SafetyKit

SafetyKit replaces human content moderators with language models. Companies like Character.ai, Substack, Upwork, Faire, and Eventbrite use SafetyKit to find and remove bad stuff on their platform without hurting good users.

We’re ex-Stripe and Airbnb, repeat founders, and have deep connections and experience in our space. We work together in-person every day in a sunny office in the Mission in San Francisco.

We build on AWS serverless (Lambda, Step Functions, SQS), usingTypescript. It's fast and fun.

We use open source language models, big hosted models, specialized vision models to make users happy. We merge, eval, and ship new models the day they launch (if evals look good!).

Every engineer at SafetyKit works to understand our users' businesses and policies inside and out. That lets us push available tech to its limit and ship exactly what our users need faster than anyone else in the world.

We love managing complexity so our users lives can be simple. We have in-house eval tools, tools for debugging complex LLM execution chains, and lots of LLM-assisted code and infra generation.
