Dataflow Management is a privately held advisory firm, founded in 1998 and run as a full-time practice since 2002. We work in two disciplines that most firms keep apart: the technology that runs an organization, and the real estate and facilities that house it. The range belongs to the firm. The depth belongs to its principal, Tom Marsh, whose own career across both runs back more than three decades.
We are independent in the way that matters to a client paying for judgment. We hold no vendor relationships, take no commissions, and resell no hardware or software. The recommendation is the only thing we have to defend, and that is precisely why clients pay us for it.
What makes the advice worth paying for is that it is not only advice. Tom built and ran these environments inside the companies he worked for, and he brings that operating experience to clients without the vendor ties.
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.
The firm is based in Andover, Massachusetts, and has worked across the Americas, EMEA, and APAC. From 2007 through early 2026 it ran a dedicated APAC base in Hong Kong.
