A Harvard-trained statistician and former QuantCo, McKinsey, and Bosch alum, he started Taktile in 2020 with fellow Harvard classmate Maximilian Eber after they repeatedly rebuilt the same decision infrastructure for enterprise clients.

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.
