Cull.ai, Inc. · Incubated by PatentVC · Menlo Park + Bangalore

The governance layer for everything machines hear and see.

We protect privacy in transcription while keeping the benefits of what people record with consent. Decide before it is written. Prove what was destroyed. If that mission moves you, join us.

Built by the engineer behind Otter.ai's speaker AI · a Stanford PhD AI researcher · and the patent attorney behind $1B+ in licensed inventions
ONLY WHAT'S RIGHT IS KEPT.
The thesis in one line

People must be able to trust that every machine that listens, looks, or remembers will retain and learn from only what is appropriate. We are building that layer, the operating system for safe, privacy-first AI, and we own the patents on it.

The pattern we are following

We take inspiration from what has worked.

ElevenLabs solved voice generation, once, for everyone

Making computers speak was hard. One company solved it so well that everyone else plugs it in instead of building their own.

Anthropic made safety the whole company

Instead of bolting safety onto someone else's AI, they founded the company on it, and investors funded it for exactly that reason.

Cull does both, for everything machines hear and see

One layer that checks consent, follows the rules, and keeps proof. Built once, used everywhere: meetings, clinics, wearables, cars, and robots.

In one line

The world is filling with machines that listen and look.
Someone has to own the decision about what they keep.
