Our team

We combine our many years of experience in working with people and organisations in pursuit of our common goal: Contributing to personal and professional development and a fair and equal world.

We believe that objective (self-)knowledge enables people to make better choices, both professionally and personally.

We believe in a fair and equal world in which everyone can be their best self. We provide objective insight that allows you to make deliberate choices and develop yourself optimally, regardless of your background, ethnicity, education or age.

Gusta Timmermans, Founder

Thanks to her many years of experience in the staffing sector, as the co-owner of a recruitment and selection agency and as Head of Recruitment at ING Netherlands and ING Global, Gusta has become a true expert in her field.

In 2018, she started her own strategic consultancy firm, Recruitment Builders, which provided advice to organisations on staff recruitment and retention. Gusta has also written two books: 199 Questions for a Successful Selection Interview and, in 2021, Recruitment and Employer Branding Handbook.
