Buildots announced a $130 million funding round on 14 September 2026, led by O.G. Venture Partners, with participation from Lightspeed Venture Partners, Intel Capital, Mohari Ventures, Human Capital, Qumra Capital, Viola Growth, Poalim Equity and the angel investor Avigdor Willenz. The release puts the Tel Aviv company’s total capital raised at $297 million.
The company did not disclose a valuation. Calcalist reported that the round “pushed its valuation to an estimated $1 billion,” against “the approximately $300 million valuation at which it completed its previous $45 million round a year and a half ago” — on those two reported numbers, more than a tripling in about fifteen months. Neither valuation is company-confirmed, and this newsroom has not independently verified either.
What is confirmable, and more interesting than the headline number, is who the release says is using the product.
The Customer List
The announcement names Digital Realty and Intel as owners, and STO Building Group, JE Dunn, Mortenson, Bouygues, HOCHTIEF and Turner Construction among the contractors. That is not a scattering of pilots across a broad market. It is a concentration at the top of the projects that have become the industry’s hardest scheduling problem: data centres, chip fabs, energy infrastructure.
One name appears twice. Intel is listed among the owners using the platform, and Intel Capital is among the investors in this round. That combination — a customer on the cap table — is common in construction technology and is usually the most credible validation an enterprise vendor can point to, though it also means one of the named references is not a disinterested one. Buildcheck’s Series A had the same structure with DPR Construction five days earlier.
The release frames it in those terms directly — “On AI data centers, advanced manufacturing facilities, energy infrastructure and other mission-critical projects, construction has become more complex, timelines are shorter, and more is at stake.” Roy Danon, Buildots’ CEO and co-founder, is quoted saying the shift “was already underway before the AI buildout, but the buildout has poured rocket fuel on it,” and closing with a line the company clearly likes: “The AI era will be built on schedule.”
Set aside the framing and the structural point stands. A hyperscaler data centre is a project where a month of slip is measured in foregone revenue on capital equipment that is depreciating on a schedule of its own, and where the general contractor is frequently running several near-identical builds at once. That is the ideal shape of customer for a system whose whole proposition is that it can tell you, continuously and without asking anyone, what has actually been built against what was planned.
What Buildots Actually Sells
Buildots’ platform converts site imagery into a continuously updated digital model of a project, then compares that model against the schedule and the design. The company’s own site describes the pitch as “Construction intelligence to power your whole operation,” and lists Buildots Field — a workforce, safety and logistics product — and a managed Capture Services offering alongside the core platform.
The comparison step is the product. Progress reporting on a large project is otherwise a human process: superintendents walk, estimate percentages, and report upward through a chain with an institutional incentive to round optimistically. A system that measures the same thing from imagery does not need to be brilliant to be valuable. It needs to be consistent, and it needs to be free of the incentive.
What the Company Reports
The figures below are Buildots’ own, disclosed in the announcement, and have not been independently verified here.
The release says “100+ of the world’s largest firms already use Buildots,” describes “a multi-year streak of 3x annual revenue growth,” and states that “seven-figure, portfolio-wide, multi-year agreements are now the norm for Buildots, not the exception.” Construction Dive reported the same characterisation of contract size on 14 September. Buildots’ site claims projects using the platform have achieved up to a 50% reduction in delays.
The contract-size claim is the one worth holding onto, because it is the one that describes the business rather than the technology. Construction software has historically been sold in seats to project teams. A portfolio-wide, multi-year, seven-figure agreement is bought by someone else entirely — an executive with a capital programme, not a project manager with a budget line. If that is genuinely the norm rather than the exception, the company has changed what it is.
Fifteen Months, and a Different Company
Buildots raised $45 million in a Series D announced on 29 May 2025, led by Qumra Capital, which brought its total to $166 million. This newsroom cited that $166 million figure as recently as our June analysis of AI safety monitoring. Fifteen and a half months later the total is $297 million. On the company’s own two stated totals, this single round is worth roughly four-fifths of everything Buildots had raised before it.
Ziv Kop, Managing Partner at O.G. Venture Partners, is quoted in the release making the investor case in plain terms: “In 20+ years of backing category-defining companies, the pattern is always the same: the winners build the foundational technology layer that everyone else ends up depending on. Buildots is that layer for construction, trained on a volume and quality of site data that nobody else has.”
That last clause — trained on site data nobody else has — is the thesis, and it is the same one being underwritten across the sector.
The Capture Layer Keeps Getting Bought
The pattern is now hard to miss. Procore is paying approximately $845 million for DroneDeploy, a deal whose logic we argued was the acquisition of ground truth rather than of a drone company. OpenSpace has documented 1,000 data centre projects, a milestone that says as much about where construction AI is being deployed as about OpenSpace. Sensera Systems raised $27 million on a bet that the durable value sits in the software layer above its cameras rather than in the cameras.
Buildots’ round is the same wager placed at scale. The strategic question the sector has not yet answered is whether owning capture is a defensible position or a temporary one. Imagery is getting cheaper to collect every year; phones, helmets, fixed cameras and robots all produce it. If capture commoditises, the advantage moves entirely to the comparison layer — the model of what should be there, and the accumulated record of how projects of a given type actually progress. Buildots’ framing, and Kop’s, is that the accumulated record is the asset — the company has been collecting it since 2018. It is a plausible argument. It is not yet a proven one, and nothing in this announcement settles it.
What Is Not Known
Buildots did not disclose a valuation, revenue, customer concentration, or how much of its business the named data-centre work represents. The release does not assign the round a letter. Calcalist reported a headcount above 400 and named additional Israeli customers; that reporting is not something this newsroom has confirmed.
The checkable facts here are the amount, the date, the lead investor, the participants named in the release’s funding sentence, the $297 million total and the customers named in the announcement. Everything beyond that is either company-stated or third-party reporting, and is labelled as such above.
