The Clero Story: How 2 UK Researchers Built an AI Voice Agent

Ahmad Abdelaal & Hashir Hamid

Co-Founders, Clero AI

The idea for Clero didn't start in a boardroom. It started when we realised that even the most successful businesses in the UK are losing massive amounts of money to a single, simple sound: The busy tone.

Combining Ahmad's background in high-stakes medical AI research at Moorfields with Hashir's engineering work at QMUL, we saw a gap. We weren't interested in building another "chatbot." We wanted to solve the human bottleneck - the moment where a great business loses a great customer simply because they were too busy being successful to answer the phone.

The Clinical Rigor Meets Engineering Power

At Moorfields, Ahmad was working on Eye2Gene, training AI to detect rare pathologies in retinal scans. In that world, if the AI is slightly off, the consequences are clinical. At the same time, Hashir was at Queen Mary University, building the infrastructure that automates complex marking systems for thousands of students.

We said that if we applied that same "zero-error" mindset to business telephony, we could create something revolutionary.

What happens when the "Lab" meets the "Front Desk"?

We've spent the last year perfecting a voice co-pilot that doesn't just sound human - it acts with the precision of a medical researcher.

For the Dentist: Clero understands the value of a hygiene gap or an implant consultation. It doesn't just take a message; it looks at your Dentally or SOE calendar and books the patient in, exactly as a trained receptionist would.

## Our Mission: Your "Always-On" Safety Net

We founded Clero to be the safety net for the UK's busiest industries. We believe that your staff shouldn't be stressed by a ringing phone, and your customers shouldn't be ignored by a voicemail.

By automating the "repetitive" side of the business - the bookings, the FAQs, and the intake - we're giving your human team the space to do what they do best: provide world-class care and close big deals.

From the lab to your showroom. This is Clero.

Bring clinical precision to your business phone.
