What we do
Two things, done properly.
01 · Managed IT
Secure, cloud-native IT, looked after by someone who knows your setup.
Email, files, devices and security, set up to the Cyber Essentials controls from day one. No call centre and no one new every time: you speak to the person who set it up.
Managed IT02 · AI-native software & agents
Tools built around how your practice actually works.
Client portals, document handling and the repetitive steps between your practice software, your inbox and your clients. We build them for accountancy & tax firms and run them on infrastructure we already secure, so client data stays where it should.
AI-native software & agentsSecurity
Built for firms that hold sensitive client data.
An AI tool is only as safe as the environment it runs in. Because we manage that environment, we know where your data lives, who can reach it and exactly what each tool is allowed to touch.

Why one partner
Anyone can write software now. Can they make it secure, reliable and built to last?
Every partner is being asked what the firm is doing about AI, and AI has made software cheap to write. Plenty of IT providers and agencies will now offer to build you something.
Writing it is the easy part. What decides whether you can rely on it is everything else: keeping it secure, keeping client data consistent as it moves between systems, building it so it can grow with the firm rather than be rewritten, and someone still being there to support it next year. Left to itself, AI often gets the first three wrong, and plenty of builders move on once it’s delivered. In a 2025 study of more than 100 AI models, nearly half of coding tasks came back with a known security flaw. And only one UK IT provider in four shows any security accreditation at all.
That’s our job. We’ve written production software and secured IT for years, so we engineer for security, consistent data and change from the start. Then we stick around to run and support what we build.

Questions
About JDLT
What is JDLT?
JDLT Ltd is a UK technology partner for accountancy and tax firms, founded in 2017 by Jake Dowie. We provide IT support and managed IT, and we build AI-native software and agents that automate how a practice works, then run and support them.
More about usWho do you work with?
Accountancy and tax firms, from new practices to established partnerships, and other professional practices that hold sensitive client data. Focusing on one sector means we know your software and your busy season before the first conversation.
Where are you based?
We’re a UK company, registered in London, and we work with clients across the UK. Almost everything a modern cloud setup needs can be done remotely; on-site work can be arranged when it’s needed.
Do we need to use both services?
No. Most clients start with one, usually managed IT or a single tool, and add the other when it’s useful. They work best together, because we already know the environment the software runs in.
