Women in AI will host a full-day, all-levels hackathon with Lovable, where participants will build and publish working AI-powered apps with hands-on mentorship and 100 free build credits. The day will feature live demos, community voting, prizes, and support from Composio, an AI agent integration platform connecting LLMs to more than 1,500 apps.

Build a coordinated AI agent team that uses real software, retains context, and knows when to hand off work or ask for human help, using tools from H Company, Superlinked, Cognee, and BAND.ai. AI engineers, ML specialists, full-stack developers, and product builders will compete on task completion, coordination, and value, with $2,000 in prizes plus credits.

The three-day Physical AI Hackathon, hosted with X Square Robot, will put developers, researchers, students, and hobbyists to work building real-robot applications on a shared platform, with robot kits, compute credits, and support from the robotics team. Teams will compete for $9,000 in prizes, with qualified participants receiving stipends; X Square Robot brings experience building embodied AI models and hardware deployed in homes and logistics.

This founder-focused event will tackle practical pre-seed and seed challenges, from scaling growth and landing major customers to hiring and building reliable AI systems, with actionable takeaways and small off-the-record speaker roundtables. Speakers include startup founders, investors, and senior leaders from Cisco, OpenAI, NVIDIA, Atlassian, and other leading companies.

Boat Hackathon will challenge builders to ship a project from aboard a boat, with selected teams demoing for investors and fellow builders at an invite-only showcase. Participants will have access to Boat.dev and Context.dev, and the grand prize will recognize the best private AI build.

Participants will reimagine everyday appliances as strange, misbehaving “smart” products, developing speculative product pitches and lifecycle concepts for a shared online catalogue. The 2.5-hour collaborative workshop will be led by Sang, an Assistant Professor of Human-Centered Design at Cornell University and director of the Machine Poetics Lab, whose work explores human-technology relationships.

An AI insider will explain why trillions are flowing into increasingly powerful AI and examine the risks that could threaten humanity. The talk will focus on ways to prevent the worst outcomes.

The Big Hack Game will pit Stanford against Berkeley in a one-week sprint to build, launch, and grow AI products for real users and enterprise challenges. Participants will get mentorship from YC-backed teams, job referrals, and free boba at the campus kickoff.

An upcoming n8n.io and AIC Club build event will have participants create projects solo or in teams, with free n8n credits, swag, pizza, and prizes on offer. Attendees will bring their laptops and ideas for a no-code creative session.
