Archiboost AI Raises $6.2 Million for Construction Document QA/QC Platform

The San Francisco-based construction technology company Archiboost AI has announced a combined pre-seed and seed funding round of US$6.2 million, backed by Hanabi Capital and Marathon Venture Capital. The company, which emerged from stealth in March 2026, develops a platform that reviews construction document sets to detect errors, omissions and coordination issues before documents are issued to the field.

According to the company, the platform reads PDF files and Revit metadata to identify discrepancies between drawings, specifications and code requirements. Vendor-reported figures include more than 550,000 drawing sheets reviewed across projects valued at US$3.5 billion and over 120,000 flagged issues. Claims of detecting up to six times more issues than manual QA/QC and reducing field coordination problems by 70 percent remain vendor claims. Named clients include WRNS Studio, OTJ Architects and RXR.

The company plans to expand its QA/QC engine and introduce a construction administration agent that draws data from Autodesk Construction Cloud and Procore.
