Cosmos Ventures Launches $77.6M Fund I for AI-Era Founders

TL;DR

Brendan McCord and Matt Mandel have launched Cosmos Ventures with a $77.6 million Fund I to back what they call "philosopher-builders" — founders who treat the normative questions AI raises as product decisions, not academic debates. The fund grew out of Cosmos Institute, the two-year-old nonprofit McCord founded to bring philosophers and AI builders into the same room, and it's already deployed into AIUC, Prime Intellect, and the now-acquired Workshop Labs. It matters because it's a genuinely differentiated sourcing model: a research and fellowship community that produces its own deal flow before a fund ever gets raised around it.

Key Takeaways

The fund is downstream of two years of community-building, not a cold start. Cosmos Institute has been running grants, fellowships, and courses since 2024, and several Fund I portfolio companies — including AIUC and Prime Intellect — trace directly back to people who found the Institute through its syllabus, reading groups, or Oxford seminar. That's a sourcing advantage most new funds spend years trying to build.

One portfolio company has already been acquired. Workshop Labs, co-founded by Luke Drago and Rudolf Laine, was acquired by Thinking Machines Lab in 2026 — a fast, credible outcome for a firm just now announcing its debut fund, and a data point that the thesis-first sourcing model can produce real exits, not just interesting theory.

The LP base signals more than capital. Reid Hoffman, Fred Wilson, and Micky Malka are among the more thoughtful long-horizon technology investors of the last two decades; Stand Together and the Astera Institute bring philanthropic and scientific-research networks that a typical seed fund's cap table doesn't include. That combination suggests Cosmos is positioning itself as much as an intellectual node as a capital source.

McCord's Pentagon and submarine background is doing real thesis work, not just color. Building the Department of Defense's first applied AI organization means McCord has firsthand experience with the exact problem the fund is underwriting: institutions forced to make consequential, values-laden decisions about AI before the theory has caught up. That's a rare credential in a venture landscape dominated by product and growth backgrounds.

Why This Fund Matters

Most new venture funds spend their first eighteen months building a deal-sourcing pipeline from scratch. Cosmos Ventures skipped that step by running the pipeline first: Cosmos Institute has spent two years funding a hundred-plus grants a year, running fellowships, teaching courses, and convening a philosophy-and-AI seminar at Oxford, and several of Fund I's earliest bets came directly out of people that community surfaced. Rune Kvist, a co-founder of AIUC, reportedly found the Institute through its syllabus on the intellectual origins of technology and turned it into a reading group in San Francisco before Cosmos backed his company. That's a fundamentally different sourcing motion than cold outbound or warm-intro deal flow, and it's difficult for a fund without an equivalent multi-year community investment to replicate quickly.

The underlying thesis — that AI is forcing builders to make the kind of foundational, values-laden decisions that philosophers have debated in the abstract for centuries — is a genuinely underserved lens in a venture market that's mostly organized around technical capability and go-to-market speed. Questions about what AI assurance should look like, who gets to shape the norms around agent behavior, or how AI products should preserve rather than erode individual autonomy aren't hypothetical for Cosmos's portfolio; they're the literal product spec. AIUC is building certification and insurance infrastructure to make AI agents safe to adopt commercially — the closest modern parallel to how mutual insurance made electricity a viable consumer technology a century ago. Workshop Labs was built explicitly to counter what its founders termed "the intelligence curse" — the risk that AI leaves ordinary people economically irrelevant and politically powerless — by building models tailored to each user rather than models that simply automate people out of the loop.

Prime Intellect's inclusion is a useful signal about how far this thesis extends beyond safety-adjacent categories. It's building open infrastructure for training, deploying, and improving frontier models — squarely in the infrastructure race that's absorbed the majority of AI venture capital over the past two years. Cosmos invested alongside Founders Fund, and Radical Ventures has since led a $130 million Series A with NVIDIA's participation — evidence that "philosopher-builder" framing isn't limiting Cosmos to a narrow safety niche; it's a lens the firm is applying across frontier infrastructure, assurance, consumer AI, and education alike.

The LP roster reinforces that this is a fund built for staying power rather than a quick opportunistic raise. Reid Hoffman and Fred Wilson have each backed multiple venture cycles' worth of category-defining companies; Micky Malka's fintech and Latin America networks and Stand Together's philanthropic infrastructure extend Cosmos's reach well past a typical Silicon Valley seed fund's network. That's a notable roster for a $77.6 million debut vehicle, and it suggests Cosmos was able to raise on the strength of the Institute's two-year track record rather than a cold pitch.

The Team

Brendan McCord is General Partner and co-founder of Cosmos Ventures, and separately serves as founder and Chair of Cosmos Institute. His path to venture capital runs through the U.S. Navy submarine force — 610 days underwater, including extended stretches beneath Arctic ice — followed by founding the Department of Defense's first applied AI organization and authoring the Pentagon's first AI strategy. In the private sector, he was founding CEO of two AI startups that were acquired for a combined $400 million, and per his own public biography he also served as President of an AI holding company that generated billions in investor returns. He holds degrees from MIT and Harvard Business School and is a Visiting Fellow at St Catherine's College, Oxford, where he co-teaches a seminar on philosophy and AI.

Matt Mandel is General Partner and co-founder alongside McCord. He previously worked as an investor at Union Square Ventures, joining after a stint at vertical-farming startup AeroFarms, where he served as Chief of Staff and worked on corporate development and expansion strategy. He studied philosophy and computer science at Harvard, where — per Cosmos's own announcement — he won the university's prize for the best undergraduate thesis in moral, social, and political philosophy. McCord and Mandel say they developed the Cosmos Ventures thesis together before formalizing the fund.

Early Portfolio

AIUC (Artificial Intelligence Underwriting Company) is building certification and insurance infrastructure meant to make AI agents safe enough for enterprises to adopt at scale. Co-founder Rune Kvist was Anthropic's first product and go-to-market hire; NFDG led the company's seed round and Ribbit Capital led its Series A, with Cosmos investing early. Prime Intellect is building open infrastructure for training, deploying, and continually improving frontier AI models. Cosmos invested alongside Founders Fund; Radical Ventures has since led a $130 million Series A with NVIDIA participating. Workshop Labs, founded by Luke Drago and Rudolf Laine — authors of an essay on AI's risk of economic and political disempowerment — built AI systems tailored to individual users' knowledge, taste, and values; the company was acquired by Thinking Machines Lab in 2026. Cosmos has also backed an education company that remains in stealth.

What This Means for Founders

If your company is grappling with a genuine normative question — who should set the rules for how an AI product behaves, what obligations a platform owes the people who depend on it, how to preserve human agency inside an AI-mediated workflow — Cosmos is explicitly built to fund that kind of founder at the earliest stage, before the business model and even the company's values are fully settled. That's a different pitch than "we're faster/cheaper with AI," and founders should lean into the institution-building framing directly rather than retrofitting it onto a conventional pitch.

Given the fund's size and stage focus, expect meaningful founder access to McCord and Mandel directly rather than a large platform team, plus a natural bridge into the Cosmos Institute's fellowship, grant, and research network if that's useful for recruiting or credibility with technical co-founders. Founders can reach the firm directly at founders@cosmosventures.com.

Fund Momentum Take

We think the community-first sourcing model is the most exportable idea in this raise, more so than the philosophy framing itself. Any fund founder with a genuine, multi-year content and community engine — not a newsletter thrown together to justify a raise, but something like Cosmos Institute's grants-and-fellowships infrastructure — can plausibly generate the kind of proprietary, pre-vetted deal flow that took Cosmos two years to build before it ever needed to write a check. Expect more solo-GP and small-partnership funds to try to replicate this playbook, with much lower success rates than Cosmos has had, because the Institute's credibility took real time and capital to establish.

The risk sits in scope creep. "Philosopher-builder" is broad enough to justify almost any AI-adjacent bet, from safety infrastructure to consumer products to education — which is exactly the kind of framing that's hard to hold a fund accountable to over a multi-year vintage. The early portfolio spans frontier infrastructure, assurance/insurance, consumer autonomy tools, and education, which is either evidence of genuine thesis breadth or evidence that the filter is looser than the branding suggests. The Workshop Labs acquisition this early is a good sign either way.

Our bet: funds that pair a real community-and-research engine with genuine domain credibility — McCord's Pentagon and national-security AI experience is not easily replicated — will keep outperforming funds that adopt similar "mission-driven" branding without the multi-year infrastructure behind it. Cosmos looks like the former, and the two-year track record backing Fund I is the reason to believe it.
