Technical conviction
We recognize hard-won technical truth before the market has a name for it.
Capital is a commodity. Attention is not.
We back technical founders early, then help make their companies impossible to ignore.
01 / The Anti Fund Edge
See the future early. Make it impossible to ignore.
Capital can fund a company. Attention recruits talent, earns trust, and shapes categories. Anti Fund pairs technical judgment with uncommon reach to help breakthroughs become defining companies.
Earned attention
We help the right talent, customers, partners, and public understand why the company matters.
Founder leverage
We stay close when product, narrative, talent, and timing can compound the mission.
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.

05 / How We Work
Conviction is only the beginning.
We work directly on the decisions that determine what happens next.
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.
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
More founder references
"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
"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."
Abraham Othman
Former Chief Data Scientist, AngelList & CIO, Strawberry Tree Management Company LLC
