Daniel Lobaton measured deployments at seven times the previous speed and cut the infrastructure bill from $15,000 per month to approximately $1,000.

He said work that once took a week could be completed in about a day, including launching six services in two minutes.

Infrastructure built for faster deployment

Railway moved away from Google Cloud in 2024 and began building its own data centers to control the network, compute and storage layers.

Cooper linked that vertical integration to faster build-and-deploy cycles.

He also said Railway remained online during recent widespread outages affecting major cloud providers, though the source did not provide independent uptime benchmarks.

The company says its pricing is roughly 50 percent below hyperscale providers and three to four times lower than newer cloud startups.

It charges by actual usage rather than idle capacity: $0.00000386 per gigabyte-second of memory, $0.00000772 per vCPU-second and $0.00000006 per gigabyte-second of storage.

Idle virtual machines are not billed.

The platform supports PostgreSQL, MySQL, MongoDB and Redis, with up to 256 terabytes of persistent storage, more than 100,000 input/output operations per second and deployment across four regions in the United States, Europe and Southeast Asia.

Enterprise customers can scale to 112 vCPUs and 2 terabytes of RAM per service.

Enterprise expansion and market position

Railway says 31 percent of Fortune 500 companies use its platform, although those deployments range from company-wide infrastructure to individual team projects.

Customers named in the coverage include Bilt, Intuit’s GoCo subsidiary, TripAdvisor’s Cruise Critic and MGM Resorts.

Kernel, a Y Combinator-backed AI infrastructure company serving more than 1,000 businesses, runs its customer-facing system on Railway for $444 per month.

Enterprise controls include SOC 2 Type 2 compliance, HIPAA readiness, business associate agreements on request, single sign-on, audit logs and a bring-your-own-cloud option.

Add-ons include extended log retention for $200 per month, HIPAA BAAs for $1,000, enterprise support with service-level objectives for $2,000 and dedicated virtual machines for $10,000.

Railway competes with Amazon Web Services, Microsoft Azure and Google Cloud Platform, as well as Vercel, Render, Fly.io and Heroku.

Cooper said Railway covers VM primitives, stateful storage, virtual private networking and automated load balancing rather than focusing only on containers.

The company has also built integrations that let Claude call deployments and analyze infrastructure, and released a Model Context Protocol server in August 2025 for deploying applications from code editors.

The next phase

Railway hired its first salesperson last year and has only two solutions engineers.

Most of its two million users arrived through word of mouth, without paid marketing.

Its investor roster includes GitHub co-founder Tom Preston-Werner, Vercel chief executive Guillermo Rauch, Cockroach Labs chief executive Spencer Kimball, Datadog chief executive Olivier Pomel and Linear co-founder Jori Lallo.

The new financing will now fund the data-center expansion, additional hiring and Railway’s first full go-to-market effort.

Cooper said 2026 would be the year the company begins operating on a broader public stage.
