Hello and welcome back to a new episode of the "From 0 to 100M" podcast!
In this episode, we dive into the journey behind Duet—exploring how James' personal history, including the influence of his grandmother’s stories, shaped his path into the complex world of NEMT.
We unpack what it takes to build in a fragmented industry across 25+ states, from early challenges in finding providers to the lessons learned by working side-by-side with dispatchers and staying deeply connected to day-to-day operations.
The conversation covers the story behind the product, the realities of scaling, and the importance of honesty, trust, and delivering on promises in client relationships. We also explore how Duet is approaching AI, navigating fundraising, and making tough business decisions while staying focused on meaningful metrics and long-term impact.
Plus, hear the behind-the-scenes story of their first tradeshow, what’s resonating most with customers today, and what’s next for the company as it continues to grow.
