Who we are

We are a leading management consultancy company with a start-up mentality and a passion for business innovation and digital transformation. We have a dual mission: to deliver excellent and consistent solutions to complex client challenges and to encourage the development of exceptional individuals in an inspiring environment.

The company

As a leading management consultancy service provider we specialise in strategy, innovation and transformation. We help our clients to develop new markets, establish innovative multi-sector business models and drive technological and organisational change.

Our multidisciplinary teams are the link between the executive floor and the operational level – and the bridge between business and IT. We unite a start-up mentality with first-rate advice. The standards we set for ourselves are high, and we are passionately committed to our clients.

The mentality

Our clients are encountering new challenges on a regular basis: climate change, artificial intelligence, and biotechnology, to mention just a few. We help them to overcome those challenges by prioritising a successful outcome for the client over our company’s own interests.

Even when something initially seems impossible, our teams make it possible. They are intelligent and focused people with a powerful work ethic and the motivation to succeed. And if something really isn’t possible, we let the client know. Sometimes, when we’re looking for the best idea, we get into some pretty heated team discussions. That’s because they benefit the project. And it’s our mentality.

The project teams

We unite competent individuals who are committed to success and set high standards for themselves. We build high-performing teams with the ideal mix of generalists, experts and executives for each new project. As individuals we have our own specific areas of competence. As a team we work towards the collective goal of achieving the best outcome for the client. That’s why the team as a whole is greater than the sum of its parts.

The people

Exceptional people in an exceptional team. That’s ritzenhoefer & company.
