Mind Games AI Hackathon + Exclusive Napa Retreat

The BSH × XTrace AI Hackathon Weekend
Not your typical hackathon. We’re building agents that actually remember.
Join founders, engineers, researchers, designers, and operators for a two-week build sprint on XTrace’s memory infrastructure, ending with live demos and a private Napa retreat for winning teams.
The challenges are real, brought by industry partners, and designed for teams to go much deeper than toy prompts. Builders will tackle customer workflows, operational bottlenecks, knowledge transfer, decision support, and the places where agents break down when they lose context.
Teams build for the real world, use partner office hours to sharpen bold ideas, and present customer-relevant demos on stage. The best projects will show what changes when agents keep context across people, tools, and time.
Win prizes. Meet serious builders. Build something meaningful to customers.

What you'll make
You can explore pain points from industries and build an AI-native solution for it, including:
Restaurant
Accounting
Banking
Venture Capital
The panelists will also share their experience in each industry during the hackathon. If you don't have the ideas in mind beforehand, that will be a great time to get inspired!
Who should apply
Founders, engineers, researchers, designers, product builders, and operators who want to build useful AI agents around real business needs.
No finished startup idea required. Bring curiosity, execution, and a bias toward building.
Teams are 1 to 4 people: students, founders, and engineers welcome. Come with a team or form one at the Happy Hour.
