Frequently asked questions
Reltio scores D on Supergood's API Report Card. Reltio documents an extensive REST API for its MDM platform: entity CRUD, relations, reference data, bulk load and export, workflow, plus Kafka event streaming. It is enterprise software; calls run against your licensed tenant, and the gateway returns 429s past licensed API concurrency.
Without a usable official API, teams fall back on manual exports, file drops, or one-off vendor integrations. The other option is an unofficial API layer like Supergood that automates the authenticated web app directly. Site terms may apply to any integration approach, and how they apply is a determination each team makes for itself.
Reltio is a Redwood City, California-headquartered cloud-native master data management (MDM) and 'context intelligence' vendor founded in 2011 by Manish Sood (ex-Siperian/Informatica) and Anastasia Zamyshlyaeva.
Primary vertical: misc (cross-industry enterprise MDM). A pharmaceutical company stands up Reltio Connected Data Platform to unify HCP (healthcare professional) and HCO (healthcare organization) master data across CRM (Veeva, Salesforce), commercial data providers (IQVIA, Symphony, Definitive Healthcare), claims and Rx data, internal master files, and event/engagement systems.
High in its niche. Reltio is consistently named a Leader in the Gartner Magic Quadrant for Master Data Management Solutions alongside Informatica, Stibo Systems, Profisee, and Semarchy, and is one of the half-dozen MDM platforms a Global 2000 CDO will always shortlist.
Reltio is the system of record for an enterprise's most important entity data, who its customers and patients are, which physicians and hospitals it sells to, what products and SKUs exist, who its suppliers are, and how those entities are related.
Founded in 2011 as one of the first cloud-native, multi-tenant MDM platforms, well ahead of Informatica's cloud transition.
Supergood's grades measure one thing: can a customer's engineering team get their own data out programmatically? Supergood checks six things (whether a real API exists, how access is gated, data coverage, auth quality, docs and developer experience, and stability) and rolls them into a letter grade. Supergood re-verifies grades, and they only move on evidence.
Reltio scores GOOD on MCP availability. Reltio publishes an official open source MCP server (Developer Edition) under its reltio-ai GitHub organization, with setup and Claude Desktop connection instructions and commits within the last six months. It exposes entity search, matching, merge, and data model tools against Reltio tenants.
Yes. Reltio publishes an official MCP server, so MCP clients like Claude, Cursor, and Codex can connect to it directly. Setup instructions are in the vendor's documentation.
