Overview

SafetyKit's AI agents do the dirty work for big tech and finance companies so humans don't have to.

Today companies rely on armies of low-paid outsourced humans to protect their platforms from fraud, harassment, and crime. It’s super important work, but the jobs are difficult and sometimes traumatizing, and it’s impossible to keep up. Our mission is to end this manual toil.

We learned this domain first-hand at Stripe and Airbnb, where first we built software for human reviewers, and then built models to replace them.

We’re a group of engineers from Stripe, Meta, Netflix, MIT, and Princeton that love language models and unironically love B2B SaaS. We know the economy is going to be rearranged over the next 4 years and we want to be in the driver’s seat.

We build vertical AI that works and have some of the world’s largest companies as paying customers. Patreon, Eventbrite, Upwork, Character.ai, Substack, Faire, along with a $10B+ marketplace, a $100B+ payments company, and more rely on SafetyKit in production.
