About Calibre

Built on experience.
Driven by results.

Calibre Marketing has been helping businesses grow for 25 years. We are a virtual agency of marketing specialists, spread across the South East, with deep sector knowledge and a genuine commitment to the clients we work with.

Our story

Started on two sheets of A4. Still flying 25 years later.

Calibre was founded by Martyn after he woke in the middle of the night with an idea. He wrote it down on two sheets of A4: the name, the model, the first clients. The name comes from the hot air balloon he flew with his father at the time.

That handwritten plan became a professional marketing agency that has now worked with clients across more than 20 sectors, many of them for over a decade. Two of those early prospective clients are still customers today.

We are a virtual agency, spread across the South East of England. That means we stay close to our clients, keep our overheads low and pass that efficiency on. We are not a big agency with a big price tag. We are a focused team with broad experience and a straightforward approach to getting marketing done well.

Impartial advice

We are not tied to any one marketing discipline. We recommend what is right for your business, not what suits our revenue model.

Real people, real experience

Many of our team have run their own businesses. We understand the decisions you are making because we have made them too.

Transparent pricing

Fully costed proposals with no hidden surprises. You know exactly what you are getting before you commit.

Long-term relationships

Many of our clients have been with us for more than ten years. We measure success by how well your business grows, not by how many new clients we sign.

Why clients choose us

What makes working with Calibre different

We do not try to be everything to everyone. We focus on doing a small number of things exceptionally well.

01

Full-picture thinking

We look at the whole customer journey first: objectives, gaps, audience and data. The marketing plan follows from that, not the other way around.

02

Sector knowledge that runs deep

Over 25 years we have built genuine expertise in more than 20 sectors. We come up to speed quickly and we understand the audiences you are speaking to.

03

An extension of your team

We work alongside your existing team, not separately from it. Many of our clients treat us as their outsourced marketing department.

04

Flexibility built in

Our virtual model means we are responsive, adaptable and cost-effective. No big agency overhead, no unnecessary delays.

Martyn and his team were very helpful in promoting the opening of our new office, getting a prominent local politician to perform the opening and also local press coverage. They were also very good at sourcing local leads for us to contact to grow our business. Martyn is very thorough in his approach to raising awareness of companies, and his ultimate goal is to generate more leads for your business to grow successfully.

Working with Martyn at Calibre was a joy from the start. I’ve not much of a head for marketing but they enthusiastically listened, spent time understanding my business and walked me through developing clear messaging for my brand. They were also full of ideas of their own. I whole-heartedly recommend Calibre.

Ryan Barker
Director · Zylo Performance (Drama Classes & Tuition)
★★★★★

I spent a couple of months back and forth with multiple marketers trying to find a match. After a few calls with Calibre, I decided they understood what I was trying to achieve and had a grasp on my target industries more than the many others I spoke to. I have found them to be excellent communicators with a clear plan of action and timeline. I definitely made the right decision to go with Calibre.
