Prior to founding Keyto, Ray was the founder of Weilos, a social weight loss startup that was acquired by Weight Watchers in 2015. Weilos was renamed WW Connect which powers social networking in the Weight Watchers app, and serves as the digital alternative to in-person meetings to inspire millions of people around the world today.

Before Weilos, Ray graduated with honors from the MD/MBA program at Cornell, and was a consultant at McKinsey & Company where he focused on healthcare.

Liane was Chief Engineer on WW Connect, an online community for weight loss support. Emboldened by the amazing, positive remarks she received there, she wants to continue her journey to help others be their best selves. In addition to being a Co-Founder of Keyto, she also leads Engineering and Product Development. Liane is looking forward to releasing a Keyto experience that is easier, better, and more fulfilling than any other ketosis solution before it!

Gareth Everard comes to Keyto after success in creating multiple seven-figure consumer brands. He thrives as a Co-Founder that brings people the products they don’t just want, but need. As a leader in User Success and Product Development, he is our go-to guy for ensuring that Keyto, the experience, is as polished as Keyto the device. Gareth is currently leading the charge of the Keyto end-user experience.
