The Invus team has a background in strategy, operations and consulting. But the most important common denominator across the team is our passion for business. We operate as a collaborative and inclusive team, where ideas, impact and teamwork shine. We continue to look for team members who share our values and want to help leaders transform their industries.
One of the major benefits of our evergreen structure is that we don’t need to raise new funds and manage investor relations across multiple funds. This frees up significant amount of our team’s time, allowing us to focus on our mission empowering entrepreneurs and executives to transform their industries.
Our relationship with owner-managers is not confined to formal board meetings. We enjoy an open dialogue with our owner-managers and frequently interact with them as they seek our advice on issues facing their businesses. This allows them to move rapidly without red tape. On select strategic projects, owner-managers can also call on us, where we can deploy one or more of our team members to be part of a project–specific task force to more deeply assist management with a new initiative or acquisition.
