DataDriven needs industrial OCR, every tender document in Romania, scans included, and cloud pricing made that a luxury: Azure Document Intelligence billed per page, and GPU instances rent at rates designed for venture budgets. Mihai's replacement is a single RTX 3090 in his office running Tesseract plus his own quality-validation classifiers, processing about 1,500 pages per hour, powered by the solar panels on the roof, so the marginal cost per page is approximately zero. A consumer GPU is not a data center, but a solo founder's workload rarely needs one; it needs sustained, predictable throughput on a task that tolerates batch processing. When an AI API is your biggest variable cost, price out the unfashionable alternative of one good machine you own, because the payback period is often measured in weeks.
