Lesiv contributed her expertise from prominent investment firms like 8VC and Founders Fund, alongside a background in journalism and research, informing the firm's analytical approach. Their shared insight was to identify and empower entrepreneurs committed to building technically demanding, impactful companies.
Humba Ventures primarily serves founders building disruptive technologies across critical domains, including automation, defense, climate, and biotechnology. The firm aims to provide more than just capital, offering strategic guidance, industry introductions, and support to facilitate subsequent funding rounds for its portfolio companies. Its long-term vision is to unlock society's potential by nurturing enterprises that address humanity's most pressing challenges through profound technological innovation.
Key people at Humba Ventures.
Humba Ventures is an early-stage venture capital firm focused on investing in deep tech and hard technology sectors, including defense tech, robotics, automation, energy, and advanced hardware innovations. Their portfolio spans a wide array of cutting-edge technologies such as nuclear microreactors, drone swarms, surgical robots, genomic data platforms, and AI-enabled defense solutions. The firm aims to back startups that solve complex, technical problems with hardware and software innovations that have significant real-world impact, particularly in critical national sectors like energy and defense[1][2][3].
Their investment philosophy centers on partnering closely with founders in pre-seed and seed rounds, providing not only capital but also operational support and domain expertise. Humba Ventures emphasizes ethics and integrity, maintaining confidentiality and avoiding conflicts of interest.

Founded around 2022-2023, Humba Ventures was established as a sister fund to Susa Ventures, a well-known seed-stage firm with successful investments in fintech and software companies like Robinhood and Flexport. Leo Polovets, co-founder of Susa Ventures and a former engineer at LinkedIn and Google, serves as a general partner at Humba. His engineering background and experience in enterprise software shape Humba’s deep tech investment approach. The fund was created to focus on hard tech sectors that require specialized knowledge and longer development cycles, such as defense and energy technologies, areas less covered by traditional venture capital[1][6].
The firm’s early investments include companies like Treeswift (forest monitoring robots), Antares (nuclear microreactors), and Swarm Aero (autonomous military drone swarms), reflecting its commitment to hardware-heavy, high-impact startups. Humba’s evolution reflects a strategic pivot from Susa’s software-heavy portfolio to a more technically demanding and capital-intensive space[1][2].
