LightTable, a proptech startup based in Denver, has officially emerged from stealth with a $6 million seed funding round led by Primary Venture Partners, joined by Innovation Endeavors, MetaProp, and angel investors. The company, founded in October 2024 by CEO Paul Zeckser (with co-founders Dan Becker and Ben Waters), builds an AI-driven peer-review platform for real estate development documents. LightTable’s software can process thousands of pages of PDFs—including architectural plans and engineering specs—and deliver coordinated reviews covering constructability, MEP, accessibility, and fire and life safety in just 10 to 45 minutes. The platform then generates a prioritized list of potential issues that might lead to costly change orders or delays, dramatically reducing a traditionally lengthy 3–6-week manual process. LightTable claims its AI uncovers four times more issues than conventional peer reviews and can decrease on-site coordination mistakes by up to 70%. The startup’s first pilot partner is Mill Creek Residential Trust, whose VP of construction praised LightTable’s ability to detect errors in seconds that hillside experts spent weeks seeking. LightTable plans to use the new capital to expand its product engineering team and enrich its domain expertise by recruiting seasoned architects, engineers, and general contractors—recognizing that marrying field experience with AI is key to building robust and nuanced review capabilities.
