Our Mission
To democratize access to AI by enabling secure collaboration between enterprises and a global network of developers without compromising data privacy or control.
Our Story

Bitgrit began in Tokyo with the vision of making artificial intelligence more accessible to everyone, not just large tech companies. The founders saw that while talent was spread across the world, opportunities were not. To bridge this gap, they created a platform where businesses could share real-world challenges and data scientists everywhere could compete to solve them.

What started as a competition platform quickly grew into a global community with tens of thousands of members from more than sixty countries. Along the way, Bitgrit partnered with organizations like NASA, SoftBank, and the Tokyo government, helping connect skilled developers with meaningful projects and career opportunities.

Today, Bitgrit stands as both a hub for global AI competitions and a provider of enterprise AI solutions, helping companies securely integrate AI into their workflows. At its core, Bitgrit remains committed to its founding mission: to democratize AI and build a fair, inclusive future for innovation.
