We’re an AI Website Builder that allows businesses to create beautiful, functional websites and applications. Customers can generate complete websites and applications from the ground up using our coding agent. Instead of manually assembling layouts, users prompt an AI agent that builds structure, content, and design in seconds. You can also edit the code anytime you want.
To support our community of millions of users, we are expanding the B12 Expert Marketplace and onboarding experts with strong technical foundations who are excited about vibe coding and AI-first website creation.
As a Marketplace Partner, you will work directly with B12 customers on DIY plans who want professional support building, refining, or enhancing their AI-generated sites. This is an independent freelance partnership opportunity for experienced builders who are comfortable directing AI output and stepping into code when needed.
The B12 Expert Marketplace is a resource for customers on DIY plans who want additional help with design, development, SEO, copywriting, or marketing for their B12 website.
Customers browse the marketplace and choose partners to hire directly.
