Investment thesis
Vertex Ventures US is a Palo Alto-based early-stage VC, the US arm of Temasek-backed Vertex Holdings (~$6B AUM globally). Fund VI $250M (2024 vintage). Invests Seed to Series B across US enterprise SaaS, cybersecurity and deep tech. Cheques $2-10M, lead or co-lead.
Quantum bet: Quantum Art (Israeli trapped-ion quantum computing with multi-qubit gates, early investor alongside Battery Ventures). Architectural approach focused on faster gate times via optical manipulation.
Value-add: Temasek-backed LP base offers global quantum syndicate connectivity (Temasek led Pasqal Series B, invested in Quantonation Fund II); cross-continental Asia-US bridge for Israeli founders.
Not a quantum specialist — single opportunistic bet. Relevant via the Temasek halo for Asia-Pacific expansion.
Anti-thesis
The patterns that trigger a fast no with this fund.
- US fund's stated mandate is enterprise infrastructure and SaaS at Series A / B with clear 2 to 3 year revenue ramps, quantum hardware violates both the stage and revenue-pattern thesis
- Singapore parent (Temasek) has its own deep-tech and sovereign quantum vehicles (Quantum Engineering Programme, SGInnovate), so quantum deal flow likely gets routed away from Vertex US to keep mandates clean
- Partner bench is heavy on ex-enterprise-software operators (VMware, Cisco, Salesforce alumni), with no public quantum or physics background, limiting technical diligence credibility with quantum founders
- No portfolio markers, no thesis publications, and no conference presence (Q2B, IEEE Quantum Week) suggesting quantum is not an active sourcing priority
