The name of our organization is based on our vision of the labor market and research: Toptalent can be found in the longtail and they behave differently on the labor market. Therefore, the hiring selection process of these individuals is a specialism.



We would like to assist you in the search for roles in a wide range of functional areas. We possess an extensive track record in mediating professionals in commerce (sales, marketing, business development, e-commerce), HR, and Finance. With regard to seniority levels, we focus on young executives (3 – 15 years of work experience) as well as managers, directors, and C-level executives.

Executive search

Clients and sectors

We provide services for both medium-sized businesses (often family or PE-owned businesses) and multinational enterprises.


Our search process is in-depth, enabling us to achieve an optimal match. Through an intake, we translate business challenges of our clients into recruitment sources and selection criteria. Accordingly, we identify and qualify suitable candidates. In the final phase, we focus on references and unify candidates and clients. A fundamental principle at Longtail is that we are evidence-based in our advice to both our clients and candidates.

Executives shaking hands


We are happy to assist you in your search for an interim professional. Longtail established an extensive network of interim professionals. Due to frequent contact with these professionals, we have a clear overview of their track records and availability. Fulfilling an interim role is often characterized by high urgency, therefore we developed an efficient process for interim mediation by which we can fulfill these type of positions within approximately one working week.

Personnel Psychology

Evidence Based

Research (O’Boyle & Aguinis, 2012) illustrates that a so-called ‘norm of normality’ is incorrect and that toptalent can, instead, be found in the longtail. This means that talent is not ‘normally distributed’ or centered around the mean. On the contrary, there are considerably more low- than highly talented people and the differences between ‘the best and the rest’ are tremendous.

According to research by McKinsey, toptalent could be up to 800% more productive than average employees (link). In other words, these talents can achieve results in a week which would take an average employee two months. At Longtail, we understand toptalent and their specific wishes and needs like no other. Recruiting and selecting toptalent is a unique profession (link). Because of our expertise and experience, we can be considered specialists in the recruitment and selection of toptalent. In the Longtail.
