The deal with Blackink IT expands KSM’s Intelligent Technology Services Group and broadens KSM’s technology offerings by combining managed IT services with automation, analytics, and human expertise to create a more proactive, insight-driven support model, the accounting firm says.

“Technology has become central to nearly every business decision our clients make,” Tim Cook, CEO and president of KSM, said in a statement on Nov. 2. “We’re excited to welcome the Blackink IT team to KSM as we continue expanding our technology advisory capabilities. Together, we’ll bring strategy, infrastructure, data, AI, automation, and managed intelligence into one coordinated approach that helps clients align technology with their business goals.”
Founded in 1993, Blackink IT is an award-winning MSP, serving as a long-term strategic technology partner for its clients. As an MSP, Blackink IT provides ongoing cybersecurity, physical and cloud infrastructure, end-user support, systems management, and strategic operational IT support.
Doug Allgood, president and CEO of Blackink IT, will lead managed intelligence services at KSM.
“When we began thinking about Blackink IT’s next chapter, finding the right cultural fit was every bit as important as finding the right strategic fit,” Allgood said in a statement. “KSM shares our people-first mindset, our commitment to clients, and our long-term vision for growth. Joining KSM gives our team access to expanded career opportunities and additional expertise while allowing us to continue delivering the responsive, high-touch service our clients know and trust.”
Over the coming months, Blackink IT will transition to the KSM brand.
