The operating system for running a business.

Email, contacts, calendar, tasks, and proposals: unified, and quietly run by an agent that already knows the context.

The BusinessOS home screen: three agent suggestions at the top — a lead waiting on a quote, a pitch deck due Friday, and a dormant account — above open-proposal and overdue-task counters, a recent activity feed, and the Bos agent panel on the right.
Everything in one place

Six tools. One context. No more swivel-chair work.

Unified Inbox
Gmail and Outlook in one place, threaded by contact and deal, so you never tab-hunt again.
Contacts that update themselves
Contacts, companies, and deals stay current, pulled live from your email and calendar.
Calendar with agent scheduling
The agent proposes times, drafts the invite, and finds context from past threads.
Tasks with auto-triage
Follow-ups land in your task board automatically, already sorted, deduped, and owned.
Proposals & Files
Write, send, and track proposals. Your documents are searchable by every other surface.
AI where it matters
Not a bolt-on chatbot. The agent works inside every surface, reading your context and acting on it with your approval.

What BusinessOS is

BusinessOS is a unified workspace for small businesses. It brings email, contacts, calendar, tasks, proposals and files into one place, and runs them with an AI agent that already has the context of your business.

It connects to Gmail and Microsoft 365 over OAuth, so your inbox and calendar come along as they are. Contact, company and deal records stay current on their own, pulled from email signatures, calendar invites and meeting transcripts. The agent drafts replies, triages tasks and chases follow-ups, and you approve before anything is sent. It also speaks MCP, so you can work in your BusinessOS data from Claude, ChatGPT or any MCP-capable assistant.

Pricing is one plan: £39 per month including your first user, then £19 per month for each additional user, with 20 percent off if you pay annually. There is a 14 day free trial and no card is required to start.

BusinessOS is built by Nexus Data & AI Limited, a company registered in England and Wales under company number 17066175.

Frequently asked

Is my email and customer data private?
Yes. Your workspace is isolated per organization, encrypted at rest, and the agent only reads what you have already connected. We never train shared models on your data.
Which email and calendar providers are supported?
Gmail and Microsoft 365 (Outlook), each with its calendar, on the same plan. Both connect over OAuth, and you can revoke access at any time.
How does the AI work?
We use AI and machine learning throughout BusinessOS to draft replies, triage tasks, and surface what actually needs you. Every action the agent takes is recorded in your audit log, and nothing leaves your workspace without your approval.
Can I connect my own AI assistant?
Yes. BusinessOS speaks MCP, so you can connect Claude, ChatGPT, or any MCP-capable assistant and have it work in your workspace with exactly your own access. Each connection reaches a single organization, so connect each one separately if you belong to several. It can read and manage your work, but it cannot send email, invite people to meetings, or reach billing and team settings. Manage or disconnect it any time from Settings → Connections.
Can I cancel any time?
Yes. Plans are month-to-month, no contracts. Export your data at any time as a standard CSV.
Is there a free trial?
Yes. 14 days, all features, no credit card required to start.
How do you handle team security?
Every workspace is isolated per organization, with role-based access and two-factor authentication you can enforce across your whole team. For larger organizations with specific security or procurement requirements, get in touch and we will work with you.
