#32 $4M ARR in 8 Months: The Subscription Pivot That Worked | Sam Shames

Episode notes

This time, I’m joined by Sam Shames, the co-founder and COO of Embr Labs, an MIT-born startup that’s creating a whole new category of wearable tech—personal temperature regulation. Sam’s journey is a masterclass in building hardware startups that survive, scale, and serve a deeply underserved audience. We talk about: Inventing a wearable that heats and cools ‍ Solving real pain for the thermally underserved (think menopause, MS, dysautonomia) What 4 years of R&D before Kickstarter taught them A subscription model that unlocked $4M ARR in 8 months What most hardware founders get wrong about manufacturing This episode is packed with real, tactical insights on building category-defining hardware, finding PMF, staying alive when others fold, and navigating the messy middle of hardware + subscription + software.
