Pre-seed is a company's first outside money, usually raised on SAFEs from angels and small funds to prove the team can build something people want. Seed is the first round sized to reach product-market fit: larger, often led by a seed fund, at a higher valuation, backed by early traction. For angels, pre-seed means more risk at a lower price.
The labels are loose. One company's pre-seed is another's seed, and both have grown over the last decade. What separates them is less the name on the round than what the company has proven and what the money is meant to buy. This guide sets the two side by side and then looks at what each stage means for an angel deciding where to write checks.
The market data below comes from Carta, cited and dated.
Pre-seed vs seed, side by side
What the money is for.
Pre-seed: build the first version, test the problem with real users, and assemble the founding team.
Seed: find product-market fit, hire the first key people and reach the milestones a Series A investor will want to see.
What the company usually has to show.
Pre-seed: a team, an insight, and maybe a prototype, a waitlist or design partners.
Seed: a product in use, early revenue or engagement, and signs that customers come back.
How it's structured.
Pre-seed: almost always SAFEs or convertible notes, raised on a rolling basis rather than in one close.
Seed: still often SAFEs, but larger seed rounds are more often priced equity with a lead investor setting terms. Carta found that most $3 million to $4 million rounds in the first half of 2025 were raised on SAFEs or notes, and that the point where companies switch to priced equity seems to have moved from around $3 million to around $4 million.
Typical valuation.
Pre-seed: in Carta's Q2 2025 pre-seed report, the median valuation cap was $7.5 million for SAFE rounds under $250,000 and $10 million for SAFE rounds between $250,000 and $500,000.
Seed: the median pre-money valuation of new seed rounds on Carta was $16 million in Q1 2025, double the $8 million of mid-2019, according to Carta's State of Private Markets report.
Who invests.
Pre-seed: angels, friends and family, accelerators, pre-seed funds and scouts.
Seed: seed funds and multi-stage funds' seed programs, usually with angels filling out the round.
What comes next.
Pre-seed: a seed round, if the early evidence holds.
Seed: a Series A, or a bridge round if milestones take longer. Bridges have become common: about 46% of seed-stage deals on Carta in Q1 2025 were bridge rounds.
The guide to valuing a startup at the pre-seed stage explains how those caps get set in practice, and the piece on how much a typical angel invests covers check sizes inside these rounds.
What changes for the angel between pre-seed and seed?
Risk. At pre-seed you are mostly betting on the founders and the insight. Many companies never make it from pre-seed to seed, usually because they never find the right product.
Price and ownership. The same check buys more of the company at pre-seed. A $25,000 check on a $10 million post-money cap is 0.25%; at a $20 million seed post-money it is 0.125%. Both will be diluted by later rounds.
Information. Pre-seed diligence is thin by necessity: a few conversations, a prototype, references. At seed there is usage data, early revenue and often a lead investor's diligence to lean on.
Terms. Pre-seed angels usually accept the founder's SAFE as it is. In a priced seed round, a lead negotiates the terms and angels follow them, sometimes with less room to secure pro rata rights or information rights.
Access. Pre-seed rounds are often easier for angels to join, because founders are still looking for believers and checks are welcome. Hot seed rounds can be oversubscribed, with funds taking most of the allocation.
Which stage suits which angel?
As advice rather than a rule:
Pre-seed suits angels who can judge founders and markets early, ideally in a field they know, and who can be helpful when the company has almost no team. It also suits angels building a large portfolio of small checks, since prices are lower and the spread of outcomes is wide.
Seed suits angels who want more evidence before investing, who prefer a lead investor's diligence and terms, or who want to put in larger checks with a bit less risk per dollar.
Many angels do both: a small pre-seed check, then a follow-on at seed if the company earns it. Keeping reserves for that second check is one of the more useful habits in angel investing.
The lessons from successful pre-seed investments collect patterns from companies that went on to large outcomes.
Why the line keeps moving
Round sizes and valuations at both stages have drifted up for years. My own rounds, $1.4 million to $3 million, were all labeled seed rounds at the time. By Carta's 2025 data, raises of that size can be labeled either pre-seed or seed, and many would still be done on SAFEs.
A few practical consequences for founders and angels alike:
Read the milestones, not the label. A "seed" round with no product in market carries pre-seed risk at a seed price.
Watch the cap more than the round name. The valuation cap decides what an angel owns, whatever the round is called.
Expect more rounds in between. Pre-seed extensions and seed bridges are now ordinary. They are not a bad sign on their own, but ask what the extra money buys.
For founders, the guide to raising pre-seed funding in 2026 and how to raise a pre-seed round cover the first raise, and the seed fundraising checklist covers the next one. More on stages and terms is in the angel investing section.
Frequently Asked Questions
Q:How much is a typical pre-seed round?
There is no fixed size. Carta groups its pre-seed data into bands that start below $250,000, and it found that most rounds of $3 million to $4 million in early 2025 were still raised on SAFEs or notes. In practice pre-seed runs from a small angel round to a few million dollars.
Q:Is pre-seed always raised on SAFEs?
Not always, but usually. SAFEs and convertible notes are quick and cheap to sign, which suits small rounds raised in pieces. Priced equity becomes more common as rounds reach the multi-million dollar range.
Q:How long is the gap between pre-seed and seed?
It varies widely, often a year or more. The pre-seed money needs to last long enough to show the evidence a seed investor wants, so it is sensible to plan for 18 months of runway or more.
Q:Can a company skip pre-seed and raise a seed round first?
Yes. Founders with a track record, a strong network or early revenue often raise a seed round as their first outside money. Others skip outside money until seed by bootstrapping the first version.
Q:Should a first-time angel start with pre-seed or seed?
Many start at seed, where there is more information and often a lead investor to learn from, then move earlier as their judgement improves. Others start at pre-seed in a field they know well. Either way, small checks across many companies matter more than the stage.
