Reef is a real estate underwriting software and investment committee memo platform, an underwrite-to-IC operating system for real estate finance teams. It turns offering memorandums, rent rolls, ARGUS files, Excel models, broker assumptions, market benchmarks, and property tax data into a built underwriting model and an IC-ready memo.
The platform carries a deal from raw intake to committee output in one governed workspace: unified intake of OMs, rent rolls, ARGUS, and financials; an underwriting engine that generates the working model with visible revisions; benchmarking with market and property tax context built in; early risk flagging for tenant concentration, occupancy dependence, rent anomalies, and cross-document inconsistencies; and IC memo drafting and proofing from the same source of truth.
Reef also supports firm Excel model templates, so output stays aligned with how each team already underwrites, and keeps institutional memory attached to every deal, with version history, a searchable knowledge graph of prior deals and assumptions, and reusable decision logic. It is used by acquisitions, asset management, investment, and capital markets teams, private equity firms, lenders, REITs, and family offices, and claims a 70 percent time saving on IC memo production.
