Who We Are

Perseus, an operating group of Constellation Software Inc., acquires independently managed software companies around the world. It provides them with the strategic guidance and financial security they need to become leaders within their respective markets.

Our philosophy

“We believe that small businesses should stay small. While other purchasers of business seek economies of scale through centralization, we have taken the opposite approach. We believe that potential is maximized when teams are allowed to remain small. This enables the General Manager of the business to be empowered and remain in control of all levers necessary to guide his/her business.”

Mark Leonard

President, Constellation Software Inc.

We don’t collect businesses. We nurture and help them grow.

We prefer to treat our acquisitions like people, not property. That’s why we do our best to ensure their growth and development.

Here are our core values:

Smaller is Better

Smaller is Better

If you have a small business, we’d like to work with you. Unlike large enterprises, small businesses are not burdened by bureaucracy, which allows them to achieve top-tier results faster and more efficiently.

In the past year, 35 out of our 40 acquisitions had fewer than 100 employees.

Growth Through Learning

Growth Through Learning

Learning is the key to success. Without it, your employees can’t become better at their jobs and your business can’t realize its full potential. That’s why we encourage employees across all our businesses to share their expertise and best practices with their peers through our functional summits, quarterly strategy meetings and annual academies. That way, we all grow together.

Career Flexibility

Career Flexibility

Is it better to lock people in their set roles or let them explore other career possibilities? We firmly believe in the latter – you and your employees deserve to select your own career path, whether it leads to retirement, staying put or taking on additional responsibilities, such as managing multiple businesses.

Trust Comes First

Trust Comes First

No one likes surprises. That’s why we’re happy to connect you with other business owners who have chosen to join us, many of whom are similar in size and scope, to help you get a clear picture of what it’s like to work with us.
