History
InterSystems was founded in 1978 by Phillip T. (Terry) Ragon, its current CEO. The firm was one of the vendors of M-technology (aka MUMPS) systems, with a product called ISM-11 (an DSM-11 clone) for the DEC PDP-11 . Over the years, it acquired several other MUMPS implementations: DTM from Data Tree (1993); DSM from Digital (1995); and MSM from Micronetics (1998); making InterSystems the dominant M technology vendor.
The firm eventually started combining features from these products into one they called OpenM, then consolidated the technologies into a product, Caché, in 1997. Caché offered several new important features, not available in MUMPS offerings, including support for web, object-oriented development and SQL access to the database.

Why this record matters
“InterSystems” is worth following because a concise public description often conceals a longer documentary argument. Here, InterSystems and company provides the most credible route into that argument.
Chronology, provenance and viewpoint should be read together before a broad social or political interpretation is accepted. The source revision retrieved here is dated Jun 15, 2026. The linked authority identifier is Q948399. VIAF identifies the subject as 156440615. 3 of 3 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank. The first chronological checks are 2023, 2024, 1978 and 1993.
Official terminology may obscure informal participation, dissent or communities documented only indirectly. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
