LightTable AI Drawing QA/QC

LightTable is an AI-native pre-construction platform that reads construction drawings to find design errors and omissions before building starts. The company emerged from stealth in August 2025, raised a $6M seed round, and announced a $22M Series A on May 27, 2026 in a Denver-datelined release.

The platform ingests drawing sets from developers and contractors and reviews more than 35 scopes, producing issue findings that teams can comment on and track. The site lists AI issue detection, unlimited collaborating users, review tracking, ball-in-court tracking and cross-discipline coordination. Named customers include Suffolk, Mill Creek Residential and Swire.

• AI issue detection: finds design errors and omissions across more than 35 scopes.
• Cross-discipline coordination: checks consistency between disciplines in the drawing set.
• Collaboration: unlimited users with real-time comments on findings.
• Review tracking: issue history and ball-in-court tracking.
• Prioritization: ranks findings so teams address the most relevant items first.

A residential developer in Vietnam reviews a tower's architecture, structure and MEP drawings before tendering. A general contractor checks revised drawing sets for conflicts before issuing RFIs to designers. A design consultancy runs a QA pass before submitting documents for permit.

Shortens drawing review to 3-5 days versus 3-6 weeks for human-only review, according to the company's release. Catches 70% of design errors that would otherwise lead to change orders, versus 30% for human-only review (vendor claim). Gives owners and contractors an issue history with ball-in-court tracking for accountability.

Design document quality failures drive change orders and rework, and the company cites more than $200B spent globally on this risk. AI review of drawings is becoming a standard pre-construction step as contractors face labor shortages in estimating and coordination. Vietnamese developers and EPC contractors handling large residential and industrial projects face similar coordination risks.

Based in Denver per the press release dateline. Seed of $6M after stealth exit in August 2025; Series A of $22M led by Innovation Endeavors with Blackhorn Ventures, DivcoWest Ventures and 9Yards Capital, plus Primary Venture Partners, MetaProp and Banter Capital.
