This Q&A podcast episode of "How I Built This Lab" features Kaitlin Smith, founder of Simple Mills, answering listener questions about building a food business. The show begins with an introduction and several advertisements, then proceeds through several listener calls, each focusing on unique challenges in launching and scaling food products. Kaitlin and host Guy Raz offer advice on securing funding, choosing the right products to launch, identifying manufacturing partners, and effective marketing strategies. One key takeaway is the suggestion to start with simpler, more easily scalable products before tackling complex manufacturing processes, as illustrated by the advice given to a listener launching an upcycled pretzel company. The episode concludes with additional advertisements and production credits.
