Q Fund

Investment decisions are made by Managing Partners Liav Ben Rubi and Dana Taigman Koren, supported by Principal Liron Ben Zaken (per the firm website). No investment committee composition or external advisory board is disclosed, suggesting a flat, partnership-driven decision process typical of early-stage vehicles with less than five investing partners.

Q Fund targets early-stage and Seed investments, per its own description. The firm's deep tech emphasis — quantum hardware, robotics, geothermal and nuclear energy — implies a willingness to engage at pre-revenue, prototype-stage companies where capital intensity is high and technical risk has not yet been de-risked by commercial contracts.

Q Fund's stated focus is exclusively on deep tech technologies with a hardware or physical-infrastructure component. The firm does not list enterprise software, consumer internet, fintech, or digital health as areas of interest, making it a sector-negative investor for everything outside its five named verticals: quantum computing, autonomous systems, cybersecurity, advanced sensing, and clean energy infrastructure.

There is no evidence Q Fund has raised or committed to external funds as a limited partner. The firm presents itself as a direct investor in early-stage companies. Without disclosure of its own fund structure or LP base, it is not possible to confirm whether Q Fund itself deploys from a closed-end fund or a rolling capital vehicle.

Q Fund does not publicly describe its sourcing methodology. Given its thematic concentration in hardware-centric deep tech — quantum, autonomous systems, advanced sensors — its deal flow likely originates from Israeli university research labs, defense-technology spinouts, and the technical founder networks that overlap with those domains. The absence of a marketing footprint suggests sourcing is relationship-based and conference-driven rather than inbound.
