We found this morning this brilliant presentation given by Instagram co-founder Mike Krieger loaded up to Scribd. It takes you into the wildly successful launch and rise of Facebook’s newest prized toy, photo-sharing app Instagram. As all start-up stories, it was a bumpy ride.

Amazingly, Instagram pulled in 25,000 sign-ups on day 1 of launch, “the best and worst day” of Krieger’s life. It set in motion a frantic scale-on-the-fly scenario which, in hindsight, produced this gem of an observation: “scaling = replacing all components of a car while driving it at 100 mph.” Love that analogy!

There is a lot of back-end speak in the beginning, but plenty of interesting take-aways too, including these lessons that spell out the Instagram philosophy:

1) Simplicity

2) Optimize for minimal operation burden

3)  Instrument everything

What exactly does that mean? Check out the presentation for more:
