How two guys made an app in 8 weeks?

Learned to code at night after work. (Kevin)

Built an HTML5 prototype called Burbn.

Gave it to friends to use.

Met investors at a party, showed them Burbn.

Took the jump and quit his job.

Got $500,000 in funding.

Found the co-founder, He was Mike.

Looked at what they had an app that did everything from check-ins to photos.

Decided to focus on one thing- Photos.

Prototyped a photo sharing app from scratch.

Built a pretty awful photo app.

Went back to the old version (Burbn).

Made Burbn into an iPhone app, but it felt cluttered.

Threw out everything, only left photos.

Renamed the app to Instagram.

Launched on a Monday.

In few hours became #1 photo app.
