Jeff Fluhr

Who they are

Jeff Fluhr is Venture Partner at Craft Ventures — co-founded StubHub in 2000 and led it as CEO through its sale to eBay in 2007.

Person

Jeff Fluhr took his BS in Engineering from Penn in 1996, spent a few years as an analyst at The Blackstone Group, then dropped into Stanford GSB before leaving to co-found StubHub in 2000 — an online ticket marketplace he built and ran as CEO until eBay acquired it in 2007. After the exit he did a stint as an angel investor, then co-founded Spreecast in 2011, a social video platform he led as CEO until 2017. He joined Craft Ventures in October 2018 as a Partner, initially in a full partner role before transitioning to Venture Partner by 2025. The through-line is operator-first: he built two companies from scratch, took one through a major acquisition, and now backs founders from that same seat of experience. Possibly — his move from full Partner to Venture Partner reflects a deliberate step back from day-to-day fund operations toward a more selective, portfolio-support role.

Company

Craft Ventures' most recent headline is its April 2026 lead on a $30 million growth round for ComfyUI at a $500 million post-money valuation — a pointed bet on AI infrastructure orchestration. The same month the firm led a round for Hyfix, a U.S. startup building an autonomous-systems chip for drones, squarely aimed at domestic supply chain resilience as an alternative to DJI's dominance. In late 2025 the firm led a $120 million Series B for agentic access management platform Oasis Security and a $33 million Series A for AI-driven cybersecurity firm Daylight Security. The fund base underpinning all of this is the $1.32 billion closed across Craft Ventures IV and Growth II in November 2023, giving the firm capacity to lead at both early and growth stages.

Market

Craft Ventures sits in a crowded Bay Area VC field competing directly with Sequoia, Andreessen Horowitz, Accel, Lightspeed, Greylock, Benchmark, and Founders Fund, differentiating on an operator-founder identity — David Sacks and the partner roster all come from the builder side. The firm manages over $3.5 billion in assets across more than 350 portfolio companies, with 26 unicorns, 15 IPOs, and 31 acquisitions. Geopolitical pressure from US-China trade tensions is visibly shaping deal flow toward domestic AI infrastructure, dual-use defense technologies, and national security plays — a theme evidenced by both the Hyfix drone chip investment and the space commerce exposure via Xona Space Systems.

Network

No direct edge data is available for Jeff Fluhr's network. At Craft Ventures his partners include David Sacks (Founder and General Partner), Mark Woolway (President), Brian Murray (Partner & COO), and Michael Robinson (Partner, Head of Investment Team). His earlier career at AngelHub placed him alongside early-stage founders in the San Francisco angel community.

How they likely show up

Co-founded and ran StubHub as CEO from 2000 to the 2007 eBay sale → he has lived through the full founder lifecycle, from zero to acquisition; he'll instinctively think about exit optionality and buyer readiness.
Co-founded Spreecast in 2011 after a major exit, rather than staying in investor mode → high agency, prefers building to watching; unlikely to tolerate passive portfolio relationships.
Moved from full Partner to Venture Partner at Craft Ventures → probably works best in a focused, selective engagement model rather than across a broad portfolio with constant deal cadence.
Engineering undergrad at Penn, then Blackstone, then Stanford GSB → analytical baseline with a finance layer; he can read a model but led with product and operations, not finance, throughout his career.
Possibly — no detectable public writing signal → he is unlikely to be a 'thought leader' type; conversations will be direct and deal/company-focused rather than conceptual.

Conversation tips

→ Come in with a specific operational question — he ran a marketplace and a social video company; he responds to founder-level specifics, not high-level strategy.
→ The StubHub story is a genuine reference point, not a name-drop: ask about what the eBay acquisition process taught him about building for acquirability.
→ Don't conflate his Venture Partner title with a limited role — he has been at Craft since October 2018 and carries deep firm context; treat him as a substantive voice on the portfolio.
→ If you're in B2B SaaS, AI infrastructure, or cybersecurity, those are live investment themes — come with a concrete thesis, not a category pitch.

Toolbox

Openers

Open on the Hyfix investment — Craft just led a round for a U.S. drone chip startup explicitly positioned as a domestic alternative to DJI, which is a sharp geopolitical bet; ask what he's seeing in dual-use defense deal flow right now.
Reference the ComfyUI lead in April 2026 — a $30 million growth round at a $500 million valuation for an AI infrastructure orchestration tool is a specific thesis about where AI value accrues; it's a good entry into how he thinks about AI infrastructure versus application layer bets.
Bring up Spreecast — he built a social video platform from 2011 to 2017, before live video became a category; it's an underexplored part of his story that signals he's willing to bet early on format shifts.

Discovery questions

StubHub was acquired by eBay in 2007 — what did running a marketplace through an acquisition process change about how you evaluate marketplace founders today?
Craft led both Oasis Security's $120 million Series B and Daylight Security's $33 million Series A in the same period — how do you think about the right entry stage for cybersecurity companies given how fast the AI-agent threat surface is moving?
You went from full Partner to Venture Partner at Craft — how has your day-to-day engagement with portfolio companies changed, and what does a Venture Partner role actually look like in practice at an operator-led fund?

Avoid

Don't pitch broad 'marketplace' or 'video platform' analogies to StubHub or Spreecast without doing the work — he lived both companies in detail and will immediately probe whether you actually understand what made each one specific.
