Dataflow Management is a privately held consulting practice, founded in 1998 and run by its principal, Tom Marsh, as his full-time work since 2002. It covers two disciplines that most firms keep apart: the technology that runs an organization, and the real estate and facilities that carry it. It is principal-led on purpose. The person who leads the engagement is the person who ran this infrastructure from the inside, at Hitachi and then Macromedia, before he ever advised on it.
The judgment comes from operating, not from a career of advising. Tom built and ran these environments inside the companies he worked for, and clients get that experience without the vendor ties. We hold no vendor relationships, take no commissions, and resell nothing, so the only interest in the room is the client's.
Our clients include firms in technology, life sciences, higher education and research, manufacturing, insurance, law, construction, and private equity. The people who bring us in are usually CFOs, CIOs, COOs, and the heads of real estate, workplace, or operations who answer for the result. We do not name them, because confidentiality is part of what they are buying.
Dataflow is an SBA-certified Service-Disabled Veteran-Owned Small Business and holds a Department of Defense CAGE code (CAGE 9LYE2). The Commonwealth of Massachusetts recognizes the SBA certification through its Supplier Diversity Office and separately certifies the firm as a small business under its Small Business Purchasing Program. Public-sector buyers and supplier diversity programs can engage the firm at the federal or state level.
The firm is based in Andover, Massachusetts, and has worked across the Americas, EMEA, and APAC. It ran a dedicated APAC base in Hong Kong from 2007 to 2026, and APAC engagements now run from Andover like the rest of the practice.
