Wellsphere Founder is Back with Stealth-Mode HealthTap

By Connie Loizos — 5 years ago

Plenty of online wellness sites like publicly traded WebMD can answer general questions, including about the symptoms of diabetes. If, say, you need to find more specific information, like where to buy an insulin pump for your teenager in Palo Alto, you can try sites like Sequoia Capital-backed HealthCentral, which drill a bit deeper.

Yet both are still part of “Health 1.0 and 2.0,” according to Ron Gutman, co-founder and CEO of Wellsphere, a health-focused informational and community site that was acquired by HealthCentral in early 2009 for an undisclosed amount. (Gutman says the purchase price was “a good sale” for Gemini Israel Funds and individual investors, who capitalized the company with $3 million in 2007.)

Gutman says that it’s about time to usher in “Health 3.0,” and that he’s doing exactly that with three-month-old HealthTap, which aims to help users and their doctors make better decisions about users’ well-being by relying on their personal data.

Esther Dyson Enters Full-Time Cosmonaut Training, Just in Case

By Connie Loizos — 7 years ago

You’d be crazy to call Esther Dyson a space cadet, right? Dyson’s cred as technology prognosticator and influencer is about as solid as it gets, thanks to a decades-long career as a prolific angel investor, writer, and until 2006, organizer of PC Forum, the gold standard in tech conferences for more than 20 years.

Yet a space cadet Dyson will be if certain stars align. The space enthusiast is spending the next six months in a $3 million cosmonaut training program at a center near Moscow, where she is being instructed as back-up for billionaire Charles Simonyi.
