Most angels put $15,000 to $37,500 into a single startup: that was the middle half of checks in the largest US survey of angels, which found a median of $25,000. Angel groups commonly invest a few hundred thousand dollars per deal, and rounds built mostly from angels usually total a few hundred thousand to a few million dollars.
This is the founder's version of the question: how much to expect from each angel, and how many angels a round takes. If you are on the other side and want to know how much money it takes to start investing, the guide to how much money you need to start angel investing covers that.
I've seen both sides. As a founder I raised three seed rounds: $1.4 million for MovieLaLa in 2013, with Marc Benioff among the investors, $1.5 million for MojiLaLa in 2016 and $3 million for Leo AR in 2018. Along the way I met 500+ investors and raised from 100+ of them. As an angel I've made 234 investments, and Lenny's Newsletter ranked me the #1 most active angel investor in 2024.
How much does a typical angel invest in one startup?
The best public data on individual check sizes is The American Angel, a 2017 report commissioned by the Angel Capital Association and led by researchers at Wharton. It surveyed 1,659 accredited US angels and found:
A median check of $25,000 and an average of about $35,000. The middle half of angels invested between $15,000 and $37,500 per company.
A wide range. The largest checks in the sample reached $750,000.
Bigger checks from experienced angels. Angels who had been investing longest averaged $42,000 per startup; newer angels averaged $25,000. Angels with entrepreneurial experience wrote larger average checks than those without.
Portfolios, not single bets. The average angel held about 11 companies (median 7).
The survey is several years old, and valuations have risen since, so treat these as a floor for today's market rather than a precise current figure. The shape still holds: most angels write many small checks rather than a few large ones, because a few winners have to pay for the companies that fail. The explainer on how angel investors make money shows why that math pushes angels toward small, spread-out checks.
At the ends of the range, some checks are only a few thousand dollars, through syndicates and online platforms that pool small amounts. At the other end, a few very active angels and former founders write checks in the hundreds of thousands and sometimes lead rounds.
How big are angel rounds?
Round size depends on stage, and the data comes from different sources:
Angel groups. A 2018 pilot report from the Angel Capital Association, covering 26 angel groups (2017 data), found a median round size of $1 million, a median of about $202,000 invested by the group in each round, and a median of 10 group members per deal.
Pre-seed. Carta tracks pre-seed as money raised on SAFEs and convertible notes before any priced round. Carta's Q2 2025 pre-seed report found a median valuation cap of $7.5 million for SAFE rounds under $250,000 and $10 million for SAFE rounds of $250,000 to $500,000. It also found that most $3 million to $4 million rounds in the first half of 2025 were raised on SAFEs or notes.
Seed. In Q1 2025, startups on Carta closed 401 new seed rounds that raised $1.2 billion in total, about $3 million per round on average, at a median pre-money valuation of $16 million, according to Carta's State of Private Markets report. Seed rounds of that size usually combine angels with seed funds.
My three seed rounds, from $1.4 million to $3 million, sit inside that seed range, though they were raised years before these datasets. Stage by stage, pre-seed vs seed rounds compares the two.
How many angels will your round need?
The arithmetic is simple and sobering. At a $25,000 median check, a $500,000 angel round means about 20 investors. A $1 million round could mean 40. Each one is a meeting, a follow-up, a signature and a line on your cap table.
Ways founders keep that manageable:
Find a lead angel first. One respected angel committing a larger check makes the rest of the round move faster.
Set a minimum check. Many founders set one to keep the cap table tidy, while making exceptions for angels who bring specific help.
Use a pooling vehicle. Roll-up vehicles and SPVs let many small checks appear as a single line on the cap table.
Mix in institutional money. A seed fund can take a large share of the round so angels fill the rest.
Run a tight process. The guide to raising pre-seed funding in 2026 and the seed fundraising checklist cover the timeline and documents.
Mind the securities rules too. Most US angel rounds rely on Regulation D, which is built around accredited investors: broadly, people with $200,000 of income ($300,000 with a spouse or partner) in each of the last two years, or $1 million of net worth excluding their home, plus holders of certain financial licences. If friends and family who don't qualify want in, talk to a lawyer before taking the money.
What decides how much an individual angel puts in?
Founders often read a small check as low conviction. Usually it reflects the angel's own rules:
Portfolio strategy. Angels who aim for 20 or more companies keep each check small. The guide to angel portfolio strategy explains why.
Reserves. Many angels hold back money for follow-on investments, so the first check is smaller than what they might invest over the company's life.
Stage and price. The same angel may write a smaller check at a higher valuation.
Relevance. Angels tend to write larger checks where they know the market or can help directly.
Round dynamics. In an oversubscribed round, angels often get cut back to whatever allocation remains.
You can ask an angel what their typical check is. It is a normal question, and the answer tells you how many more conversations you need.

Frequently Asked Questions
Q:What is the smallest check an angel investor writes?
There is no fixed minimum. Some platforms and syndicates accept a few thousand dollars, while many individual angels start around $10,000 to $25,000. Founders often set their own minimum to keep the cap table manageable.
Q:How much equity do angels get for their investment?
It depends on the valuation, not the check alone: a $25,000 check at a $10 million post-money valuation buys 0.25%. Across a whole seed round, founders typically sell around a fifth of the company; Carta reported median seed dilution of 18.8% in Q1 2025.
Q:Do angel investors lead rounds?
Some do, especially experienced angels and angel groups, which may set terms and organize the paperwork. More often, angels follow a lead investor's terms. A lead angel is valuable because others commit faster once someone has.
Q:Can non-accredited investors invest in my startup?
In limited ways. Some exemptions allow a small number of sophisticated non-accredited investors, and Regulation Crowdfunding lets companies raise from the public through registered platforms, with per-investor limits. Get legal advice before accepting money from anyone who isn't accredited.
Q:Is it better to raise from many small angels or a few large ones?
Fewer, larger checks save time and keep the cap table simpler. Many small checks can bring a broader network of advisers and customers. Most rounds end up as a mix, often with a pooling vehicle for the smallest checks.
