Nebia — which was initially backed by Apple CEO Tim Cook and former Google CEO Eric Schmidt — announced its new Nebia Spa Shower 2.0 on Tuesday. The latest version can create 29% warmer temperatures and comes at a more affordable price than the original. Cook and Schmidt re-invested in the shower head disrupters, along with North America's largest shower head company Moen, Airbnb co-founder Joe Gebbia, Starwood Hotel founder Barry Sternlicht. Nebia CEO Phillip Winter tells us that the Apple chief exec has been "incredibly supportive" with their efforts, answering email questions when they "have something that's very strategic."
