## Questions

### Who runs investment decisions at SOSV?

Investment decisions are led by founder and managing director Sean O'Sullivan, along with a partnership that includes general partners such as Dr. David Demarest. The firm operates a collaborative committee structure, but O'Sullivan holds final authority as the founder (per SOSV company filings, 2022).

### How does SOSV source proprietary deal flow?

SOSV sources opportunities through its internal incubator program, EI4, which develops deep tech startups from university research and corporate spinouts. The firm also leverages relationships with academic institutions, IP-rich corporations, and its global office network across the U.S., UK, and China (per the firm's website).

### Does SOSV participate in fund commitments or only direct deals?

SOSV primarily makes direct equity investments in companies, but it also sponsors SPACs that acquire portfolio companies, as demonstrated by the sponsorship of SOSV SPAC I in 2021. The firm does not publicly disclose any fund-of-funds or LP-style commitments (per SEC filings, 2021).

### What investment stages does SOSV typically target?

SOSV targets companies from early-stage incubation to growth-stage follow-ons. The firm is stage-agnostic within the deep tech domain, having invested at seed, Series A, and crossover rounds, with a preference for technology that has been de-risked through the EI4 program (per TechCrunch, 2023).

### Which sectors does SOSV explicitly avoid?

SOSV does not invest in pure software-as-a-service (SaaS) or consumer internet companies unless they involve deep tech elements such as AI or hardware. The firm also avoids commodity-oriented investment in sectors like real estate or basic manufacturing (per the firm's public investment thesis).

### How is SOSV related to its sponsor entity SOSV SPAC I?

SOSV SPAC I is a special purpose acquisition company sponsored by SOSV founder Sean O'Sullivan, formed in 2021 to take deep tech companies public. The SPAC is structurally separate from SOSV's own venture funds but draws on the same deal flow and sector expertise (per SEC filing, 2021).
