HawkEye 360 Adds $23M to Series E Funding

HawkEye 360 has raised a further 23 million dollars to its Series E funding round. New investors Ghisallo, Principia Growth and Sixty Degree Capital participated in the round. Existing investor Strategic Development Fund also participated in the round. This comes after HawkEye 360 raised a mix of debt and equity financing valued at 150 million dollars to support the acquisition of Innovative Signals Analysis in December of 2025. The company said it will use this new capital to strengthen its balance sheet and continue the integration of Innovative Signal Analysis. Craig Searle, chief financial officer of HawkEye 360, commented that this additional close reflects the company's disciplined approach to capital formation. It strengthens the balance sheet and provides flexibility as the company continues integrating ISA, advancing its platform and managing growth in a thoughtful and deliberate way, he said. HawkEye 360 provides radio frequency detection and monitoring with data acquired from its satellite constellation. Earlier this year the company commissioned three new satellites into the constellation.
