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.

Open Mic Pitching and Networking
Fox@ExCel, Warehouse K, Hotel ibis London Excel Docklands, Excel Centre, 2 Western Gateway, London E16 1DR, London, GBWhere Big Ideas Meet Bold Energy
London’s most electric founder night is back — and if you’ve been, you already know the vibe.
Rare Founders is hosting a special Open Mic Pitching & Networking Night straight after The Business Show — one of the UK’s largest free events for entrepreneurs, investors, and business leaders, happening on 12–13 November.Our very own Vasily will be speaking on stage on the 12th, and what better way to round off the day than bringing everyone together for a drink, some real talk, and a few unforgettable pitches?
Whether you’ve been exploring The Business Show all day or you’re just joining us for the evening, this is your chance to connect, unwind, and meet new global friends in the UK startup community.***
💡 Register for your free Business Show tickets through our partnered link click here, and make sure to stick around for the Rare Founders Open Mic — trust us, you won’t want to miss it.
***
Here’s how it works:
🎯 Every 20–30 minutes, 5–6 founders are randomly picked to pitch their startup in 1 minute. 💦 Go over the time limit? Our water guns are ready. (Yes, seriously.) 🤝 In between, the room lights up with conversations, deals, and serendipitous connections.
This isn’t a stiff, suit-and-tie kind of night. This is raw, real, and ridiculously fun, a space where ideas take flight, and founders find their tribe.
The venue is the hottest spot to be after The Business Show — while we’ll have our own private space for the Open Mic, you’ll also be able to roam the bar and mingle with over 700 other guests between sessions.***
