Hackathons are blowing up in London (and beyond). I saw this anecdotally, then the search traffic analytics agreed. It's because AI has done a few things: 1. Made software faster/cheaper to make 2. Broadened the type of person interested in making software 3. Made hosting hackathons easier, because you can do them faster So we're seeing the supply (of hackathons/venues) AND demand (of participants) expanding at the same time. Speaking to some of the young people at hackathons, in Ramen Space and beyond, it's increasingly how smart young people are socialising, learning, finding work, having fun. But with hackathon discovery sites, I kept running into: 1. They're incomplete (e.g. not picking up some called 'buildathons' or 'hack nights') 2. They're a bit bloated, clunky or unfocused 3. I wasn't feeling the vibes UX wise So on Saturday I hacked together londonhackathons.com to help me keep on top of them. Complete with: 1. Thorough, expansive hackathon discovery for the next 90 days 2. Weekly newsletter to stay on top of stuff 3. Nothing else yet, let me know what you want 🤩
