London tech events this week: Breakpoint takes Olympia, the rest of town keeps building

For five days the biggest tech room in London is a crypto conference. Solana Breakpoint opens at Olympia on Sunday afternoon, and four more of the twenty-two tech events on our London page this week orbit it. The other seventeen carry on as if nothing's happening: agent security in Shoreditch, genomics in White City, a 600-seat AI night in Clerkenwell. Plenty of networking events in London this week, then. Your job is choosing which London you're in.

The Big One: Solana Breakpoint 2026, from Sunday

Solana Breakpoint 2026 - Sun 15 Nov, from 16:00, Olympia London, paid.

Solana's flagship conference, three days at Olympia from Sunday afternoon to Tuesday 17 November. Keynotes, lightning talks, debates, workshops, and the product and protocol announcements the ecosystem saves for this week. The Solana Foundation is selling London on its capital base: family offices, sovereign wealth, hedge funds, private credit, commodity desks. So the floor skews further towards institutions and investors than Breakpoint usually does. The ticket is priced in dollars, so check the conversion before you book.

Buy it if you build on Solana, fund crypto infrastructure, or sell to the people who do. Skip it if you're crypto-curious and want an intro. It's a trade show for an industry that already knows what it thinks.

London tech events, day by day

Friday 13. 200ms - 09:00 to 18:00, address on registration, free but selective. A day on Solana market microstructure with Jito, Anza, Firedancer, Helius and Multicoin Capital among the sponsors.

And the pick of the night: She Bytes Back x Snyk: What Breaks When Agents Start Shipping Your Code? - 18:00 to 21:00, free, approval-only for experienced women engineers. Three talks on code that passes every test and is still wrong.

Thursday 19. The busiest day, six rooms. BSI Trust in AI Conference 2026 runs 09:15 to 17:00 at the Royal Institution, Dame Wendy Hall keynoting. SaaSiest London is £349 at CodeNode with CEO, Revenue, Finance, Product and CS rooms. Evening: Trusting AI at Level39 (£10), Data Engineers London x Vivanti (free, dbt inside Snowflake), the London Life Sciences Week reception at Scale Space White City, and techUK's Defence Winter Dinner 2026, paid, 280-plus delegates.

First-timer's note: apply, wait, bring ID

Seven of this week's rooms hand out the address only after you're approved or registered. Apply the day you decide, not the day before. House of Sol is 18+ with photo ID on the door. Last week's Agentic AI meet-up at Deliveroo wanted photo ID at the door too. If a listing says approval, assume a bouncer with a list.

Who should go where

Investors, Breakpoint is pitched at you. Olympia from Sunday if crypto infrastructure is in your mandate. If it isn't, Monday is the week's dealflow evening: Biology After AI for techbio, or IE x FOMO for the inside story of a fast round. Thursday's life sciences reception does the academic-to-industry pipeline.

Builders, Saturday and Wednesday. Scale or Die if you run Solana infrastructure. Wednesday if you ship agents: She Bytes Back, or DSOLG if you want the post-quantum half too. Data people take Thursday at Vivanti.

Founders, keep it to one evening. Monday at Imperial is an hour and free. SaaSiest is the paid day for B2B SaaS leaders. Skip the Breakpoint fringe unless crypto is your market.

Sales and marketing, Tuesday. GTM Hackathon by Granola x Gemini puts your own meeting notes behind Gemini, with Google DeepMind in the room, curated and free. CRAP Talks is the fallback if you aren't picked.

FAQ corner

Why do so many of these events have no address?

They're approval-gated: 200ms, Scale or Die, Biology After AI, House of Sol, She Bytes Back, the GTM hackathon and the Defence Winter Dinner all send the address once you're accepted. No acceptance, no address.

Is Breakpoint one day or three?

Three. It opens Sunday 15 November at 16:00 and runs to Tuesday 17th. Our listing shows the Sunday session only.

Worth knowing

Solana Intelligence Summit reads sold out at the organiser's end. Our page still shows availability; the registration page said sold out when we checked. Apply anyway, and have 200ms as the Friday fallback if you trade or build DeFi.

Two big rooms publish no figure here. Breakpoint and the Defence Winter Dinner read "paid" with no price on our listing. BSI's conference reads free, but its own listing publishes no price either. Open the checkout before you commit the day.

That's the week

Olympia or Clerkenwell, the full list is on the London page. Running something on the off-chain side of town? Send it in. The newsletter carries the picks every Friday morning.
