Denver-based construction technology company LightTable has raised $22 million in a Series A funding round led by Innovation Endeavors. Existing investors, including Blackhorn Ventures, DivcoWest Ventures, Primary Venture Partners, and MetaProp, also participated.

The company develops AI software that reviews construction drawings and project documents before construction begins. Its platform is designed to identify design conflicts, missing information, and coordination issues during the pre-construction phase.

LightTable said the new funding will support product development, team expansion, and broader market growth in the U.S. and international markets.

“Construction projects are becoming more complex, while many pre-construction workflows still rely on manual processes,” said Paul Zeckser, CEO and co-founder of LightTable. He added that the company plans to accelerate product development with the new capital.

Construction firms continue to face high costs from project errors

Construction companies spend significant amounts on rework, delays, and document-related issues each year. Industry studies have linked design coordination problems and communication gaps to rising project costs and schedule overruns.

Many of these issues begin during pre-construction, when architects, engineers, and contractors review thousands of pages of drawings and specifications manually.

Traditional peer review processes can take several weeks, especially on large projects. LightTable said its AI-based review system can reduce that timeline to a few days by analyzing drawings and specifications automatically.

The company’s platform uses computer vision and language models to review relationships between drawings, technical specifications, and project details across multiple construction scopes.

Investors see growing demand for AI in construction workflows

Innovation Endeavors said the investment reflects increasing interest in AI applications for industrial and construction workflows.

“Pre-construction plays a major role in project timelines and budgets,” said Scott Brady, Founding Partner at Innovation Endeavors. “LightTable combines construction expertise with AI models built to analyze complex project documents.”

DivcoWest Ventures, the venture arm of real estate investment firm DivcoWest, also joined the round. According to the company, LightTable’s software could help improve efficiency across different stages of pre-construction planning.

The company said its platform has already been used on projects representing more than $3.5 billion in construction value. Customers include contractors and developers such as Suffolk, Mill Creek Residential, and Swire.

LightTable focuses on assisting project teams rather than replacing them

LightTable said its software is intended to support architects, engineers, and project teams instead of replacing them.

The platform flags potential issues during document review so teams can focus on design decisions, coordination, and problem-solving. The company currently supports more than 35 construction review categories, including structural, electrical, and plumbing systems.

With the latest funding round, LightTable plans to introduce additional tools aimed at improving pre-construction workflows and project coordination.
