Why it's hard
- Leads rounds and underwrites high ownership, high-conviction positions
- Team quality and founder-market fit matter more than standard early traction
- Has specific sector theses rather than being fully generalist
- Looks for category-defining or moat-forming potential even at pre-seed
Primary is accessible to true early-stage companies and will invest before product-market fit, but it is still highly selective because it prefers to lead rounds, concentrates on exceptional founders, and has strong thesis filters around AI, infrastructure, and durable moats.
Green flags
What drives a yes for this firm.
- Exceptional founders building from conviction rather than consensus
- Strong founder-market fit and evidence of steep learning velocity
- A credible path to durable moats through proprietary data, network effects, or domain depth
- Clear customer pain and product vision, even before meaningful revenue
- AI-native execution and the ability to generate concrete outcomes quickly
Red flags
What kills deals and gets a fast no.
- Trend-chasing pitches built around consensus AI narratives with no differentiated insight
- Weak founder-market fit or shallow understanding of the customer problem
- No believable moat path beyond shipping features quickly
- Lack of customer urgency, proof of demand, or evidence of execution velocity
- Products that are technically interesting but disconnected from a concrete market need
How to win
Patterns that lead to successful pitches.
- Lead with founder insight, conviction, and why this team is uniquely suited to win
- Show a sharp, AI-native product thesis tied to painful customer workflows
- Articulate a credible path to compounding moats such as data, network effects, or technical barriers
- Demonstrate speed: customer conversations, pilots, product iterations, and learning loops
- Position the company within one of Primary's active themes like vertical AI, compute, cybersecurity, or industrial transformation

Investment thesis
Core beliefs and strategy behind their investing approach.
Primary Venture Partners is a seed‑specialist that leads pre‑seed and seed rounds across a broad set of technology sectors. Its eight focus areas are Financial Services, Healthcare, Vertical AI, Infrastructure/Compute, Cybersecurity, Consumer, GTM Tech and the "Industrial Evolution," reflecting a conviction that AI is reshaping workflows, infrastructure and end‑user experiences. The firm emphasizes capital‑intensive deep‑tech opportunities such as semiconductors and ocean‑mapping infrastructure when they fit the compute or industrial theses. Geographically, Primary has moved from an NYC‑centric model to an "Investing Everywhere" approach, backing founders from San Francisco to Tel Aviv and across the United States. Core to its belief system is a founder‑centric philosophy: it backs founders who are building from conviction rather than consensus, prioritizes team quality, customer obsession and AI‑native execution, and looks for paths to compounding moats through proprietary data, network effects and deep industry knowledge. While the firm does not publish explicit sector exclusions, its willingness to fund traditionally avoided seed categories (e.g., semiconductors) signals a bias toward thesis‑aligned opportunities over strict sector filters.
Decision patterns
How they evaluate and make investment decisions.
Primary’s investment decisions hinge on team quality and founder conviction over market timing. The firm looks for builders who are customer‑obsessed, product‑driven and AI‑native, emphasizing "slope over intercept"—learning velocity and execution capability over early metrics. It seeks paths to compounding moats through proprietary data, network effects and deep industry knowledge. In practice, Primary leads pre‑seed/seed rounds, activates its Impact team to deliver talent, GTM and fundraising support, and prepares companies for later financing. Representative "Why we invested" posts show repeated leadership in seed rounds across GTM tech, healthcare AI, DevOps AI and quantum software, often before any significant revenue. Deal‑breakers are not enumerated, but the firm implicitly rejects consensus‑driven pitches without clear customer value or moat potential, favoring founders with clear problem‑solving focus and the ability to generate outcomes quickly.
Risk appetite
Primary exhibits a high‑conviction, lead‑oriented risk appetite at the earliest stages. It explicitly leads pre‑seed and seed rounds with $1‑10M checks (average $5‑10M for Fund V) and is comfortable investing in pre‑product, pre‑revenue companies when founder‑market fit and defensible moats are evident. The firm’s willingness to back capital‑intensive deep‑tech (e.g., compute/semiconductor theses) indicates an aggressive stance toward technical risk, mitigated by a large operating platform that provides hands‑on support. While ownership targets are not disclosed, Primary consistently prefers to be the lead investor rather than a follower.
