About

London brings together founders, operators and investors from across the world, and the mixer creates a simple space to meet the people who shape the city’s startup energy. The focus is on real conversations, meaningful introductions and discovering what others are building in a relaxed setting. ​You will meet early stage founders working on their first product, teams scaling across global markets and people who have contributed to some of London’s most interesting companies. The atmosphere encourages open exchanges, small group discussions and the kind of interactions that often lead to new ideas or collaborations. ​This is a good room for anyone building in London, expanding into the UK, or reconnecting with the local ecosystem. People from fintech, SaaS, AI, consumer, climate and creative tech often join in, making the experience rich in perspectives and stories. ​Entry is free. You only pay for what you order. If you are building, exploring, hiring or curious about the city’s startup scene, you are welcome to join a warm and global group of founders who enjoy meeting fellow builders one conversation at a time. ​.. eChai Ventures - Your Startup’s Global Neighborhood. Startups grow faster when founders are plugged into the right conversations. That’s what eChai makes happen — connecting founders across cities, stages, and markets. Visit: eChai.Ventures

Founders here come to know a few brands well.

Those are eChai’s partner brands. Over a year, founders across the network learn their names and their work, and when somebody asks around for what they do, theirs is the name that comes up.

What a year inside eChai does for your brand.

Each partnership comes with presence across eChai, introductions to the right founders, and a team that stays involved through the year. And each one is shaped around what the brand wants out of it.

Who you meet

  • Founders learn your name, then your work.

    Over the year they keep running into you: at the gatherings, in the series, on the pages they read through the week. So when one of them needs what you do, they come straight to you.

  • We introduce you to the people you want to reach.

    After seventeen years of gatherings we know who has built what, and who works with whom. Tell us who you are after, or we come to you when the right person shows up, with your story and why you two should talk.

  • You are invited to the gatherings that fit.

    Open houses, Demo Days, the AI sessions, FailCode, the curated socials and the smaller dinners, some of them by invitation. When one fits what you do and who you want to meet, you are on the list.

What we do with you

  • We sit down with you on your story, your brand and your business.

    One to one, more than once in the year. We have heard a few thousand founders, so you hear fairly quickly what is working, what is not, and what we would change first.

  • We take your team through what AI changed for us.

    Almost everything eChai builds now has AI in the workflow. We go through what we tried, what worked and what wasted our time, and then connect you to founders further along than us.

  • You can ask us anything, whenever it comes up.

    Every week we hear what founders are building, what they recommend to each other and what they have moved on from. Twice a year we go through what it means for your category. In between we answer, or find a founder who can.

Where your name runs

  • Your mark comes round under every page on eChai.

    The wall of partner brands under the site's pages draws a different ten each time, so yours comes round on the city pages, the event pages and the notes founders read, all year. Your page on echai.ventures stays up after it, and your name runs through our LinkedIn, Instagram and X.

  • The blue tick puts you first wherever founders are listed.

    The tick and your company's mark sit beside your name across eChai, and lists of founders put the blue ticks first: your city's people, the directory, and the roster of every gathering you go to, after its hosts and speakers.

  • Your company carries its mark on the Startup Grid.

    Where your company is on a city's map of its startups, it is drawn by your mark rather than a dot, opens on your own words and pictures, and is a stop on the tour the map offers of its partner brands.

  • You write and speak here under your own name.

    You come into the series we run online (How Founders Use AI, the founder conversations, the long reads) where you have something real to say, and you write in Founder Notes, where founders across our cities write about what they are building.

How it works.

A partnership is for growth stage founders who want to come in as a partner brand, and it runs one year at a time. The brand fee for the year is paid to eChai. An affiliate share runs alongside it, linked to the outcomes we drive together. Both carry GST.

Everything a partnership comes with

To come in as a partner brand, write to me at [email protected] and tell me what you want the year to do for your brand.

Every city on eChai

Founders who came to their first meetup years ago are still turning up, in cities they hadn’t moved to yet.

Joining is a profile: a photograph, your name and a way to reach you. With it, registering for a gathering takes one tap.
