For execs and solopreneurs
You have the AI tools, and you're still the one keeping track of everything. Nexus is your always-on assistant, with one memory every AI shares and a private portal built around you.
The problem
Which chat was that in? Where does that project stand? What do I need to know before this meeting in five minutes? Follow-ups, decisions and who said what still live in your head, or get lost across siloed apps and chats.
The solution
Nexus takes the keeping-track off you: an always-on assistant, either a frontier agent like Claude or ChatGPT or your own self-hosted one, that follows your work, meetings, messages and tasks; one Brain every AI you use reads and writes; and a private portal with tools built for how you work.
How it works
Swipe sideways to see the whole picture →
Each one reads the Brain first and leaves a signed note when done.
Notes are screened and filed into a page per project and person.
Tomorrow, any agent you open already knows the context.
Your portal
Your portal gets tools and workflows made for how you work, and new ones whenever you need them. A few that clients start with:
One page each morning: what changed, what needs you, what can wait.
Notes, decisions and follow-ups filed to the right project and person.
Where every client, deal and project stands, at a glance.
Turn any page into a clean link for a client or colleague.
Tools you pay for monthly, rebuilt inside your portal to fit you.
Name the job; we build it into your portal.

Case study
Nexus runs RAIZOR's own work every day: several assistants, one Brain, and a portal we keep adding tools to.
"It started as one agent I messaged on Discord. Now it runs across several assistants and computers, every day." Douglas Campbell, founder

Private, zero-retention models are billed per use, so they cost more than a subscription. That's why a Custom Agent saves them for private work.
Start with a Frontier Agent and move to a Custom Agent later. Your Brain and portal come with you.
For your team
The Soma Platform gives everyone on a small team their own agent, all working from one shared team brain, with approvals and a full log.

Your Brain lives on a private server set up just for you, never in a database shared with anyone else. It's plain, readable text pages with a full version history, so every change can be traced and undone. It's yours, whichever AI platforms you use or cancel.
Your Brain stays on your private server either way. The difference is the agent. With a Frontier Agent, your chats happen inside that platform, so what you type and what the agent reads from your Brain fall under its terms, including whether they're kept or used for training. Business and enterprise plans usually give you more control.
With a Custom Agent, the agent runs on your private server too. We work with providers that offer every major model, most with zero-retention and end-to-end encrypted options, so no single platform's terms decide what happens to your work. You pick the model for each task, and everyday work can still run on regular subscriptions to keep costs down.
Obsidian and Notion are a great start for one person working with one agent. Nexus is built for what comes next: several agents, a small team and a lot more information.
It stays fast as it grows, several agents can add to it at once without overwriting each other, and every change is signed, so you always know which agent or person added what. And nobody keeps notes by hand: your agents write as they work.
Claude, ChatGPT, Grok and most other AI platforms, plus custom agents built on any model. You can use several at once.
Notes land in an inbox first and are screened before they're added. From the portal you can edit, move or delete any note, and because every page keeps its history, any change can be rolled back.
No. We set it up for you: connect your tools, load your projects and people, set your approval rules and walk you through it. Anything that costs money or acts on your behalf can wait for your OK.
No. The Brain is plain text pages you can export anytime, and it works with whichever agents you use. If you switch platforms or stop, your projects, people and history go with you.
Built for how leaders work
Most start with a Brain & Portal Setup. A 15-minute call is enough to see if it fits.
