Our History

How we Started

In 2021,

Stewart Mathieson Operations Ltd (branded as FractionalClients.com) was founded and started implementing organic marketing solutions for clients in late 2021.

In 2022,

we worked with coaches and consultants based in the US and UK, averaging 5-15 qualified sales appointments booked for them per week.

In 2023,

we were able to scale up and began working exclusively with Fractional Executives. Since then, we’ve worked with over 100 people, securing over $3M in fractional clients.

In 2025,

we were getting so much success with consultants that we started RetainedClients.com to better serve that wider area of the market.

Daniel Beck
Fractional Sales Leader

Writing a full throated endorsement for Stewart Matheson. His team has met and exceeded every expectation and been extremely accommodating as potential conflicts and challenges have arisen. He and his team are outstanding and I look forward to collaborating with them for a long time.

Faron MacNeal

Stewart and his team are great! Communication is swift and professional and they were willing and prepared to try a number of strategies until they find success!

While working together, Stewart took a personal investment in my project and ensured the CRM they provided for response tracking was uploaded and working smoothly.

I highly recommend Steward and his team to anyone looking to grow!

Sarah Benteau
Fractional Sales / Marketing Leader

It was a pleasure having Stewart and his team assist us in launching our business development outreach. They did a good job creating our personas and outreach copy, which helped us engage the right-fit leads. As a fractional sales leader, I understand the effort and consistency it takes to excel at BD. Stewart has created an effective service that allowed this important part of the funnel to be given the attention it deserves while freeing up my time to focus on other areas of our business.

Lewis Chawko
Fractional RevOps Leader

Stewart and his team assisted me in launching my sales outreach. They started with strategy, understanding my ICP and the ideal sales copy, which meant we had better responses and engaged the right buyers. Afterwards, we entered the outreach phase where the team consistently drove results, kept me in the loop with weekly updates, and notified me when a lead was interested and if I had any actions to take. This helped me stay focused on my work and meant the outreach got the attention it deserved and I only got involved when it was time. Great way for fractional execs to outsource to people who are better at the pipe gen than they are and buying back your precious time! Thank you Stewart and team!

Kevin Hagemoser
Fractional Operations Director

We worked with Stewart to create a client acquisition strategy for myself as a Fractional Operations Director. His marketing advice was insightful and his knowledge about getting clients as a Fractional Professional was top-tier. His integrity, communication and commitment to results made him a pleasure to work with!

I highly recommend him to fractional executives looking to land new, more lucrative roles.

Mike Reardon
Fractional CRO

I hugely recommend Stewart Mathieson at FractionalClients.com. We connected at an opportune time as I was pivoting my company in a different direction or approach to my clients. So, I really appreciated Stewart's frank, direct, and fresh approach with how I wanted to pivot.

The bottom line is that his efforts, approach, and results (including 2 CRO offers) created unexpected interest in my new approach. As Stewart states on his website: if you are seeking fractional opportunities, then call on him to help you do so!

Gary Ng
Fractional CMO

Finding good fractional CMO opportunities certainly isn't easy. However, Stewart reached out to me via LinkedIn, walked me through his process and we begun working together.

Within just a few weeks, I secured my first client through his campaign, which more than covered the cost of his service. I've gained a lot of valuable insights from Stewart, and his approach is direct and very results-driven. Stewart's excellent communication and integrity stood out to me most, but most importantly, he genuinely cares about the success of my business.

Mitchel harad
Fractional CMO

Stewart and his team helped me take my fractional CMO practice from an idea to full client load in just a few months. He provides great advice on how to structure your offering and land clients, and the team is skilled and efficient at doing outreach that works. I've been particularly impressed by how they test, track and improve messaging and targeting.

People love to tell you that LinkedIn is dead and that business development firms don't deliver. They've clearly never worked with Fractional Clients.

Joseph Pellegrini
Marketing Consultant & Fractional CMO

ETM Partners engaged with FractionalClients.com in Q3 2024. They were professional, reliable and most importantly, highly effective. In terms of the number of prospective client meetings scheduled and the quality of those connections, they outperformed stupendously. I highly recommend their services and can also recommend Stewart as a person of high integrity and diligence.
