In this episode of PMFers, we sit down with Griff Green—Giveth founder, early Ethereum advocate, and longtime public goods champion. Griff shares his journey from the early days of The DAO (and its infamous unwind) to building Unicorn, Pairwise, and other experiments in the “Giveth Galaxy.”

We get into what real product-market fit looks like for mission-driven tools, how building for others beats building for yourself, and why relying on grants can quietly kill good ideas. Griff also shares insights from the Orange DAO accelerator, how AI is shifting the dev workflow, and why trust is his superpower. If you’re navigating the gap between impact and sustainability, this one’s packed with hard-won wisdom.

In this episode of PMFers, we sit down with Jango.eth—creator of Juicebox and one of the most thoughtful protocol designers in the space. From making music websites to building roommate apps, Jango’s path to Ethereum started with art, moved through pain points in banking, and culminated in one of the most flexible funding protocols onchain. We dive into how Juicebox evolved from early experiments like Tiles and SharkDAO to becoming the engine behind ConstitutionDAO and the new revenue-backed RevNets. Jango shares hard-won insights on building slowly, designing for sustainability, and why the best infra disappears into the background. We also explore his new omni-chain system, token mechanics, and why Ethereum just needs to not go down. If you’re into protocol design, tokenized revenue, or want to fund your project without begging a VC, this one’s for you.

In this episode of PMFers, we sit down with Zefram.eth to trace his journey from building iOS apps in middle school to launching onchain products like a decentralized hedge fund DAO in the early DeFi days. He shares hard-earned insights on getting first users, staying focused, validating ideas, and why most successful blockchain apps still revolve around finance. We also dive into AI tools for devs, the long game of onchain gaming, and how the Ethereum ecosystem can better support builders beyond infrastructure.

In this episode, Owocki takes us through his early days hacking PHP, the founding of Gitcoin, and what it actually feels like to chase product-market fit onchain. We talk quadratic funding, moonshot bots, accelerators, regen memes, and how to survive (and ship) when everything’s on fire. • Venture Deals by Brad Feld and Jason Mendelson 👉 https://www.venturedeals.com • Green Pill: How Crypto Can Regenerate the World by Kevin Owocki 👉 https://greenpill.party • Chris Dixon – The Idea Maze 👉 https://cdixon.org/2013/08/04/the-idea-maze • Virgil Griffith – Ethereum is a game-changing technology, literally (Canonical post on Ethereum and coordination games) 👉 https://medium

In this episode of PMFers, Austin sits down with Ameen Soleimani (@ameensol)—a pivotal figure in Ethereum’s evolution and a master of memetic engineering. Ameen has played key roles in projects like SpankChain, MolochDAO, Tornado Cash, and now Privacy Pools. Ameen offers an unfiltered look at the challenges and triumphs of finding product-market fit onchain.

In this episode of PMFers, we’re joined by Martin Köppelmann—co-founder of Gnosis and one of the most consistent voices in the Ethereum space since the early days. From hacking on Bitcoin prediction markets in 2013 to helping launch Safe (formerly Gnosis Safe), CowSwap, Circles, and Gnosis Pay, Martin has been quietly shipping some of the most important infrastructure in crypto—often before the world was ready for it.
