Casap raises $56M to use AI to settle card disputes faster

A New York company called Casap has raised $56 million to build AI that handles card disputes for banks. Those are the cases that start when you tell your card issuer a charge is wrong. Casap says its software now settles most of them with little human effort, and that cases close in 8 days instead of as long as 90.

What changed

Casap announced on October 28 a Series B, which is a funding round for a company that has already begun to grow. Base10 Partners led it. Credit bureau Experian and card lender Synchrony joined, along with earlier backers Emergence Capital and Lightspeed Venture Partners. Total funding is now $90 million. Casap says its revenue grew 10 times in the year since its $25 million Series A.

How it works

Casap uses AI agents, which are programs that can carry out a task from start to finish instead of just answering questions. These agents investigate a case, make a decision and act on it inside the systems a bank already uses. They follow each bank's own rules. When a call needs human judgment, they hand it to a person.

Casap says every decision comes with evidence and a record of what was done, so a bank can explain and audit the outcome.

The numbers, and who reported them

Every figure below comes from Casap, not from an outside check. The company says it works with more than 100 banks, credit unions, fintechs and payment processors.

• Agents resolve 73% of dispute cases, with people still overseeing.
• Resolution time fell from as long as 90 days to 8 days.
• Human handling time per case fell from 45 minutes to one or two.
• Chargeback win rate is 96%, against a 60% industry average.
• First-party fraud losses fell by up to 51%.

Why first-party fraud matters

First-party fraud is when a customer disputes a purchase that was real, just to get a refund. Casap said in 2025 that this makes up 30% to 50% of total fraud losses. It makes disputes harder for banks to judge, which is part of why honest customers can wait so long.

Who it affects

If you dispute a charge, a bank using this kind of tool may get back to you faster. Synchrony, which serves more than 100 million Americans, backed the round to speed up dispute resolution and stop first-party fraud. The article does not say which banks use Casap or whether your card issuer does.

What happens next

Casap plans to take its platform beyond disputes into fraud, collections, claims and other complex exceptions. Experian is exploring new fraud signals built with Casap's data. Rivals are also raising money, including Quavo, with a $300 million investment from Spectrum Equity in July 2025, and Chargeflow, which raised a $35 million Series A in November 2025.
