Startup Day Yucatán Kickoff: Time2Build Live From White Paper House

On Thursday, October 9, 2025, we’re lighting up Mérida. From the White Paper House, PlebLab will host Startup Day Yucatán — Kickoff with Time2Build, a live builder session welcoming new contributors into Time2Build, showcasing demos, and streaming the action to the global builder community.

Date: Thursday, October 9, 2025

Time: 1 pm

Location: Mérida, Yucatán

What: Live kickoff for Time2Build with builder onboarding, demos, Q&A, and a livestream

Time2Build is a worldwide developer challenge to bring Bitcoin to the world’s leading open-source applications and services using the Breez SDK. It is designed for sustained adoption, not short-term hype. The goal is simple. Ship real Lightning features into real open-source projects. </time2build>

Why the Breez SDK? It provides developers with a best-in-class solution for developers to integrate self-custodial Lightning into their apps and services, removing third-party dependencies, and enabling value to move as easily as information. You can learn more from the documentation here.

The Kickoff Flow

We will open our hackerspace to builders this fall and guide contributors through:

• Onboarding to Time2Build

• Live demos from teams integrating Lightning with the Breez SDK

• Q&A with builders and maintainers

• Livestream to bring in the broader community

WhitePaper House is the home base for the day, a beacon for builders in the heart of Yucatán.

Why Now

There has never been a better moment to Build on Bitcoin. With Time2Build, your contributions are directly integrated into open-source repositories that people already use, and the Breez SDK reduces integration friction across languages and frameworks. The promise is practical. Make Bitcoin and Lightning feel invisible for users, while keeping custody in the user’s hands.

What Winners Receive

In addition to the $25,000 Prize Pool, PlebLab is offering a Startup School Residency for the winning team. This is an invite-only hybrid tuition residency in PlebLab’s 2026 Startup School. Tuition is fully covered, books are included.
