Sam Shames is the Co-Founder and Chief Revenue Officer of Embr Labs, the company behind the Embr Wave: a wristband that heats and cools to help people manage comfort, sleep, stress, and hot flashes.

What started as a project in an MIT prototyping competition turned into a 12-year journey building a hardware company from scratch. Along the way, Sam and his co-founders grew Embr Labs to 200,000+ units sold, $50M+ in lifetime revenue, and $66M in venture funding. A $100K Kickstarter goal became $630K in sales, powered by a loyal community they engaged long before launch.

Sam’s path blends technical innovation with customer-driven growth. From proving the science behind their product, to surviving on $2K a month while raising capital, to pivoting into a hardware subscription model, he’s learned what it really takes to scale an ecommerce hardware brand.

Whether you’re building a DTC product, validating a new idea, or evolving your business model to better serve customers, Sam offers an unfiltered look at the grind, the pivots, and the lessons behind turning a student prototype into a category-defining company.
