Foursquare has been able to raise a whopping $41 million, but the funding hasn't come in the form you might expect.

The company announced the news today, saying the cash came from a host of well-known Silicon Valley investors, including Andreessen Horowitz, Union Square Ventures, and others. However, rather than give those firms equity, Foursquare raised the $41 million through a combination of tapping into the Silver Lake Waterman growth debt fund, as well as asking for convertible debt from the aforementioned investors, among others.

The cash raised helps Foursquare fund its growth and also aids the company in … Read more

They're simple, social, and entirely made for mobile, all of which might explain the explosive growth of standalone messaging apps even as Facebook offers a free way to chat on smartphones.

One of the biggies, Kik says that it now has more than 50 million users and that people -- mostly young people -- are signing up at a rate of 200,000 a day. That's twice the rate that Kik claimed when it last released stats. Just last November, the app claimed 30 million users and said that 100,000 people were signing up each day.

MOUNTAIN VIEW, Calif. -- While hobbyist use of drones is all the rage these days, there are few ways for commercial or enterprise customers to get unmanned aerial vehicles (UAVs) in the air.

But that's what Airware, one of the startups in the winter 2013 Y Combinator class, showed off at Demo Day today.

The Newport Beach, Calif., company aims to give commercial companies an easy-to-use development platform that will get their purpose-built drones up and flying in no time. Airware's platform comprises both on-board hardware and software, founder Jonathan Downey said. It also features elements that all … Read more

When F. Scott Fitzgerald claimed that "there are no second acts in American life," he clearly didn't foresee the resilient career of the man who once headed America Online. Rita Braver reports:

He was the Boy Wonder of computing, co-founding the pioneering Internet service America Online while still in his twenties, and then helping make it the top-earning stock of the 1990s -- trying, he told CBS News back in 1997, "to build an interactive medium to inspire people's lives."

And if you've ever wondered what happened to Steve Case, look no further. … Read more
