[UK] What’s the Current Landscape of Recruitment Software?

As a software developer with over ten years of experience, I’ve contributed to several custom software projects for recruitment agencies.

I’m considering developing my own multi-tenant recruitment software that can be licensed to agencies, supporting both temporary and permanent placements, along with features like invoicing, bulk communication, and calendar management.

What is the current state of software solutions in this sector? Is there a genuine demand for improved software that can serve as a primary system for agencies and consultants? How do the existing licensed software options stack up? Are there specific leading companies that agencies typically turn to for management systems?

I’m looking to assess whether this idea has potential.
