Why this niche exists
Lawyers, doctors and accountants handle information that can't go into a cloud chatbot. Many of them still want an AI assistant to draft, summarize and search their own files. The answer is an assistant that runs on the practice's own machines, so client data never leaves the office.
Setting that up for them is a service, and it's the one this article covers.
What the work involves
The software is free. Ollama and LM Studio both run open-source models locally at no cost. What a client pays for is the setup: choosing a model that fits the practice, getting it running on the right hardware, and keeping it working.
You need a solid grasp of local AI and open-source models, and the patience to troubleshoot. Linux and networking help, especially when several computers in one office have to reach the same assistant. Every install is hands-on, so this is a personal service, not something that runs by itself.
The numbers
Kairo's data puts this niche at high margins with little competition. A typical time to a first client is around 45 days.
Startup cost is close to zero if you already own a capable GPU. An RTX 40 series card is plenty. If you don't, budget for the hardware first. Once a setup is running, maintenance and update contracts turn one-off jobs into recurring income.
Where clients come from
These buyers don't respond to ads. They respond to people they can check. Referrals from other professionals, LinkedIn and industry events are the usual channels for this kind of client.
Trust is the main thing you're selling. Credentials help, and so does a clear, plain explanation of how the data stays on-site. Each sector also has its own rules on professional secrecy and data protection, so learn them early and put them in your pitch.
How to start
Pick the profession you understand best. Build a working private assistant on one machine, document how it handles a typical task, and use that as your first reference. A single clean demo does more for a law firm than any brochure.
