Yaroslav Azhnyuk

Yaroslav Azhnyuk founded The Fourth Law in Kyiv in 2023 to develop scalable onboard autonomy for drones, working with engineers, PhDs, operators and veterans. Identified as its founder and CEO in the company's July 2025 announcement, he made mass deployment a central priority: “Massively scalable drone autonomy is the single most important defense technology of this decade.” He had previously co-founded and led Petcube, the connected pet-camera company.[2][3][4]

In his May 2026 Latent Space interview, Azhnyuk recalled deciding in 2023 that the war would continue much longer and that software-defined drones, AI and fragile supply chains were changing defense. He saw software updates as a way to improve battlefield capabilities rapidly and chose to build a technology company to strengthen the defense of Ukraine and the free world. He also co-founded and invested in Odd Systems, which develops thermal cameras and FPV drones; he described starting it with his Petcube co-founders, partners and friends.[1][2]

The Fourth Law's first launched product addressed terminal guidance. An operator flies toward a target and locks onto it visually; an onboard computer then guides the final approach, continuing even if the visual connection is lost. Azhnyuk explained that low-altitude flight can put a drone behind a hill, forest or the Earth's curvature, creating a radio shadow precisely when the operator needs to see the target. The July 2025 announcement described the handoff to onboard AI during the final 500 meters of flight.[1][2]

Azhnyuk distinguished communication resilience from autonomy: fiber optics strengthen the communication link, while AI takes over operator functions. The two can be combined. He also distinguished terminal guidance, where a human selects and approaches the target, from broader autonomy that includes navigation, target detection and engagement decisions.[1]

Azhnyuk said he defined a five-level framework inspired by self-driving autonomy: terminal guidance; bombing; autonomous target detection and engagement decision; autonomous navigation; and autonomous takeoff and landing. The Fourth Law's 2025 roadmap presented a related sequence, specifying GPS-denied navigation. These stages described the company's vision for fuller autonomy rather than establishing that every stage had been delivered.[1][2]

His engineering emphasis extended beyond individual AI capabilities. Azhnyuk described a long tail of edge cases and a substantial gap between a prototype, a system ready for production in millions of units and one actually deployed at that scale. His eight dimensions of battlefield autonomy covered capability level, platform, domain, higher-order coordination such as swarms, environment, command and control, infrastructure and deployment scale. Infrastructure included simulation, data collection, security and deployment mechanisms—systems that must be developed and integrated alongside the autonomous functions.[1]

Azhnyuk framed his decision to make weapons as a moral obligation to resist the invasion, while crediting the armed forces with the actual fighting: “The actual fighters and defenders and heroes are people in the armed forces. We’re just support.” Asked about the future misuse of technology, he acknowledged that makers bear responsibility but argued that Ukraine's immediate survival needs required action before every possible consequence could be resolved.[1]

In the same interview, he predicted that within five to ten years using weapons without AI would become immoral because, in his view, they would be more likely to cause collateral or unwanted damage. He argued that safety work should not slow development essential to survival, while acknowledging risks from wrong decisions and different responsibilities in environments containing civilians. These were his ethical arguments and predictions, rather than demonstrated comparative safety results.[1]

Azhnyuk also emphasized cost to effect. Recalling a discussion about a laser counter-drone system at a defense conference, he questioned whether an expensive system could handle the mass of inexpensive drones that its purchase price represented. His broader argument favored countermeasures that could be manufactured widely, replaced affordably and upgraded quickly. He nevertheless cautioned against treating drones and AI as the whole of warfare, stressing the continuing interaction of infantry, artillery, armor, reconnaissance and logistics.[1]

Before this defense work, Azhnyuk spent a decade leading Petcube. That earlier career provides context for his experience commercializing connected hardware and working with the collaborators who later joined him in defense technology.[3][4][1]

Born and raised in Kyiv, Azhnyuk studied applied mathematics at Kyiv Polytechnics. He co-founded Petcube in 2012 with Alex Neskin and Andrey Klen. Neskin created the original prototype for his dog Rocky: a camera and motor-mounted laser pointer controlled through a web browser. The founders traveled to China to investigate manufacturing, tested demand through Kickstarter and, after unsuccessful attempts to manufacture in Ukraine, worked with a Ukrainian partner experienced in Chinese contract manufacturing. The first product reached the market in 2014, more than two years after its inception. Azhnyuk recalled living in San Francisco from 2014 to 2020 while building the company.[1][4]

Azhnyuk recalled landing in Kyiv late on February 23, 2022, with his then-fiancée, shortly before the invasion began. His family packed their belongings and spent 17 hours driving west. On September 19, 2022, Petcube named Anastasia Kukhar as his successor as CEO. Azhnyuk moved to president while remaining board chairman, with plans to continue working on long-term projects and supporting Kukhar. The announcement also recorded his consideration of defense-related projects, preceding The Fourth Law's founding the following year.[1][3][2]
