Millions for AI on the Jobsite: Who Really Controls Construction's Digital Revolution Today?
The past week made it clear that venture capital is flowing more boldly than ever into construction technology — from progress monitoring to concrete quality. We look at who secured funding, and why major building materials players are betting on digital quality control.
01 · AI Funding
Buildots and TAR: Fresh Capital for Construction AI
In the week ending September 21, 2026, Israeli-American company Buildots raised another $130 million in funding, bringing its total funding to date to $297 million. The system it develops is built on a simple yet effective idea: 360° photos from the jobsite are automatically compared against the project schedule and BIM model, allowing site managers to spot delays and discrepancies between design and reality much faster [1].
At the same time, TAR is entering the scene — a startup founded only in 2026 that has already closed a $120 million Series A at a valuation reaching $1 billion. The company isn't focused on construction monitoring, however, but on modular, off-grid power systems for data centers — a segment growing at a pace driven by the AI infrastructure boom. As the weekly Bricks & Bytes roundup notes, alongside these two major deals, several smaller funding rounds also emerged — including in AI-powered construction accounting and low-carbon cement production technology [1].
All of this shows that investors see contech not as a single trend, but as several parallel growth directions: digital oversight of schedules, power for digital infrastructure, and materials decarbonization. It's hard to find better proof that the construction sector has stopped lagging behind technologically.
02 · Concrete Quality
Holcim Bets on Cloud Cycle: Concrete Quality Under Control from A to Z
If progress monitoring represents one pole of digitalization, material quality monitoring is the other — and that's exactly where Swiss giant Holcim placed its investment. The company took an equity stake in UK-based tech company Cloud Cycle, whose solution enables real-time tracking of concrete quality at every stage — from the moment the mix is produced at the batching plant through to delivery on the jobsite [2].
Financial details of the deal weren't disclosed, but the direction itself speaks volumes. More and more building materials and chemicals manufacturers are treating digital quality control not as an add-on, but as a way to reduce the risk of defects, complaints, and costly disputes with contractors. In practice, this means fewer surprises on site and more predictable parameters for the concrete being delivered [2].

Two Poles of the Same Revolution
It's worth putting these two stories side by side, because although they concern different stages of the construction process, they tell the same story: data and artificial intelligence are becoming tools for reducing risk — whether at the level of scheduling and progress (Buildots) or at the level of the material itself (Cloud Cycle and Holcim). In both cases, the goal is the same — less uncertainty, fewer errors, fewer costly fixes.
To see firsthand how these and similar technologies are changing everyday work on the jobsite, visit World of BUILD Expo – International Trade Fair for Construction Technology and Materials. This is where the companies driving construction's digitalization, building materials and chemicals manufacturers, and infrastructure experts all come together — the perfect opportunity to see these solutions up close rather than just read about funding rounds.
