London — Week of 20 Jul 2026

A curated evening bringing together technology advisors, consultants, IT leaders, CIOs/CTOs, founders and business executives across AI, cybersecurity, cloud, enterprise software, data analytics, digital transformation, fintech and healthtech. Held at The Anthologist in the City, it's pitched at senior decision-makers and innovation specialists looking to build relationships, exchange insight and explore partnerships in a relaxed professional setting.

An evening of startup, tech and AI networking from Ascent Valley, whose founder-and-investor mixers run across 13 countries. Expect a curated, verified room of founders, engineers, product and growth leaders and investors, with structured introductions, short live founder pitches and time to build genuine connections. A solid mid-summer fixture for anyone in London's AI and startup ecosystem looking to expand their network.

London's biggest practical AI meetup returns for its July edition at Inspire St James in Clerkenwell. The recurring format runs three focused talks — a technical 'what I learned building with LLMs' session, a hands-on productivity demo, and a bigger-picture look at where AI is heading — followed by pizza, drinks and open networking with a large, high-signal crowd of AI practitioners, builders, operators and founders. Free to attend; RSVP ahead as spaces fill quickly.

Small-group conversation about AI, technology and how they reshape participation — structured around short imaginary scenarios with regular group reshuffles. A genuine alternative to the standard talk-then-drinks format, hosted at Newspeak House.

The strongest single-day engineering line-up in London this month, and the only conference built specifically for teams shipping AI in TypeScript. Fourteen-plus named speakers include Don Syme (Principal Researcher, GitHub Next), Sam Bhagwat (CEO, Mastra and author of Principles of Building AI Agents), Carly Richmond (Elastic) and Tyler Slaton (CopilotKit) — most of them among the first people anywhere to run production agents at scale, talking about metrics, failures and what actually held up. Two hundred seats at Convene 22 Bishopsgate, deliberately builders-only. If you own the stack or you are making the TypeScript bet, this is the room.

A full day of hands-on LLM security work led by Ian Ozsvald — PyData London co-founder and author of O'Reilly's High Performance Python. Expect prompt-injection challenges on Lakera's Gandalf platform, poking at abliterated models with guardrails removed, and a practical discussion of sandboxing and safe code practice. Free, small and tenth in the series; spaces are strictly limited.

An afterwork mixer for London's tech community — software engineers, data scientists, cybersecurity and cloud pros, product managers, founders and career-changers. Held every Friday from 5:30pm at The Clarence on Whitehall, it's a relaxed, low-pressure setting to expand your network, swap referrals and job leads, and talk shop across AI, data, IT and software. £3 online RSVP; no tickets on the door.

Campaign Lab's annual summer gathering on the Newspeak House terrace — the civic-tech and political-data community out of hack-night mode and into introductions. Open to anyone working at the intersection of technology, data and campaigning.
