CIOs, IT & Security Leaders: Worried about employees leaking sensitive data to ChatGPT?
Get a secure, company-owned LLM your team will actually use — without sending company data to external models.
Sum is a hosted "your own LLM" stack for SMBs who want AI without shadow-IT risk.
We're building a private LLM solution for companies who need AI but can't risk their data leaving the building. Our goal is to give your employees the AI superpowers they want, while giving you full control, audit logs, and peace of mind. If this is you, join early access.
The solution
We develop a structured cognitive model of your company's operational reality, and pre-train and post-train custom LLMs that "are" you. These LLMs are not just wrappers of public weights — they are your weights, and they act as you in the world.
What you'd get
- Stop employees pasting sensitive data into ChatGPT and other external tools
- Prove compliance with full audit logs of who asked what, and when
- Give staff an AI that actually understands your company's docs and policies
- Replace scattered "shadow AI" tools with one managed, approved AI workspace
- Get all this running without your team having to build new infrastructure
Preview
Ask your company LLM:
"Summarize our data retention policy and highlight anything that conflicts with using external AI tools."
"Summarize our data retention policy and highlight anything that conflicts with using external AI tools."

We respect your privacy and will only contact you about early access.
Hi, I'm Yusuf
I'm exploring whether this problem is worth solving at scale. I keep hearing the same thing from IT and security leaders: "We want AI, but we can't risk sensitive data leaving our environment." If this sounds like you, I'd love to talk.
