Proof of Usefulness Score
Category Standard

BuildZoom is a mature, high-value platform addressing significant information asymmetry in the construction industry through data-driven contractor vetting. While the submission input was low-effort (e.g., claiming 'most people' have used it and omitting financial metrics), independent verification confirms substantial scale: ~$20M-$50M in annual revenue, tens of millions in funding, and a massive database of over 350 million building permits. The project scores highly on utility, innovation (ETL of messy municipal data), and traction, fitting the 'Much larger scale' calibration tier. The final score is dampened only by the poor quality of the submission evidence.
