A Peek Under the Hood at Uber

Once upon a New Year's Eve, after StumbleUpon founder and CEO Garrett Camp dropped $800 on three cab rides, he decided there had to be a better way to get a ride when you really needed one.

He started Uber, a marketplace that connects you via an iPhone or android app with your own private driver. That may sound simple enough but take a peek under the hood, and it turns out be one gigantic math problem, says Ryan Graves, Uber's VP of Operations.

"A lot goes into matching drivers with riders," he told me, "and we measure everything. After someone opens the app, how often do they refresh the screen? How fast does the driver respond? How accurate is his ETA?"

Using GPS, Uber's system identifies the closest on-duty driver to where the rider's location. The driver has 15 seconds to respond. "Drivers love it," says Graves, "because it means less time with an empty backseat. When they're empty they are treating the Uber app like it's hot."

SoMA-Based Formspring Thrives on Curiosity

The San Francisco Bay Area may be the global center of technology entrepreneurism, but not every big idea originates here, of course, although most do seem to find their way here sooner or later.

That's the case with, the social network that helps people find out more about each other and themselves by asking and answering questions.

During the past few funding cycles, Taggar told 7x7 that he has noticed a definite pattern.

Inkling Reinvents Textbooks as Interactive, Multimedia Learning Tools on the Tablet

When it comes to a legacy technology that badly needs to be disrupted, it's hard to imagine a better example than the college textbook.

It's big, heavy, expensive (often over $200), and  -- as Matt MacInnis, CEO of the disruptive digital textbook company, Inkling, jokes -- "It's out of date before it even gets to the printer."

Students have to lug these anachronisms around in backpacks, only to read a chapter here and there as assigned by their professors. New editions appear every two or three years, rendering the older editions essentially worthless.

Second-hand bookstores do a thriving business on campuses as students try to stay within their budgets. Book-sharing, renting, and lending as well as illegal copying all occur as well.

A professor trying to teach from a core textbook in many subjects often finds it resembles the Winchester Mystery House, with chapters added on willy-nilly to a structure that originated many editions in the past, often decades ago.
