HawkEye 360, a US-based provider of radio frequency (RF) satellite data, completed a $145m series D round yesterday featuring professional services firm Jacobs.

The round was co-led by growth equity firm Insight Partners and Seraphim Space Investment Trust and included Strategic Development Fund (SDF), a vehicle for United Arab Emirates’ Tawazun Holding entity.

Family office Advance, Gula Tech Adventures, 116 Street Ventures, New North Ventures, Razor’s Edge Ventures, NightDragon, Shield Capital and Adage Capital also took part in the round, along with SVB Financial Group’s SVB Capital unit.

Founded in 2015, HawkEye 360 provides space-based data and analytics services through a network of commercial satellites ​able to identify, process and geolocate a broad set of RF signals for purposes such as national security operations and environmental protection.

The company intends to use the funding to expand its satellite constellation and complementary infrastructure, and accelerate the growth of its services across the humanitarian, environmental, commercial and national security sectors.

This round took the total capital raised by the company to $302m, it said. It secured $55m in an April 2021 series C round led by venture capital firm NightDragon and backed by mapping software developer Esri, Advance, Razor’s Edge Ventures, Shield Capital, Dorilton Ventures and Adage Capital.

The company had already closed an $85m series B round in late 2019 that included Esri, aerospace manufacturer Airbus, commercialisation firm Allied Minds (which subsequently exited to Advance), Razor’s Edge Ventures, Shield Capital, Advance and undisclosed other investors.

Early HawkEye 360 backers include defence technology producer Raytheon and diversified Japan-headquartered conglomerate Sumitomo’s US subsidiary, Sumitomo Corporation of Americas, as well as Space Angels, Razor’s Edge Ventures and Shield Capital.
