由 Apache Flink 的创始人创立的柏林初创公司 Restate 已完成了一轮 2000 万美元的 A 轮融资。该公司致力于构建能够确保 AI 代理程序及后端软件在系统故障情况下仍能持续运行的基础设施。Restate 在周三发布的声明中表示，本轮融资由 Singular 领投，Redpoint Ventures 和 Capital One Ventures 也参与了投资；目前该公司的总融资额已达到 2700 万美元。
Restate, a Berlin startup founded by the creators of Apache Flink, has raised a $20m Series A. It builds infrastructure that keeps AI agents and backend software running through failures. Singular led the round, with Redpoint Ventures and Capital One Ventures, the company said in a statement on Wednesday. Its total funding is now $27m.
“Restate 最初并不是为专门用于处理 AI 代理程序而开发的，但它恰好能够完美解决所有与这些代理程序相关的问题，”该公司首席执行官 Stephan Ewen 告诉 TechCrunch。
“It never was built for agents in the beginning, but it just happened to be a perfect match for all these problems that agents surface,” Stephan Ewen, its CEO, told TechCrunch.
Restate 的核心功能是确保软件运行的稳定性：它会记录程序的执行过程，从而在系统崩溃、重启或网络连接中断后仍能保证程序正常运行。不过，Ewen 表示，AI 代理程序的复杂性增加了这一任务的难度——因为它们通常会运行更长时间，并在运行过程中调用各种模型、工具、API 以及其他代理程序。
What durable execution does Restate sells durable execution. The software records what a program has already done. That lets it carry on correctly after a crash, a restart or a dropped connection. AI agents make this harder, the company says. They run for longer and call models, tools, APIs and other agents along the way.
Restate 并不依赖通用数据库，而是使用自己开发的分布式日志系统来存储执行记录、程序状态及通信数据。该公司最近推出了 “Bring Your Own Cloud” 服务，允许客户在自己的云账户中部署和管理 Restate 的功能。
Restate does not build on a general-purpose database. It uses its own distributed log as the base for execution, state and communication. The company recently launched Bring Your Own Cloud, which runs a managed version inside a customer’s own cloud account.
据 Restate 称，已有数百家公司正在使用其产品，其中包括 DOSS、Bilt Rewards 以及多家 Fortune 500 强企业；Replit 也将其自身的代理程序迁移到了 Restate 平台上。Ewen 在一篇博客文章中写道，新版本的代理程序能够执行比旧版本多 10 倍以上的稳定操作。
Hundreds of companies use Restate, it says, including DOSS, Bilt Rewards and Fortune 500 firms. Replit moved its Replit Agent onto Restate. The new agent design uses over 10 times as many durable actions as the old one, Ewen wrote in a blog post.
“现在，Replit 的所有代理程序调度任务都由 Restate 负责处理，这让我们能够灵活地扩展该平台的功能，”Replit 的总裁兼 AI 负责人 Michele Catasta 表示。
“It now handles all durable orchestration at Replit, giving us the flexibility to rapidly expand what our agent platform can do,” said Michele Catasta, Replit’s president and head of AI.
Ewen 向 TechCrunch 表示，与 Temporal 相比，Restate 在最近几个月内已经成功签订了多份价值六位数至七位数的客户合同。根据 TechCrunch 的报道，Temporal 是该领域的领先者；该公司在 9 月份完成了 5.5 亿美元的 E 轮融资，估值达到了 125.5 亿美元。
Up against Temporal Restate has closed several six- and seven-figure customer contracts in recent months, Ewen told TechCrunch. Temporal leads the field, according to TechCrunch. It raised a $550m Series E at a $12.55bn valuation in September.
埃文（Ewen）共同创建了 Apache Flink——一个开源的流处理框架。之后，他担任了基于该框架成立的公司 Data Artisans 的首席技术官（CTO）。2019 年，阿里巴巴收购了 Data Artisans 并将其更名为 Ververica。2022 年，埃文与前同事伊加尔·希尔曼（Igal Shilman）和蒂尔·罗尔曼（Till Rohrmann）共同创立了 Restate。据 TechCrunch 报道，前 Stripe 和 Meta 公司的工程师艾哈迈德·法尔加尔（Ahmed Farghal）在 A 轮融资时加入了 Restate 的团队，成为公司的第四位联合创始人。
Ewen co-created Apache Flink, an open-source stream processing framework. He was then CTO of Data Artisans, the company built around it. Alibaba bought Data Artisans in 2019 and renamed it Ververica. Ewen founded Restate in 2022 with former colleagues Igal Shilman and Till Rohrmann. Ahmed Farghal, a former Stripe and Meta engineer, joined as the fourth co-founder with the Series A, TechCrunch reported.
Restate 将利用这笔资金招聘市场推广团队以及更多的工程师，并在旧金山设立一个商业办事处。今年 7 月，Runta 公司为其 AI 代理基础设施项目筹集了一笔由 a16z 领投的种子轮融资。
Restate will use the money to hire a go-to-market team and more engineers. It will also open a commercial hub in San Francisco. In July, Runta raised a seed round led by a16z for its AI agent infrastructure.
