Dave Fontenot's HF0 is a 12-week coding retreat that removes all distractions so founders can enter a state of flow. The real value is not what you build, but the permanent shift in knowing what's possible. No market view, but it bets on elite founders. Key names: Alex Atala (OpenSea, his next company started at HF0), Andrew D'Souza (ClearBank, same), Guillermo Rauch (Vercel, gave a talk at HF0).
Dave Fontenot's HF0 is a 12-week residency program designed for serial entrepreneurs, inspired by global monastic experiences. The program accommodates 10 groups of engineers at a time, relocated to a dedicated residence in San Francisco, where all daily tasks are handled, ensuring the team's sole f
Dave Fontenot, founder of HF0, distilled a “subtraction philosophy” from his global monastery experiences — placing serial entrepreneurs in a 12-week fully managed residency environment, removing all distractions, allowing them to enter a sustained flow state and resolve internal obstacles. Core thesis: The true value of the residency model lies not in “what you built in 12 weeks,” but in the permanent shift in your mind of “what you know has become possible” — a shift that will continue to unlock potential for decades to come.
Dave Fontenot argues that HF0 and the monastery share the same core mechanism: true power lies not in "adding more," but in "taking away."
From his first 10-day Vipassana meditation retreat, Dave observed a key cycle: "In 10 days, almost everyone experiences a breakdown and a breakthrough." Seven days is not enough—some people only break down by day 7, and if they stop there, there is no room for breakthrough. Ten days ensures the vast majority complete the full cycle.
He directly transplanted this mechanism into the programming context. He recalls his experience writing code in the basement of the University of Michigan: "You don’t get stuck, because you have 'relatively unlimited time' to just sit there and let the problem solve itself." Hackathons gave him a weekend version of this experience, but Dave’s ultimate vision was to create a "lifestyle"—like throwing a Poké Ball to create a "bubble" that allows you to be fully immersed and connect with the matrix to write code.
Mechanism Breakdown: What the monastery and HF0 share is "subtraction"—not adding experiences, but removing all the trivial distractions in life that can be noticed. In a monastery, you don’t need to worry about time, because the bell tells you when to eat. At HF0, the Dao is similar: there are rotating cooks, a bell, laundry service, and room cleaning. "You don’t even notice these things—because they are handled before they become distractions."
Dave Fontenot believes that 12 weeks is the "magical duration" of a residency — a constraint that fits the real-life realities of founders and their families better than any rational model.
Dave admits candidly: "12 weeks is the longest period we can convince a founder's partner to accept." The average founder is between 28 and 35 years old, most have partners, and some already have children. 12 weeks sounds more acceptable than "three months."
But the internal logic of 12 weeks is equally important: "Once you enter weeks 3, 4, and 5 and get into the flow state, many people hope this state can last forever." Having a clear end date actually makes the period more urgent. HF0's data also supports this duration: one team launched their app only a few weeks before entering the residency, but achieved explosive growth during the residency — "ranked #14 on the App Store, with $7 million in annualized revenue."
Deduction: Dave believes that, in the long run, the ideal residency would be longer or even indefinite, but 12 weeks is the optimal solution under current constraints. After founders leave, about half of them try to "replicate HF0" in their own lives — indicating that this flow state itself is addictive, and proving that the power of subtraction can be internalized as a lifestyle.
Falsification Condition: If the "crash-through" cycle cannot be completed within 12 weeks, or if founders completely fail to maintain any flow habits after leaving, then this duration assumption may need to be reassessed.
Dave Fontenot argues that HF0's economic model is not designed from "how much we want," but rather from "what the LP needs," and then works backward to craft the optimal terms for founders.
Dave describes his design process: "I start by asking LPs: 'What is the most founder-friendly term for you?' Then I work backward from there." The result: 3% equity, 500K uncapped, converting at the next round's price.
Why 3% instead of 5% or 7%? Dave gives three reasons:
1. No valuation set: Many founders are serial entrepreneurs who have previously built unicorns (e.g., Alex Atala of OpenSea, Andrew D'Souza of ClearBank), and setting an early-stage valuation for them "feels wrong."
2. Sufficient cash: 500K is enough for them to hire third parties and purchase services during the residency to "buy back time." About half of the teams are already funded before entering HF0, while the other half take only HF0's money — 500K is enough to get started.
3. LP return model: Dave's fund structure is based on a "tail outcome of $10B+." He focuses on founders who are "playing the biggest game of their career" — "their last company might have been worth $2B, and now they are aiming for a company worth $100B."
Dave's self-promotional tone: He emphasizes that "3% is a f***ing better deal than 7%" and points out that "top founders don't even consider 7% terms." Readers should note that this is the perspective of a fund operator — HF0's appeal lies in its precise targeting of the most elite founders (who care about time more than money), rather than the absolute superiority of the terms themselves.
Dave Fontenot believes that understanding the essence of a "hacker" is key to building trust and driving innovation. He is still "converging" on a definition, but has one core judgment: a hacker is "an artist who doesn't care about the medium of expression."
"Hackers are artists." Dave emphasizes that although we use the word "engineer," we should not think it excludes creative expression. He believes that most people's understanding of hackers misses a key dimension: the desire to "be understood" – not just others understanding your work, but others understanding you as a person through your work.
Deductive Mechanism: This insight directly guides the operation of HF0. Dave observed in Hackathons that the "expo" segment is more important than the "build" segment itself – because "being seen" is a deep need of creators. In HF0, the Monday "demo dinner" satisfies this need: each team has 2 minutes to directly share their Stripe dashboard, with no slides, no showmanship – "Just show your real data."
Dave's Self-Assessment: He admits that this definition is still iterating, but the "artist" perspective is key to building trust when he runs Hackathons. He mentions that even those who consider themselves "non-technical" can be transformed into "hackers" in Hackathons – "The key is not your ability to write code, but the internal shift of believing 'I can do it.'"

1. “HF0 turns you into a 100x version of the ‘10x engineer.’” — Dave Fontenot
HF0 does not solve for “giving engineers more time,” but rather “getting the most exceptional engineers into a state of continuous flow” — those who were already 10x engineers can become 100x in HF0.
2. “The difference between a madman and a visionary is not ‘correctness,’ but ‘consistency.’” — Dave Fontenot
Dave arrived at this judgment from his experience of Vitalik Buterin sleeping over at his house: visionaries may not be entirely correct, but they start from a “felt sense,” and when they talk about the same thing at different times and from different angles, they are talking about the same thing — they have “seen” that future.
3. “HF0 does not provide advice; it provides mirrors.” — Dave Fontenot
Unlike accelerators such as YC, HF0’s core value is not “telling you what to do,” but “letting you see what you are doing” — especially when you are avoiding “the most important thing” by busying yourself with “the second most important thing.”
4. “The biggest distraction is not ‘social life’ or ‘parties,’ but ‘the second most important thing.’” — Dave Fontenot
Founders are often not lacking in effort — they simply spend time on the second most important thing, avoiding the “hardest yet most critical” problem. Through co-living, HF0 can identify this “avoidance pattern.”
5. “HF0’s economic model is ‘backward-designed, not forward-extracted.’” — Dave Fontenot
Dave first asked what LPs needed, then launched the 3% + $500K uncapped terms — rather than first thinking “how much can we take” and then forcing it onto founders.
6. “The 12-week residency’s ‘golden duration’ is not the result of rational optimization, but the product of real-world constraints.” — Dave Fontenot
It is not because 12 weeks is the most ideal, but because founders’ partners can tolerate at most 12 weeks. Yet once in flow, 12 weeks also happens to be long enough for the “breakdown-breakthrough” cycle to complete.
7. “What venture capital does today is equivalent to giving money to Olympic athletes and saying ‘see you at the Olympics.’” — Dave Fontenot
Core analogy: through its “whole-person care” model, HF0 attempts to transform early-stage investing from “capital + advice” into “comprehensive support” — including physical therapists, chefs, schedule optimization, etc.
8. “The desire to be seen is the deepest but most neglected need of hackers.” — Dave Fontenot
Hackers do not just want to “write code” — they want to be “understood” through their work. HF0’s weekly Demo Dinner essentially fulfills this need — two minutes, direct presentation of real data, no performance.
