Sapir Venture Partners

Sapir Venture Partners is a mentorship-driven micro-VC firm based in Jerusalem, Israel, founded in 2015 by experienced angel investors and former operators. The firm is led by Founder and Managing Partner Aaron Zucker, who previously ran A2Z Venture Partners, an angel fund, and has served on the founding teams of multiple technology ventures. Sapir focuses on pre-seed stage investing and venture creation in biotechnology and deep-technology sectors, partnering with scientific and technical founders who are commercialising cutting-edge science to solve meaningful global challenges. The firm's geographic focus spans Israel, Boston, and New York, with most deals flowing to Israeli founders pursuing US commercialisation. Sapir writes initial checks from $100,000 to $5 million, with a typical sweet spot around $1.5 million, and has made approximately 41 disclosed investments across its history. The portfolio concentrates on biotech, AI and deep tech, health technology, and hardware and robotics. Named exits include Glassbox, Suridata.ai, Strattic, and one additional acquisition — four exits across a portfolio of 24 active companies. Recent investments include Fabric (B2B media and information services, January 2025), Serinus Biosciences, and Lidwave. Beyond capital, Sapir is structured around intensive mentorship — providing hands-on operator support and go-to-market help for scientific founders who are strong in the lab but earlier in their commercialisation journey. This model positions the firm as a genuine venture partner rather than a passive financial investor, with Zucker and the broader Sapir network contributing strategic guidance at the earliest and most formative stage of company-building.
