In Q3 2024, the median pre-seed SAFE in the United States raised $275,000 at a $10 million post-money valuation cap, according to Carta's State of Pre-Seed report. That number tells you a lot. Pre-seed is not a small friends-and-family check. It is not a seed round either. It is its own stage, with its own rules, its own investors, and its own expectations. Founders who blur that line end up either leaving money on the table or approaching the wrong people entirely.
This guide lays out exactly what pre-seed funding is, who writes pre-seed checks today, what check sizes actually look like, how much equity you should expect to give up, and what investors want to see before they commit.
Pre-Seed vs. Seed: The Real Difference
The two stages share a name prefix, but they are meaningfully different in what investors expect from you.
Pre-seed is, by definition, any capital raised on convertible instruments before a company's first priced equity round. That is the definition Carta uses across its dataset of more than 100,000 convertible instruments raised by over 9,000 U.S. startups. No priced round. No institutional lead setting a per-share price. Usually no revenue. Sometimes no product.
Seed is different. Investors at the seed stage want traction. According to TechCrunch's 2024 guide to seed funding, investors like Maren Bannon of January Ventures are advising portfolio companies that $300,000 to $1 million in ARR is now considered strong positioning for a seed round. Three years ago, that number was enough to raise a Series A. The bar moved up. Pre-seed predates all of that.
At the seed stage, median deal sizes ran around $2 million in late 2023 and early 2024, with pre-money valuations around $10 million, according to PitchBook data cited by TechCrunch. Pre-seed rounds are smaller and happen earlier. The two stages are adjacent on a timeline but they are not interchangeable.
What Pre-Seed Check Sizes Actually Look Like
The range is wide. That is the honest answer. But the data narrows it down considerably.
Individual angel investors typically write checks in the $25,000 to $150,000 range per deal. Micro-VCs — funds generally under $50 million that focus exclusively on the earliest stages — often write $100,000 to $500,000 as their initial check. Accelerators occupy a category of their own.
Y Combinator, the most prominent accelerator globally, now invests $500,000 per company: $125,000 on a post-money SAFE in exchange for 7% equity, plus $375,000 on an uncapped SAFE with a Most Favored Nation provision. That structure is detailed directly on YC's standard deal page. No milestones. No waiting. The check goes out the day a company is accepted.
Across the broader market, Carta's data shows a clear skew toward smaller checks. In Q4 2024, 44% of all pre-priced rounds were under $250,000 — up from 30% in Q4 2023. That shift toward smaller rounds reflects a more cautious funding environment, not a shrinking stage. Total pre-seed capital in the U.S. in 2024 was approximately $4 billion across more than 25,000 convertible instruments, essentially flat from 2023.
So what is the realistic range? Most founders should plan for pre-seed rounds between $50,000 and $500,000 from angel-led syndicates or micro-VCs, with accelerator programs potentially adding $150,000 to $500,000 on top. Rounds above $1 million at the pre-seed stage exist — particularly in AI, where fledgling companies have raised outsized early checks — but they are the exception. Carta found that only 4% to 5% of pre-seed rounds exceeded $5 million in any given quarter during 2024.
Who Actually Writes Pre-Seed Checks
Three categories of investors dominate this stage. Understanding who they are and what they need is half the work of fundraising.
Angel Investors
Angels are high-net-worth individuals investing their own capital. They typically write checks between $10,000 and $200,000, though experienced angels and syndicates can aggregate significantly more. Angels move faster than institutions. They make decisions on conviction rather than committee consensus. They are also often the first phone calls a founder makes — frequently an operator or entrepreneur who has been through the experience themselves.
The best angels bring more than money. They bring industry access, warm introductions to future investors, and pattern recognition from their own building experience. A check from the right angel in your sector can serve as social proof that attracts the next investor.
Micro-VCs
Micro-VCs are institutional funds, typically managing between $10 million and $50 million, that write first checks into pre-seed and early seed companies. Unlike larger venture funds that need to deploy tens of millions per deal to move the needle on their returns, micro-VCs can write $100,000 to $500,000 checks and still generate meaningful fund returns if a company breaks out.
These funds have grown significantly in number over the past decade. They tend to have a defined thesis — a specific sector, geography, or founder profile they specialize in — which means founders need to do more homework before pitching. A micro-VC focused on climate infrastructure is not the right first call for a B2B SaaS company targeting the legal industry.
Accelerators
Accelerators offer a structured program in exchange for equity, plus a cash investment. YC's $500,000 check for 7% is the most well-known structure, but hundreds of accelerators operate globally across sectors ranging from biotech to defense to consumer hardware. Most offer smaller checks — often $50,000 to $150,000 — in exchange for 5% to 10% equity, though terms vary widely.
The value of an accelerator extends beyond capital. The YC network, for instance, effectively provides access to thousands of founders, operators, and investors. Demo Day exposure alone can compress months of fundraising into weeks. For founders without existing investor networks, an accelerator can be an efficient path to credibility and follow-on capital.
Dilution: How Much Equity Should You Expect to Give Up
The short answer: 10% to 20% at the pre-seed stage is normal. The data supports this range. According to pre-seed benchmarks published by WinSavvy, the median equity stake sold at the pre-seed stage is approximately 15%, with founders retaining 80% to 90% post-round. Anything above 25% in a single pre-seed round is a red flag — not just for your own ownership, but as a signal to future investors who will look at your cap table.
Here is the math that matters: if you raise $500,000 at a $5 million post-money valuation, you are selling 10%. If you raise the same $500,000 at a $2.5 million valuation, you are selling 20%. The valuation negotiation is really a dilution negotiation.
Most pre-seed rounds today use SAFEs (Simple Agreements for Future Equity) rather than priced equity. SAFEs are not shares — they convert into equity at a future priced round, typically at a discount or valuation cap. In Q3 2024, 89% of all pre-priced investments on Carta were structured as SAFEs, with 87% of those being post-money SAFEs. Post-money SAFEs create cleaner math. A $500,000 SAFE at a $10 million post-money cap equals exactly 5% dilution. No ambiguity.
One important consideration: YC's structure illustrates how accelerator dilution compounds. Their 7% fixed stake from the $125,000 SAFE plus the conversion of the $375,000 MFN SAFE means founders need to account for total YC ownership when modeling their cap table into the seed round.
What Founders Need Before Raising Pre-Seed
Pre-seed is not a blank-check stage. Investors are still evaluating risk. But what they look at is different from what seed investors want.
At the pre-seed stage, investors are primarily buying into three things: the founders, the problem, and the hypothesis. They are not buying proven product-market fit — that is a seed-stage conversation. Here is what you need in place before approaching pre-seed investors:
A clear and specific problem statement. Vague market observations do not close rounds. Investors want to see that you understand a specific pain point, that you have talked to potential customers, and that you can articulate why existing solutions fall short. User interviews, surveys, and letters of intent all serve as evidence.
A credible founding team. At this stage, team is often the primary diligence criterion. Investors want founders who have relevant domain expertise, a demonstrated ability to build things, or a track record of execution. If you are a first-time founder, the strength of your co-founder combination matters enormously.
A prototype or MVP, ideally. You do not need revenue. You do not need thousands of users. But a working prototype signals that you can build, not just pitch. Even a Figma mockup with a handful of early testers is better than a slide deck alone.
A realistic use-of-funds narrative. Investors want to know what specific milestones the pre-seed capital will unlock. Build to MVP? Hire your first engineer? Get to 100 paying customers? Map it out. The cleaner your plan, the more confidence investors have that their check will get you to a meaningful seed-stage milestone.
An incorporated entity. This sounds obvious, but many founders approach investors before they have incorporated. Most institutional pre-seed investors will not wire money to a sole proprietorship. A Delaware C-corp is the standard structure for venture-backed startups in the United States.
Real Pre-Seed Rounds: Named Examples
Data is useful. Real companies make it concrete.
CNaught, a science-backed carbon credit marketplace, raised a $2.25 million pre-seed round led by Greycroft in October 2023, with participation from Carthona Capital, Long Run Capital, and several angels, according to the company's Business Wire announcement. The founders had launched in April 2023, built an initial customer base including DuckDuckGo and Pure Insurance, and retired more than 10,000 tonnes of carbon credits — all before closing the round. That traction is what made a firm like Greycroft willing to write a lead check at the pre-seed stage.
Notion, now valued at over $10 billion, raised its first outside capital — a $2 million seed round from First Round Capital and SV Angel in early 2013, before the company had meaningful traction, as documented by First Round Capital. That was not technically labeled a pre-seed in today's terminology, but by the standards of the time it functioned identically: a small check into a team with an idea and a prototype, based almost entirely on the founders' vision and capability. It took five more years and a complete product rebuild before Notion found the traction that justified its next round.
Both stories illustrate the same point. Pre-seed capital buys time and proof points. It is not an endorsement of a finished product. It is a bet on the people and the problem.
Common Mistakes Founders Make at the Pre-Seed Stage
Three mistakes show up repeatedly.
Raising too much too early. The pressure to maximize your round size is real, but every dollar you raise costs equity. A $2 million pre-seed at a $5 million valuation leaves you with 60% of your company before you have hired anyone or built your product. Raise enough to reach your next milestone — typically 12 to 18 months of runway — and stop there.
Approaching the wrong investors. Sending your pitch to a growth equity fund or a Series B specialist is not just a waste of time. It damages your reputation among the investor community, which is smaller than most founders realize. Know your investor's stage focus before you reach out.
Neglecting the cap table. Every convertible note and SAFE you issue will convert into equity at your first priced round. Founders who issue equity casually to advisors, contractors, and early helpers before raising often arrive at their seed round with a messy cap table that raises red flags. Be deliberate about every line on your cap table from day one.
The Bottom Line on Pre-Seed
Pre-seed funding is the earliest institutional capital a startup raises. The typical round runs between $250,000 and $1.5 million. The median check lands around $275,000 on a $10 million valuation cap. Angels, micro-VCs, and accelerators are the primary sources. Founders typically give up 10% to 20% in equity. And the bar for raising is lower than seed — but it is not zero.
Show up with a compelling problem, a credible team, some form of validation, and a clear plan for how the capital gets you to your next milestone. That is what closes pre-seed rounds. Everything else is secondary.
