  • SkySafe

    Participated · Series B · Dec 2021

    SkySafe develops modular hardware and software airspace security and management systems that apply advanced radio technology, reverse engineering, and deep threat analysis to differentiate authorized drones from threats. Its offerings can be fixed, mobile or temporarily installed and tailored to specific regulatory environments to protect public spaces. The company positions its technology as infrastructure to enable commercial drone adoption for surveying, disaster relief, delivery, and other applications. SkySafe’s systems are deployed to customers in more than 30 countries, including international airports, prisons, stadiums, border patrol, law enforcement agencies and allied militaries. The company reached profitability in 2020 and says the new capital will accelerate strategic hiring, R&D, and expanded production. SkySafe is headquartered in San Diego and was founded in 2015. SkySafe develops radio-wave counter-drone systems that detect and stop unauthorized drones by projecting RF signals from a perimeter of nodes or a mobile vehicle (even a Jeep) to force unapproved drones to land or leave while permitting authorized flights. The company also builds a mobile defense vehicle intended to accompany armed forces and protect moving perimeters from drone attacks or surveillance. SkySafe says its RF approach can detect and deter drones at the same maximum range a drone can travel from a pilot and may be simpler to deploy than laser- or net-based alternatives. Now two years after launch, SkySafe raised an $11.5M Series A led by Andreessen Horowitz, following a $3M seed also led by Andreessen last year. SkySafe secured a $1.5M Department of Defense contract with Naval Special Warfare to provide counter-drone tech to the Navy SEALs. CEO Grant Jordan, an MIT graduate, worked on anti-drone technology for four years at the Air Force Research Lab and says the company plans demonstrations, tests, and exercises for DoD customers over the next year and aims to have systems in the field in 2018. SkySafe builds systems that detect and disable drones flying where they shouldn’t by monitoring airwaves, identifying drone signal signatures, whitelisting authorized craft, and taking control of malicious aircraft. Its technology focuses on surgical mitigation rather than broad jamming, allowing operators to safely assume control of a target drone. The company says it deploys perimeter nodes that monitor facilities and alert customers to unauthorized drones. Target customers include airports, prisons, stadiums, border protection, and other critical infrastructure and event venues. SkySafe is an early, six‑month‑old, six‑person company led by cofounder and CEO Grant Jordan, who has a background at MIT and the Air Force Research Lab. It is working with pilot customers and test installations and plans a broader launch in the fourth quarter of the year.

  • Activ Surgical

    Participated · Series B · Sep 2021

    Activ Surgical develops artificial intelligence and augmented reality technologies to improve surgical procedures, primarily through its ActivSight endoscopy imaging system. ActivSight, cleared by the FDA in April 2021, attaches to standard laparoscopes and arthroscopes and uses machine‑learning algorithms to add real‑time measurements of blood flow, tissue perfusion, and vascularity to the camera feed. The system is housed on the ActivEdge platform, which also hosts ActivInsights — augmented‑reality overlays powered by robotics and advanced AI trained on the company’s annotated imaging data. The company plans a worldwide launch and rollout of ActivSight and says the new funding will be used to scale the business and add resources for that debut. Financially, Activ added a $15M extension to its Series B, bringing that round to $60M and substantially increasing its lifetime fundraising since 2020. Hikma Ventures will support deployment efforts, including introductions in the Middle East. Activ Surgical builds intraoperative imaging hardware and software to give surgeons enhanced visualization during minimally invasive procedures. Its primary product, ActivSight, is a hardware module that fits between an endoscope and a white-light camera to visualize blood flow and other structures in real time without injectable dyes. ActivSight received FDA 510(k) clearance in April 2021 and has been tested in a 70-patient clinical trial at the University of Texas Health Science Center and the University of Buffalo. The company plans near-term commercialization of ActivSight in hospital systems across seven states and seeks CE certification to enter seven European countries in 2022. Longer term, Activ Surgical is developing an AI software suite called ActivInsight to analyze intraoperative data, autonomously annotate key structures (nerves, arteries, veins) and return machine-learned guidance to surgeons. The company has raised $45 million in this Series B and $77 million in total to date to support commercial rollout and its AI roadmap. Activ Surgical develops computer vision and AI-powered surgical vision software and connected imaging hardware for use in laparoscopic and arthroscopic procedures.
