About Us: the the small stuff journey

  • The beginning of a dream

    (Founded: 3rd October 2019)

    Passionate about sales

    Our story begins with a spark of inspiration in the soul of Susie Mathieson. An experienced sales professional with a career spanning from telephone sales to key account management and sales leadership positions, Susie discovered her true calling during a sabbatical in March 2019.

    A chance encounter with a German traveller in Da Nang, Vietnam opened her eyes to her natural ability in understanding and inspiring people. She realised that her passion for helping people win at sales was not being used to its full potential and that's when the idea for the small stuff was born - a company specialising in sales training, focussing on the people first.

  • The Pivot

    (May 2020 – April 2021)

    The Birth of the digital sales revolution

    It was in the spring of 2020 when the world changed unexpectedly. The Corona pandemic hit companies hard and forced us all to rethink and adapt. This also posed a challenge for Susie: How does she reach and support her customers when face-to-face meetings are suddenly no longer an option?

    She soon found the answer through a creative mindset and the digital world. Susie developed a virtual pub quiz. On evenings or weekends, teams and groups of friends or family, who couldn’t be with each other physically, gathered in a virtual room to solve puzzles together and test their general knowledge. This digital format was not only a response to the isolation and distance brought about by the pandemic, but also the first step in a new direction. Susie discovered her passion for virtual training methods and began to develop the idea of digital B2B sales training.

  • The climb

    (Summer/Fall 2020)

    Growing together

    As the business world slowly learned to live with the new circumstances, the small stuff began to thrive. The digital B2B sales training developed by Susie met with great interest. It wasn't just the innovation that attracted attention, but also the effectiveness and accessibility of the training.

    In September 2020, the small stuff reached a significant milestone. The hard work and commitment bore fruit when the collaboration with a renowned German telecommunications company started. This success was not only a highlight in our young history, but also the beginning of a lasting and fruitful partnership.

  • The expansion

    (February 2023)

    Innovation meets expertise

    Our continued growth led to the investment in an eLearning Platform - a move that underlines our philosophy of fun, interaction and digital learning. We firmly believe that our participants are not just there to listen, but active designers of their learning experience. This concept has helped us develop training methods that are both practical and memorable.

  • Dynamic duo

    (June 2021)

    Revolutionize Digital Training with Cutting-Edge Social Selling Strategies

    During this time of growth, Susie found a new team member – Franziska Morin. With her expertise and enthusiasm, Franziska and Susie became a dynamic duo that refined our digital training methods. Together they recognised the importance of social selling, especially via LinkedIn, and firmly integrated this strategy into our training system.

  • How to Sell Virtually

    (Summer 2023)

    Bookboon awards book contract to Susie as an expert in digital selling

    Susie was asked to write a book reflecting on the changes in the business environment since March 2020. She decided to bring on the expertise of Keith Rozelle, who co-authored the groundbreaking book. It offers innovative approaches to bridging the gap between in-person meetings and virtual encounters.

Thank you very much for your valuable tips and insights! I had the pleasure of getting to know Susie during the multi-day sales training. Her workshops are excellently prepared and provide real added value. As a sales beginner, she was able to impart a broad foundation of knowledge to me. At the same time, Susie always took the time for individual questions and issues. Her open and humorous manner greatly enriches the sessions. I can only recommend training with Susie. Dear Susie, I wish you all the best and success in all your endeavors! Thank you for your time and dedication!

We have worked with Susie for several years now. She is the best trainer in our industry. She is passionate about her work and has an amazing ability to read the room and change the agenda on the move to perfectly fit the audience.

Every single one of us at DANX Carousel have positive words to say and I would recommend in a heartbeat! Keep doing what you are doing Susie and don’t ever change!! 💕

I recently had the pleasure of working with Susannah Mathieson. She was my sales trainer as part of a further education program. Overall, I must say, I couldn't have asked for a better sales trainer. Not only professionally, but also personally, Susie is truly outstanding. She managed to dispel our fears and create a harmonious atmosphere within the team, allowing us all to learn from each other additionally. We all start somewhere and just need the right people around us to push us forward. The exchange with Susie has opened up new perspectives for me, and I feel more confident in my job in general.

My team and I had the pleasure of being coached by Susie in Berlin. Within a few days, she was able to promote substantial growth within my team. Boasting sharp awareness, she is in tune with the struggles that one may have and addresses those struggles with quick, accute solutions. Being a newcomer in my company, I often experienced draining spouts of insecurity and doubt in myself. Susie quickly took note, took the relationship that my team had, cultivated it, and influenced an evolution that instilled the confidence that I, as well as some of my fellow peers, had previously lacked for success. The most difficult part was seeing Susie go, but the impact that she left on my team and me will remain everlasting. Thank you, Susie!

I have the honour to work with Susie as a Trainer from RAIN Group for our Inside Sales Team of T-Systems International. Words can't really describe how much Susie has helped me personally to gain more confidence as a sales person, especially because I had no prior knowledge to sales itself, since I came from a totally different background. Susie taught me to believe in myself more, to use both my strength AND weakness, because we're all only human, and that it is the most important aspect of selling itself. I also really appreciate that Susie, even though she has a lot of knowledge in a lot of aspects (not only the niches!), she never once gave me the feeling that she was being condescending, but purely there to help me and my team to move forward. I can only recommend her enough to everyone that is interested and passionate in Sales to work with Susie!
