How To Scale A $1 Billion Startup: A Guide From Instagram Co-Founder Mike Krieger. Instagram’s co-founders Kevin Systrom and Mike Krieger have been noticeably silent since their photo-sharing app Instagram was bought by Facebook earlier this week for $1 billion. In the meantime there has been a lot written about that deal, from praise to backlash, parsing what it means and why. But if you’d like to hear a little (actually, a lot) about how Instagram got to where it did, read on. Last night, Krieger gave a presentation at an Airbnb event for employees and members of the network, part of a regular series called the Tech Talk. The subject was “Scaling Instagram.” Considering his company was just bought for $1 billion, it’s a pretty remarkable effort, 185 slides in all.

The talk, as the name of the event would suggest, is mainly about engineering and back-end work. It goes through some of the obstacles and solutions that Krieger and team faced as Instagram instantly picked up millions of users. The full slide deck is here: At Y Combinator’s Biggest Demo Day Yet, Mobile Is Taking Over. There are plenty of observations to be made about Y Combinator’s Demo Day. It’s the biggest ever, with 66 companies in this Winter class.

It’s more diverse than past years, with many companies being led by women and people of color. And the audience, packed in at the Computer History Museum, is about as high-quality as you get at these sorts of things. It’s full of Silicon Valley elite, plus other investors and executives who have flown in from around the country and the world. But the thing that is sticking out the most is the nature of the products being launched. This shouldn’t be surprising, I suppose. Still, Y Combinator began in 2005, before smartphones were mainstream. The shift so visible today has been building over the last couple of years; before, there were only a few outliers, like recently-acquired location company Loopt. The companies today are also noticeably practical — these are not just games and simple utilities. Our coverage today: Ark - Search for people.

The Seven Most Interesting Startups At 500 Startups Demo Day. Halfway to living up to its moniker with over 250 startups, 500 Startups held a series of demo days this week and last, where a group of 33 scrappy startups presented their wares to investors in both New York and San Francisco. As we are wont to do with these things, we visited the 500 Startups offices in Mountain View and interviewed the seven that we thought were the most interesting, from both an investor and consumer standpoint. The startups chosen spanned all sorts of market territory, from a novel take on media-based eCommerce to a SaaS for farmers, but what they all had in common was a unique approach to the problem they were trying to solve as well as an inkling of that other indeterminate thing that makes a startup great. Also, I’m pretty sure Switchcam, a startup that allows for a combining of different camera angles on video, should be on here. 72Lux Ever wish that you could buy whatever product/outfit/gadget/whatever as you were reading about it online.
