One Month. Weekly Pushes. Real Traction.

SundAI and AI Tinkerers are joining forces for the Spring Epic Sprint—a recurring series of high-intensity building days every Sunday in April. This is the Startup Track for the most ambitious AI developers in Paris to bridge the gap between experimental code and venture-ready products.

We have dropped the “-athon” because this event focuses on 100% cooperation, real-time collaboration, and hands-on learning. We are building a high-signal environment for practitioners to ship weekly updates, gain real users, and prepare for fundraising this summer.

The April Sprint Goals

This series is designed for builders who live to write code and hack on messy experiments. Whether you are optimizing a mid-thought steering capability in a custom LLM or orchestrating autonomous agents using the OpenClaw framework, the focus is on growth and technical discovery.

• Weekly Cadence: Every Sunday from 10am to 6pm.
• Growth Focus: Pushing updates to gain real users and traction.
• No Fluff: No slides. No pitch decks. Just the code and the “how-to” behind your build.

Event Details

• Dates: Every Sunday in April (Next session: April 12th, 2026)
• Time: 10:00 AM – 6:00 PM

Who Should Attend

This event is strictly for active engineers, researchers, and technical founders. We screen all registrations based on demonstrable technical work (GitHub, LinkedIn, or technical portfolios) to ensure every person in the room can “pop the hood” and contribute to deep-dive discussions on model inference, tool-calling, and agentic loops.

Partner

SundAI is a 501(c)(3) non-profit organization dedicated to empowering the next generation of AI-first innovators. By focusing on rapid prototyping and community-driven learning, they provide a platform for builders to turn ambitious ideas into functional AI applications. SundAI fosters a collaborative environment where developers and creators can access the resources needed to navigate the evolving artificial intelligence landscape.
