Thomas L. Marsh
More than three decades working where the technology of an organization meets the buildings and people that depend on both. Founder and principal of Dataflow Management.
Two disciplines, on purpose.
Tom works across two disciplines deliberately: the technology that runs an organization, and the real estate and facilities that house it. Most of his career has lived on the boundary between them, where what the systems want runs into what the building, the lease, or the regulator will allow. Dataflow is built around exactly that pair, one firm with a technology practice and a real estate and facilities practice, led by one principal.
He describes himself as ten miles wide and a mile deep rather than a mile wide and ten miles deep. The width is real, and so is the depth. The breadth is what lets him see a problem whole, and the depth is what gets it built and proven.
The current shape of the practice is a continuation of the career, not a pivot. The first decade was inside semiconductor manufacturing, where the line between technology and physical plant does not exist. The second was inside two software companies whose growth was paced by their data centers and their offices. The third has been on the outside, advising firms that face the same problems from a different seat.
A short version of a long story.
Tom's career began at Medical and Technical Research Associates, a Boston-area contract research organization, supporting laboratory and clinical research infrastructure under FDA regulation. He then joined the global Hitachi business, working across Hitachi Semiconductor America, later divested into Renesas and Elpida, Hitachi America, and Hitachi Canada. The work was field-office infrastructure and managed voice for divisions whose products ranged from memory chips to construction equipment to broadcast television, all of them dependent on factories, fabs, and offices that had to run on a global clock.
He moved next to Allaire, which was acquired by Macromedia during his tenure. At Macromedia he served as Senior Director of Global Enterprise Engineering, with end-to-end accountability for global infrastructure during the company's fastest growth. The most visible piece of that work was the platform behind global software distribution, which delivered content at internet scale and stayed continuously available at roughly 100 million downloads a week, a volume that was unprecedented for 2001, well before today's content-delivery networks existed. The less visible piece was the steady work of running data centers, choosing real estate, and holding the company's costs in line as it scaled. Macromedia was also Nortel's first IP-phone customer, an early enterprise move to voice over IP.
Dataflow Management was founded in 1998, and Tom turned it into a full-time consulting practice in 2002, after Macromedia. The firm is based in Andover, Massachusetts, and has worked across the Americas, EMEA, and APAC, with a dedicated APAC base in Hong Kong from 2007 through early 2026. Engagements have spanned technology, life sciences, higher education and research, manufacturing, insurance, law, construction, and private equity.
