Cas Purdy
Founder & Executive Communications Counsel
Cas Purdy he/him
I’m the founder of PURDYPR, based in Chicago. I advise organizations through growth, transformation, scrutiny, and other consequential business moments.
I’ve spent more than 25 years leading corporate communications across cybersecurity, cloud, enterprise software, and renewable energy. My work spans rebrands, leadership transitions, high-stakes announcements, and long-term positioning efforts for global teams.
Most recently, I led brand and communications strategy for Amshore Renewable Energy as it repositioned itself in the market. Before that, I served as VP of Marketing & Communications at Trustwave, helping strengthen its position in managed security services ahead of its $850M acquisition by Singtel.
Earlier in my career, I held senior communications roles at Guidance Software, Forcepoint (formerly Websense), IBM, and Tivoli Systems.
Today, I advise CEOs, founders, boards, and communications leaders during consequential business moments—helping them clarify priorities, strengthen reputation, and communicate with confidence.
I work best with leaders who value disciplined thinking, calm execution, and communications as a business lever—not just a marketing function.
