Sales dominance through structure and behavior change

My name is Mattias Asserståhl and I am a consultant at Adviser Partner. I started my career in sales as a classic vacuum cleaner salesman at Electrolux. A great school and there I learned the basics - a clear sales process, listening and creating needs and building trust. Since then, sales has been my life and interest.

“I choseMattias Asserståhl when I was looking for a combination of a mentor and a professional development coach in 2018, during my time as a sales manager. I was very satisfied during our sessions, but looking back now that I’ve realized all the tools I received from Mattias and through Adviser Partners’ ‘training program,’ I appreciate the value even more.

Two of the reasons we chose Mattias were his solid experience in direct sales and his humble approach, but don’t be fooled—Mattias is much more than just a skilled sales trainer and a friendly guy from Värmland. I highly recommend him to anyone who is ready to grow and dares to think outside the box.”

“Apparently, Ididn’t know everything, despite having spent quite a few years in sales and customer service. AP provided fantastic support in digging into the details and getting a solid grasp of the process to help a buyer navigate the buying journey as efficiently as possible. It doesn’t all start with the details—we began by setting the goal, getting the entire company on board with it, and naming all the components involved. AP helps with the big picture, from strategy to detailed actions.”

As a result, we’ve improved the frequency of our meetings, understood the importance of better sales planning, and, through this, increased our sales. Highly recommended!

Jonas Olofsson, CEO of Adviser Partner, and I discuss why the fundamentals of sales never go out of style, how the right role models shape you—and why the numbers game remains the brutal truth.
