The Company
Switchboard
My name is Mattias Asserståhl, and I’m a consultant at Adviser Partner. I began my career in sales as a traditional vacuum cleaner salesman at Electrolux. It was a fantastic learning experience, and that’s where I learned the basics—a clear sales process, listening, identifying needs, and building trust. Since then, sales has been my life and my passion.
Over the years, I have founded several of my own companies and guided them through the entire journey—from start-up to exit—through both good times and bad. This has given me a broad understanding of the entire business—from the strategic perspective of management to the day-to-day reality of salespeople. I know what it’s really like to take responsibility for results, people, and growth.
In the companies I ran, I used Adviser Partners’ methodology and saw the impact it had in practice—we increased the average deal size by over 300 percent, strengthened leadership, and realized that a structured, behavior-based approach delivers results. That’s why I chose to join Adviser Partners myself.
Today, I help companies increase their sales, improve profitability, and drive long-term growth. I work closely with my clients and view every assignment as a partnership. I support management with strategy and follow up to ensure the right things happen. I help and coach sales managers to build successful sales teams that achieve their goals, and I coach salespeople on how to succeed in every customer meeting.
I believe in a long-term perspective, structure, and clear leadership. Small changes in behavior and processes often yield the greatest results. My goal in these assignments is to achieve real growth—not just in the numbers, but in the entire organization’s way of thinking and acting.
I know that when strategy, structure, and commitment come together, something truly special happens. Let’s work together to create change that makes a difference in our results, in our team, and in our company culture!
As a sales consultant at Adviser Partner, Mattias Asseståhl is a true “superpro” who, through razor-sharp structure, leadership training, and coaching, takes sales organizations to new heights.
With a focus on proactivity, he transforms everything from meeting preparation to closing deals, which creates measurable bottom-line results and accelerates a company’s growth.
We Love Salespeople
After 35 years without going door-to-door, I’m picking it up again—and it feels like I never stopped. My muscle memory is still there, as is my instinct for closing deals. Just like in the ’90s.
In this episode, I share my journey from selling vacuum cleaners door-to-door to my current role training and coaching top teams in Sweden and internationally. Jonas Olofsson, CEO of Adviser Partner, and I talk about why the fundamentals of sales never go out of style, how the right role models shape you—and why the “numbers game” is still the brutal truth.
Listen now—and see if you're really doing the work that's required.
A well-organized sales department, with the right people in the right places who can take you where you want to go by being knowledgeable about every aspect of the sales process.
It is common for the sales process not to be clearly implemented. This means that it exists but is not known to the salespeople and is therefore not used. As a result, salespeople do not understand the value of having and following the sales process. Ultimately, this means that the company does not achieve the increased sales that a sales process normally generates.
A sales manager typically has a wide variety of tasks that differ from one another. Few sales managers know how to prioritize their tasks in order to continuously increase the department’s sales, but Adviser Partner trains sales managers to do just that.
Closing is a simple exercise—do they want to buy or not? If you get a lot of “no”s, that’s a sign of a problem earlier in the sales process. We’ll help you identify the problem and fix it so you get more “yes”s when closing deals.
