Michael Hershfield is the founder and CEO of Accrue, a New York fintech that lets retailers embed FDIC-insured, brand-customized savings wallets inside their shopping experience.

Mine has grown to roughly a million users, about $10M in annual recurring revenue, and raised around $28.5M from Kleiner Perkins, 359 Capital, SV Angel, and Y Combinator.
Ashin Shah is the co-founder and CEO of Made Card, a New York fintech building the first credit card designed for the full homeownership lifecycle.

The Made Essential Visa Signature Preferred Card pays homeowners for on-time mortgage payments and everyday home spending, with points redeemable toward lower closing costs. In November 2025 the company launched with $8M+ in seed funding co-led by Jump Capital and Village Global, plus a nationwide distribution deal with Fairway Home Mortgage.
