TL;DRGritt raised $32M for AI robots that attach to existing construction equipment and place solar panels up to four times faster than manual crews.
San Francisco-based Gritt has exited stealth with just over $32 million in combined pre-seed and Series A funding to deploy AI-powered robotic systems on large-scale construction sites, starting with solar farms. The $26 million Series A was led by Obvious Ventures, with Union Square Ventures and Active Impact Investments also participating, following an earlier pre-seed round from First Round Capital, Climactic, Congruent Ventures, and VSC Ventures. The company’s systems do not replace existing construction equipment but attach to it, using robotic arms mounted on standard skid steers and forklifts to pick, transport, and position solar panels with millimeter precision.
The throughput gains are substantial, according to both the company and TechCrunch’s reporting. A typical eight-person crew installs around 800 panels per day, but the same crew working alongside Gritt’s system can place 3,000 to 4,000 panels daily. The company says its machines have placed tens of thousands of panels with zero breakages, a claim that has not been independently verified.
