Real Estate Startups funded by Y Combinator (YC) 2026

We use AI agents to manage short-term rental properties by running operations completely autonomously. We cut traditional human management fees in half so owners take home 20% to 30% more revenue. And we operate with near-zero boots-on-the-ground so we can scale nationwide with software margins and at venture speed in a traditionally physical industry.

We build centimeter-accurate 3D maps of underground utilities to help construction contractors dig safer and faster. With underground intelligence, contractors can avoid dangerous utility strikes and costly project delays.

RealPact builds AI agents that handle the paperwork behind real estate transactions. They find property records like deeds, tax records, permits, parcel data, and MLS information, then use that data to fill out contracts, organize documents, track deadlines, and help brokerages close deals faster. We are starting by automating transactions and will expand into other parts of brokerage operations. Much of the software used across the real estate industry is outdated. With today’s advances in AI, we can build agents that handle this operational work and create modern software around how brokerages actually work. We currently sell to brokerages in New Hampshire and are expanding quickly.

At AutoSitu, we’re building the AI operating system for the built world—coordinated AI agents that work across development, design, review, and construction. Our agents analyze complex plans, requirements, and project documentation in minutes—surfacing critical issues, doing the heavy lifting, and escalating the decisions that require human expertise. From site feasibility and entitlement risk to QA/QC, code compliance, constructability, quantity takeoff, and scope analysis, AutoSitu helps cities, architects, engineers, developers, and construction teams identify problems earlier and move projects forward with greater speed and confidence. We serve as a strategic AI partner to forward-thinking public agencies and AEC organizations across the country and are backed by Y Combinator (W26).

Goldbridge is building the financial operating system for the largest asset class in the world – real estate. More than $1T in rent flows through landlord bank accounts annually, with roughly a quarter locked in idle reserves and security deposits – and billions more leaking from unnecessary property expenses. And with $2.5T in real estate loans about to mature in 2027/28, property owners are desperate to boost their income ASAP. Goldbridge solves this problem by creating the first AI-powered banking platform for real estate owners. We are backed by Y Combinator and other world-class investors, and our founding team includes a 2x YC founder, former White House advisor, and 100-unit real estate owner/operator with deep industry expertise. Come help us redefine the future of real estate.

Digitalcarbon transforms ordinary images and videos into interactive, photorealistic 3D environments. Our technology can take photos from any device and render 3D scenes at more than 100 frames per second on everyday devices. The founders were the first and second hires at a previous YC company AssemblyAI, and have more than 8 years of experience building AI models.

Digitalcarbon fixes that, eliminating the need for specialized equipment and dramatically accelerating the rendering process. Our technology enables applications across various industries: * Real estate: Creating virtual property tours that feel remarkably lifelike * E-commerce: Providing interactive 3D product visualizations to boost consumer experience * Tourism: Helping tourist businesses attract more travelers with immersive virtual previews * Drone mapping and inspection: Enhancing aerial surveys and structural assessments with detailed 3D models Think Unreal Engine meets Matterport with no hardware, but faster, editable, and more accessible for businesses of all sizes.

The pandemic reduced office use nationwide by 50%, and tenants have been left to deal with highly inflexible, long term lease agreements that don’t fit today’s office use patterns.

Cash Flow Portal is an investment management platform for real estate. We launched 5 months ago, and we have 6-figure ARR, growing 50% month over month, with 300 syndicators and 3,000 investors.

Lofty is a marketplace that let's anyone sell a house to investors online. Instead of the typical real estate transaction where one seller sells to one buyer, Lofty is much more flexible. Sellers fractionalize their equity ownership in the property into smaller units, so that anyone can buy a portion for as little as $50, allowing access to one of the best asset classes for people who have previously been locked out. Sellers can also sell a portion of their equity (starting at just 10%) instead of the entire property or create customized HELOC structures. Investors can browse a variety of individual real estate properties ranging from commercial strip malls, a HELOC in someone's house, Airbnbs, to a single-family rental properties, and directly purchase ownership in these properties in under 5 minutes. There is no lockup period. Users can constantly trade these ownerships with others on the marketplace. Investors truly legally own the properties they invested in and co-manage it with other investors through an online governance program. Owners have so far voted on how to handle various repairs, delinquent tenants, the sale of the underlying property, and much more. Lofty never custodies or handles user funds or assets. Through smart-contracts on the blockchain, all transactions are directly peer-to-peer. If we succeed, we'll have built the NASDAQ for real estate and transformed how real estate is bought and sold in the USA.
