Jeff Clavier

Who they are

Jeff Clavier is Founding Partner of Uncork Capital — started the firm in 2004 with his wife as his first LP, backed Fitbit, Eventbrite, and Postmates from seed, and owns a winery in Walla Walla, Washington.

Person

Jeff Clavier took an MS in Computer Science (with a degree in Distributed Computing) from Université Paris Descartes (Paris V), then built his early career as a developer and product/development leader at Effix, a fintech startup in France, before moving to Reuters where he rose to CTO and ran U.S. operations as General Partner at Reuters Venture Capital. He made the leap to San Francisco and in 2004 founded SoftTech VC — now Uncork Capital — with his wife as his first LP and an initial fund under $1M; by 2007 he'd raised over $15M, and the firm has grown through eight seed funds since. The portfolio reads like a greatest-hits of consumer and B2B internet: Fitbit, Eventbrite, Postmates, Poshmark, SendGrid, GPTZero — over 275 companies backed, 10 unicorns, 4 IPOs, 116 acquisitions. He started a blog called 'Software Only' in 2004, covering social media, search, online communities, and investing — one of the earlier VC bloggers in the valley. As of May 2025, he stepped back from the Managing Partner role to focus on frontier tech investing, with Andy McLoughlin taking over day-to-day firm leadership. The through-line is a French engineer who bet early on the U.S. seed market before institutional seed was a recognized category, and then stayed put while the category grew around him — he's also launched a winery in Walla Walla, Washington, a natural extension of a long-documented wine-collecting habit.

Company

In May 2025, Uncork Capital closed $300 million in new capital — $225 million for its Uncork VIII seed fund and $75 million for its Plus IV growth fund — with plans to deploy both over the next three years. The same month, Andy McLoughlin became sole Managing Partner, with Jeff Clavier stepping back from that role to concentrate on frontier tech investing. The firm's investment strategy continues to center on leading seed rounds across B2B software, developer tools, and infrastructure, with significant follow-on reserves. As of April 2026, the portfolio spans over 275 companies, including 10 unicorns, 4 IPOs, and 116 acquisitions, with active investments across Enterprise Applications, Consumer, and High Tech.

Market

Uncork Capital is one of Silicon Valley's most established seed-stage firms, having operated continuously since 2004 — a vintage that predates most of today's dedicated seed funds. It competes in a crowded early-stage market alongside other seed specialists, though no single named direct competitor stands out in the available information; its differentiation has historically been check-writing speed, founder-friendly terms, and follow-on reserves through the Plus funds. Co-investors have included SV Angel, and its portfolio exits — Fitbit, Eventbrite, Intuit-backed companies — signal meaningful co-investment relationships with larger growth funds.

Network

Jeff's closest professional circle is the Uncork partnership: Andy McLoughlin (now sole Managing Partner), Amy Saper, Susan Liu, Tripp Jones, and Stephanie Palmeri are all partners at the firm. He has served on the boards of the National Venture Capital Association and VentureForward, NVCA's nonprofit arm, giving him institutional reach into the broader U.S. VC policy community.

How they likely show up

Founded Uncork in 2004 and ran it for over 20 years → thinks in decades-long fund cycles, not annual sprints; unlikely to be moved by short-term market noise.
Started as a developer and CTO before becoming an investor → probably reads technical pitches at a level most generalist VCs don't; founders can go deep on architecture with him.
Blog 'Software Only' launched in 2004, covering investing and internet trends → early adopter of public thinking; comfortable sharing views and likely respects founders who do the same.
No formal investment committee at Uncork — decisions are partnership-driven → consensus-oriented internally, but partnership meetings likely move fast without a bureaucratic approval layer.
Stepped back from Managing Partner in May 2025 to focus on frontier tech → actively repositioning his attention; he's in exploration mode right now, not execution mode.
Long-tenure signal (20+ years at the same firm) → values continuity and relationship depth over deal velocity; reputation maintenance is core to how he operates.

Conversation tips

→ He's a technical founder turned investor — you can go deep on product architecture or engineering decisions and he'll engage, not glaze over.
→ He started 'Software Only' in 2004, one of the early VC blogs — reference a specific post or the blog's era if you want to signal you've actually done the work.
→ He's in a transition moment: stepped back from Managing Partner in May 2025 to focus on frontier tech. Ask what 'frontier tech' means to him right now — it's the live question on his mind.
→ He backed companies from seed when no one called it 'seed investing' — he has strong pattern-recognition opinions about what seed-stage behavior actually looks like. Founders who are too polished may read as late-stage pretenders to him.
→ He owns a winery in Walla Walla — it's a genuine passion, not a talking point. If wine comes up naturally, it's a real connection point, not small talk.

Toolbox

Openers

Open on the May 2025 step-back: he handed the Managing Partner role to Andy McLoughlin and said he's refocusing on frontier tech — ask what that shift looks like in practice, because it's the freshest and most personal move in his recent record.
Reference 'Software Only,' his blog started in 2004 — one of the earliest VC blogs in the valley, covering social media, search, and online communities before those were VC categories. It signals you know his history predates the SoftTech brand.
Mention the Walla Walla winery — he's a documented eclectic wine collector who turned the hobby into an actual vineyard. It's a concrete, named detail from his own firm's bio page, and it opens a real conversation rather than a rehearsed one.

Discovery questions

You backed Fitbit, Eventbrite, and Postmates from seed before 'seed investing' was a recognized category — how has the seed market changed in ways that make it harder, not easier, to find the next one of those?
You stepped back from Managing Partner to focus on frontier tech — what does 'frontier tech' mean to you specifically right now, and how different is that diligence process from the B2B software playbook Uncork is known for?
Uncork has no formal investment committee — decisions go through the partnership directly. As the firm has grown to five partners and Fund VIII, how do you keep that process fast without losing conviction alignment?

Avoid

Don't treat his French/European background as just a biographical footnote and pitch it back to him as insight — he's been operating in Silicon Valley since 2004 and his frame of reference is entirely the U.S. seed market.
