Sources conflict a bit. The most consistent and current answer: Jason Guerrettaz is the founder of Website Closers, with Ron Matheson as co-founder. A recent franchise listing names Jason Guerrettaz as CEO of the firm, which serves as a technology and internet business M&A brokerage.
Other directories (Seamless.AI, ZoomInfo) list different or older names, so those appear outdated. Based on the company’s own site and most recent listings, Jason Guerrettaz is the best-supported current answer for CEO, alongside his role as founder.
