The major reason why Instagram works is that you can follow anyone out there and start following their photos immediately.

I really value passion for the product above experience.

With Instagram, the focus is on the present tense.

I've always been into taking my photos, cropping them square, putting them through a filter in Photoshop.

Obviously, being the CEO, there are a lot of eyes on what you do and what you post and how you post, and I think one of the challenges of Instagram in general is that, as we get bigger, there are just more voices in the room, more eyes on everyone's accounts.

I’m always in awe of people who are artists in their fields – people who understand that simply by taking ideas and translating them into reality, they’ve created value in the world.

I really appreciate crafts. I like cooking. I love food and drink. I love owning that through Instagram. Although that can be challenging at times because it doesn't fit people's stereotypes of a technical founder.
