A one-day buildathon on "company brains" - the internal knowledge and workflow layer everyone is talking about and few have built. Lightfern is giving participants early access to its new Mac app before public launch, and the day is spent building plug-ins against real workflows, either your own or from scratch.

Open to all levels of AI fluency: seasoned builders, solo founders and operators. Up to 150 participants, first come first served at the venue, so a ticket does not guarantee entry once capacity is reached. Check-in from 09:30, Lightfern demo and sponsor talks, building from 10:45, team and track submission by 11:15, submissions close at 16:00 and prizes at 16:30. OpenAI credits provided; tracks run with Jumpstart and Round Treasury.

Why go: early access to an unreleased tool plus a day to build something you can take back to work. Best for operators and founders automating their own internal processes.
