Main Capital’s merger of Cisbox and Millum is a classic buy-and-build move designed to create a scaled pan-European source-to-pay software platform with stronger geographic coverage across the DACH and Nordic regions. Strategically, the deal combines two complementary SaaS businesses with recurring-revenue models—Cisbox, bringing AI-powered procurement and invoice automation to Germany, and Millum, adding Nordic procurement depth and hospitality-sector specialization, thereby broadening the product suite for SME and mid-market customers. The transaction suggests Main is not just combining revenue bases, but building a more defensible “Office of the CFO” software group with greater cross-sell potential, regional reach, and platform value for a future exit.
