Venture I
$30M
Pre-seed & seed
First conviction in technical founders before the market has a clean category or consensus view.
Anti Fund / Venture + Growth
Capital is commodity. Attention is not.
We back technical founders from first check through category scale, pairing concentrated capital with the attention, judgment, and access that compound company value.
01 / Current Platform
One firm. Two mandates. The same conviction at different points on the curve.
Venture I backs technical founders at formation. Growth I keeps Anti Fund in the room as category leaders scale. Together they form a barbell: early ownership on one side, concentrated growth on the other.
Growth I
$100M
Growth & pre-IPO
Concentrated positions in companies turning technical advantage into institutional-scale value.
Firm AUM
$180M+
As of June 2026
Growth I closed oversubscribed in June 2026. The current mandate centers on AI, robotics, defense, energy, semiconductors, manufacturing, and frontier infrastructure, with selective software and consumer investments where product and distribution reinforce each other.
02 / Investment Thesis
Conviction before consensus.
Axiom I
The best founders are anti before they are obvious.
Axiom II
Technical truth creates the edge. Distribution compounds it.
Anti Fund looks for companies that can define the standard in AI, robotics, defense, energy, manufacturing, semiconductors, software, and selective consumer markets. The sector matters, but the inflection matters more.
At the earliest stage, taste and non-consensus insight dominate. At growth, the test becomes technical durability, customer pull, and the ability to turn an early advantage into an institution.
What We Look For
Technical edge
A product, model, system, or operating capability that capital alone cannot copy.
Founder obsession
Builders who have lived with the problem long enough to see around corners.
Customer urgency
A painful need and evidence that users will change behavior now, not someday.
Non-consensus timing
A precise view of what changed before the market has settled on a category.
Compounding attention
The ability to turn trust and relevance into customers, talent, and financing.
Category ambition
A credible path to define the market standard rather than join the segment.
03 / Select Investments
The thesis, made concrete
Anti Fund backs technical advantage early and follows conviction through scale.
The firm invests when technical edge, product judgment, or cultural timing is early enough to matter. Stage is flexible; the standard is not.
The portfolio spans AI, defense, robotics, energy, semiconductors, fintech, software, and culture-native consumer markets.
Early conviction
Founder references document commitments before company formation and first-investor support.
Growth I
$100M for concentrated positions in companies moving from technical edge to institutional scale.

04 / How We Work
Capital only matters if it changes the company's odds.
Anti Fund works directly on the decisions with compounding consequences. The job is not to perform helpfulness. It is to create useful pressure, access, and signal when the next move matters.
01
Product & positioning
We pressure-test what to build, what to cut, and what has to be true for customers and the market to care.
02
Customers & distribution
We turn product truth into market pull through customer sequencing, partner access, launch timing, and narrative discipline.
03
Capital & talent
We help create leverage for financing and senior hiring: the right people, in the right order, with a reason to move now.
04
Consequential decisions
We stay close through product resets, board pressure, financing forks, and the operating choices that change the company's trajectory.

06 / Founder References
What founders say after the wire.
The useful measure of a venture partner is the work founders can name: customers closed, executives recruited, rounds shaped, and difficult decisions made with better signal.
Operating Evidence
"Geoff was one of the earliest investors for both Ramp and Paribus, and he is a trusted advisor and a key strategic sounding board. With Ramp, Geoff has directly boosted our topline revenue and growth by introducing us to and helping us close key customers and hire superstar executives. Geoff is on my shortlist to bring onboard for any company I'm involved with."
CEO & Co-founder, Ramp
"Geoff was one of our first investors and committed to backing Chronosphere before our company was even set up. He is incredibly networked in tech and investor circles and has been a key strategic thought partner. He is one of those rare humans that wields deep technical, product, and business expertise."
CTO & Co-founder, Chronosphere
"Thanks for all of support! Couldn't ask for a better partner."
CEO, Metis
"Geoff is an incredible visionary with sharp intuition. As our earliest investor, he has consistently given advice that proves true time and time again. His strong connections with the most influential minds in Silicon Valley are the exact fuel that early-stage founders can only dream of. Essentially, he brings his A-game. Founders just need to bring theirs."
Gun Choi
CEO & Co-founder, Linedot
"Geoff and Steve are one of the best partners to have as a founder. They are incredibly well connected - Geoff introduced us to Karim from Ramp who became our investor. Steve is always responsive, pushing us to think in unconventional angles. I would highly recommend Anti Fund to any exceptional founders."
CEO & Co-founder, Pensive
"Anti Fund was our first investor and a key sounding board for strategic decisions. They're direct and candid when it matters, skipping unnecessary niceties in favor of clear, actionable support. Geoff has been my most valuable investor from the start, pushing me towards market-validated technical verticals and a business development approach focused on generating meaningful signal before noise."
CEO & Co-founder, Efference
Independent validation
Outside validation matters when it comes from people who have seen the data, not just the brand.
"No other GP on the AngelList platform - out of hundreds of qualifying investors - beats the Anti Fund along both of these axes. It follows that Geoff and Jake may be able to justify a claim to being the "best investors on AngelList", in the sense that there's no other GP that dominates them along the data-driven axes that we believe can help to predict future investment performance."

The thesis is public. So is the work.
Conversations and field visits show the thesis in practice: how Anti Fund thinks, where the team spends time, and which technical shifts matter before they become consensus.

Appendix A / FAQ
Questions founders and investors ask.
Venture I backs technical founders at pre-seed and seed. Growth I makes concentrated growth and pre-IPO investments. The current focus is AI, robotics, defense, energy, semiconductors, manufacturing, frontier infrastructure, and selective software and consumer technology.
Anti Fund closed its oversubscribed $30M Venture I in December 2025 and its oversubscribed $100M Growth I in June 2026. Firm assets under management exceed $180M.
Most firms choose between technical underwriting and distribution. Anti Fund combines both. Attention is not promotion for its own sake; it is useful when it helps a company recruit exceptional people, earn customer trust, win financing, and become legible before consensus catches up.
We stay close during consequential moments: product launches, financing rounds, senior hires, customer introductions, narrative resets, board pressure, and strategic forks where the next decision changes the company.
We invest between $250K-$30M+. We are comfortable both leading and participating.
Growth I closed oversubscribed at $100M in June 2026. We are not actively fundraising, but investors interested in future funds can contact ir@antifund.com.
