What Bild AI does

Bild AI automates Division 8 estimating - doors, frames, and hardware - end to end. Bild AI reads blueprints and specs, generates opening (door) schedules automatically, prices the bid, and exports it directly into the ERPs Division 8 shops already run on, including Comsense, Avaware, and ProTech. Division 8 estimating is the brutal trifecta of nitty-gritty details, where typos cost hundreds of thousands, and timelines are tight. Thousands of pages of specs, hardware sets cross-referenced by hand, and a single missed opening that can sink a bid's margin. Bild AI collapses days of takeoff into hours, and clients have bid 50% more with smaller estimating teams. Backed by Khosla Ventures (YC W25).

AI estimating & detailing for Division 8 doors

What is your company going to make? Please describe your product and what it does or will do.

We built a product that automates Division 8 estimating - doors, frames, and hardware - from blueprints to bid pricing. It reads specs, generates door schedules automatically, prices the bid, and exports directly to ERPs like Comsense, Avaware, and ProTech. This replaces days of manual, error-prone work with software that cuts estimating time to hours and improves bid accuracy.

Where do you live now, and where would the company be based after YC?

We live in San Francisco, CA, and the company is based here now and will remain here after YC.

Explain your decision regarding location.

San Francisco is where we are and where most construction tech innovation happens. Being here connects us to customers, investors, and the talent we need.
