IQVIA Reg Intel knows requirements. Rhizome shows you how to meet them.
IQVIA Reg Intel is a requirements library covering 110+ countries, regions, and international organizations (more geographies than we cover, and we'll say so plainly). Rhizome goes the other direction: everything underneath the requirement, so your team can decide what to actually do, with each claim cited to the exact passage.
How they differ
Breadth vs depth — and they win breadth. Let's put the honest part first. IQVIA RI covers regulatory requirements for drugs, biologics, devices and IVDs across 110+ countries, regions, and international organizations, with cross-country comparison tables, alerts when a matching document changes, and local expert summaries. If your job is knowing the current requirement in every market you file into, that reach is real and we don't match it.
What a requirements library can't do is tell you the right course of action. It holds the rule; it doesn't hold the summary basis of approval packages, the discipline reviews, the trial protocols, or the published literature the reviewers leaned on, nor the long tail of odd documents authorities publish with no obvious home. So the catalog hands your RA team the requirement and leaves them to supply the judgment alone. That's the moment the work gets hard: everyone in the room knows what's required, and the argument is about what to do, and the evidence that would settle it is sitting in documents the library doesn't carry.
Rhizome is built for exactly that layer: >45M documents across >75 health-authority databases in >12 markets (as of August 2026) — review packages, protocols, letters, enforcement, and literature alongside the guidances — so “how did the last thirty programs handle this” is an answerable question, with every claim opening to the passage it came from. You don't walk into an agency meeting quoting the rule. You walk in showing what the agency accepted before.
Search vs ask. IQVIA RI is a search-and-filter surface: query, narrow, export what matched, synthesize by hand. Rhizome inverts that: ask in plain language, and the agents run the fan-out across hundreds of sources, sometimes thousands, returning one synthesized, passage-cited answer. Users running both tell us which one they reach for first.
How you buy. IQVIA RI is an enterprise subscription: quotes, contracts, onboarding. Rhizome is self-serve with a free tier and published pricing: ask a real question from your program today and check the citations before anyone talks to procurement.
When Rhizome is the better choice
When IQVIA Regulatory Intelligence is the better choice
Plenty of teams run both, and that's the arrangement we'd recommend: their catalog for what's required everywhere, Rhizome for the evidence behind what to do about it.
