AI in business and sales
Cases of people using AI to sell more or spend less time on the boring parts of running a business: prospecting, proposals, competitor analysis, pricing, lead follow-up and reports for partners. There are accounts from freelancers, small companies and larger sales teams. Before copying, check whether the source shows a real result or only an intention, and remember that customer data calls for care under Brazil's LGPD. Each page covers what was done, how it went and a prompt to try in your own context.
33 cases, 15 of them from Brazil, from newest to oldest. The tools cited most here are Claude Code, ChatGPT, and Meta Muse. People who show up most in these accounts: salesperson, business owner, and entrepreneur.
