What they say

These references point to my ‘earlier’ career before starting with statistical data analysis: 20 yrs within sales, analysis and journalism mainly for startups. I trust that soon clients & partners related to statistical data analysis will join.

Carsten did an extensive technical documentation for the delivery of an industrial marking machine to our Spanish client, ArcelorMittal SA. The document was of high technical specialty. Carsten collected the data across our organization, and did progress reporting throughout the project. Both our client, Arcelor Mittal SA, and we, were most satisfied with the professional manner in which Carsten handled this job.

As a head of the regional rehabilitation hospital, Montebello, Malaga, I participated in Carsten’s project, which involved the establishment of a rehabilitation and wellness center in southern Spain. My role was to assist Carsten with knowledge in the field of rehabilitation and organization, as well as visiting.

I see Carsten as a entrepreneurial and inspiring person who is capable of learning new, complex material and to master the small details and to keep the overall overview. In addition, I experienced him as a strong project manager, capable of communicating and selling complex concepts, with an empathetic and welcoming kindness – an immediate key to trustworthiness . It has been a great pleasure working with Carsten.

I headhuntet Carsten as I knew him from earlier positions.

Carsten is a top sales and data professional even within sales of highly complex and technical solutions. He converts complex into simple – in many languages.

He treats and manages the clients in an exquisite manner and knows how to balance the here-&-now closure of a sale with the long term client relation. He was No. 1 in sales throughout the period (measured in units, figures and long term relations).

With his entrepreneur attitude he opened and developed a network of sales agents and through training, support and motivation he turned this into an efficient source of sales for our company.

Carsten might not be a control freak – but he likes efficiency. He optimized our logistics and our internal communication and increased productivity throughout our organization.

Carsten never sits still waiting for the next call. Then he rather goes knocking doors.

Peter Suurballe

Director, Acom Electric SL

In our start-up IT company Carsten built up the sales department and the client portfolio from scratch.

Based on his sharp analytical skills, Carsten developed and implemented working procedures and systems. He streamlined the company and the working procedures.

As interface between our clients and our technical department Carsten …. ensuring our clients’ absolute satisfaction.

Canvas sales were the main source client portfolio development and Carsten mastered the balance between long term client relationship vs. the urgency of closing a sale.

Our IT systems and services were, at the time, new to the market which resulted in relatively long sales processes: 1) awareness of the product; 2) interest; 3) desire 4) closing the sale and initiating after sales. Carsten mastered this process and immediately obtained understanding of our clients’ businesses.

As interface between our clients and our technical department Carsten elaborated data system requirements and organized and executed user training programs with our clients ensuring their complete satisfaction.

Carsten is a top professional in all the applied business disciplines: business and system development, project management, sales and CRM. He is a fast and efficient learner of even high technical issues and I hereby recommend Carsten as a loyal, emphatic and thorough partner.
