About Theo

Theo is an AI agent that builds your small business website in minutes, then works on it every week so customers find you, whether they search Google themselves or ask an AI. Theo studies your site, your market and your search data, picks what will win the next customer, and ships it: a page for what people are searching for, a post that answers their question, or the fix that was holding you back.
