Shopping for an apartment should feel like shopping online. Peek is building the platform that makes it so.
PEEK / The leasing platform that turns every apartment listing into a self-service storefront - tour, decide, and lease online.
In most of American life, the transaction moved online a decade ago. Groceries, cars, mortgages, furniture - all buyable from a couch. Renting an apartment stubbornly did not. Prospects still called during business hours, waited for a leasing agent, and drove across town to walk a staged model unit that was not the one for rent. Peek, a New York proptech company founded in 2019, was built to close that gap.
Peek is an AI-powered leasing platform for multifamily property owners and operators. Its pitch is direct: let renters tour and lease apartments online the way they buy anything else. The company does this with unit-level 3D tours of the exact available apartment, self-guided in-person tours renters can take on their own time, a conversational AI leasing assistant that answers inbound leads instantly, and analytics that show operators how prospects move from a first click to a signed lease.
The founding insight was not "build 3D tours." It was a question about experience. "We didn't necessarily start with interactive 3D tours - we started with 'how do we bring the e-commerce experience to finding a home?'" co-founder and CEO Austin Lo has said. The tours came second. The problem came first.
Every day an apartment sits empty is revenue that never comes back. Multiply that across a portfolio of thousands of units and vacancy loss becomes one of the largest, quietest line items an operator carries.
The traditional leasing funnel leaks at every stage. A renter finds a listing, but the only visuals are a marketing gallery of a model unit. They inquire, but the reply arrives hours later - after interest has cooled. They schedule a tour, but only during staffed hours, and only for units an agent can walk them to. Each friction point is a place a prospect drops out and a unit stays dark.
What Peek attacks
Peek's platform is engineered to shorten the leasing cycle: reduce vacant days, increase sight-unseen leases, and give leasing teams leverage instead of more work. Operators using it report up to 30% fewer vacant days and roughly 3x more prospect tours than legacy 3D-tour platforms - and the company cites a 3.5x lift in leasing productivity alongside a 22% reduction in vacancy loss.
A full-stack conversion engine that combines unit-level 3D tours, self-guided tours, the AI leasing assistant, automated content creation, and renter-behavior analytics to move prospects from interest to signed lease.
Unit-level 3D tours and virtual storefronts that let prospects walk the actual available apartment online - driving about 3x engagement over legacy tour platforms.
On-demand, self-service in-person tours renters take on their own time, freeing leasing teams and keeping the funnel moving after hours.
A conversational AI lead assistant that replies to inbound renters instantly - with a 3D tour of the unit - so prospects explore while interest is high.
Tracks a property's visibility across large language models like ChatGPT and surfaces insights to improve how AI assistants represent the community.
Reporting and prospect analytics that give operators clear visibility into tour-to-lease conversion and overall leasing performance.
"The entire process of finding a home was ripe for an e-commerce disruption."
Virtual tours are not new. Matterport and a wave of legacy 3D-tour vendors made the walkthrough a marketing staple years ago. Peek's difference is where it points the technology.
Legacy tours were built to market a building - a polished flythrough of a model unit meant to make a property look good. Peek builds tours of the specific apartment that is actually available, and wraps them in the machinery of conversion: instant AI lead response, self-guided touring, and analytics that tell an operator which units are stalling and why. The tour stops being a brochure and becomes a checkout aisle.
An outsider's read on the market
Austin Lo came to real estate from finance - a former Nomura volatility trader and investor at J. Goldman & Co. - and only later earned a New York real estate license, working the field for six months before building Peek. He frames that outside vantage as an asset: solve the customer's real problem first, then choose the technology; treat every operator's business model as distinct; and expect adoption to move through patient pilots rather than big-bang rollouts.
That philosophy positions Peek in the fast-moving multifamily proptech and AI-leasing category - alongside self-guided touring and AI-leasing tools such as Funnel, Knock, EliseAI, and LeaseHawk - with a distinct wager: that the unit-level tour, not the chatbot or the model-unit flythrough, is the piece renters actually need to say yes.
Peek sells to multifamily owners, operators, and developers - typically mid-market to enterprise - and its platform spans a portfolio in the hundreds of thousands of units. Named operators include some of the largest names in American residential real estate:
Peek is a B2B SaaS company. It sells subscription software to property operators, with pricing tied to portfolio size and the mix of products deployed, and it integrates with property-management systems (PMS) and marketing platforms. The value proposition is framed around ROI: fewer vacant days, faster lease-ups, and higher leasing-team productivity - a language of return that enterprise operators buy.
Austin Lo and Chris Kostoulas launch Peek to bring an e-commerce experience to finding a home.
The product centers on virtual storefronts that let renters walk the actual available unit online.
AI self-guided tours let renters view units on their own time, off the leasing office's clock.
Conversational AI begins replying to inbound leads instantly - with a 3D tour attached.

Peek has paired product with distribution. A partnership with Apartment List expanded access to unit-level 3D tours across a renter marketplace, and a strategic tie-up with Livly embeds Peek self-guided touring inside the Livly app for a branded, self-service leasing experience. Its Series A backer Moneta Ventures now holds a board seat.
