Summary
Leo Polovets is a General Partner and co-founder focused on seed investing in deep tech and critical sectors through Humba Ventures and Susa Ventures, deploying $250k–$1M checks into companies in manufacturing, energy, and defense. With 14+ years of engineering experience, he was the second engineering hire at LinkedIn (helping build early Jobs and Groups), worked on payment fraud detection at Google, and built large-scale data cleaning and deduplication systems at Factual. He blends hands-on systems and algorithmic expertise with operator-first investing, favoring companies that require rigorous engineering to de-risk physical and data-heavy problems. Based in the Dallas–Fort Worth area and Caltech-trained in Engineering and Applied Science (CS), he maintains a public-facing technical voice through his blog CodingVC and occasional commentary on startup strategy. An unexpected throughline in his career is a consistent focus on messy, real-world data and fraud/quality problems—skills that translate directly into his sourcing and diligence for deep-tech seed deals.
