Advertising data-management company InfoSum laid off approximately 20 employees earlier this month, representing about 12% of its workforce. The layoffs, which affected engineering and sales teams, were attributed to macroeconomic uncertainty and the company's struggle to meet revenue targets. Specifically, InfoSum has faced challenges gaining traction in the US market with its UK-built privacy-focused platform, failing to secure major anchor clients there despite success with European broadcasters and retailers. The layoffs follow other cost-cutting measures and coincide with the departure of founder Nicholas Halstead.
