About Mainline
Founded in 1989 by Rick Kearney, Mainline Information Systems has evolved from a single-vendor solution provider into a comprehensive IT consulting firm. Kearney, an entrepreneur from a young age, started the company in Tallahassee, Florida, with a small team of programmers. His leadership saw the company achieve significant growth, landing on the Inc. 500 list of fastest-growing privately held companies for five consecutive years. In December 2023, Mainline was acquired by H.I.G. Capital, a global investment firm, with the existing management team, led by CEO Jeff Dobbelaere, continuing to lead the company's operations. Kearney remains involved in other business interests and philanthropic activities, particularly those aimed at ending homelessness in his community.
Mainline operates as a technology solutions provider for enterprise and mid-market clients across the United States, with a client base of over 1,000 organizations. The company designs, implements, and provides professional and managed services for custom IT solutions. Its business model is centered on building long-term client relationships and acting as a trusted advisor, a strategy reflected in testimonials praising their consultative approach. Revenue is generated through the sale and service of these technology solutions, with an increasing focus on recurring revenue models through managed and staffing services. The company architects and delivers a wide array of IT solutions, including on-premises infrastructure, cloud and hybrid cloud offerings, cyber resilience, and software.
The firm's service portfolio is extensive, covering modern data center management, hybrid cloud solutions, cybersecurity, and advanced data analytics. Mainline holds top-tier partnerships with major technology companies such as IBM (as a Platinum Partner), HPE, Dell EMC, NetApp, Cisco, and Pure Storage. This allows them to offer best-fit solutions tailored to specific business needs. Specific offerings include expertise in IBM Power Systems, data and AI with watsonx, disaster recovery, network management, and data center optimization. The company has also expanded its capabilities in cloud, IT automation, and DevSecOps through acquisitions like Axcelinno.
