Deep Tech London is co-organised by lachlan from londoncalling and bharat from DeSci London and our community partners — we need some help, so join us!

We’re running the week in partnership with Euro Defense Tech Days (EDTH & Resilience Media) and Deep Tech Week.

5–11 October 2026, around London. The flagship summit is Thursday 8th October at 93 Feet East — The Boiler House, in the Old Truman Brewery, Brick Lane, E1. Doors at 11:00. The full calendar for the rest of the week is coming soon.

A lot — the festival is one strand of a much bigger week. Euro Defense Tech Days runs 1–8 October, with EDTH’s London hackathon, a Counter-UAS forum and Build with Ukraine, plus the Resilience Conference on 5–6 October. London is also a stop on Deep Tech Week. Twenty-plus partner events are going up across the city — if you want to host one, get in touch.

It's an empty term, so we're taking a deliberately loose view. We know this will upset people. Deep Tech is people building hard things — ambitious problems, real science, genuine engineering depth. It's not about gatekeeping who counts. If you're working on something that could change a fundamental constraint of how the world works, you're Deep Tech.

We're not anti-B2B SaaS per se. B2B SaaS-ists are welcome to attend, enjoy themselves, and be inspired to do something better. We're prioritising stage time for the next revolution: automation at a different scale, science that moves atoms, intelligence that changes what's possible.

We're curating speakers rather than selling slots — if you're doing genuinely interesting work, reach out. For sponsorship enquiries see below.

Full refund if the event is cancelled or if the final details differ materially from what was advertised. If you're not as excited as us, no questions asked.
