Openigloo

A broken heater, a silent landlord, and a very good idea

Here is a fact about renting an apartment in New York City that everyone accepts and nobody likes: the landlord knows everything about the building, and you know essentially nothing until the day you move in and the heat doesn't work. This is what economists would politely call information asymmetry, and what Allia Mohamed experienced as a cold first winter. Her early NYC apartment had a heater that broke each season and a landlord who rarely answered maintenance requests. When she went looking for the next place, she wanted to research the building and the person who owned it. The resources to do that did not really exist.

So in 2020, Mohamed and co-founder Srujan Routhu built them. Openigloo started as an anonymous review site - Yelp, but pointed at landlords and buildings instead of restaurants. Renters could write what they actually experienced, read what others had, and the whole thing would be cross-referenced against the public data that technically exists but that almost nobody reads: housing violations, litigation history, bedbug reports. The pitch is simple enough to fit on a subway ad. The execution is the hard part, and the interesting part.

The market, quantified

Those numbers describe a genuinely large problem. Roughly half of New York's housing stock is rent-stabilized, which is supposed to be a protection. The catch is that about 35% of Openigloo's users report not knowing whether their own apartment is stabilized. A protection you don't know you have is not much of a protection, and this gap is precisely the thing Openigloo turned into a product.

One renter, using Openigloo's crowdsourced rent-history data, discovered their apartment should have been stabilized and watched a $3,400 monthly rent drop to $1,400. That is $24,000 a year. It is the kind of number that turns an app from a nice-to-have into something you tell your friends about, which is more or less how a review platform grows to three million people.

The renter's toolkit

The critics asked for a seat at the table

There is a version of this story where Openigloo stays a review site forever, landlords resent it, and the two sides glare at each other across the internet. That is not what happened. Landlords, unsurprisingly, did not love being reviewed. But then some of them asked whether they could respond. That request - a company's harshest audience asking to participate - turned out to be a business.

The result is IglooIQ, a data-driven leasing platform for landlords. It handles listing agreements, rental applications, income and credit verification, and a rent-guarantee program, and it hands owners something more valuable than any of that: actionable tenant feedback about what is actually wrong with their buildings. Openigloo charges landlords for placements - typically around half a month's rent - which is how a free consumer app pays for itself.

When feedback becomes a growth strategy

Silverstein Properties adopted IglooIQ for amenitized Manhattan buildings, used the review data to make staffing improvements, and now advertises its ratings publicly. At one property, tenant retention climbed to roughly 85%, up from under 70% before the pandemic. The chart below is a simple illustration of the shift.

Small round, large ambition

Openigloo raised a seed round that closed on September 29, 2022. The specific amount has not been publicly disclosed - so treat any figure you see elsewhere as approximate - but the backer list is a mix of proptech and generalist investors.

From review site to rental platform

• 2020
  Openigloo launches as an anonymous landlord and building review site, founded by Allia Mohamed and Srujan Routhu in Brooklyn.
• 2022 · SEP
  Seed round closes; the company begins building out city-data integrations and stabilization tools.
• ~2022 onward
  Landlords ask to respond to reviews - the seed of IglooIQ, the landlord-facing leasing product.
• 2025 · AUG
  The Real Deal profiles the push to win over landlords; IglooIQ working with 5,000+ units.
• 2026 · JAN
  NYC's Rent Transparency Act takes effect; Openigloo's stabilization map is positioned to help renters act on it.

Who else is in the building

The listings incumbents - StreetEasy, Zillow, Apartments.com - own the search box but not the trust layer. Review-first players like WhoseYourLandlord and Rent Logic share Openigloo's instinct. And the raw material, NYC's HPD and ACRIS data portals, is free and public but effectively unreadable. Openigloo's wager is that combining crowdsourced reviews with humanized public data, and then charging the landlords, is a more durable position than any of those on its own.

Five things worth knowing

• The name evokes an igloo - a home - opened up and made transparent.
• The founding story is literally a heater that broke every winter and a landlord who wouldn't call back.
• About 35% of users aren't sure if their own apartment is rent-stabilized.
• The company's business model was effectively suggested by the landlords it once only critiqued.
• One renter's rent fell from $3,400 to $1,400 a month after the data revealed an overcharge.
