Artificial intelligence continues to attract the attention of practitioners across the entire construction industry chain, and investors are no exception. Recently, companies offering robot fleets, retrofit robotic products, and AI solutions have received a new round of capital injection in their latest funding rounds.

The following are details of six recent investments in the construction technology sector.

TerraFirma: $115 million

TerraFirma, a construction robotics company founded by former SpaceX engineers, announced on July 14 that it had completed a $115 million funding round, including a $100 million Series A led by venture capital firm Kleiner Perkins.

According to the announcement, the company's full-stack robotic infrastructure platform combines AI-driven pre-construction software with a remote command and control center. The platform also includes semi-autonomous heavy machinery, covering excavators, bulldozers, loaders, rollers, and skid steer loaders. The system allows operators to control the machine fleet through screens.

Texas-based TerraFirma will use the funds to expand its engineering, manufacturing, operations, and construction teams, and continue developing its semi-autonomous heavy equipment systems.

Arrakis: $37.5 million

Arrakis, which helps industrial companies such as construction firms embed AI agents into their technology stacks, announced on July 22 that it had come out of stealth mode with $37.5 million in funding. The funding consists of two parts: a $30 million Series A led by Blossom Capital and a $7.5 million seed round led by Accel.

The company, headquartered in London and Paris, combines frontier-deployed AI engineers with a model-agnostic enterprise AI platform and applied AI research for industrial operations such as construction. According to Arrakis, this enables potential companies to train AI agents within weeks and deploy them into existing systems.

Arrakis will use the funds to triple its headcount, strengthen security and platform capabilities, and drive its expansion into the United States, Europe, and the Middle East.

Gritt: $32.4 million

Gritt, which retrofits existing equipment such as skid steer loaders and forklifts with robotic arms and AI systems, announced on July 21 that it had secured $32.4 million through Pre-Seed and Series A funding rounds. The $26 million Series A was led by Obvious Ventures.

The product of this Belmont, California-based company enables machinery to pick, place, assemble, and transport materials with millimeter-level precision in dynamic environments, Gritt claims. After deploying its machines on large construction sites, Gritt can capture and process data in real time, providing support for site supervisors.

Additionally, Gritt's system is adaptive, learning from each deployment and reducing task time from months to days.

Monumental: $32 million

Monumental, a hardware and software development company aiming to solve labor shortages through robotics, announced on July 15 that it had completed a $32 million Series B funding round, led by Khosla Ventures.

The company's AI software platform, Atrium, controls its robot fleet, which acts as construction crews. According to the company, these machines use advanced sensors, computer vision, and small cranes to precisely lay bricks and mortar. To date, these robots have built walls for schools, community centers, hotels, and a section of canal wall, as well as walls for more than 100 homes in the Netherlands and the UK.

The key business model of this Amsterdam-based company is that clients hire it as an independent subcontractor and pay per completed wall. This relieves clients of the risks of owning and operating the robots.

With this funding, Monumental will expand its hardware and software engineering teams, increase the number of robots on European construction sites, and broaden the range of construction tasks the robots can complete. Additionally, the company plans to launch operations in the United States this year.

Buildforce: $10 million

Buildforce, a technology-driven staffing company focused on electricians, announced on July 28 that it had completed a $10 million Series A funding round, led by investment management firm Saepio Capital.

The company uses its proprietary platform to connect electricians with electrical contractors. It provides a mobile app for electricians to find work and a web-based application for builders to hire electricians. As of July 28, Buildforce electricians have accumulated over 2 million hours of work across more than 2,000 commercial construction projects.

Buildforce, headquartered in Houston and Austin, Texas, will use the funds to continue its national expansion and further develop its technology.

SubBase: $7 million

SubBase, a construction technology company focused on building material procurement, announced on June 17 that it had completed a $7 million Series A funding round, led by venture capital firm FINTOP.

Fort Lauderdale, Florida-based SubBase provides an online platform that unifies the procurement process. Specialty builders and self-performing general contractors can use the platform to request quotes, place orders, communicate with suppliers, track deliveries, and reconcile invoices. SubBase also offers integrations with construction accounting systems.

With this funding, the company will drive product and engineering growth, expand its supplier network, and support an AI-driven intelligence and workflow layer trained on pricing, supplier performance, and delivery data.
