Openigloo
“Openigloo built something genuinely useful: verified NYC listings with landlord reviews, rent-stabilized apartment tracking, and transparent building ratings — the kind of hyperlocal rental intelligence that actually helps tenants navigate the city's Byzantine housing market. The cruel irony is that they perfected the art of aggregating and analyzing rental data just as Claude learned to do comparative housing analysis from scratch, and ChatGPT started parsing lease documents and rental regulations without needing a database of 'top-rated buildings' to reference.”
