About IMPROOF
IMPROOF was founded in 2008 by Hans Savalle and Tom Touber. Both have technical backgrounds as engineers, complemented by expertise in business administration, finance, and IT. They have many years of experience at the C-level within a wide range of organizations.
What unites them is the combination of analytical acumen and practical experience. Not only in designing plans, but especially in implementing them—even when the pressure is high and the stakes are high. The experience of both winning and losing has shaped them. That’s why they understand what’s at stake, both in terms of substance and on a human level.
IMPROOF has since grown into a multidisciplinary network of more than 20 experienced professionals. The team consists of specialists in areas such as strategy, project and program management, finance, business, and IT. In addition, IMPROOF works with associate partners and an extensive network of professionals.
A key distinguishing feature is its strong academic foundation. IMPROOF collaborates with professors and researchers who are actively engaged at the intersection of research and practice.
They share the latest insights from fields such as leadership, organizational science, behavior, decision-making, and performance improvement, and translate these directly into practical solutions. Science is not an end in itself, but a means to support decision-making and maximize impact.
What characterizes IMPROOF is its approach to collaboration. Substantively sharp and critical where necessary, with robust analyses and well-founded decisions, but always with an eye for the person behind the role. Complex issues require focus and discipline, but also the ability to put things into perspective. Fun, humor, and empathy play an important role in this. Especially in difficult situations, they help reduce tension, build trust, and keep us looking forward together.
IMPROOF does not believe in one-size-fits-all solutions. Every organization and every situation requires a tailored approach, with attention to both the “hard” aspects (strategy, structure, numbers) and the “soft” aspects (leadership, behavior, culture). Results are important, but the journey toward them is just as important.
Want to make an impact at IMPROOF?
IMPROOF is open to expanding its network with experienced professionals who can bring something valuable to the table. You can join as an associate partner, a professional, or as part of the network if you have:
- Distinctive expertise that strengthens the network
- Extensive practical experience at the senior level
- The ability to combine analytical depth with strong execution skills
- Discipline in thinking, acting, and executing
- Empathy and an understanding of people and context
- The ability to put things into perspective, a sense of humor, and enjoyment of working together
Professionals from other fields are also welcome, such as elite athletes (players and coaches) with an Olympic medal and military officers who have proven experience in performing under pressure, leadership, and discipline in complex circumstances.
IMPROOF is not looking for run-of-the-mill candidates, but rather professionals who can bridge the gap between science, practice, and exceptional performance and who are eager to work with clients to achieve sustainable success.
