About Job Bank

Job Bank is a UK‑focused platform helping people start recruitment and training businesses through two simple annual plans (£100 & £200). We are now building Job Bank AI — a specialised AI system designed to help users create and scale their own recruitment or training business.

Our AI ecosystem includes:

• Recruitment AI
• Training & Course AI
• Business Builder AI
• Marketing/Outreach AI
• AI Assistants (Recruiter / Trainer / Business Coach / Operations)
• Business Engine (AI Tool Suite)

We are building a vertical AI platform, with deep industry‑specific intelligence — NOT a generic chatbot.

This is your opportunity to become a foundational part of a fast‑growing AI product used across the UK.
