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.
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.
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.

Why now
The market leader is in federal court, new privacy laws keep arriving, and recording devices are about to be everywhere.
→Our vision
The problems we will solve: eldercare with dignity, hospitals that say yes, deals off the record, robots that forget. Fifty stories. Press play and listen.
→The founding
Why we started Cull: the mission, the method, and the patents filed before anyone was watching.
→The team
The engineer who built Otter.ai's speaker AI, a Stanford PhD AI researcher, and the attorney behind a billion dollars of patents.
→The governance OS
Record less, keep what matters: consent checked before anything is saved, and signed proof of what was destroyed.
→Roadmap
Meetings now; clinical, pharma, wearables, vehicles; then the humanoids. Milestones an investor can verify.
→The world is filling with machines that listen and look.
Someone has to own the decision about what they keep.
