What we’re about
Rare Founders is one of the largest startup communities in the UK with almost 20,000 members.
We run monthly open mic pitching and networking events where founders (mostly pre-seed to Series A) get 1 minute on stage to pitch. If they go over the limit… we spray them with water guns. Our events often feel like catching up with friends, and about 30% of people come on a regular basis.
We’re also known for hosting London’s Largest Demo Day – a one-day conference with 1,500 attendees where 100 pre-selected startups pitch to a full audience of investors.
On top of that, we run masterclasses on everything business-related: pitching, fundraising, go-to-market strategy, legal docs… you name it. We also send out a weekly newsletter with the best startup events in London.
Join us – we’re all about good vibes, fun, low-key energy, and efficiency. We’re different. Come and see for yourself.
