From LLC filing to true owner.

A county filing says "GEP XII Roundtree LLC." Who is that? Atrium's entity resolution engine maps that LLC to Greystar — and shows you every other property Greystar owns, every loan they carry, and every entity in their corporate structure. 4.2 million entity relationships, resolved automatically.

Resolve every entity behind every filing.

County filings are full of LLCs and SPEs. Atrium's entity resolution engine connects them to the real companies, funds, and institutions behind the names.

1

LLC to parent company

County filings list SPEs and LLCs, not the firms behind them. Atrium resolves these entities using name patterns, registered agent data, SEC filings, and machine learning — connecting "BMF IV 2021 Roundtree LLC" to Bridge Investment Group.

2

Ownership chain visualization

See the full corporate tree: SPE → fund → adviser → parent company. Understand who truly controls a property and how entities roll up through holding structures.

3

Borrower portfolio rollup

Once entities are resolved, you can see every property a borrower owns across the country — even when they use different LLCs in every county. Total exposure, not just what's in one filing.

4

Lender entity matching

"CBRE MULTIFAMILY CAPITAL INC" in a county filing is Fannie Mae DUS. "WILMINGTON SVG FUND SOCIETY F" is WSFS Bank. We resolve thousands of lender name variations to the actual institutions.

5

Cross-reference matching

Atrium matches entities across county recordings, FDIC call reports, SEC adviser filings, CMBS tapes, and insurance schedules. The same company appears differently in every source; we reconcile them.

6

Continuous resolution

Entity resolution isn't a one-time batch job. New filings arrive daily, and our engine continuously resolves new LLCs, updates ownership chains, and catches entity changes as they happen.

How teams use entity resolution.

From portfolio diligence to counterparty risk, entity resolution powers the answers that matter.

1

See a borrower's full portfolio

Don't just see the one property in front of you — see every property the borrower owns across the country. Identify cross-collateralization risk, total leverage, and portfolio-wide distress signals.

2

Identify the true lender

County recordings list originators, not holders. A loan originated by "KEY BANK NA" may be held by Fannie Mae. Atrium resolves who actually holds the loan today.

3

Track fund-level exposure

Private equity firms use different SPEs for every deal. Atrium connects them — so you can see Blackstone's total CRE exposure across hundreds of LLCs and fund vehicles.

4

Resolve counterparties for diligence

Before extending credit, see the full entity tree of your counterparty. Identify related entities, shared guarantors, and hidden exposures across their corporate structure.

Real-World Example
