“The greatest advantage of joining a group like Perseus is the peer-to-peer connection. As a business leader, you’re no longer operating in isolation—you can share experiences, gain insights, and learn from others. While we may be in different markets with different products, we all face similar challenges. Being a part of this organization has made it easier for our team to learn from others’ successes and exchange ideas.”

“One of the biggest advantages of Ibcos and Catalyst operating under the Constellation Dealer Group is access to resources that most smaller businesses don’t have. Since joining, we’ve seen remarkable growth which has been driven by the expertise and support of the Dealer Group. Their resources enable businesses to scale strategically while ensuring minimal disruption to daily operations.”
