Noom

Noom is an American privately held digital health company that delivers weight-management and behavioral-health services through a subscription-based mobile app. Its programs combine behavior-change psychology — drawing on cognitive behavioral therapy (CBT) and goal-setting — with access to weight-loss medications and dietary supplements. Beyond core weight management, Noom has expanded into stress management and general wellness offerings.

The company traces back to WorkSmart Labs, founded in 2007 by Saeju Jeong and Artem Petakov, which rebranded as Noom in 2011. Jeong served as CEO for roughly 16 years before transitioning to Executive Chairman; in a planned leadership change announced in December 2023, Geoff Cook (former co-founder and CEO of The Meet Group) was appointed CEO and joined the board. Petakov serves as co-founder and head of Noom Ventures. Noom is headquartered in Princeton, New Jersey, with early roots in New York City.

Noom has raised on the order of $600–650+ million across multiple rounds, with investors including Silver Lake, Sequoia Capital, and Temasek. Its largest round was a $540 million Series F in May 2021, led by Silver Lake, which valued the company at roughly $3.7 billion. Reported revenue was about $600 million in 2021 (figures may not reflect current private financials).

Reflecting the surge in demand for obesity drugs, Noom launched a 'Microdose GLP-1Rx' program offering low/micro-dose GLP-1 prescriptions (e.g., semaglutide) paired with clinical monitoring and behavioral coaching. Because Noom operates at the intersection of behavioral science, mobile technology, and pharmacological weight loss, innovations in this space are directly relevant to its product direction and competitive positioning.
