Berlin’s Restate raises $20M to build out US business
The German infrastructure startup will use its Series A to develop its software and expand in the United States, including a new San Francisco commercial hub.
Berlin-based Restate has raised $20 million in Series A funding to develop its software infrastructure and expand in the United States, including a new commercial hub in San Francisco. European venture capital firm Singular led the round, with participation from US investors Redpoint Ventures and Capital One Ventures.
The financing, announced on September 30, brings Restate’s total funding to $27 million. Founded in 2024, the company develops “durable execution” infrastructure: software that records completed work so applications can resume correctly after crashes, network interruptions or other failures, rather than requiring developers to build recovery mechanisms into every step.
The US expansion builds on adoption that Restate says already spans hundreds of companies, including Fortune 500 businesses. Its announcement names Replit, DOSS and BILT Rewards among users, giving the company customer references as it invests in a larger commercial presence.
A commercial foothold for infrastructure sales
The San Francisco hub is the clearest operational commitment in the funding announcement. Restate has not disclosed an opening date, a staffing target or how much of the round will be allocated to US expansion rather than product development.
Strategically, the move is about commercialising infrastructure already being used in production, not simply introducing a new product to the market. Restate is targeting both AI applications and enterprise workflows, positioning reliability as a shared requirement across those customer groups. The participation of two US investors adds an American financing connection alongside the planned commercial hub.
Replit provides a concrete example of the product’s role. In Restate’s announcement, Michele Catasta, Replit’s president and head of AI, said the company selected Restate while evolving its agent architecture. “It now handles all durable orchestration at Replit, giving us the flexibility to rapidly expand what our agent platform can do,” he said.
Why AI agents change the reliability problem
Restate’s pitch is that AI agents make software recovery more demanding. Agents can run continuously, call models and external services, use tools and interact with people or other agents. When work is interrupted, the infrastructure must preserve not only an individual task’s progress but also the state and communications surrounding it.
“Durable execution solved an important problem: it made individual processes reliable,” said Stephan Ewen, Restate’s CEO and co-founder. “But software is increasingly made up of services, agents, workflows, and state that all need to stay reliable as they interact. We believe durability has to become a property of the infrastructure itself.”
The company’s technical differentiation centres on a purpose-built distributed log and an event-driven orchestrator. Rather than placing durable execution on top of a general-purpose database, Restate uses that log as the foundation for execution, state and communication. According to the company, this creates a self-contained system that does not require an external database or search system.
Restate has also recently introduced a Bring Your Own Cloud offering. It lets customers run a fully managed deployment inside their own cloud account and virtual private cloud while keeping application data within their infrastructure. That deployment option gives the commercial team a way to address customers that want managed software without moving application data outside their own environment.
Building on Apache Flink
Restate’s founding team includes creators of Apache Flink, the open-source stream-processing framework used in real-time data systems across banking, streaming media and software-as-a-service businesses. Alongside Ewen, its co-founders are Igal Shilman, Till Rohrmann and former Stripe and Meta executive Ahmed Forghal.
That background supplies an infrastructure track record, but the next step is commercial execution. The new funding pairs continued product development with a US sales foothold, as Restate seeks to turn adoption of its reliability layer into a broader business across AI agents and enterprise applications.
