Ben Sun

Who they are

Ben Sun is Co-Founder and General Partner at Primary Venture Partners — he previously founded Community Connect Inc., which published BlackPlanet.com, AsianAvenue.com, and MiGente.com and was among the top 25 most-trafficked internet properties before being acquired by Radio One.

Person

Ben Sun co-founded Primary Venture Partners in 2015 with Brad Svrluga, starting from scratch with just the two of them as a seed-stage NYC-focused fund. Before that he ran LaunchTime LLC, an early-stage investor and incubator whose portfolio included Coupang — where he's been a board member since 2010 — alongside BounceExchange, HowAboutWe, and Yipit. Further back he was President & CEO of Community Connect Inc., the company he founded that ran BlackPlanet.com, AsianAvenue.com, and MiGente.com — among the first social networking properties at scale, eventually acquired by Radio One. His career started in the Technology Investment Banking Group at Merrill Lynch after a BA in Economics from the University of Michigan. The through-line is a founder who built one of the internet's first social networks, turned operator-investor at LaunchTime, then institutionalized that bet into Primary — a fund that backed Jet.com (acquired by Walmart for $3.3 billion) and was on the ground floor of Coupang. He posts actively on LinkedIn about AI-native CRM, venture capital research, and emerging AI categories in legal, accounting, and insurance — and in 2026 appeared on a podcast with Nihal Mehta discussing AI strategy and on a panel covering GTM strategies in the AI age.

Company

Primary Venture Partners closed February 2026 with the launch of Fund V at $625 million — their largest fund by a wide margin, up from $150 million in Fund III — focused on seed investing with average check sizes of $5 million to $10 million and a plan to back 40 to 50 companies over three years. The fund is explicitly targeting AI and other fast-moving tech sectors, and the firm expects to make hundreds of hires, drive tens of millions of dollars in revenue pipeline, and support dozens of new financings for portfolio companies in 2026. That comes after a $98 million secondary sale to StepStone Group in November 2024, which the firm described as a signal of maturity and founder confidence. Primary has also backed The Biological Computing Co in a $25 million seed round for brain-inspired AI computing. The firm has built what it describes as one of the largest operator teams in seed VC — roughly 50 people including over 20 full-time platform operators, plus a network of over 200 technology operators providing hands-on support to founders.

Market

Primary competes in the New York City seed-stage VC market against Thrive Capital, Union Square Ventures, Lerer Hippeau, BoxGroup, FirstMark Capital, Greycroft, RRE Ventures, Insight Partners, and Tiger Global. The firm is ranked #133 in the 2026 global Power Law rankings with 11 unicorns and 1 decacorn in its portfolio, concentrated in fintech, e-commerce, and marketplaces. The AI boom has materially inflated early-stage round sizes across the board, which partly explains Fund V's scale — and the firm is leaning into operational support as its differentiated response to a more competitive seed market.

Network

Brad Svrluga is Ben's co-founder and co-GP at Primary — the two are frequently associated publicly and were jointly recognized on the Forbes Midas List. Tess Gutt leads Marketing & Networks at Primary Venture Partners and has engaged publicly around the firm's NYC network events alongside Cassie Young. Harrison Kratter is also on the Primary leadership team.

How they likely show up

Long tenure at Primary since founding in 2015 → thinks in fund cycles and multi-year portfolio arcs, not quarterly deal velocity.
Founded Community Connect in the 1990s, ran LaunchTime, then co-founded Primary → pattern of building institutions from scratch; likely has little patience for inherited process he didn't design.
Active LinkedIn poster on AI-native CRM, legal/accounting AI, and emerging categories → comfortable sharing a thesis publicly before it's consensus; probably responds well to being challenged on it.
Hybrid role type (founder-operator turned GP) alongside a platform-heavy fund model → likely evaluates founders on operational specifics, not just vision.
Coupang board member since 2010, well before the IPO → comfortable with very long hold periods and conviction-based commitment.
Fund V at $625 million versus Fund I at $60 million → has managed a 10x scaling of the firm; attuned to organizational complexity and what breaks at each stage.

Conversation tips

→ Reference his Community Connect days specifically — BlackPlanet and AsianAvenue were genuinely among the first social networks, and he rarely gets credit for that arc relative to later-wave founders.
→ Ask about the Coupang board seat — he's been there since 2010, which spans the entire Korean e-commerce story, and it's likely a rich reference point for how he thinks about founder support over time.
→ He posts about AI-native CRM and AI in professional services (legal, accounting, insurance) — come with a specific thesis or question in those categories rather than a general AI opener.
→ Don't treat him as a pure financial investor; the platform model with 50+ people is central to Primary's identity — he'll want to talk about what operational support actually means in practice.
→ He has a founder background, not a pure VC background — framing questions around what he learned building and selling Community Connect will resonate more than fund-mechanics questions.

Toolbox

Openers

Open on the Fund V launch — $625 million at seed stage is a striking scale-up from $60 million in Fund I, and asking how the firm's investment thesis has had to evolve to deploy that much at seed is a genuinely interesting question he'll have a prepared answer for.
Bring up Altis — he founded a company building research infrastructure for the venture capital market, which is an unusual bet for a sitting GP to make; it signals something specific about how he thinks the industry works and what's broken.
Reference his LinkedIn post on AI-native CRM — he asked 70 CRM buyers a direct question and shared what he found; leading with that specific post shows you've read his actual thinking, not just his bio.

Discovery questions

You backed Jet.com early and were on Coupang's board from 2010 — what did those two bets teach you about the difference between a company that looks like a category winner and one that actually becomes one?
Fund V's $625 million is roughly 10x Fund I — at what point did the platform model with 50+ operators stop being a differentiator and start being a necessity to deploy that kind of capital responsibly?
You're posting actively about AI in legal, accounting, and insurance — what's the specific unlock you think is happening in those verticals right now that makes the timing different from five years ago?

Avoid

Don't open with generic observations about New York's tech scene being 'on the rise' — he's been building in NYC since the 1990s and has spoken and written about that arc extensively; it'll read as homework you didn't do.
