1. The London AI Startup Conference 2026

**Thursday, 3 September 2026** **8:30am–1:30pm** 📍 **Google London, Central Saint Giles**

**Best for:** AI founders, CTOs, investors and startup ecosystem leaders

If you're looking to meet people genuinely building in AI, this is one of the highest-signal events on the September calendar.

The event is deliberately curated rather than open to everyone. Attendance is capped at 100 people, including 65 AI startup founders, 25 VC investors and a small number of ecosystem leaders and stakeholders. The organisers say attendees were selected from more than 2,000 applications.

The programme combines presentations with structured networking and is supported by Google Cloud, Zendesk and Stripe.

**BNC pick:** ⭐⭐⭐⭐⭐

*Important: The event is currently full, but a waitlist is available.*

2. Founders Meetup London

**Tuesday, 8 September 2026** **5:30pm–8:45pm+** 📍 **London - exact address provided after registration**

**Best for:** Founders, investors, operators and people looking for co-founders

This is one of the most directly relevant events for anyone actively building a business.

The evening combines open networking, a tactical founder fireside, community shoutouts and drinks.

One particularly useful feature is the colour-coded networking system:

🔴 **Fundraising / Investors** 🔵 **Co-founders / Hiring** 🟢 **Community / Opportunities**

That gives people a reason to approach each other instead of simply standing around with a drink.

The organisers also provide time for founders to share what they're working on, recent wins and challenges where they could use help.

**BNC pick:** ⭐⭐⭐⭐⭐

3. Daytona AI Builders - London

**Tuesday, 8 September 2026** **6:00pm–8:30pm** 📍 **London - exact address provided after registration**

**Best for:** AI builders, founders, engineers and technical operators

If you're building with AI rather than simply interested in AI, this is one to look at.

The event focuses on AI engineering, agents and infrastructure, followed by an extended networking session.

It's a good example of the type of event we want to highlight here: a specific community, a specific subject and plenty of opportunity for people to actually talk to one another.

**BNC pick:** ⭐⭐⭐⭐⭐

👉 **RSVP:** [Luma – Daytona AI Builders London](https://lu.ma/daytona-ai-builders-london) 🐦 **X:** [@daytonaio](https://x.com/daytonaio)

**Thursday, 10 September 2026** **6:00pm–11:00pm** 📍 **Central London - location provided after registration**

**Best for:** Founders, investors and startup ecosystem leaders

Hosted by the London Venture Capital Network, this is designed around relaxed networking rather than a long conference programme.

The event brings together investors, founders and ecosystem leaders from across the venture capital and startup community.

There is a short spotlight from event partners before the evening moves into networking.

**Wednesday, 16 September 2026** **8:30am–10:30am** 📍 **Hale House, 76 Portland Place, London**

**Best for:** HealthTech founders, investors, clinicians and pharma leaders

This is a more specialist event, but potentially a very high-value room for anyone operating in HealthTech, AI or clinical technology.

The discussion focuses on where AI is genuinely accelerating clinical trials, where the bottlenecks remain, and what pharma partners actually want from AI-native companies.

The format includes breakfast and coffee, a panel, audience Q&A and open networking.

**BNC pick:** ⭐⭐⭐⭐

**Best for:** AI founders, growth marketers, builders and startup operators

This is one of our favourite formats in the entire list.

Why?

Because it's deliberately small.

The event is limited to 40 attendees and uses rotating seating to create more meaningful conversations between founders, growth leaders and operators.

The discussions cover AI, GTM, growth, product, fundraising and startups.

And yes, dinner is included.

**Tuesday, 22 September 2026** **6:00pm–9:00pm** 📍 **Halkin Monument, 10 Lower Thames Street, London**

**Best for:** Business leaders, founders, managers, operators and investors

AI Salon takes a more practical approach to AI.

The event brings together people working across business and technology to discuss what is actually working, what isn't, and how AI is changing the way people work.

There are talks, startup demos and plenty of time for conversations afterwards.

The September event includes speakers and contributors with backgrounds at organisations including Google, Meta, Palantir, Bumble, Citymapper and Deutsche Bank.

**Wednesday, 30 September 2026** **From 5:00pm** 📍 **The City of London - venue announced to attendees**

**Best for:** Founders, investors, advisors, finance professionals and capital providers

If you're more interested in capital, partnerships and serious business relationships than startup meetups, this is one to consider.

The event is built around informal networking rather than panels and presentations.

That makes it particularly useful for people who already have a business and are looking to build relationships across the investment and professional services ecosystem.

How to get more from these events

Going to an event isn't the same as networking effectively.

Before you attend, spend 15 minutes doing this:

1. Find five people

Look at the attendee list, speakers and organisers.

Find five people you genuinely want to meet.

2. Follow them

If they're active on X, follow them before the event.

Don't immediately pitch them.

Just become familiar with what they're working on.

3. Start a conversation

If there's a natural reason to reply to something they've posted, do it.

You don't need to say:

"I'm attending your event. Can we connect?"

Start a real conversation.

4. Meet them in person

Now you aren't walking into the room completely cold.

You've already created a tiny bit of familiarity.

5. Follow up

The event is the beginning of the relationship, not the end of it.

Send the message.

Make the introduction.

Have the second conversation.

That's where networking starts to become valuable.

Events are useful. Relationships are better.

A networking event gives you a room full of people for a few hours.

But the real value comes from what happens afterwards.

The right relationship can lead to:

• A customer
• A partner
• An introduction
• A new hire
• An investor
• A co-founder
• A new opportunity
• Or simply someone who helps you see your business differently

That's why we built BNC - [Business Networking Club](https://www.businessnetworking.club/).

BNC is for founders, business owners and ambitious professionals who want to build better business relationships consistently, not just attend another networking event once a month.

You get access to a community of people building businesses, live sessions, conversations, opportunities and a network you can continue building relationships with long after the event finishes.

Want to build your network beyond one event?
