Prime Assist is an AI receptionist made in London by Gateway Global Ltd. You buy from the company that builds it, which writes your UK or EU processing region into the contract and names the clinician accountable for clinical safety.
UK healthcare still answers its calls on infrastructure designed for a different decade. The people who suffer are patients who cannot get through and reception teams asked to do the impossible.
We built an agent that treats the phone as healthcare's front door: answered at once, handled properly, written back safely. Nothing more clinical than that, and nothing less reliable.
Prime Assist is an administrative tool with hard edges: it never gives clinical advice, it escalates to humans by rule, and every action it takes is logged and reviewable.
Our Clinical Safety Officer, Dr Humzah Jessa, signs off the clinical safety case under DCB0129. We publish results only with evidence and permission.
Prime Assist® and GATEWAY GLOBAL LTD.® are registered UK trade marks of Gateway Global Ltd. Patent pending: Gateway Global Ltd has filed three UK patent applications. Your data stays in the UK or EU region written into your contract, and the value created stays in the UK economy.

Omid Arbab is the founder and Chief Executive Officer of Gateway Global, the London AI company he started in September 2023. His aim is to make advanced technology accessible to everyone.
Most technology is still built for people who already find it easy. Omid builds for everyone else: the patient who speaks a different language from their doctor, the person who struggles with apps and websites, the caller who rings when no one is free to answer. He has started where barriers cost the most: healthcare.
An engineer by background, Omid has been a technology entrepreneur since 2014, and his first company grew into a Microsoft partner. He has spent his career in cloud infrastructure, cybersecurity and applied machine learning.
He also works to make it easier for smaller UK companies to bring safe AI into the NHS. In 2026, Gateway Global submitted written evidence to the House of Lords Science and Technology Committee on why UK small businesses find it hard to deploy technology into the NHS.
Omid is a finalist in three categories of the Global Innovator Awards 2026: Emerging Founder of the Year, and, with Heshmat Shoja, Co-Founding Team of the Year and UK SME Global Expansion. The winners are announced on 16 November 2026.
“Technology isn’t finished until the people who find it hardest can use it. That is the test I set for everything we build.”
Founder and Chief Executive Officer
Founded Gateway Global in London in 2023. Cloud infrastructure, cybersecurity and applied machine learning.
Chief Technology Officer
Has led engineering since the company began.
Marian is our CTO, turning ambitious ideas into products that actually work outside a slide deck. They make machines listen, systems talk, and prototypes survive contact with reality.
Resident diagnostician for servers, models, and “it worked on my machine” syndrome. Powered by tea, curiosity, and a deeply personal grudge against unnecessary latency.
“Teaches computers to listen so doctors and patients don’t have to type.”
Chief Operating Officer
Runs the company’s operations.
Vice President of Engineering
Leads engineering delivery with the Chief Technology Officer.
Danial Farzaneh is Vice President of Engineering at Gateway Global. He works alongside our Chief Technology Officer, Marian Podmajersky, to deliver products that work in practice.
His approach centres on forward-deployed engineering: working directly with clients, learning how their teams work day to day, and building AI that fits the systems they already use. With a background in software development and cloud infrastructure, he connects product engineering with deployment and day-to-day operation.
Chief Medical Officer and Clinical Safety Officer
Practising doctor who leads clinical risk management and signs off clinical safety cases.
Board Advisor
Joint Chief Executive of Pall Mall Investments.
As founder of Cavendish Group International in 1998, Ben established a platform through which companies across industry could expand their export activities to rapidly emerging economies such as Brazil, Russia, India and China (BRIC).
He went on to head the team at Emsworth Corporate Planning, where he was responsible for raising substantial inward investment and supporting the business in becoming a Government endorsing body for the Innovator visa scheme. Biography from Pall Mall Investments.
Buying voice AI on a slide deck is how people end up with something that fails on the first awkward caller. So we made the product itself easy to try before you commit to anything.
Ring the line, choose a scenario, for example a dental practice or a trades business, and talk to Prime Assist the way one of your callers would. Ask it to book you in, then try to catch it out. No form and no email address.
Call +44 20 3747 7785We only get in touch if you ask us to.
Two questions show the calls you miss today next to the same calls with Prime Assist, where every call is answered at once. Add your own figures to see what they are worth, what answering them would cost from £150 a month including VAT, and how many of your bookings that price equals.
Run my numbersNo email needed: nothing you enter leaves your browser.
Bring the three calls that waste the most of your team’s day. We run them live, in your sector’s language, and tell you honestly which ones we would not take. One short form to book.
Book a demoNo card, no sales sequence, one human reply.
Do all three, in that order, and it takes a little over half an hour in total. We would rather you tested the product than read our claims about it.
Ask how it is built, where the data sits, and who is accountable when it goes wrong.
Or ring the live line first: no booking and no form.
