Musubi Secures $5 Million in Seed Funding

Musubi keeps online platforms safe with revolutionary trust & safety AI

SANTA BARBARA, Calif., Feb. 26, 2025 /PRNewswire/ -- Musubi, a pioneering artificial intelligence platform transforming Trust & Safety through adaptive AI content moderation, today announced it has raised $5 million in an oversubscribed seed round. The funding was led by J2 Ventures with participation from Shakti Ventures, Mozilla Ventures, and existing pre-seed investor, J Ventures. Founded by the former CTO of Grindr and OkCupid, Musubi is set to revolutionize the Trust & Safety landscape with its innovative approach.

Global online platforms are facing unprecedented threats from sophisticated AI-powered bots, fake content, misinformation, and scams. Human moderation can't keep pace, and existing solutions are increasingly circumvented by bad actors using AI offensively. With victims of online scams losing over $100 billion globally, new defenses are urgently needed. Musubi's first-of-its-kind Trust & Safety AI autonomously learns from and works alongside moderators, delivering better-than-human performance with unlimited scalability.

"We're at a pivotal moment where online safety has never been more essential. While bad actors grow increasingly sophisticated, we now have groundbreaking technology that surpasses what was previously possible. It's a transformative time for everyone in the industry," says Tom Quisel, CEO and co-founder.

The company's technology applies advanced AI and machine learning techniques, including large language models (LLMs) and generative AI, to understand complex behavioral signals and content patterns. This allows Musubi to proactively identify and mitigate a wide range of issues, including spam, scams, fraud, hate speech, harassment, and age-inappropriate content.

"I like that Musubi accurately detects fake and scam accounts in moments," says Aaron Rodericks, Head of Trust & Safety at BlueSky, one of Musubi's early adopters.

Currently protecting over 45 million users, Musubi has already secured partnerships with industry leaders in the dating, social media, and marketplace sectors. The company has experienced rapid growth, quintupling its Annual Recurring Revenue (ARR) in the last quarter alone. Its underlying multi-modal AI system can be leveraged by any trust & safety or fraud team as a security layer to automatically detect users likely to cause harm.

"With ever-increasing threats and harm online, it's more important than ever for the public and private sector to solve this problem together. We're excited to partner with the world-class team at Musubi to set new benchmarks for online safety," J2 Managing Partner and Co-founder, Alexander Harstrick.

The new funding will be used to expand Musubi into new verticals and bring the latest AI research to market as Trust & Safety solutions. For more information about Musubi and its AI-powered content moderation solutions, please visit www.musubilabs.ai.
