HawkEye 360, the global leader in signals intelligence data and analytics, announced an additional close of its Series E financing, raising approximately $23 million in new capital. The second close includes participation from new investors Ghisallo, Principia Growth, and Sixty Degree Capital, as well as continued participation from existing investor Strategic Development Fund (SDF).
“The continued participation from both new and existing investors underscores confidence in our strategy and the progress we’re making as we scale the business,” said John Serafini, CEO of HawkEye 360. “We are advancing our capabilities through the integration of ISA and continued investment in our platform, supporting the signals intelligence our partners rely on to inform their missions.”
HawkEye 360 will use capital to strengthen its balance sheet and continue executing its strategic growth priorities, including the integration of Innovative Signal Analysis (ISA).
“This additional close reflects our disciplined approach to capital formation,” said Craig Searle, CFO of HawkEye 360. “It strengthens our balance sheet and provides flexibility as we continue integrating ISA, advancing our platform, and managing growth in a thoughtful and deliberate way.””
