Gritt, a startup that combines robotic arms with artificial intelligence to perform physical construction work outdoors, has come out of stealth with $32.4 million in funding. Co-founded by CEO Puneet Puri and CTO Vishal Dugar, the company builds systems that attach to equipment already common on construction sites, such as skid steers and forklifts. Those systems then carry out repetitive, labor-intensive tasks like picking, placing, and assembling materials with millimeter-level precision.
The company is entering an industry under serious pressure. According to the Associated Builders and Contractors, the U.S. construction industry needs an estimated 349,000 net new workers in 2026 to keep pace with demand. That figure is projected to rise to 456,000 in 2027. More than 41% of the current U.S. construction workforce is expected to retire by 2031. At the same time, the industry has experienced a 46% decline in productivity, even as nearly every other major industry has seen significant gains through automation.
The $32.4 million total includes both a pre-seed round and a $26 million Series A. Obvious Ventures led the Series A, with participation from Union Square Ventures and Active Impact Investments. Previous investors First Round Capital, Climactic, Congruent Ventures, and VSC Ventures also joined.
Construction robotics is a growing market. According to Grand View Research, the global market was valued at an estimated $1.6 billion in 2025 and is projected to grow at a compound annual rate of 18%, reaching $3.66 billion by 2030. Investor interest in construction technology has also been shifting toward companies that build machines for physical site work, rather than software tools for project management or back-office tasks.
Still, outdoor construction remains extremely difficult to automate. Factory floors and warehouses are controlled environments. Construction sites are not. The terrain shifts, the weather is unpredictable, and no two days look the same. Most robotics companies so far have concentrated on structured indoor settings or narrow tasks like bricklaying and 3D printing. Gritt's focus is on the messier, less predictable work that happens outside.
"Every wave of automation started with someone willing to go where the work was hardest and least predictable. Gritt is bringing physical AI to the toughest construction sites in the world. Every site they deploy builds the flywheel that makes the system smarter and more capable. That's a compounding advantage that's challenging to replicate from the outside. We look forward to helping Gritt build this new and ambitious category in physical AI."

The company's immediate focus is solar. Gritt's machines have autonomously placed tens of thousands of solar panels on large-scale construction sites, with zero reported breakages. Next on the list are data centers and large infrastructure projects, including bridges and roads.
Gritt is also building what it describes as an intelligence layer for construction supervisors. Its machines already capture terabytes of spatial and operational data every day. The longer-term goal is for that data to do more than record what happened. The company wants its AI to help site managers understand resource flows, spot problems early, and make faster decisions to keep projects on schedule.
"Nobody is solving the repetitive, high-volume manual work that shapes the world's infrastructure. We need an intelligence layer that can complete dexterous tasks and make decisions in an environment that changes every hour. This is one of the most challenging frontiers in physical AI."
— Vishal Dugar, CTO and co-founder at Gritt
Puneet Puri and Vishal Dugar co-founded Gritt, drawing on a team with backgrounds in robotics and AI from Carnegie Mellon, Stanford, and MIT. The company's approach is practical. Instead of designing entirely new machines, Gritt's robotic arms attach to the common construction equipment that crews already own and know how to maintain. Contractors do not need to replace their existing fleets.
The systems work alongside human crews within strict safety boundaries. They handle dangerous, repetitive movements while workers take on other tasks. According to the company, the AI learns from each deployment. A task that originally took months to train now takes days. Gritt says its machines are used by top-10 U.S. construction firms, have been deployed on seven or more active jobsites, and deliver a fourfold efficiency gain with no additional labor.
"Every industry has embraced automation, but outdoor construction sites are exposed, with unforgiving terrain and variable weather. You can't tell a construction site to be less muddy or to stop snowing. Gritt's physical AI is designed to work in this unstructured, outdoor world. Infrastructure is what moves civilization forward, and now Gritt can help build it faster — including solar arrays, data centers, bridges, and roads."

Obvious Ventures led the $26 million Series A. The San Francisco-based firm focuses on companies working in sustainability and health, investing under what it calls a "world positive" thesis. Union Square Ventures and Active Impact Investments participated in the round alongside earlier backers First Round Capital, Climactic, Congruent Ventures, and VSC Ventures.
The $32.4 million total gives Gritt a meaningful financial base for an early-stage construction robotics company. For comparison, task-execution and installation robots in the construction sector raised an average of roughly $27 million per deal in 2025, according to a Zacua Ventures report on construction robotics. That puts Gritt's raise toward the upper end of its peer group.
