About Us

The human brain is the most complex object in the universe, yet society has accepted one-size-fits all approaches to cognition. The "solutions" (think coffee, energy drinks, and even a friend's rx) were mediocre at best and frankly, made no sense to us. So, we created Thesis, the world's first customized nootropics company. If you've never heard that word before, it's just a fancy way of saying brain supplements. In five years, most will be taking nootropics on the daily and chances are, they'll be ours.

With an exceptional efficacy rate, the world has taken notice — we've raised over $13M in venture capital, garnered interest from leading neuroscientists and athletes, and established ourselves as the industry's leading brand. Now, we're looking for incredible people to help us share the gift of enhanced cognitive function with the world. If you're looking to be a part of a movement — one that involves both immense self-growth and an ambitious mission to pioneer an industry — we'd love to have you on the team.
