ATILUS

Harry Casimir is the founder and CEO of Atilus, a Fort Myers, Florida digital marketing agency he started in 2005 while still a student at Florida Gulf Coast University. Originally from Haiti, Casimir holds a bachelor's degree in Computer Information Systems from FGCU and an MBA from Norwich University. He is also a U.S. Navy veteran, having served eight years before building Atilus into a full-service digital marketing firm. The company began operating out of his apartment in Bonita Springs and has since grown into a team of web developers and marketers serving clients across the Southeast.

Casimir remains active in the FGCU community, having served as Chair of the FGCU Alumni Association and currently sitting on the FGCU Foundation Board of Directors. That institutional grounding in Southwest Florida is reflected in Atilus's client base, which leans heavily on regional industries: marine and boating dealerships, home services, real estate, tourism, and nonprofits. The agency spun off a dedicated sub-brand, Boat Marketing Pros, to concentrate on the boating and maritime vertical that has become one of its signature niches.

Atilus's stated thesis is straightforward: small and mid-sized service businesses need a long-term partner who can own both the website and the demand generation side, rather than stitching together separate vendors. The firm positions itself as an extension of a client's internal marketing team, with retainers covering web development, SEO, paid search, hosting, and support. The public founder story focuses more on Casimir's educational and civic credentials than on a specific origin moment for the marine niche, which appears to have emerged organically from the agency's Gulf Coast geography.
