Register for the event
Agenda:
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.

The people

These open and free events are hosted across cities and countries as part of a broader effort to keep the startup ecosystem accessible, inclusive, and connected. You’ll find a diverse mix of participants: early-stage founders, students, aspiring entrepreneurs, professionals exploring transitions, and others curious about the theme. Each event brings a different experience, shaped by the people who show up.

The format

We host panels, talks, socials, open houses, and demo days in different formats. Each individual event listing clearly mentions what’s planned, so you know exactly what kind of experience to expect before you register.

The flow

You can check the exact time and map address of the venue directly on the event page. Once you register, you typically receive four emails: a confirmation, a reminder a day before the event, another on the day itself, and a follow-up after it ends. You can manage your email notifications at any time.

The guest list

The participant list on the event page keeps updating as more people register. Since attendees often sign up through platforms like eChai, Meetup, Eventbrite, and others, the visible numbers may not reflect the complete turnout. Speakers are usually announced three to four days before the event, and you’ll also start seeing featured participants appear as they register.

The context

You can also explore the list of past participants and speakers from each city to get a sense of who typically joins. It offers a glimpse into the kind of conversations, collaborations, and diversity that shape each meetup. Every event has its own purpose, shaped by its theme, setting, and the community that gathers around it.

The experience

Some people come to learn, others to connect, and many just to explore. While the agenda provides structure, the real energy often comes from the spontaneous conversations and shared curiosity in the room. These events are open to a broad mix of people including students, professionals, early-stage founders, and aspiring entrepreneurs. If you are specifically looking to meet only growth-stage or highly targeted founders, this may not be the right format for you. In that case, you might explore scale up dinners and socials for growth stage founders and operators.

The eChai Effect - In Their Words

"eChai has played a truly pivotal role in HummingBird’s journey — even before Day Zero. From ideation to establishment and into growth, it’s been a constant source of support. It connected me with incredible people who’ve become more than just friends. One of the biggest reasons I chose to stay in Ahmedabad is because of the eChai community. It has shaped my growth — both personally and professionally — in ways that are hard to articulate. Honestly, words fall short when I try to express what eChai means to me. I’m deeply thankful and forever grateful to eChai for being such an integral part of my journey."

“I have no hesitation in saying that my association with eChai has been a gateway into the startup ecosystem. Through this platform, I’ve had the opportunity to connect with many young and dynamic entrepreneurs. These interactions have been immensely enriching - I’ve learned a great deal and have always tried to offer guidance whenever approached. It’s a truly symbiotic relationship that I deeply value, and it wouldn’t have been possible without eChai.”
