Guthrie AI, a Philadelphia startup building AI-assisted bidding tools for commercial contractors — with an early wedge in the glazing trade — has raised a $4 million seed round led by Chicago Ventures, the company said on July 13.
The company is going after one of the least glamorous corners of construction: the glazing estimator’s inbox. Founder and president Ted Baumgardner is a former Marine intelligence officer who spent years as a glazing estimator, and co-founder and head of product Tuneer De built the software layer around the workflow Baumgardner knew from the inside.
The estimator’s bottleneck
Glazing bids are drowning in administrative work — downloading and organizing drawings, pinning down scope, chasing supplier quotes and reformatting numbers so they land where they need to. That grind is what keeps a skilled estimator from working more jobs.
Rather than sell software alone, Guthrie pairs both. The company describes each account as a hybrid: a “Virtual Bid Assistant” — its proprietary AI workflow automation that downloads and organizes project files, identifies scope, prepares quote requests and routes pricing to vendors — working alongside a dedicated human bid coordinator who watches deadlines and compliance. The system plugs into the tools estimators already live in, including Bluebeam.
“What we built is the app that makes it easy to hire that person, train them, and work with them every day,” said Baumgardner.
The company says 52 glaziers and vendors have already taken on a Virtual Bid Assistant, and that customers are bidding up to 70% more work without adding full-time staff, with bid turnaround falling from weeks to days. Those are Guthrie’s own numbers, but they point at a real bottleneck the trade knows well.
Chicago Ventures general partner Rob Chesney framed the bet on the founder: “Ted knows this trade from the inside and has a tenacious, competitive spirit.” The new capital will go toward expanding Guthrie’s engineering team and deepening its integrations with the software estimators already use.
Guthrie is wagering that the sharpest AI opportunities in construction start narrow — one trade, one workflow, done deeply — before widening out; the company now says it manages bids across more than 40 states. It joins a wave of startups aiming AI at the bid: xBuild is automating roofing proposals, and Bidflow is chasing electrical estimating. The unglamorous back office of the trades is quietly becoming one of contech’s most crowded fronts.
