Lyft co-founder John Zimmer returns to The Advice Line to guide three founders through scaling challenges. From a UK showerhead innovator expanding to America to a weighted vest bootstrapper financing inventory, and a craft chocolate maker balancing purpose with personal sustainability, Zimmer shares lessons from building a rideshare giant. His advice centers on testing assumptions before scaling, creative financing over waiting for capital, and protecting your health to serve your mission. The episode offers a masterclass in founder resilience from someone who's lived the startup journey.
