How do you search billions of faces or vectors in under a second? Typical databases lookup by name and email. This looks up by similarity. And doing that at scale is hard. We had to get our own data center as well for that. Typically if you're buying a facial recognition system, there's a cold start problem. What photos do you put in there? So police departments might have their own mugshots but they don't have mugshots from other police departments. And we just realized there's trillions and trillions of web pages on the internet and on social media and you know, news sites, mugshot websites.
