A case in Mexico City
A free two-day hackathon during Mexico Tech Week to build with open source AI and open-weight models. Every team could use the partners' tools and credits, among them n8n, ElevenLabs, Lovable, Miro, Linear, Firecrawl, Tavily and JetBrains, plus MLH perks such as Render, DigitalOcean and .tech.
On October 27, at Dev Townhouse, the teams formed and Sergio Nouvel, co-founder and CEO of Get on Board, spoke to the builders. On the 28th, at Sandbox Hub, they built with mentors, Abimael Martell of Firecrawl among them, and demoed live for the jury.
Futuro won, a tool that guides students to find their vocation; Budi came second, an open source Chrome extension that turns what you save into audio lessons; MedVox came third, with voice-dictated clinical records for doctors. FarmaRadar calls neighborhood pharmacies with an AI voice to find medicines that ran out, and DocAPILab turns API documentation into local sandboxes. Budi, Bench-Engine and DocAPILab published their code.

The latest was Hacktoberfest México, on October 27 and 28, 2026, and the next is Mobil3 2027, a hackathon and builder residency.

Yes. Students, first-time builders and experienced developers can join. Hackathons are the best place to start: you build something real, meet the companies and people working on it, and win prizes when the program includes them.
Founders in Mobil3 programs get software, credits and support from companies we work with. Tell us what you are building through the founders form and we tell you which perks apply to your stage.
Yes. Mexico City is our base: we run the Mobil3 Hackathon, with participants from 12 countries in its 2025 edition, in-person build sessions for developers and open coworks for builders, along with programs for companies, universities and government.
It depends on the format. The latest hackathon was Hacktoberfest México 2026, on October 27 and 28, 2026, at Dev Townhouse in Colonia Juárez and Sandbox Hub by Igeneris in Polanco; the Mobil3 Hackathon 2025 was at Publi.co Reforma. Build sessions and coworks run in city venues confirmed at registration, and programs with companies or government run where the audience is, including university campuses.
No. Programs for founders, developers and students are free, and Mobil3 never takes equity. The companies and institutions behind each program cover its cost. You keep everything you build, and you get mentorship, startup perks and direct access to the companies involved.
