# Financial AI Startup Casap Raises $56 Million to Combat Fraud Casap secures funding to help banks resolve rising first-party credit card fraud disputes. - **Source:** [Fortune](https://fortune.com) - **Published:** 2026-10-28 - **Topic:** [Finance](https://brifing.si/c/finance) - **Original article:** - **On Brifing:** https://brifing.si/s/4b46ffd6-f2ad-4300-920d-082fcd1b2804 ## Shift in Fraud Landscape Credit card fraud is evolving as cardholders increasingly commit first-party fraud. Nearly one-third of fraudulent transactions now originate from the cardholders themselves, often influenced by social media tips and AI tools. This shift challenges traditional security models that were primarily designed to detect external bad actors rather than dishonest customers. ## Strategic Funding Milestone Casap recently announced a $56 million Series B funding round led by Base10 Partners. This investment brings the startup's total funding to $90 million since its 2023 launch. Strategic investors Synchrony and Experian also joined this round, signaling strong institutional interest in automated solutions for managing complex financial dispute processes. ## Regulatory Burden on Banks Existing consumer protection laws prioritize shielding individuals from third-party fraud, placing a heavy operational burden on banks. Financial institutions often struggle to reject dishonest claims due to rigid regulations that assume customer honesty. Consequently, many banks automatically approve disputes below certain thresholds to avoid the high costs of manual investigations. ## AI-Powered Dispute Resolution Casap utilizes a specialized AI harness trained on large models to streamline dispute resolutions. By analyzing physical card locations and spending patterns, the system identifies potential dishonesty in claims. This technology allows banks to move beyond simple threshold-based approvals, enabling more rigorous verification of customer claims while maintaining operational efficiency for issuers. ## Measurable Operational Impact The startup reports that its clients have reduced first-party fraud losses by up to 51%. Furthermore, Casap users have achieved a 96% chargeback win rate, significantly outperforming the 60% industry average. These metrics demonstrate the effectiveness of automated tools in reclaiming lost revenue and improving the overall financial health of card issuers. ## Efficiency Gains in Processing Casap reduces the average dispute resolution time from 90 days to just 8 days. While human reviewers remain in the loop, the AI streamlines their tasks, often requiring only one to two minutes per case. This drastic reduction in processing time lowers administrative costs and improves the speed of financial operations. ## Leadership and Expertise CEO Shanthi Shanmugam co-founded Casap with Saisi Peters, a veteran of Chime. Shanmugam brings extensive product management experience from major Silicon Valley firms including Robinhood, Meta, and Salesforce. This background informs the startup's focus on building scalable, user-centric AI solutions that address the specific back-office pain points currently facing financial institutions. ## Future Expansion Plans Following this funding round, Casap intends to expand its services into adjacent back-office functions. The company plans to apply its dispute resolution expertise to customer complaints and collections services. By broadening its product suite, Casap aims to become a comprehensive partner for banks and credit card companies seeking to automate operations. ## Sources covering this story - https://fortune.com/2026/10/28/dd/ — --- _Summary written by Brifing from the original reporting.
