Silversmith Capital Partners, a private equity firm, led a $15m Series A round in Northbeam, a machine learning-powered marketing measurement platform. “Marketing spend accounts for a large percentage of brands’ budgets, and yet, many companies have limited insight into which marketing spend is actually driving profitable growth. Northbeam helps brands invest in the growth efforts that make economic sense, which is especially important today given the current macroeconomic picture,” Austin Harrison, Northbeam CEO.
