About the job

About the Company

Kasagi Labo is acquiring anime IPs and building an AI-powered social platform that connects fans and creators more effectively than traditional methods, automating and enhancing interactions like fan engagement and content creation, and proving so innovative that it’s fostering a global community and redefining anime fandom. We’ve raised one of the largest seed rounds in SEA totalling US$20M to build out our vision. The team is small because we can’t hire great people as fast as the company is growing.
