Gagan Biyani, Morgan Springer, Neeraj Berry, Matt Kent

Cofounders, Sprig

CEO Gagan Biyani's mission is for Sprig to become "the easiest way to eat healthy in the world." Former Google head chef Nate Keller leads the in-house kitchen staff that prepares each meal delivered by Sprig, the on-demand fresh-food delivery service that launched in November 2013. It offers three meal options daily and aims to deliver the food in 15 minutes.

In April, the company raised $45 million in funding, which spurred its expansion to Chicago from the San Francisco Bay Area.

Conrad Chu, Tri Tran

Cofounders, Munchery

Tri Tran and Conrad Chu wanted to provide the convenience of a professional chef without the high cost, and in 2011 Munchery was born. The company is similar to Seamless, except your food is made by Munchery's chefs instead of being outsourced to restaurants. Each time you order a meal on Munchery, the company makes an equivalent donation to a charity in your town.

Munchery made headlines in April when it raised a $28 million Series B round. More recently, Sherpa Ventures, a prominent venture-capital firm, announced it was making its "biggest bet since Uber" by endorsing Munchery. At the end of May, the company announced its Series C round of $85 million co-led by Menlo Ventures and Sherpa. Munchery has raised $117.2 million, including contributions from celebrities such as Jared Leto and Edward Norton.

Todd McKinnon and Frederic Kerrest

Cofounders, Okta

McKinnon is a Valley A-lister, a former star Salesforce engineer who launched his own company in 2009 without CEO and friend Benioff's blessing. His company has seen massive growth: By September 2014 it had raised $155 million from top VCs. Okta is now valued at about $600 million and is expected to go public by 2016.

McKinnon said there's tremendous value in working for a rapidly growing, successful company before pursuing other endeavors. He called his time at Salesforce a "gift" that taught him what it means to win.
