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.
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. The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.

Properties that don't map to a standard resource type
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.

This is an independent, third-party profile of Concord Data Systems, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.
The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.
Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
