About REG121

An AI website builder that goes further than a page.

Every site comes with a real, working backend. Describe the business. REG121 plans, writes, and builds a live site with the database, forms, and application logic to match.

Not a static page pretending to be a product. A live site with the backend to match.

Built by two founders

One builds the product. One takes it to market. Both working on the same problem: a live site with a real backend, not another page generator.

Co-founder & CEO

James Gibbons

Product and engineering

James built REG121 after years as a fractional CTO and running a Nottingham web studio. He leads product and engineering, and designed the platform so a business description becomes a live site with a real backend.

Co-founder & CRO

Alistair Stafford

Revenue and go-to-market

Alistair leads go-to-market and revenue. A two-time founder with one exit, he joined to take REG121 to market so small businesses can get a proper site without the agency wait or generic AI output.

A working tool, not a generated page

Tell REG121 what you do and who you serve. It plans the site, writes real copy, and builds it live. Add a booking form, a quote request, or a contact page with saved submissions. REG121 builds the actual database structure behind it, not a mockup.

Keep shaping it in chat or on the page

From a single action to a published site, usually in a couple of minutes. Then you keep shaping it the same way.

Start with an existing site

Bring a site you already have onto REG121 with the import wizard, then keep shaping it from there.

Start with the site wizard

A handheld, step-by-step flow that prompts the AI to plan, write, and build the site from your description.

Keep shaping it live

Tell REG121 what to change, or point-and-click on the page. The site stays live. The backend stays real.

What REG121 is for

Built for websites that do real work

REG121 is designed to build websites and simple web applications that stay in the realm of a website. That is the product. A live site you can publish, edit, and run enquiries through. Not a promise to invent any software you can name.

A real backend, on every site

REG121 Cloud is the secure network behind every published site. Database, forms, and application logic run on it, and it is included free on every plan.

REG121 Cloud on every site

A secure managed backend behind every published site. Forms, data, and hosting run on the same network.

Included free on every plan

Free, Pro, and Agency all include REG121 Cloud. There is no backend add-on and no separate bill to turn it on.

Dedicated cloud per site

Every site gets its own dedicated REG121 Cloud. A managed Supabase backend, just for that site.

Most AI builders give you a page. REG121 gives you a working business tool.

No templates to wrestle with. No technical setup.

Enquiries land somewhere real, viewable from the dashboard.

Each site keeps its data in its own isolated database boundary.
