E-commerce software and data platform Assembly said on Tuesday its valuation had crossed US$1 billion following a funding round led by U.S. private equity firm Advent International. The company did not specify the amount raised in the funding round, which also included investment from growth equity firm PSG, and said it would use the money for growth and software development. Assembly, which counts cosmetics group L'Oreal and Unilever among its customers, helps e-commerce merchants scale their business.
