london

An evening at White City Place for biotech, medtech, diagnostics and digital-health founders on the unglamorous machinery that decides whether a spinout scales: IP strategy and when to file, the UK grant and early-capital stack (Innovate UK, SEIS/EIS, VC) and how to sequence it, what investors actually diligence in a science-led company, and the financial foundations that keep a biotech investor-ready. Hosted by Lightbringer, Novabook and WilbeLabs, with honest stories from founders who have made the lab-to-company jump. Panel and Q&A from 18:30, food at 19:30. Free, ticket types for founders, investors and ecosystem — approval required.

incident.io opens its doors for an honest session on what working at an early-stage company is actually like — comp, risk, scope and the bits recruiters leave out. Aimed at engineers and operators considering the jump.

with Katie Freeman-Tayler (Policy & Research Director, Internet Matters) · Anna Lindroos Cermakova (Researcher, DOHE & European EdTech Alliance) · Andrew Mellor (Co-Founder & CEO, LOQT)

techUK and BESA convene policymakers, researchers, school leaders and EdTech suppliers on the collision between safeguarding, screen-time and digital-equity policy. Government is backing AI tutors for disadvantaged pupils while consulting on screen-time limits and publishing AI product standards — the two panels ask whether that pulls schools in one direction or several, and how schools and parents are actually responding. Speakers include Katie Freeman-Tayler (Policy & Research Director, Internet Matters), Dr Anna Lindroos Cermakova (DOHE & European EdTech Alliance) and Andrew Mellor (Co-Founder & CEO, LOQT). Free, at techUK's St Bride Street offices.

with Timofey Markin (Founder, Game Factory) · Joy Ma (Consultant, Strategy&)

The London edition of AI Builders' monthly meetup, run by a 5,000-strong nonprofit community of practitioners. Demos of AI agents, OpenClaw, Claude Code and RAG from EU and Silicon Valley builders, plus builder tool demos, and a deliberately large amount of unstructured networking time over pizza and drinks. September's line-up: Timofey Markin on AI Game Factory, and Joy Ma of Strategy& on shipping with AI. Aimed at developers, ML engineers, data and product people and founders — some working knowledge of LLM concepts is assumed. Tickets are a donation (£10 bootstrapper/student, £20 standard); free tickets available on request so cost is not a barrier.

Speakers include Rio Shen, GM of EMEA at MiniMax, alongside Max Ryabinin, VP of Model Shaping, and Sarung Tripathi, VP of Customer Experience, both at Together AI. Expect technical depth and practical numbers rather than a product walkthrough, followed by pizza, drinks and open conversation.
