“You can fake a lot in a startup these days, what with Amazon Web Servi...” — Antonio Garcia Martinez Quote

You can fake a lot in a startup these days, what with Amazon Web Services and all sorts of off-the-shelf back-end components that let any even minimally competent duffer set up a Web app that does something. Intelligent planning for growth is rare among early startups, but it's the name of the game at a large, rapidly scaling tech company.

In Cuba, where Wi-Fi is both slow and terrible, you will be an emissary from the future, a hint of the degeneracy to come. You're a full-on mainlining internet junkie with the world's uproar piped into your head 24/7, your emotional landscape terraformed and buffeted by whatever some narcissist just posted on Instagram or some windbag on Twitter.

If you'd come to me in 2012, when the last presidential election was raging and we were cooking up ever more complicated ways to monetize Facebook data, and told me that Russian agents in the Kremlin's employ would be buying Facebook ads to subvert American democracy, I'd have asked where your tin-foil hat was.

In Silicon Valley, where I worked at companies like Facebook and Twitter for the earlier part of this decade, Cuba was generally regarded, when it was regarded at all, as a technological curiosity.

I actually think Facebook made it their business to be close with all of the app developers. They couldn't have done more.

In 2010, the night before we launched 'Instagram v1', my co-founder Kevin and I bet on how many people would download the app its first day in the wild.

Cognitive behavioural therapy is very effective for anxiety-related issues, exercise is great, and you can try meditation and positive thinking apps - I'm a big fan of the Calm app.

From its conception, I wanted Bumble's culture to match its values. If women were taking charge on our app, then they'd be running the show behind the scenes, too.

I started, whenever I got to a city, just getting on Style Seat, which is the most incredible app for any girl who doesn't have 100 stylists at her fingertips. I can see who's well-rated and whose portfolio I like, and then book an appointment all from my phone, which made having bangs a lot easier.
