LightTable Raises $22M in Series A Funding Led by Innovation Endeavors

The round also saw participation from Blackhorn Ventures, DivcoWest Ventures, 9Yards Capital, Primary Venture Partners, MetaProp, and Banter Capital.

The company plans to use the funds to scale its QA/QC product, expand its team across all functions, and launch new tools for customers in the U.S. and global markets.

LightTable reads and analyzes construction drawings at an expert level, similar to an experienced architect or engineer, but in a fraction of the time of manual review. Its purpose-built AI models address a major construction challenge caused by disconnected tools and teams, which often leads to design errors, expensive change orders, and project delays.

The platform replaces traditional peer review with a unified, AI-powered workflow that is faster, more cost effective and more accurate. Globally, the construction industry spends over $200B managing risks from document quality issues, and LightTable helps reduce these failures by improving coordination and accuracy across the design process.

LightTable’s flagship AI QA/QC product is already used by major developers and general contractors, including Suffolk Construction, Mill Creek Residential, and Swire Properties, on large, complex projects.

Today, the platform catches about 70% of design errors that would otherwise lead to change orders, compared to roughly 30% with human only review. It also completes reviews in 3–5 days instead of the typical 3–6 weeks required for manual processes.

“Pre-construction is where major projects are won or lost — a single missed conflict in a drawing set can cascade into months of delay and millions in change orders. Yet the workflow still depends on labor-intensive review by a small number of highly specialized experts,” said Scott Brady, Founding Partner at Innovation Endeavors. “LightTable pairs deep construction expertise with multimodal AI that genuinely understands drawings, specs, and the relationships between them. We're excited to continue partnering with the team as they build the foundational AI infrastructure for the future of pre-construction.”

“What drew us to LightTable is just how many steps ahead they are in AI-powered review,” said Mark Johnson, Head of Development at DivcoWest. “In the field, we already see how their core software can apply across all areas of pre-construction and unlock tangible value for project teams. We’re proud to be supporting them through this next phase of growth.”

“Construction projects are only getting more complex — yet the industry has been stuck with navigating the same pre-construction process for decades,” said Paul Zeckser, CEO and co-founder of LightTable. “LightTable is on a path to eliminating billions of dollars in construction waste, and with this funding, we’re able to move even faster. We’re grateful to Innovation Endeavors, our other valued investors, and all of our customers for sharing our vision to create an intelligent operating system for construction.”
