The Idea:

Matthew Buchanan and Karl von Randow met working at a web design company in Auckland. In 2001, they started their own studio, Cactuslab. Client projects paid the bills, but eventually the pair built something for themselves: a home for people who loved films.

The idea was simple. Keep a diary of what you watch, rate it, make lists and follow other people’s recommendations. A film collection you could share without lending anyone your DVDs.

They explained it as “Goodreads for movies”. Behind that familiar pitch was a useful combination: something you could use on your own, with more reasons to return as other film fans joined.

In late 2011, Matthew showed the early version at a web conference in Brooklyn. The beta attracted enthusiastic users. Hollywood could wait. First, they had to keep paying for it.

This was the beginning of Letterboxd.

The Execution:

The lesson?

Letterboxd gave film fans something useful to do before asking them to build a community: record what they watched. Each diary entry made the product more personal, while other people’s reviews and lists made it more interesting. For founders building around a niche, that’s a useful starting point. Give someone a reason to use the product alone, then a reason to bring their friends.

And find a way to fund the slow bit. This one took years before the blockbuster numbers arrived.
