Read a text transcript of this video

For growing businesses, managing IT becomes a job in itself. You've got a team to support, people joining and leaving, and a business that needs to stay secure. That's what we take care of at Little Big Tech — IT and security support for professional services firms in London, typically ranging from 5 to 50 people in staff. We look after your team day to day, including joiners and leavers. We manage and secure your technology. We give you a clear stance of where you stand with our Technology Resilience Score, and we give you a roadmap on what to improve next. And that matters more than it used to — cyber attacks are becoming more targeted than they did just a few years ago, and insurers are expecting more from your security. I work for the businesses that come to Little Big Tech for exactly that reason. Now, most IT providers will tell you that they're responsive. 99% of support tickets get fixed the same working day, and 100% within the SLA agreed. And that's not just our marketing figures — our security and service performance is independently verified every six hours, against the framework that UK regulators use for critical national infrastructure. We're the first managed service provider to do that. That verification sits behind your Technology Resilience Score — your technology today, and where it's heading. The pricing is on the website: £75 per user per month, 10-user minimum, one rate, no hidden fees. And if you already have an IT provider, we handle the switch — we speak to your current provider, manage the handover, and, most importantly, keep your team working through it. If that sounds like something you've been looking for, we'll look at where your technology stands, where the gaps are, and whether Little Big Tech is the right fit for your business.

How we do it

We measure it

Your Technology Resilience Score™. Most firms your size sit at 3.5 or below before we start — we show you what to fix first.

Your Resilience Score shows what your current provider hasn't been doing.

Your Resilience Score gives you a baseline from day one, so you know what improves.

We're accountable for it

We're the first MSP to hold the Assurix Trustmark — our performance is independently verified every six hours, not self-reported once a year.

Cyber Essentials support included.

We guarantee it

We'll make your business more resilient in 90 days. If we don't, we stop charging. See the 90-Day Resilience Guarantee →

Support figures are pulled from our internal support records — spam, duplicates and abandoned tickets excluded, and “same working day” means within our support hours excluding time waiting on the client. The live Assurix portal is temporarily offline while some reported errors are fixed.

“Little Big Tech have supported our business for about 4 years now. My emails were hacked and LBT instantly stepped in — Matt and John were on the case before I even knew I had a problem.”

Karen Woodbridge

“Computer was hacked, Matt and John from LBT acted immediately and shut everything down, saved more problems and then set to work restoring everything. Efficient, friendly and knowledgeable.”
