What is an easy niche and offer to start getting clients with?

If you want something ready to go, Votel recommends the law firm treatment compliance system in the Snapshot Library. Hardly anyone targets that problem, there are lots of personal injury attorneys, and it is built on a system that works.

The offer: make sure the firm's clients attend treatment every month to preserve case value, and email the firm a report every time the AI speaks to someone. You can offer it free for a week, or with risk reversal (they pay and get their money back if they do not like it). The lowest risk for the client is nothing upfront, and a lawyer receiving a weekly report of clients attending treatment is unlikely to say no.

It does not connect to the client's CRM or case management system. The firm gives you a list, the AI calls or messages the people, and it emails the report showing who did their treatment, who did not and who did not respond at all. That keeps it working for every law firm, whatever tools they use.
