Jack Altman on Product-Market Fit

Jack Altman joins Speedrun to discuss product-market fit, customer feedback, hiring, fundraising, and the realities of building an enduring company. Drawing on his experience building Lattice from startup to multi-billion-dollar company, Altman explains how founders should think about customer requests, when to pivot, and why some of the hardest decisions come from balancing conviction with market feedback. He shares lessons from the early days of Lattice, including finding product-market fit, building a sales motion, hiring the first employees, and navigating the tradeoffs that emerge as companies scale. The conversation also covers fundraising, co-founder relationships, startup momentum, and what Altman looks for today as an investor at Alt Capital.
