One year after raising $16 million, construction technology company Buildots is back to claim another $30 million, this time in Series B funding.

Lightspeed Venture Partners led the round, with participation from previous investors TLV Partners, Future Energy Ventures, Tidhar Construction Group and Maor Investments. This gives the company $46 million in total funding, Roy Danon, co-founder and CEO of Buildots, told TechCrunch.

The three-year-old company, with headquarters in Tel Aviv and London, is leveraging artificial intelligence computer vision technology to address construction inefficiencies. Danon said though construction accounts for 13% of the world’s GDP and employs hundreds of millions of people, construction productivity continues to lag, only growing 1% in the past two decades.

Danon spent six months on construction sites talking to workers to understand what was happening and learned that control was one of the areas where efficiency was breaking down. While construction processes would seem similar to manufacturing processes, building to the design or specs didn’t happen often due to different rules and reliance on numerous entities to get their jobs done first, he said.

Buildots’ technology is addressing this gap using AI algorithms to automatically validate images captured by hardhat-mounted 360-degree cameras, detecting immediately any gaps between the original design, scheduling and what is actually happening on the construction site. Project managers can then make better decisions to speed up construction.

“It even finds events where contractors are installing out of place and streamline payments so that information is transparent and clear,” Danon said. “Buildots also creates a collaborative environment and trust by having a single source telling everyone what is going on. There is no more blaming or cutting corners because the system validates that and also makes construction a healthier industry to work in.”
