Khoi Nguyen, P.E., GC
Licensed P.E., GC, and plan-check professional who has designed and reviewed thousands of plans, and bid and built hundreds of real projects, so Plankore is built around how jobs actually get estimated.
Plankore comes from people who have drawn plans, checked plans, bid jobs, built jobs, and shipped software that operators actually use.
"Bidding was my pain. I tried the existing tools and none of them worked the way I needed. So we built the one I actually wanted, and it shows me where every number comes from."
Other tools hand you a number. Plankore shows you the math.

Licensed P.E., GC, and plan-check professional who has designed and reviewed thousands of plans, and bid and built hundreds of real projects, so Plankore is built around how jobs actually get estimated.

CMU Ph.D. and former tech lead at Meta Reality Labs, with 48 papers and 4,800+ citations in computer vision. Now building the engine that reads, measures, and reasons over your plans.

Head of Product for Yelp’s $1B SMB business and a Chicago Booth MBA, with 15 years turning messy operator workflows into software used by 7M businesses, including contractors.
“As a contractor, I don’t just need a faster estimate. I need to know where every number came from before I put my name on a bid.”
That is why Plankore starts with accurate, line-by-line takeoff and estimating today — and builds toward traceable AI bidding next.
