LightTable Raises $6 Million to Modernize Pre-Construction Design Review with AI

Company Snapshot
LightTable is reimagining how pre-construction teams review design documents with the power of AI. Based in Denver, this fast-moving construction tech startup has developed an intelligent platform that can analyze architectural and engineering drawings in minutes, uncovering errors, omissions, and coordination risks long before a project breaks ground. By transforming a traditionally manual, weeks-long process into an automated, data-rich workflow, LightTable aims to redefine collaboration between developers, architects, and builders.

LightTable Raises $6 Million to Modernize Pre-Construction Design Review with AI

Primary Venture Partners leads the $6M Seed round to accelerate LightTable’s AI-powered document review platform for design and construction teams.

Intro
On August 19, 2025, Denver-based LightTable announced a $6 million Seed round led by Primary Venture Partners, with participation from Innovation Endeavors, MetaProp, and Banter Capital. The new capital will fuel the expansion of LightTable’s AI-driven platform that accelerates the design document review process, a critical but often slow step in pre-construction.

Founded in October 2024 by Paul Zeckser (CEO), Dan Becker (CTO), and Ben Waters, LightTable is tackling one of the industry’s most persistent inefficiencies: manual peer review of complex design documents. The company claims its software can cut review time from 3–6 weeks to just 10–45 minutes, identify up to four times more issues, and reduce job site coordination errors by up to 70%.

What LightTable Does
LightTable’s platform uses AI to analyze and cross-check architectural and engineering documents before construction begins. The goal is to catch design conflicts early, reduce rework, and eliminate coordination errors that often drive project delays and cost overruns.

Core Capabilities:

• AI-Driven Peer Review: Analyzes design documents in minutes instead of weeks.

• Error Detection: Identifies four times more issues than traditional review methods.

• Job Site Impact: Cuts coordination mistakes by up to 70%.

• Pilot in Progress: Currently deployed with Mill Creek Residential Trust, a leading multifamily developer.
