London — Week of 27 Apr 2026

Informal Monday-evening hack night at Newspeak House for engineers building agentic systems. Bring a laptop and a half-working demo — lightweight round of intros, open hacking, quick show-and-tells. A useful regular slot in the London AI agent-builder scene; the room skews to hands-on engineers and indie founders rather than enterprise AI.

Women in Payments' EMEA Symposium returns to London for two days of keynotes, leadership panels, and career development breakouts across the payments and banking ecosystem. Theme: 'Redefine Today, Own Tomorrow'.

Silicon Roundabout — the UK's biggest deeptech community — runs a structured bi-weekly online intro round. Quick, low-overhead way to surface who's building what in UK deeptech.

Weekly networking event for AI and tech professionals in the startup ecosystem. A consistent community format from Networxlondon, based at Sycamore Covent Garden.

ETHLDN teams up with Logos for an evening on sovereign, peer-to-peer infrastructure — Codex, Waku, Nomos and the Logos stack. Programming leans deep on cryptography, decentralised networking and trust-minimised systems, rather than surface-level crypto. Good room for protocol engineers, Web3 researchers and policy-curious founders.

The UK’s leading exhibition and conference for HR, talent and people technology, co-located with Learning Technologies. Two days of demos, keynotes, hands-on demos and networking covering HR tech platforms, talent acquisition, employee experience, payroll, learning and AI in the workplace.

Europe's flagship workplace-learning conference returns to ExCeL with 15,000 visitors, 200+ exhibitors, and 200+ free seminars — co-located with HR Technologies UK. The defining week of the year for EdTech and HRTech commercial conversations in London.

A friendly morning coffee for Greenwich and South East London founders to meet locally and trade notes. Good quiet-week filler for founders outside the central London circuit.

Codebar's weekly 1:1 coaching workshop for learners from underrepresented backgrounds, hosted at the FT's Bracken House. Students pair with volunteer coaches across JavaScript, Python, HTML/CSS, Ruby, React and data. One of the most consistently high-quality community slots in London tech; an excellent fit for career-switchers and for engineers who want to mentor.

LogRhythm's European cybersecurity summit lands at CodeNode with investigative journalist Geoff White as keynote. A focused day for the SIEM/SOC community — 150+ security professionals in one room.

Launch event for 'Are You a Software Update?' — a short book on how the metaphors we use for software (patches, updates, rollbacks) leak into how we think about selves, institutions and politics. Conversation with the author, drinks after. Draws the crossover Newspeak House crowd of engineers, writers and policy people.

Hands-on AI agent-building workshop for early-stage founders — go from zero to deployed agent in a single Saturday in central London. Practical, code-light format aimed at non-technical founders who want to actually ship.
