Back in 2015, when Mike Salguero set out to buy some grass-fed beef for himself and his wife, he had to meet a farmer in a parking lot, who handed him the beef in a trash bag. Naturally, Mike figured there had to be a better way. At the time, he was running a company that was slowly cratering, and he didn’t know the first thing about sourcing or packaging meat. But he had a hunch that if he c...

Artificial Intelligence was once the realm of science fiction. But over the last several years, advances in machine learning and deep neural networks have moved us closer to a reality where computers can learn and solve problems independently, the way a human does. From art and music to medicine and politics, the potential applications of AI are nearly endless, and the technology just keeps gettin...

When you consider the risk of doing business, it doesn’t get much bigger than starting a car company: competition is formidable, startup costs are in the billions, and very few people believe you can pull it off. That’s the massive challenge RJ Scaringe walked into in 2009, when he launched his truck and SUV company, Rivian. To add to the risk, RJ wanted to build fully electric vehicles while attr...

Just six years after launch, S'well reportedly made $100 milli...

In 2014, friends Polina Veksler and Alex Waldman went clothes shopping at a major department store. To Polina’s surprise, Alex’s options were quite limited, and tucked away in one of the store’s less-traveled upper levels: the ‘plus-size’ section.  This unnerving realization that women could have such completely different shopping experiences at the same store drove Polina into research mode....
