Hustle Fund: $100M+ Pre-Seed VC That Writes $100K Checks and Believes in 'Fast and Frugal' Founders

Most VCs spend their days filtering decks that arrived via warm intro from a warm intro. Hustle Fund does not play that game. The San Carlos firm, founded in 2018 by Eric Bahn, Shiyan Koh, and Elizabeth Yin, all former founders themselves, built Hustle Fund around a contrarian bet: the best companies get built by people who know how to do more with less.

That philosophy is not marketing copy. Hustle Fund literally coined the term 'fast and frugal' to describe the founder archetype they seek. These are operators who launch before they have product-market fit, who talk to customers on day one, who ship weekly and measure progress week-over-week. The fund sees capital efficiency as a signal, not a constraint. If you can build something real with $50K in the bank, imagine what you could do with a real check.

Hustle Fund writes $100K-$150K checks at pre-seed, making them one of the earliest cheques in the market. When those companies graduate to seed, Hustle often follows with $500K-$1M. They review over 1,000 deals per month and pride themselves on moving in days, not months. No committee. No waiting for a lead. If a GP is convinced, the wire goes out.

The firm's name is not subtle, and that is the point. 'Hustle' is a genotype, not a work ethic. It shows up in how a founder writes their first line of code, how they handle a customer complaint at 11pm, how they think about competition. Hustle Fund has backed founders others dismissed because the founder's hustle was visible in ways that a pitch deck cannot fully capture.

The fund also runs Angel Squad, a community of over 2,000 angel investors who co-invest alongside Hustle Fund in exchange for deal access and education. It is a flywheel: portfolio companies get more capital from aligned angels, angels get access to Hustle's earliest deal flow, and Hustle Fund builds a reputation as the firm that opens doors, not just writes cheques.

Hustle Fund's thesis starts with a founder, not a market. The logic: at pre-seed, there is no data, no traction, no benchmark. What exists is a person and their ability to ship. The fund explicitly states it does not start with a founder's background or pedigree. It starts with hustle.

Their blog frames it directly: 'How do you know what to invest in at pre-seed? A lot of people assume VCs start with the founder's background. Where they worked.' Hustle Fund starts elsewhere. They look for demonstrated execution: a working prototype, real user feedback, a clear sense of what problem is being solved and why this person will solve it better than anyone else.

The 'fast and frugal' archetype means Hustle Fund gravitates toward capital-efficient businesses by design, not by circumstance. Developer tools and B2B SaaS are natural fits because they can reach product-market fit without massive sales cycles or infrastructure spend. The fund also has a growing interest in AI agents, where the combination of a technical founder and a real workflow problem tends to produce durable businesses.

What Hustle Fund explicitly avoids: consumer apps, hardware, anything requiring 18 months of R&D before a prototype exists. The firm's operational background means they are impatient with companies that need runway just to test hypotheses. They want businesses where the next milestone is weeks away, not quarters.

Hustle Fund has remained active through 2024 and into 2025, deploying capital across pre-seed and seed rounds. The firm continues to find its best deal flow through direct inbound, portfolio referrals, and its Angel Squad community of over 2,000 individual angels who see deals earlier and often co-invest.

The fund's deal velocity remains high relative to fund size, a function of writing smaller cheques at the earliest stage. Each GP is expected to develop independent conviction without committee process. When a GP says yes, the investment can close within days.

Hustle Fund has also been active in follow-on rounds for strong performers, moving from pre-seed to seed alongside companies that demonstrate week-over-week progress. The firm has been particularly active in AI infrastructure and developer tooling, reflecting the backgrounds of its GP team.

On the operational side, the fund expanded Redwood School, its sales training program for portfolio companies, and Camp Hustle Asia, a founder gathering in Bali that doubles as a sourcing event. These programs reinforce the 'founder-first' brand and generate deal flow that looks like friendship, not pitching.

Webflow is the crown jewel. Hustle Fund was among the earliest investors in the no-code website builder, which reached a $4B+ valuation and remains one of the most consequential companies to emerge from the SF Bay Area in the past decade. The Webflow founders, Viktor and Sasso, represent the Hustle Fund archetype: technical depth, relentless iteration, and a product that spread by word-of-mouth before any real marketing budget existed.

NerdWallet went public, making it a defining exit for the fund and proof that consumer financial comparison can be built into a serious business. The Hustle Fund bet on NerdWallet's founder Matt Clark early, when the company was still a one-person operation running experiments out of a spare bedroom.

Cal.com is the open-source Calendly alternative that has built significant traction in the developer community. The company raised a $7.4M seed round and has become a go-to scheduling infrastructure layer for products that need calendar integrations. Cal.com represents Hustle Fund's thesis that infrastructure with a great developer experience can commoditize established categories.

Boom Supersonic is the outlier. A hardware company in a fund that avoids hardware? Boom is the exception Hustle Fund makes for founders with a deep technical pedigree and a market timing argument. The company's X-1 demonstrator aircraft broke the sound barrier in record time, and its Overture supersonic commercial aircraft has airline commitments from United and Japan Airlines.

Form builds no-code business logic tools, letting operations teams build workflows without engineers. The company targets the long tail of enterprise software that traditional SaaS vendors ignore, and has found strong product-market fit among mid-market companies frustrated by rigid tooling.

Loops is a cold email platform that competes in a crowded space against established players like Apollo and Hunter. The differentiation is AI-native outreach workflows that adapt in real-time based on engagement signals. Loops has grown largely through organic developer community adoption, a pattern Hustle Fund loves.

Metal builds data infrastructure for AI applications, helping companies manage the pipelines that feed large language models. As enterprise AI adoption accelerates, Metal sits at a critical junction of data engineering and model deployment that VCs find increasingly attractive.

Other notable names in the portfolio include companies across productivity software, fintech infrastructure, and developer observability, though the fund is deliberate about not publishing a full list, preferring founders to control their own narratives.

Hustle Fund's portfolio approach is to take large ownership stakes at the earliest stages and let compounding do the work. With pre-seed checks in the $100K-$150K range against $1M-$3M seed valuations, even a modest fund retorno requires winners to be significant. The fund's winners so far suggest the strategy is working.

The Hustle Fund team is explicit: they look for the 'hustle genotype.' This is not about working 80-hour weeks or sleeping at the office. It is about a specific quality of decision-making under uncertainty. Hustle genotype founders make decisions fast, update beliefs fast, and ship things that can be tested by real users within days, not months.

Technical founders get priority. Hustle Fund's three GPs are all technical or product people by background, and the fund has a clear bias toward founders who can build what they sell. Non-technical founders are not rejected outright, but they face a higher bar to demonstrate why their co-founder or early hire completes the team.

The fund looks for businesses where the next meaningful milestone is achievable within four to six weeks. This could be a working prototype, first paying customers, or a measurable signal that a specific audience segment is engaged. The point is not the milestone itself. It is evidence that the founder knows what to optimize for and can execute against a tight timeline.

Capital efficiency is a filter, not a goal. Hustle Fund does not expect founders to be broke, but they do expect them to understand the relationship between capital and progress. A founder who burns $200K in four months with nothing to show for it is a different signal than one who spends $50K and has three enterprise pilots running. Hustle Fund can work with either, as long as the relationship between spend and progress is honest.

Honesty is underrated in Hustle Fund's process. The GPs have seen thousands of pitches and can spot performance from a mile away. The founders who get funded are the ones who can say 'I do not know' and then figure it out in real time.

The best path to Hustle Fund is a warm introduction from a portfolio founder, an Angel Squad member, or a founder whose company resembles a Hustle Fund investment thesis. The firm sees roughly 1,000 deals per month, and referrals move faster than cold inbound.

Cold submissions go through the form at hustlef.vc. The GPs read every submission, though response times vary. A cold submission that clearly signals hustle genotype, shows evidence of shipping, and names a specific problem with a specific customer in mind will outperform the generic 'we are building the future of X' deck every time.

The Hustle Fund FAQ on their site is unusually transparent for a VC firm. They answer the questions founders actually ask: what stage, what check sizes, what sectors, do they lead or follow. Reading it before applying will save everyone time.

For founders who do not fit Hustle Fund's thesis, the Angel Squad is an alternative path. Angel Squad members can make independent investment decisions, and many have written $1K-$25K cheques into pre-seed companies that are too early even for Hustle Fund. It is a way to build a relationship with the Hustle Fund ecosystem while your company matures.

Timing matters. Hustle Fund moves in days but operates on a deal-by-deal timeline, not a fund deployment calendar. There is no 'right season' to pitch. What matters is showing progress since your last milestone. If you met the team three months ago and have nothing new to show, do not re-pitch. If you have real evidence of growth or a meaningful product update, the re-pitch is worth it.
