Four people who understand both CRE and data.
Former acquisitions analysts, data pipeline engineers, commercial appraisers, and CRE brokers — not a generic proptech team. Everyone on this team has read a rent roll under deal pressure.
Team Profiles
Rachel Goldberg
From 2016 to 2022, Rachel worked in CRE acquisitions in New York, screening and underwriting middle-market multifamily and mixed-use deals. At every firm, the same bottleneck: rent roll PDFs that wouldn't parse, lease stacks that needed three days of manual abstraction before IC could evaluate the NOI, and OMs that buried the expense growth assumption where no analyst had time to look.
She left acquisitions in 2022 to build Tenantvein — not a platform, not a CRM, not an OM tool. Specifically the data extraction and modeling layer. She built what would have changed how she worked.
Daniel Park
Spent four years building structured data ingestion pipelines at a financial data firm in NYC — processing securities filings, pricing feeds, and event-driven corporate data at scale. At Tenantvein, Daniel leads document processing: the ingestion layer that normalizes rent rolls, leases, and OMs from PDF, Excel, Word, and scanned TIFF into clean, query-ready output regardless of how badly the source was formatted.
Simone Achebe
Simone spent five years in commercial appraisal and ARGUS DCF modeling across office, multifamily, and industrial assets before joining Tenantvein. She owns the underwriting logic — how cap rates are calibrated to submarket and vintage, how DSCR is calculated from live assumptions, how NNN expense structures are classified versus modified gross, and how the platform flags TILR provisions and co-tenancy risk. The output quality standard at Tenantvein is: what an experienced in-house underwriter would have produced after a full read.
James Kowalski
Spent seven years as a CRE broker in the Northeast, covering industrial and mixed-use transactions — which means James has been on both sides of the rent roll conversation: the seller formatting it to obscure the vacancy, and the buyer trying to extract the real numbers under time pressure. At Tenantvein, he sits with each new acquisition team on their first live deal to make sure the output maps cleanly to their IC model and lender submission workflow. He also handles the edge cases — the deals where the source documents are genuinely bad and someone needs to make a judgment call about how to handle it.
