Attention UK agencies! What technology do you use?

My partner and I are considering launching our own agency, bringing together 20 years of recruitment experience from both in-house and agency roles.

Having been away from the agency landscape for a few years (currently using Bullhorn in-house, which isn’t great), I’m researching the best tech stack to adopt.

I’ve observed that many of the popular software options tend to be US-focused, with some only available for payment in dollars instead of pounds.

To my fellow UK recruiters, what tools are absolutely essential for your operations? I would greatly appreciate your insights!
