Private AI means getting the benefit of AI without handing your company's data to a public chatbot. I tell founders not to paste company data into ChatGPT for plain reasons: you lose control of retention and who can see it, client data under NDA should never leave systems you control, a general chatbot does not know your numbers and will guess confidently, and there is no record of what was shared.
What I build instead runs on data the business owns. At Vimal Electric Corporation, an internal AI tool answers retailer history questions that used to need whoever knew the account, and I had to limit some information to certain people after launch. For myself, a WhatsApp message every morning lists the emails that need action. These posts cover what that takes, and where it gets hard.
