Will Messina
Will Messina is the co-founder and CEO of GrailPay, a New York-based fintech building the risk and intelligence layer for bank payments. He started the company as a broke college kid at Boston College who wanted people to pay straight from their bank accounts, then pivoted from a consumer idea into the unglamorous plumbing of ACH: fraud detection, account verification, and settlement certainty. In June 2026 GrailPay raised a $10.5M Series A led by MissionOG to scale its Payments Identity Network, which covers over 99% of US bank accounts and aims to become the trust layer for instant and agentic B2B payments.
Darragh Buckley
Darragh Buckley is the founder and CEO of Increase, an enterprise-grade banking API company that lets technology businesses programmatically store, move, and reconcile money by connecting directly into the Federal Reserve's payment rails. He was Stripe's first employee, joining the Collison brothers - fellow natives of Limerick, Ireland - in 2010 to build the banking and money-movement foundations of the company. After leaving Stripe in 2016, he founded Increase (YC Summer 2020), which now processes well over $100 billion a year with a famously tiny team. A contrarian who believes in the staying power of community banks, he has personally acquired stakes in small Washington-state banks, including a 10%-plus position in Twin City Bank that triggered Federal Reserve disclosure.
