Casap is an AI-native platform that automates the entire payment dispute and fraud-operations lifecycle for banks, credit unions, and fintechs. Its agentic AI handles disputes from intake to chargeback, scores first-party fraud, and keeps institutions compliant with Reg-E, Reg-Z, NACHA, and card-network rules. Founded in 2022 by former Robinhood and Chime product leaders, Casap reports a 51% reduction in fraud losses, a 97% chargeback win rate, and 3x faster resolution, and raised a $25M Series A in 2025 to reach $33.5M in total funding.
Shanthi Shanmugam is the co-founder and CEO of Casap, a New York fintech that uses AI to automate payment disputes, chargebacks, and first-party fraud detection for banks, credit unions, and fintechs. A UC Berkeley electrical engineering and computer science graduate, she cut her teeth as a product manager at Facebook and spent roughly five years at Robinhood, where she launched the first crypto trading feature and later ran customer-care products. Watching back-office breakdowns erode consumer trust convinced her the dispute process was broken, so she reconnected with a former Facebook colleague, Saisi Peter, and started Casap in 2023. In August 2025 the company raised a $25M Series A led by Emergence Capital, bringing total funding to $33.5M.
