Harbor, a San Francisco startup, came out of stealth on 13 October 2026 with $10 million in seed funding to help companies manage the risks of the AI agents they deploy, and to insure what is left over. In its announcement, Harbor said the round was “led by Base10, Abstract and 8VC, in collaboration with Restive, NFX, Innovation Endeavors, Kibo Ventures, Masia and MVP Ventures.” Insurance Journal and FinSMEs both name the first lead investor as Base10 Partners.
“We started Harbor with one mission: to insure the agentic economy,” the company wrote.
Why AI agents are hard to insure
An AI agent is software that does not just answer questions but takes actions: it can send emails, move money, change records or approve requests on a company’s behalf. That is useful, but it creates a new kind of risk.
Insurance works by looking at past losses to work out how likely a problem is and how much it might cost. Car and home insurance have decades of claims to draw on. AI agents are new, so there is very little history. Harbor argues that insurers “do not have the claims history to price the risk”, and says, according to Insurance Journal, that “some insurers are excluding AI out of existing policies.”
Scale is another problem. Harbor points out that when an employee makes a mistake, existing professional liability, cyber and tech errors-and-omissions policies usually cover the damage. With an agent, Harbor says, “a mistake is repeated – possibly thousands of times – until someone notices.”
Agents also change. A company may swap the AI model underneath, give the agent new tools or connect it to new data, and each change can alter how it behaves. A risk check done once can go out of date quickly.
What Harbor says it does
Harbor describes two parts to its business. The first is software. “With our risk platform, we find every agent a company runs, measure its operational, security and regulatory risk, and block the decisions that break the company’s rules before they go through,” the company said.
According to Insurance Journal, Harbor’s risk framework is mapped to major AI rules and guidance, “from NIST AI RMF and SR 26-2 to the EU AI Act”, and Harbor measures an agent again every time its model, tools or data change.
The second part is insurance. “The measurement is what makes the risk insurable. Whatever remains, Harbor insures, with our own money behind the answer,” Harbor said. The company did not say how its insurance is backed or which insurers, if any, it works with, and it did not publish pricing.
Jesús Santos, a co-founder, told Insurance Journal: “Companies need to understand the risk of their agents, and at the current pace of adoption and development, assessing the risk at a specific point in time seems useless. There is a need for an innovative solution for managing the risk in real time.”
Who is behind it
Harbor has four founders, Jesús Santos, Daniel Elechiguerra, Cristian Bartolomé and Luis Botín, who Insurance Journal reports met at Stanford University. Harbor says its “first customers are banks and insurers in the United States, Europe and Latin America”, but did not name them. Insurance Journal and FinSMEs describe it as working with banks, insurers and other regulated companies in those regions. FinSMEs reports the money will go towards expanding operations and development.
Harbor did not disclose a valuation or any revenue figures.
What this means
- Insurance is catching up with AI agents. As companies hand real tasks to agents, someone has to pay when they go wrong. Harbor is betting that measuring the risk first is what makes it possible to cover.
- Control and cover come together. Harbor’s pitch is that an insurer that pays for losses has a reason to make sure the controls actually work.
- Many details are still missing. Harbor has not said who its customers are, what its policies cost or what capital stands behind its insurance.
