Overwatch Data raises $15 million to help firms fight AI-powered hackers

Overwatch Data, a company that uses AI to track cyber criminals, has closed a $15 million Series A funding round. Mouro Capital led it. Visa Ventures and Capital One Ventures also put money in. The pitch is simple: attackers now use AI to move faster, and many security and fraud teams are still working by hand.

What changed

Overwatch Data says AI has made attacks cheaper, quicker and more frequent. It also says cyber, fraud and customer onboarding teams often work in separate silos. Each team sees only part of what the same attacker is doing. The company cites FBI figures putting US cybercrime losses at $20.9 billion in 2025, up 26% from the year before.

How it works

The company's software uses AI agents, which are programs that carry out tasks on their own. They collect warning signs from many places, drop the irrelevant data and link patterns across sources. Then they take an investigation as far as a suggested decision, with the evidence a human analyst needs to check it.

Each confirmed investigation goes into a shared knowledge base. The company says this means the system improves as more customers use it.

The numbers

• Round size: $15 million Series A, led by Mouro Capital.
• Other backers: Visa Ventures, Capital One Ventures, PruVen Capital and New Era Capital Partners.
• One regional bank client found six times as many critical threats, more quickly, according to the company.
• That bank also saved each analyst over 20 hours a week of manual sorting, the company says.
• Visa is a current customer.

Where the money goes

Overwatch Data plans to extend its agents into more stages of risk work. That includes ongoing monitoring, investigations into criminal underground activity, merchant onboarding and due diligence. It is also hiring in engineering, investigations and sales. Last year it hired Jeff Needham, formerly chief revenue officer at Flashpoint and Intel 471, to lead its go-to-market work.

What is not known

The results come from the company, not an independent test. The material does not name the bank, say how the results were measured, or give pricing, customer counts or the company's valuation. For business owners, the practical question is whether your fraud and security checks share what they learn, or whether each one sees only a slice.
