Brandon Millman and the Trouble With Crypto's Front Door
A former Twitter and 0x engineer saw that crypto's first screen was often its hardest. With Phantom, he turned a wallet into an argument about how ordinary people should enter a complicated world.
Francesco Agosti Is Making the Wallet Disappear
The Phantom co-founder has spent a decade turning complicated systems into ordinary software. His hardest trick is making crypto feel less like crypto - without taking control away from the user.
Star Xu Built an Exchange. Now He Wants the Exchange to Disappear.
The physicist-turned-founder spent a decade building one of crypto's large centralized exchanges. His next wager is a peculiar one: that trust will come from stronger rules, better machinery and giving customers less reason to leave their assets with him.
Riad Wahby
Riad Wahby is the co-founder and CEO of Cubist, a key management infrastructure company building hardware-backed, policy-driven signing for Web3. He is also an assistant professor of Electrical and Computer Engineering at Carnegie Mellon University and an applied cryptographer known for co-inventing the proof systems Lasso, Hyrax, and Brakedown and co-authoring the BLS signature standard (RFC 9380) used across Ethereum, Avalanche, and other chains. Before academia and entrepreneurship he spent a decade designing analog and mixed-signal chips at Silicon Labs and researched cryptography at Algorand.
Paul Puey
Paul Puey is the CEO and co-founder of Edge, a San Diego-based self-custody crypto wallet and security platform. A UC Berkeley electrical engineering and computer science graduate who once shipped 3D graphics at Nvidia, he caught the Bitcoin bug in 2013 and launched Airbitz in 2014, rebranding it to Edge in 2017 as crypto moved beyond Bitcoin. His pitch is stubbornly simple: if you do not hold your keys, you do not own your coins, and security belongs on the edges of the network, in your hands, not on someone else's server.
Alexander Leishman
Alexander Leishman is the Founder, CEO, and CTO of River, a Bitcoin-only financial institution built to provide brokerage, custody, and mining services to individuals and institutions. With a background spanning aerospace engineering at the University of Maryland, computer science at Stanford, and security engineering at Airbnb, Leishman co-founded River in 2019 after stints at MaiCoin, Deloitte, and Polychain Capital. River has raised over $17.7 million in venture funding and became the first Bitcoin-only exchange to publicly release its financial statements in April 2025.
