Replicas runs coding agents such as Claude Code, Codex and Cursor in isolated cloud Linux VMs and returns pull requests for review, and it announced a $4 million seed round on Oct. 13, 2026. CEO Connor Loi announced the round on the San Francisco startup's blog. Backers include Y Combinator, Flex Capital, Founders' Co-op, Pioneer Fund, Robinhood Ventures, Twenty Two Ventures, Metsu Capital and Blast, according to the post. Angel investors include Y Combinator co-founder Paul Graham, Resend founder Zeno Rocha, Graphite co-founder Merrill Lutsky and Privy co-founder Henri Stern, Loi wrote.
Very Frontier reported that Loi and CTO Saai Arora founded the company in 2026 and that it took part in Y Combinator's Spring 2026 batch.
One machine per agent
Replicas describes itself on its website as a cloud coding-agent platform for engineering teams, with each agent working in its own Linux VM. Teams can start work from Slack, Linear or GitHub, according to the site.
Loi's case for this is about scale. In his post, he wrote that engineers he knew went from running one Claude Code terminal to running 3 to 5 agents in roughly six months. "A laptop can't hold hundreds of agents that each need their own environment, so every agent needs a machine of its own, and you need one place to manage them all," he wrote.
According to Very Frontier, each Replicas environment comes set up with the chosen repository, tools and dependencies, so an agent can install packages, run services and tests, check failures and revise its work before opening a pull request. The outlet also reported that agents can respond to failed CI checks and code review comments.
Usage so far
Loi wrote that Mintlify and Knowunity run their agents on Replicas every day. Customers crossed 1 million minutes of agent usage in May, 2 million in July and 5 million in September, he wrote, and three weeks after that they were at almost 7 million. He also said agents have run in more than 1 million workspaces.
These are company figures. Very Frontier noted that Replicas has not disclosed a valuation or revenue, and that the usage numbers show activity, not profitability.
Pricing and competition
Replicas charges by the minute for its cloud workspaces, with plans starting at $50 a month and $100 of free usage for new users, according to its pricing page. Model costs are billed separately through each customer's own model provider account, the page says.
Very Frontier named Daytona, E2B, Modal and CodeSandbox among companies offering related infrastructure, and said Replicas is betting on handling the full coding workflow, not just the sandbox.
Loi wrote that Graham called Replicas the "manager" company when the founders visited him in Palo Alto. The company is hiring, according to the post.
