“Can a vertical SaaS own the entire procure-to-pay data spine of a construction company by digitizing every paper touchpoint from site to accounting?”
CATHAGO is a German ConTech SaaS founded in 2021 that digitizes the procurement-to-invoice-check workflow for construction companies. The product spans order management, digital delivery notes, and automated invoice verification with 3/4-way matching, integrating into ERP (Nevaris, RIB, BRZ), DMS, and accounting (Datev) systems. Not an embedded finance company — no BaaS, payments, lending, or card programs in its stack.
