Is private AI right for your company?

The decision is simple to state. Should your company's AI run on a server you own, or as a cloud service? This guide helps you choose, and shows what to check before you commit.

Private AI means the AI models run on a server your company owns, in your own office or server room. Your staff use it much like any chat tool, but the documents it reads stay on that server.

It suits many companies, though not every one, and cloud AI services are a good choice for plenty of work too.

When private AI suits your company

Private AI tends to suit companies whose daily work runs on their own records: purchase orders, supplier bills, price lists, stock and staff files. When agents work with those records every day, it helps to have the AI right next to them, on a server you control.

It also suits companies with several departments ready to use AI, that prefer one fixed project cost, and that want to own the system outright.

If your team is small and mostly wants help with general writing or research, a cloud AI plan may be the simpler place to start. Many companies use both, each for the work it suits.

What to check first

Start with the work, not the technology. Where does your team repeat the same checks every day? Which systems hold the records they need: accounting software, ERP, email, a NAS or file server, spreadsheets? Does each one offer an official way for other software to connect?

Then think about people and place. Who in your team will approve what the agents prepare? Is there a cool, secure spot with power for a server, and a local IT vendor who can check it on site? Branches can connect through a secure private link (VPN), so they do not need servers of their own.

What your company provides is short: one project contact, test logins, server space and power, and time for a walkthrough.

Sizing basics

Server size depends mainly on how many people will use the AI agents. As a starting guide:

The server is bought in your company's name from our hardware partner, so it is yours. A speed test confirms the size before you buy.

How it is priced

Private AI has a different cost shape from a monthly subscription: a project fee, the server your company buys, and optional support after go-live.

At Customnex the project fee is a fixed price by scope, with no per-user fees and a permanent licence. Adding staff does not add licence cost, so you can plan the spend.

The fee is paid across four milestones. Projects go live in 8–16 weeks, with a three-month warranty.

Launch pricing applies to our first five clients.

Questions to ask any vendor

Whichever route you choose, ask the same questions. Where is our data processed and stored? What does the AI connect to, and does it ask before it saves or sends anything? Who can see what, and is every action recorded? Who owns the server and the licence? What is left behind if support ends?

With Customnex, the agent asks in the chat before it saves anything. It answers customers directly only on the questions you choose; everything else waits for a person's OK. The admin guide and setup notes stay on your server, so your own IT team or another provider can look after it.

Each project is led by our founder and lead engineer, so you have one person accountable from walkthrough to go-live.
