Prajit Nanu

Prajit Nanu is the co-founder and CEO of Nium, the Singapore-born fintech unicorn that has quietly become the plumbing behind global money movement for banks, airlines, and digital platforms. Starting with a frustrating attempt to wire INR 40,000 for a friend's bachelor party in Phuket, he built what is now a $1.4 billion payments infrastructure company processing over $8 billion annually across 190+ countries in 100 currencies. A commerce graduate from Mumbai with a sales background rather than a fintech pedigree, Nanu turned that outsider status into competitive advantage - building what incumbents told him was impossible.

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.

With nearly 25 years in venture capital, he backed PayPal as one of its first institutional investors, led Series A investments in Kabbage (acquired by American Express), Coupa Software (NASDAQ: COUP), and Waze (acquired by Google for $1.15B), and championed the thesis that real-time data would reshape lending, payments, and enterprise procurement. His four-factor investment framework - team, market, technology, and whether the company actually matters - reflects a philosophy that has made him one of Silicon Valley's most recognizable early-stage fintech investors.

Eli Chait

Eli Chait is the Co-Founder and CEO of Wholesail, a San Francisco-based B2B payment risk management platform modernizing accounts receivable for food and beverage distributors. His origin story is unusually grounded: at age 12, he was entering invoices for his father's restaurant in Los Angeles. That early hands-on encounter with the pain of paper-based B2B trade became the north star for his entire career - from co-founding Copilot (a restaurant analytics startup acquired by OpenTable) to leading Wholesail through a $22.6M Series A. With a team of repeat entrepreneurs forged at OpenTable, Wholesail is building the credit and payments network for the $1+ trillion US food distribution market.
