Is this self-hosted? If not, am I to work under the assumption that my company's IP is worth ~$0?

No self-hosted version yet. You would need to trust us in the same way you trust your other SaaS apps that host company IP (e.g. Slack, Notion, Github, etc.)

I get that's a big ask from a startup. If it helps, we are a company that's been around for 4+ years and have built a work tool (https://gather.town) used for 100k+ people for their daily work, Sequoia-backed, are SOC II certified, and go way beyond that for the security considerations for this product.

Are slack/github/notion dumping company data into an unknown set of LLM APIs under the hood?

(My company uses Zulip/Gitea/Affine for data sovereignty reasons, but this kind of thing seems worse)

Build the on-prem thing. Companies will be much more trusting.
