What is B12?

B12 is an AI website builder purpose-built for professional service businesses such as consultants, lawyers, accountants, coaches, and healthcare providers. Its AI generates a fully designed website from a short description, then adds a comprehensive client engagement layer including online scheduling, contract and e-signature management, intake forms, invoicing, payment processing, email marketing, and a contact manager. B12's AI Agent can draft blog posts, landing pages, and email campaigns automatically, making it a genuine business operating system rather than just a website builder. It is especially strong for solo professionals and small service firms that need to look polished and manage clients without a dedicated admin team.

✅ Best For

  • Independent consultants, coaches, therapists, lawyers, and accountants who need a professional website that also handles client intake, scheduling, contracts, invoicing, and follow-up emails, all from a single platform without juggling five separate subscriptions.
  • Small professional service firms of 2 to 10 people that need team members to manage client relationships through a shared contact manager and collaborative website editing without a dedicated marketing hire.

❌ Not For

  • Ecommerce businesses or physical product sellers who need a shopping cart, inventory management, or fulfilment integrations beyond simple service-based payment collection.
  • Designers and creative professionals who prioritise highly bespoke visual design and want full control over typography, layout, and animations rather than a templated AI-generated look.
