Real Estate and Construction Startups funded by Y Combinator (YC) 2026

EquipmentShare delivers cloud solutions for the construction industry. We provide a better equipment rental experience, fleet tracking software and hardware security solutions to help contractors work smarter.

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.

Alloovium is the document intelligence layer for construction 🏗️ It reads every document and piece of data on a project (contracts, specs, drawings, compliance records, conversations), turning them into answers you can trust and actions with real value: every answer cites its exact source sentence, paperwork is checked clause by clause against the builder's own Integrated Management System, and nothing AI-drafted moves without a human sign-off, with it all compliant by default.

Vestris automates title processing end-to-end, from contract to close, so title shops can close more deals with fewer processors. Title insurance has famously high margins, but slow, manual processing is a constant pain — especially in today's bleeding housing market.

FlowManual is the all-in-one AI estimating, bidding, and purchasing platform for both general and MEP construction contractors. Built by two engineers and Harvard dropouts, FlowManual automates the buying process during pre-construction. With FlowManual, specialty contractors win more work while general contractors deliver at higher standards.

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 Much of the software used across the real estate industry is outdated.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.

Home services companies lose money on missed calls and idle techs. When the phone rings during a job and nobody picks up, that lead goes to a competitor and the trucks already on the road sit half-booked because dispatch can't keep the schedule tight. CentralComs fixes this with AI agents that answer every call, route each job to the right technician, and keep the calendar full. They handle intake, dispatch, and customer updates end to end working inside ServiceTitan, Housecall Pro, and Jobber so no lead slips through and no truck runs empty. Capture every call. Book every tech. Never miss a job.

AquaShield protects large real estate portfolios against water damage (losses of up to hundreds of millions per year).

Rudus is an AI-powered takeoff and estimation platform enabling concrete contractors to win 3x more projects yearly. It automatically identifies every concrete structure like footings, walls, columns, and slabs on plans, eliminating the manual work and reducing estimation time by 70%. Concrete is the most-used material on earth after water, and demand is surging with the AI infrastructure boom.

PLAN0 is building the Bloomberg of construction for real estate developers, investors, and general contractors — $30B of projects are already running through the platform. We analyze architectural plans using vision models to generate detailed cost estimates and analytics in minutes. Through industry partnerships, the platform also aggregates historical and real-time project data across all major geographies to power ML-driven analytics, decomposing costs into market-observable factors and creating an agentic layer for cost optimization.

Foreman is the all-in-one AI-powered project management platform built for construction contractors and the trade industry. Today, contractors run complex businesses on a patchwork of tools that were never designed for construction — estimates in spreadsheets, plans in email, proposals copy-pasted from old Word docs, photos scattered across phones. Nothing talks to anything else, and the admin work never stops. Foreman replaces that patchwork with a single platform that manages the full lifecycle of a construction job, from first estimate to final invoice. Contractors upload plans, photos, or a project description, and Foreman's AI instantly generates structured takeoffs, scoped estimates, and professional proposals — in minutes, not hours. From there, every customer record, document, permit, photo, change order, and conversation lives in one place, organized around the job. The result: contractors spend less time buried in admin and more time building. They bid faster, manage jobs with less chaos, and close projects cleanly — without duct-taping five tools together to do it.

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.

We've built an AI property manager that automates maintenance requests, handling tenant calls and messages 24/7, following up by chasing contractors and resolving issues.

We help construction teams eliminate rework, delays, and drawing confusion before construction starts.
We analyze PDF plans, detect clashes and inconsistencies across disciplines, and create draft RFIs so teams can resolve issues early. This saves construction companies hundreds of hours and millions of dollars. What we do: - Automatically detect clashes, missing information, and drawing mismatches - Align architectural, structural, and MEP plans so everything matches across sheets - Generate draft RFIs from issues we find - Replace long page-turn meetings with instant drawing analysis - Reduce rework and prevent schedule delays before boots hit the ground We integrate with:
Procore, Autodesk, email, and the tools teams already use Teams use us to: - Save hundreds of thousands to millions of dollars per project - Catch design and coordination issues early - Reduce RFIs and prevent field fixes - Keep projects on schedule with fewer surprises Contact us at founders@helonic.com

Structured AI is the most advanced AI-powered QA/QC platform for drawing packages, working across both PDF drawings and native Revit models. Architects and engineers use our platform to make every drawing set leave the office with certainty. Our AI agents learn your firm's standards, apply the relevant codes, and read every page of a set, then return a clear list of what's wrong, where it sits, and how to fix it. Run compliance reviews across thousands of pages in minutes, chat with your drawings for sourced answers, build custom checks in plain English, compare versions, overlay disciplines, and close out comments - all within a single platform, with a full audit trail on every finding. For decades, the last line of defense on a drawing set has been a red pen at the end of a deadline week. But buildings have outgrown the red pen. A modern set runs thousands of drawings, and the errors hiding between them threaten quality and safety, not just cost. What manual review misses resurfaces as RFIs, change orders, and field rework, paid for in time, margin, and reputation. Structured AI catches those errors before they leave the office, capturing the judgment of your best reviewer once and applying it everywhere. Better drawings build a better world. #GetStructured

For property operators, Wayline instantly replaces robo-menus and call centers, while centralizing and scaling back-office teams.

We use AI to help electricians speed up the time it takes to submit a competitive bid to a job. We do this by scanning complex CAD drawings and 10X-ing the time it takes to estimate a job. This involves using vision models to read and count complex symbols in large PDFs, which typically take hours (sometimes days) to do precisely. Every missed symbol can cost thousands, and our AI can count to 99% accuracy.

Opusense AI automates field report writing for construction field inspectors. Instead of typing up notes at the end of the day, inspectors can now walk a site, speak observations aloud, snap photos, and let our AI assistant generate a detailed, organized report on-site and in real time. Combined, the founding team has over 15 years in the construction industry. Writing up these field reports used to take up at least 20% of the week. With Opusense, we cut that time by 5x. Our team combines deep construction experience with technical expertise, Roya has a PhD in civil engineering, and Michael has worked at multiple construction tech startups. Why hasn’t this been done before? Construction is slow to adopt new tech, and reporting is messy, photos, voice notes, and field notes all live in silos. Turning that into a clear, structured report requires real insight into how inspectors work and what clients need. Only now, with advances in AI, can we process unstructured data adequately to generate high-quality reports in real time. The opportunity is massive. Every inspection firm and contractor is struggling with documentation. Manual reports slow them down, create inconsistencies, and delay handoffs. We believe AI can do this better, and Opusense is proving it.

Bild AI automates Division 8 estimating — doors, frames, and hardware — end to end. Bild AI reads blueprints and specs, generates opening (door) schedules automatically, prices the bid, and exports it directly into the ERPs Division 8 shops already run on, including Comsense, Avaware, and ProTech. Division 8 estimating is the brutal trifecta of nitty-gritty details, where typos cost hundreds of thousands, and timelines are tight. Thousands of pages of specs, hardware sets cross-referenced by hand, and a single missed opening that can sink a bid's margin. Bild AI collapses days of takeoff into hours, and clients have bid 50% more with smaller estimating teams. Backed by Khosla Ventures (YC W25).

City building departments are understaffed and overworked. Meanwhile, builders lobby to remove power from building departments. Because building departments are usually the only profitable/self-sustaining branch of a local government, this is problematic. Permitify allows city build-plan reviewers to 10x their productivity covering the labor shortage, reducing the time required to issue a building permit, and allowing the city government's only profitable branch to stay intact.

ArchiLabs is building the data center project OS.

We are building workflows to help developers go from finding and closing development sites to getting a building permit faster. PermitPortal accelerates the most critical parts of the pre-construction phase: finding the right sites, understanding entitlements and navigating local development sentiment.

Karmen is an AI scheduling assistant for construction. Karmen builds your baseline schedules from project documents, and updates them as your project evolves, saving you time and potential delays.

Fresco is an AI-powered takeoff and estimating for Division 8 construction (doors, frames, and hardware). Estimating Division 8 has always been brutally manual: flipping through hundreds of pages of specs, cross-referencing hardware sets, and building out schedules by hand. A single missed door or misread hardware group can kill a bid's margin. Fresco automates the entire takeoff process with 99% accuracy, cutting the time estimators spend on takeoffs by 70%. We've processed 3,000+ takeoffs for general contractors and Division 8 subs, and we're becoming the system of record for how this trade gets estimated. Division 8 is our beachhead: it's complex enough that AI creates massive value, and siloed enough that the incumbents haven't solved it. We're starting here and expanding across the spec trades.
