Managing Agents
live23 firms tracked
Firms that run day-to-day operations: collect common charges, hire contractors, file LL11. The only category where we have full portfolio data.
Browse the directory →VENDOR DIRECTORY
Every category that touches your building.
Beyond managing agents, six other vendor categories shape how your building runs: engineers, law firms, contractors, insurers, auditors, and accountants. Across the NYC condo / co-op portfolio, the same firm names appear repeatedly. We track the patterns.
SIX CATEGORIES
Where coverage is, and where it's coming.
Managing agents are fully tracked. The other five categories are at varying stages of build. Engineers ship next (LL11 filer data already extracted); law firms and contractors follow.

WHY THIS MATTERS
The vendor layer is where the money actually moves.
A typical 150-unit building spends $4-6M per year on operations. Roughly 60% of that goes to the vendor layer: contractors, engineers, insurance, legal, accounting. The managing agent picks most of those vendors. Patterns in who picks whom — and who refers business to whom — are the heart of the extraction structure documented in /issues/.
For board members or unit owners trying to evaluate whether their vendor mix is normal or compromised, the directory is the comparative layer. For journalists, it's where the recurring patterns live.
