Extraordinary Outcomes
Come from investing in the right foundations, enabling you to go further, faster
What's The Deal With The Shark?
It's because what we do, isn't about the tech!
Hi, I'm Gary, owner of Grenadier Computing.
That shark; that's a Tiger Shark!
And that diver in front of it? My daughter, age 12, totally calm and enjoying life 20 meters below the surface!
No cages. Just me, her, our guide (just out of shot) & the shark; well there was actually 6 of them.
People often ask me why would I let her do this.
The answer is simple: mindset.
I want her to grow up understanding that extraordinary outcomes don't happen by accident. They require the right mindset, and then the investment to back it up.
Not just money, though yes, that too. But investment of time, effort, planning, training, discipline, the right equipment & the right team.
It's the same mindset I built Grenadier Computing on.
The businesses I work with don't settle for technology that "sort of works." They invest in foundations that let them scale, automate, and focus their people on what actually matters: growing the business.
If you're running a growing business and you're ready to stop fighting your technology and start leveraging it, I'd like to hear from you.
How We Work
Every business we work with starts in the same place: the foundation. You can't automate on unstable ground, and you can't benefit from AI when your data is scattered across disconnected tools. Once the foundation is solid, the next steps are yours to choose.
The Foundation
A secure, properly configured Microsoft 365 environment. Devices managed centrally. Identity protected. Data backed up. Unlimited support included. Your team calls us the moment something isn't right. No hesitation, no invoice.
This isn't break-fix. We take full ownership of your technology foundations so you can focus on running your business.
Managed
Endpoints
Every device managed, patched, and secured centrally. OS updates, security policies, encryption, and application control pushed automatically. If a device is lost or stolen, we can wipe it remotely. Windows, Mac, iOS, Android.
Exceptional Security
as Standard
Multi-factor authentication, conditional access, tenant hardening, email threat protection, web filtering, phishing simulations, and cyber awareness training for your whole team. Data backed up and recoverable. Not an add-on. Every client gets this from day one.
24/7/365
SOC
Human-led threat hunting and response across your endpoints and Microsoft 365 identities. Malicious processes isolated in minutes. Hijacked accounts locked down automatically. Rogue apps detected before they do damage. If something suspicious happens at 3am on a Sunday, our SOC is already on it.
Team Changes
Included
New starters get their accounts, email, devices, security policies, and application access from day one. Leavers are fully offboarded with access revoked, licenses recovered, and data retained or removed to policy. No gaps, no forgotten accounts sitting open.
Unlimited
Support
Log as many tickets as you need. Portal, email, or phone. No per-incident charges, no watching the clock.
Guaranteed
Response Times
Critical issues: 1 hour. High priority: 2 hours. Our average email response time? Under 15 minutes.
Virtual
CTO
Business-aligned technology strategy and leadership. We drive IT forward, not hold it back. Technology that enables growth.
One
Monthly Fee
Per user, per device. Paid by Direct Debit. No surprise invoices, no chasing, no credit terms to negotiate.
Uncover Pain, Automate & Agentify
The foundation tells us your technology is solid. But where should you invest next? That's where Pain Points comes in.
Your team tells you where the problems are
Alongside access to our IT support ticketing system, your team also gets access to Pain Points. It's a separate platform designed for a different kind of problem: the frustrations, workarounds, and manual processes that nobody raises but everyone puts up with. The platform calculates the real cost of each problem and ranks them by impact, so you know exactly where to focus first.
Explore the Pain Points Platform
See what it really costs and who it affects
Every pain point shows the estimated annual cost, how often it happens, and everyone affected. The more people who confirm "I have this too", the higher the cost and the stronger the case for change.
Then we fix it with engineering, automation and AI
Once Pain Points has revealed where your team is losing time and money, we step in. We redesign the processes that hold your business back, replacing manual work with engineering, automation and embedding AI agents directly into your workflows. Faster operations, fewer errors, and people freed up to do the work that actually grows your business.
Access to the Pain Points platform is included with every managed service. The automation and AI work that comes from it is scoped and quoted as separate projects, so you always know the cost before you commit.
Meet the Team
The people behind Grenadier Computing.
Gary Goodson
Owner
Started coding at 8, landed his first commercial project at 14, and hasn't stopped since. From building enterprise platforms to running IT for growing businesses, Gary's happiest when he's making technology disappear into the background.
Dawn Goodson
Owner
15 years in the NHS taught Dawn that precision matters, whether it's blood transfusion or bookkeeping. She keeps Grenadier Computing running behind the scenes, so Gary and Harvey can focus on transforming yours.
Harvey Cave
IT Support Technician
Harvey ran IT single-handedly across three college sites before joining Grenadier Computing. Give him a problem and he'll figure it out, whether that's a firewall, a ticketing system, or something he's never seen before. That's just how he's wired.
We have a great team, but our clients choose us because of who leads it.
Every client gets direct access to me, not some account manager!
That means access to over 30 years of software engineering, systems architecture, infrastructure, business strategy, data, and security. Someone who deeply understands your business, applying the right technology, at the right time, supported by my team.
My first line of code was written.
Developed a booking system for a motorcycle training centre; my first commercial project and a lot more rewarding than a paper round!
Spent my summer holiday building software for a Nuclear Power Station.
Started my first full-time employed software developer job.
Joined a small financial services company as a software developer. Over 7 years I evolved that role into Head of IT, building the department from scratch, leading a team of 10, and architecting the software and infrastructure behind a UK Government-authorised scheme now protecting billions of pounds. During my time there, the company grew by 1,100%.
Founded Grenadier Computing.
Delivered countless technology projects for one of the UK's largest leisure operators, including designing and building a CRM platform deployed across 35 sites nationwide, integrating with booking systems, operational platforms, and payment gateways and helped drive a £50m increase in sales.
Started consulting with SME holiday park operators and kept seeing the same problem: businesses wanted to move forward with technology, but their foundations weren't ready. So I pivoted the business to include a managed service. Now I get those foundations right with our managed service, and then take them further.
Hired our first employee.
"You're Too Small"
We hear this one a lot.
We're not trying to become a 50-person company serving a thousand clients. That model exists and it's how you end up speaking to a different engineer every time, waiting in a queue, and getting generic advice from someone who's never seen your environment.
We stay small on purpose. Fewer clients, deeper relationships, senior people on every account. That's how we deliver the kind of service that bigger firms can't.
Direct Access
When you call us, you get us. Not a call centre, not a ticket queue, not a junior who has to escalate everything. You speak directly to the people doing the work.
Technology Over Headcount
When your IT is built right, things rarely go wrong. And when they don't go wrong, you don't need a big team firefighting. We've built our operation around automation, monitoring and proactive management, so a small team can do what used to take entire IT departments.
Senior-Level Attention
Every client gets senior-level attention as standard. There's no B-team. No rotating cast of engineers who don't know your setup.
Built to Stay Small
We use automation, monitoring, and proactive management to deliver enterprise-grade service without needing an enterprise-sized team. Staying small isn't a limitation. It's the whole point.
"But You're Not Local To Us"
We've never visited most of our clients, because we've never needed to.
How We Measure Success
Most IT companies prove their value by showing you how busy they've been fixing your problems. We'd rather you forgot we existed.
Other Providers
"We resolved 2,000 tickets for you this quarter!"
2,000 things that went wrong.
That's not a success story — it's a symptom.
The Grenadier Way
"Your team raised zero tickets this quarter."
Nothing satisfies us more.
The measure of great IT is what it doesn't interrupt.
It's the difference between a mechanic who sees you every month, and an engineer who builds something that doesn't break.
We're most profitable when you have zero issues. Our incentives are completely aligned with yours — and that changes everything.
Don't Just Take Our Word For It
Real feedback from real clients, straight from our support tickets.
"Cannot thank Gary enough as he went out of his way to help me even though it was after hours. I was really worried & he calmed me down & sorted the whole problem for me, even waiting nearly 2 hours for the scan to work before re-installing the programmes."
"Shout out to Harvey, on double checking a filtered quarantine request. Always keeping an eye on our security filters and ensuring that we know what it is we are requesting. Thanks Harvey!"
"Superb support as always from the Grenadier team. First contact resolution to get a team member back up and running swiftly."
"It is such a relief to have someone on the end of a phone to sort out any IT issues which are beyond me to sort out. I think your service is amazing."
"Fantastic support from Harvey at GC. Patient, courteous, understanding and a troubleshooting guru! Service above and beyond."
"Absolutely amazing service as always. Always there when you need them."
