Founded by Colombo DiSalvatore, III in 2001, C4 Communications is a boutique technology consulting firm that has been serving SMB and small enterprise customers for the last 20 years. With a focus on mid-size customers — who are typically underserved by today’s telecom and cloud service providers — we deliver value through long-term, collaborative partnerships.

Colombo has a specific mission: to keep promises to customers, to earn and maintain their trust as a dedicated partner, and to make sure they get the solutions and support they need.

With a background in carrier sales, he was disillusioned with the business model that forced him to focus purely on new sales and left him unable to care for customers he’d brought on board. He knew he could offer what these customers truly needed, and founded C4 to make it a reality. Colombo put together a team with a few chief goals: always work with integrity and excellence, bring constant value to clients, and provide a work-life balance for himself and his team.
