Hatch
Hatch is a Menlo Park sleep-technology company that designs bedside devices and a companion content subscription to help people fall asleep and wake up better. Founded in 2014 by former BabyCenter executives Ann Crady Weiss and Dave Weiss, it started with connected products for babies and toddlers (Hatch Rest) before expanding to adults with the Hatch Restore line of sunrise alarm clocks and sound machines. The company pairs hardware with the Hatch Sleep app and the paid Hatch+ library of sleep sounds, sleep stories, meditations and light-based wind-down routines, reaching more than half a million families.
Andrew Herr
Andrew Herr is the founder and CEO of Flykitt (and its parent company Fount), a health and human-performance company that builds systems to eliminate jet lag by targeting circadian disruption and travel-induced inflammation. Before entrepreneurship, he spent over a decade advising the U.S. military on human performance and biotech strategy from the Pentagon's Office of Net Assessment, working with Navy SEALs and fighter pilots. Holding three Georgetown master's degrees and twice named an Army 'Mad Scientist,' Herr has turned the performance secrets of special operators into products trusted by pro sports teams, executives, and everyday travelers.
Jeff Kahn
Jeff Kahn is the co-founder and CEO of Rise Science, the company behind the RISE energy-management app. A Northwestern-trained engineer who turned his own student exhaustion into a research program, Kahn co-published early work on how technology can improve sleep behavior and ran what the company calls the largest study of sleep's impact on real-world job performance across the NFL and Fortune 500 sales teams. He and co-founder Leon Sasson were named to the Forbes 30 Under 30 list, and RISE has surpassed 1 million downloads.
Flykitt
Flykitt is a personalized jet lag prevention system built by Fount, a Los Angeles human-performance company founded by former Pentagon researcher Andrew Herr. It pairs a course of timed supplements, blue-light-blocking glasses, and an AI-powered app that schedules exactly when a traveler should take each pill, wear the glasses, eat, and sleep based on their specific flight. Born from work optimizing Navy SEALs and fighter pilots, Flykitt treats jet lag as a combination of circadian disruption and flight-induced inflammation, and claims the majority of users report minimal to no jet lag.
Rise Science
Rise Science is a Chicago-based health technology company behind RISE, a sleep and energy tracking app built on two ideas sleep researchers agree on: sleep debt and circadian rhythm. Rather than scoring your sleep with a vague number, RISE predicts your daily energy peaks and dips and tells you the best time to do everything - from your last coffee to winding down for bed. Founded in 2015 by Northwestern engineers Jeff Kahn and Leon Sasson, the company has raised $15.5M and grown the app past 5 million users.
Anjan Katta
Anjan Katta is the founder and CEO of Daylight Computer Co., a San Francisco-based public benefit corporation building the world's first blue-light-free, high-refresh-rate tablet designed for human health and deep focus. His flagship product, the DC-1, uses proprietary 'Live Paper' reflective LCD technology - patented by Katta himself - to eliminate flicker, reduce eye strain, and strip away the dopamine-exploiting design patterns baked into conventional screens. A Stanford-educated engineer who started the company in 2018 after years of frustration with how screens were affecting human attention and wellbeing, Katta has raised $20 million from tech veterans and sold out every Founder's Edition batch of the DC-1.
