London — Week of 24 Aug 2026

Campaign Lab's bi-weekly civic-tech hack night at Newspeak House — build open tools for progressive campaigning alongside data scientists, developers and organisers. Beginners welcome; snacks and drinks provided.

An informal summer-evening drinks for London's startup and tech community — a relaxed networking session for founders, operators and ecosystem folk hosted by startup accountancy platform Novabook.

Ethereum London turns to DAOs: what the last cycle of on-chain governance taught builders, and what today's tooling does differently. Free, technical, and one of the more serious Web3 rooms in London.

A full day on how AI is actually being deployed inside financial services, hosted in NatWest's Bishopsgate offices. Built for people working in fintech rather than watching it, with a strong careers thread through the programme.

A weekend build sprint run by Cantor8 Tech with the Oxford, Cambridge and Imperial blockchain and fintech societies: one of the few multi-university hackathons on the London calendar this month.

London has a housing crisis and the data to understand it already exists. house london! is a one-day data sprint at Newspeak House bringing together data scientists, urban planners and policy thinkers to take the capital's planning and housing data and build the most compelling, well-evidenced story they can with it. No toy problems: real datasets, real inquiry, and outputs — policy briefs, dashboards, models — intended to actually shape how London gets built. Cash prizes for the best projects, voted by fellow hackers.

A one-day build session for people who want to make something physical rather than another web app. Bring a project or join one: soldering irons, microcontrollers and a room full of people who know what a pull-up resistor is.
