Primary Venture Partners

What Primary Venture Partners does

Primary Venture Partners is a specialized seed-stage venture capital firm founded in 2015 by Ben Sun and Brad Svrluga, headquartered in New York City. The firm invests at pre-seed and seed across eight sector verticals — Fintech & Enterprise AI, Healthcare, Vertical AI, Infrastructure/Compute, Cybersecurity, Consumer, GTM Tech, and Industrials — writing checks of $1M–$10M in roughly 40–50 companies per fund vintage. As of February 2026, Primary closed its fifth fund at $625M (described as the largest standalone seed fund in the market), bringing total assets under management to $1.6B–$1.65B across five vintages. Existing limited partners doubled down on Fund V and several new mission-driven institutions joined as first-time LPs.

The firm's differentiated offering combines capital with a 60+ person operating bench organized into Go-to-Market, People & Networks, Strategic Finance, Design, Labs, and Operations groups — supported by PrimaryOS, an internal AI engine staffed by a Founding Engineer and AI Operations Analysts. Primary Labs operates as an in-house incubation engine that has spawned companies including Tabs, Ollie, and Eos. The firm has produced nine unicorns and two cash exits above $500M from Fund I, and its portfolio includes Etched (transformer-specialized AI chip, co-led $120M Series A), Haiqu (quantum OS), The Biological Computing Company (biological compute), Inspiren ($100M Series B), Lyric ($43.5M Series B), Tabs ($55M Series B), Maybern ($50M Series B), Teleskope, Tokaido Health, and Dandelion Health.

Primary's revenue model follows standard venture fund economics: management fees on committed capital under management (~$1.6B AUM across five vintages) plus carried interest on profitable exits. The firm invests nationwide from NYC, with portfolio and coverage spanning San Francisco, Chicago, Seattle, Virginia, D.C., and Tel Aviv. Distribution is direct and founder-facing — content-led thought leadership (partner-authored theses, The Compute 100 newsletter/podcast, Request for Startups), sector-specialized partner relationships, and structured inbound pathways ([email protected], [email protected], Mastermind Network).

Core offering

Primary Venture Partners is a specialized seed-stage venture capital firm that raises institutional limited-partner capital into multi-year seed funds and deploys $1M–$10M checks into 40–50 pre-seed and seed-stage companies per fund. Beyond capital, the firm offers an embedded 60+ person operating platform (talent acquisition, go-to-market, design, strategic finance) and operates an in-house incubation engine (Primary Labs) that launches new companies, supported by an internal AI operations layer (PrimaryOS).

Product overview

Primary Venture Partners is a specialized, scaled seed-stage venture capital firm (not a single SaaS product) whose offering is a tightly integrated platform combining an investment product (Primary Fund V — $625M seed fund, $1.6B+ AUM) with an internal AI engine (PrimaryOS) for firm operations, an incubation engine (Primary Labs) that spins out companies like Tabs, an industry research initiative (The Compute 100) tracking the semiconductor and compute value chain, a founder network (Mastermind Network), and a 60+ person operating team (Primary Impact) that delivers GTM, talent, finance, and design services to portfolio companies. Together, these modules let Primary lead pre-seed and seed rounds in 40–50 companies every three years while embedding operational muscle from day one.

Direct peers

• Forerunner: Forerunner is one of the largest dedicated seed/early-stage venture firms in the US, with a comparable consumer-and-broad-vertical platform and Kirsten Green's sector-led approach. Most directly comparable to Primary's model of leading concentrated seed rounds with embedded operating support.
• Lerer Hippeau: NYC-based dedicated seed-stage venture firm with overlapping portfolio (co-invested with Primary in Teleskope). Operates a smaller fund than Primary but uses a similar thesis-led, founder-support-driven seed model and shares many of the same NYC ecosystem relationships.
• Uncork Capital: Uncork Capital is a dedicated seed-stage firm with a multi-hundred-million-dollar fund and a long-running operator-led platform. Closely comparable in stage focus and check size to Primary's pre-seed/seed strategy.
• Collaborative Fund: Collaborative Fund is a thesis-driven, multi-vertical seed and early-stage venture firm with comparable AUM scale (>$1B). Shares Primary's pattern of leading concentrated seed rounds across differentiated sectors and publishing thought leadership to drive inbound deal flow.
• Costanoa Ventures: Costanoa is a dedicated early-stage venture firm with a multi-sector partner-led structure and focus on enterprise and consumer seed. Comparable in stage, check size, and partner-led specialization to Primary's model.
• Eniac Ventures: Eniac is a NYC-based dedicated seed-stage venture firm with overlapping portfolio (co-invested with Primary in Pelgo). Operates a similar pre-seed/seed platform with a focus on enterprise and consumer AI.

Emerging players

• Betaworks: Betaworks runs a 'startup studio' model that originates companies in-house, directly comparable to Primary Labs' incubation engine (Tabs, Ollie, Eos). Operates at smaller scale but uses a similar build-not-buy pipeline.

Broad incumbents

• Bain Capital Ventures: Bain Capital Ventures is the early-stage arm of a large multi-strategy investment firm with a $3B+ platform that includes dedicated seed activity. Overlaps with Primary on enterprise AI, fintech, and infrastructure seed investing as part of a broader portfolio.
• Index Ventures: Index Ventures is a global venture firm that leads seed and early-stage rounds in enterprise AI, fintech, and frontier tech. Comparable to Primary on stage and sector overlap, but at a much larger AUM scale and with a more international footprint.
• Lightspeed Venture Partners: Lightspeed is a multi-stage venture firm with significant early-stage activity and recurring co-investor alongside Primary (led the Series B in both Tabs and participated in Inspiren). Comparable on stage overlap and sector coverage, though its fund sizes are far larger and its mandate broader than a dedicated seed.
