Tech Events by TAG Amsterdam

A one-day hackathon on breaking and then hardening the AI agents now sitting inside audit, risk and compliance work. Red teams from Prosus and Skuridat attack the open-source agents of the Shared Audit Agents Framework live, and the room then builds the defences across the repository. Around 100 auditors, developers and security specialists, deliberately mixed so people who know what an agent should never do sit with people who can make sure it doesn't. Brought together by TAG with SAAF, Mollie, Prosus and Skuridat, hosted by Ben vanLeeuwaarde and Tijs Nieuwboer. Retimed by the organiser on 5 November: doors 13:15, programme 13:30 to 18:30. The start time shown above is wrong - it is 13:30, not 09:00. At Mollie, Keizersgracht 126. Registration needs host approval. Why go: live adversarial testing of agents in a regulated workflow is rare, and rarer with the auditors in the room rather than in the review afterwards.

The follow-up to the SAAF security challenge on 10 November, and the session where the open parts get closed. The agents, the audit criteria and the shared library are built; this day goes over every agent, fixes what the red teams found, and locks each fix in with a test. Three strands run through the day: repairing agents, checking each one against its audit criteria pass or fail, and tightening access, logging and sign-off across the framework. SAAF brings auditors and builders from more than 65 organisations together to build AI agents for audit work in the open. Hosted by TAG at The Stack, with Ben vanLeeuwaarde, Sofia Frumkina, Tijs Nieuwboer and Mathijs Schouten. BDO is title sponsor. Doors 09:00, hardening until 17:00, drinks to 18:00. Free, 50 places, 36 taken. Why go: agents for regulated audit work get hardened with the auditors who sign them off in the room, not in the review afterwards. Best for security and platform engineers putting agents near compliance decisions.

Headline event of Amsterdam Tech Week: a 45-hour AI builder tournament at The HUBB bringing together 500+ vetted founders, engineers and designers to ship real startup work, not weekend toys. Mentors and operators from Codex, Mollie, Miro, Peak Capital, Visa, Wispr Flow, Tulip Ventures and BabyVC are in the room throughout the weekend; €100K+ prize pool. Hosted by TAG — the Amsterdam builder community behind weekly ship sprints and demo nights. Applications vetted; free tickets via the public video-pitch route.
