Concord Data Systems
Concord Data Systems was a telecommunications equipment manufacturer founded in 1979 by Ken Miller (previously Director of Modem Development at Codex) and based in Marlborough, Massachusetts. The company designed and sold high-speed full-duplex dial-up telephone modems for transmitting digital computer data in analog form over the public switched telephone network. As the modem hardware market commoditized, the business pivoted from industrial data communications to the emerging market for network performance management software and was renamed Concord Communications, best known for its eHealth network management suite. Battery Ventures was one of thirteen investors in that company. Concord Communications was acquired by CA (Computer Associates) on 2005-06-07 for approximately $350 million ($330M cash plus roughly $20M of assumed net debt); CA was itself acquired by Broadcom in 2018. Concord Data Systems is therefore a historical, defunct entity: it operates no website, no developer portal, and no API surface today. It is retained in the API Evangelist network as a venture-portfolio lineage record only.
Index entry only — little beyond a description and a link, and nothing machine-readable enough for an agent to act on without a human reading the site first.
Concord Data Systems is tracked in the API Evangelist network. This page is the human-readable profile that sits on top of the machine-readable index we maintain at apis.io.
Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — Concord Data Systems scores 6.8/100 (minimal), with a separate agent-readiness read of 0/100 (human only). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.
Kin Score
This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance.

Concord Data Systems is in the network as a tracked entity. We haven't yet indexed a public API surface for it — when one is published, the artifacts, score, and agent-readiness read will appear here automatically. The source repository is where that profile is built.
