Opus Capital Ventures

General Partners Dan Avida, Gill Cogan, Joseph Cutts, and Phil Greer form the core investment committee. Serge Plotkin serves as Venture Partner, sourcing deals and contributing technical diligence, particularly for Israeli-originated companies. Greer provides continuity from the Weiss, Peck & Greer franchise that preceded Opus.

The partnership draws on a deep Israeli network through Dan Avida and Serge Plotkin, alongside Silicon Valley relationships built since the 1970s Weiss, Peck & Greer days. Advisors such as former U.S. Ambassador to Israel Daniel Kurtzer and Francisco Partners founder Sandy Robertson extend the sourcing reach into government and secondary-market channels.

Opus Capital Ventures is structured as a venture capital firm managing committed capital from limited partners—it is not a family office. The firm traces its roots to Weiss, Peck & Greer Venture Partners, founded in 1971, and now invests out of Menlo Park across a portfolio of more than 350 companies historically.

Opus operates as a direct investor, writing early-stage checks from seed to growth into technology companies. There is no public indication that the firm makes fund-of-fund commitments; its listed activities center on company-level equity investments.

The firm's disclosed portfolio concentrates on enterprise application software, enterprise infrastructure, internet platforms, semiconductors, and wireless. Sectors such as consumer brands, biotech, and fintech are absent from its stated current portfolio and historical exit list, though no explicit exclusionary policy is published.

Opus targets early-stage, seed, start-up, and growth rounds, typically leading or co-leading initial institutional rounds in technology companies. Its operating-partner-heavy general partner team aims to guide companies from early architecture to exit, a pattern visible across its SolarEdge, Sisense, and TrapX positions.

The firm co-invests regularly in syndicated early-stage rounds, often alongside operators and venture firms active in Israel and the Valley. The adviser roster—including Richard Rosenberg and Sam Nunn—suggests occasional co-investment with large institutions, though Opus does not publish a formal co-investment policy for LPs.
