Best AI agents for small business: what real owners and teams actually use

I can't tell you which agent is "best" without inventing a benchmark, and I won't. What I can show is which tools small teams actually use for which jobs, taken from 387 sourced cases, with the results as the people involved reported them.

Before you hand an agent the keys

• Start with one job and read what the agent did before you trust it.
• Give it read access first, and keep payment and sending behind your approval.
• Keep business and personal accounts on separate agents. A CEO's finance agent posted his bank balances in a company Slack because two channels shared a name.
• Check your bank's rules before connecting money tools (several big banks now block personal agents).
