Josh Wolfe

Who they are

Josh Wolfe is Co-Founder and Managing Partner of Lux Capital — co-founded Kurion (nuclear waste cleanup) and Variant Bio (2018), and chairs Coney Island Prep, the first charter school in Coney Island.

Person

Josh Wolfe graduated from Cornell with a B.S. in Economics and Finance in 1999, then went straight into Wall Street — investment banking at Salomon Smith Barney and Merrill Lynch, and capital markets work at Prudential Securities covering financial futures, options, and government strategy. In 2000 he left banking to co-found Lux Capital with Peter Hébert and Robert Paull, starting from zero AUM and building it into a $7 billion firm over 25 years. Beyond the fund itself he's been a hands-on company builder: founding investor and board member at Kurion (nuclear waste cleanup), co-founder of Variant Bio in 2018 with scientists Kaja Wasik and Stephane Castel, and co-founder of Coney Island Prep, the first charter school in Coney Island, where he chairs the board. The through-line is a conviction that science precedes wealth — he's been betting on that thesis since before it was fashionable in VC. He writes at Forbes, edits the Forbes/Wolfe Emerging Tech Report, posts actively on X (@wolfejosh), and has testified before Congress multiple times on emerging technology; he's also a trustee of the Santa Fe Institute since 2015 and has lectured at MIT, Harvard, Yale, Cornell, Columbia, and NYU. He's appeared on Odd Lots (2025), the Knowledge Project (2024 — 'Human Advantage in the World of AI'), Fortune (2024, on the Lux Labs launch), The Portal with Eric Weinstein, and a long roster of other podcasts where he consistently argues the next decade of value creation is physical, capital-intensive, and legally constrained — not a coding sprint.

Company

In January 2026, Lux closed Fund IX at $1.5 billion — the firm's largest fund ever, oversubscribed beyond its initial $1.25 billion target — bringing total AUM to $7 billion. That same month Lux led a $350 million round for Erebor and co-led a $200 million-plus round for Anduril Industries, whose secondary valuation stands at $30.5 billion. In 2024, Lux formalized its company-creation practice as Lux Labs, and in May 2025 it launched the Lux Helpline to support academic researchers facing federal funding cuts — a pointed signal about where Wolfe sees the talent and IP pipeline drying up. The portfolio saw two major exits in 2025: Chronosphere acquired by Palo Alto Networks for $3.35 billion in November, and Matterport acquired by CoStar Group for $2 billion in February. Zach Iscol joined as a Venture Partner in 2026, joining retired four-star General Tony Thomas and former diplomat Brett McGurk on a team that now has 44 full-time professionals.

Market

Lux operates at the intersection of deep tech and defense VC, competing directly with Founders Fund, Khosla Ventures, and In-Q-Tel for deals in AI, biotech, aerospace, autonomous systems, and dual-use defense technology. The firm's thesis is being validated by macro tailwinds: venture investment in aerospace and defense reached $21.4 billion across more than 300 deals in 2025, and reduced federal R&D spending is pushing scientists and IP into the private sector — directly into the arms of firms like Lux. Regulatory scrutiny from the FTC and DOJ is reshaping exit dynamics, with license-and-acqui-hire structures (pioneered by Microsoft with Inflection, Amazon with Adept) becoming a new exit path alongside traditional M&A and IPO, while the VC market itself bifurcates toward specialist managers.

Network

Wolfe's closest professional anchor is Peter Hébert, his co-founder and co-managing partner at Lux Capital since 2000. He shared a board seat with Bill Gates at Kymeta, a satellite antenna company. He has been in dialogue with Annie Duke on contrarian decision-making in venture, and maintains advisory relationships with US Congress and the White House on technology policy.

How they likely show up

Co-founded Lux Capital in 2000 and has run it for 25+ years → thinks in decade-long arcs; not interested in quarterly narratives.
Active on X (@wolfejosh) and regular podcast circuit (Odd Lots, Knowledge Project, Portal, Invest Like the Best) → comfortable being a public intellectual, likely expects his counterpart to have engaged with his published views before the meeting.
Multiple US Congress testimonies on emerging tech → used to translating frontier science into policy-accessible language; can code-switch between scientist, investor, and policymaker registers.
Co-founded Kurion, Variant Bio, and Coney Island Prep alongside running a $7B fund → high agency, builds where he sees a gap rather than waiting for someone else to do it.
Santa Fe Institute trustee since 2015, lectured at MIT/Harvard/Yale/Cornell/Columbia/NYU → draws intellectual community from complex-systems and scientific research worlds, not just the Sand Hill Road circuit.
Launched the Lux Helpline in May 2025 to support researchers facing federal funding cuts → responsive to macro disruptions in real time; likely to have a current, considered view on whatever policy or science story is live.

Conversation tips

→ Reference a specific thesis he's stated publicly — e.g. his 2025 Odd Lots appearance on AI and Silicon Valley's 'broken social contract,' or his Fortune interview on Lux Labs — to signal you've done the work.
→ Come with a point of view on physical vs. software value creation; his core thesis is that the next decade rewards capital-intensive, physically constrained businesses, and he'll engage harder with someone who pushes back intelligently than with someone who just agrees.
→ Ask about the Lux Labs model specifically — creating companies from scientific ideas rather than backing founders who come in the door — because it's the newest structural bet and he'll have strong opinions on what works.
→ He values scientific depth, so if you have any background in hard science, engineering, or defense technology, surface it early — it's the common language at Lux.
→ Don't treat him primarily as a financier; he thinks of himself as a science-to-commerce builder first, and the fund is the vehicle for that, not the identity.

Toolbox

Openers

Open on the Lux Helpline launch (May 2025) — he created a direct support line for academic researchers losing federal funding, which is a pointed operational bet that the talent and IP pipeline is shifting private right now.
Reference the Lux Labs formalization in 2024 and the Fortune interview where he discussed 'making science fiction reality' — it's the newest structural evolution of the firm and he went on the record about the strategy.
Bring up his 2025 Odd Lots episode on AI and 'the breaking of Silicon Valley's social contract' — it's recent, it's specific, and it signals you're tracking his current public thinking rather than his greatest hits.

Discovery questions

Lux Labs has now created more than 20 companies since founding and formalized that in 2024 — what does the company-creation model look like operationally, and how does it differ from a traditional incubator?
You've argued the next decade of wealth creation is physically constrained and capital-intensive — how does that thesis change how you underwrite a deal, given that most VC fund structures were built for software-style capital efficiency?
With retired General Tony Thomas, Brett McGurk, and Zach Iscol all joining as Venture Partners, Lux has built an unusually deep government and defense network — how does that network actually move the needle for a portfolio company trying to navigate defense procurement?

Avoid

Don't pitch or discuss software-only businesses or generic AI productivity tools — his entire public thesis is a bet against pure-software value creation and toward physical science, and he will find it an immediate signal that you haven't done the reading.
