How we work
Listen, build, look after it.
We listen
We sit down with you and your team, ask what slows everyone down, and name the first thing worth fixing. A fixed price, credited if you go ahead.
We build
We build the system in your own environment, with your staff involved, connected to the tools you already use.
We look after it
One monthly plan covers updates, support and a plain report. No surprises on the bill.
Guides

What owners ask us first.
Will this replace my staff?
That is not how we work. We take the repetitive work off your team so they can spend their time on customers and decisions. Your staff help shape the system, so it is built for them to use.
I am not technical. Is that a problem?
No. You tell us how your business runs. We handle the technology and explain everything in plain English, without jargon.
Where is my data kept?
In an environment dedicated to your company. We do not pool client data, and you can ask us to delete what we hold.
Can I see the work?
Client names are withheld until each client agrees to be named. On a call we can walk you through the systems in more detail.
Who is Lead Handled?
An AI agency working with companies worldwide. Lead Handled is a trading name of Synthetix Consulting Limited.
Tell us what is slowing your business down.
A 30-minute call. We tell you what we would build first, and whether it is worth building at all.
