About Tofu
How do you distinguish between real and fake in an AI world?
This question has crippled the recruiting industry overnight. Tofu is building one of the most important companies of our time and the layer to fix it.
AI has made it easier than ever to fake credentials, impersonate real people, and apply to jobs at scale using synthetic identities. More than 60% of remote applicants are fake, there were 75M detected deepfakes last year, and the number of state-sponsored groups hired by Fortune 500s grew 220%.
The hiring funnel has become the front door to the enterprise, and AI has cracked it wide open. It’s a $96 billion problem that needs to be solved.
We’re changing that.
Tofu is building a new standard for security in hiring.
If you want to help build the trust layer for the internet and redefine how identity works in the AI era, we’d love to talk.
