About Theo
Summary
Theo builds and continuously optimizes websites for small businesses so their customers can find them on Google and in AI-powered search. An AI agent handles the full workload: constructing the site, identifying ranking opportunities, and shipping weekly updates, whether new pages, targeted posts, or technical fixes. It replaces the piecemeal work small businesses would otherwise spread across freelancers, agencies, or their own time.
Business model
Subscription plans (pricing page listed on site), with a free site audit and a free site-build tier as entry points.
Go-to-market
Small business owners are the buyers; they enter through a no-login free site audit or a free website build, then convert to paid plans for ongoing SEO work.
From the Y Combinator listing
The site-builder and engine that gets your business found.
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.
