IBM Consulting vs Coherent Solutions: overview

IBM Consulting

IBM Consulting traces to 1991 and is headquartered in Armonk, New York, with roughly 160,000 employees globally. Its generative AI advisory work draws heavily on IBM's own watsonx platform and decades of enterprise technology relationships. That platform tie-in is a genuine advantage for clients already invested in IBM infrastructure, and a real constraint for clients who aren't, a trade-off worth weighing before any generative AI shortlist gets built.

Coherent Solutions

Coherent Solutions was founded in 1995 by Igor Epshteyn in Minneapolis, Minnesota, and reported roughly 2,200 employees as of 2023. The company runs offshore development offices across Belarus, Bulgaria, Moldova, Mexico, Lithuania, Ukraine, Romania, Georgia, and Poland. Its core business is software product development and consulting, with generative AI consulting delivered as part of that established practice rather than marketed as a separate, dedicated AI unit.
