The published numbers on angel investing look good. The Kauffman Foundation funded the most cited academic study on this topic: the Angel Investor Performance Project. It tracked 3,097 investments and found a 2.6x cash return and roughly 27% gross IRR. A 2016 follow-up by the Angel Resource Institute puts the figure at 2.5x and 22% gross IRR. On paper, those angel investing returns average out well against early-stage venture capital funds.
So why do so many individual angels end up disappointed?
Angel investing does not produce bad returns for everyone. The issue is who those studies actually measured: group-based angels who co-invest, spread bets across many deals, and run rigorous due diligence on each one. That investor is not who most angels actually are — and for many, it is not who they ever become.
This piece works through the math to show exactly where the gap lives.
What the data actually measures
The original Angel Investor Performance Project studied 538 group-affiliated angels across 1,137 realized exits. The 2016 Angel Resource Institute follow-up covered 91% of exits between 2010 and 2016.
Both studies draw from organized angel groups. These are investors who meet regularly, co-evaluate deals, and share information on early stage companies. They are not a random sample of accredited investors writing checks to founders they met at a conference.
This distinction changes what the numbers mean. Group-affiliated angels see better deal flow. They run shared due diligence, which closes information gaps. The group structure keeps deal volume steady over time.
That makes it much easier to build a broad portfolio. And most group-affiliated angels understand the power-law math behind early stage investing before they commit their initial investment.
The 2017 American Angel survey measured the actual portfolios of US angels. It covered the broader accredited investor population — not just organized angel groups. The median active portfolio held seven investments. The mean was 11.4.
Seven positions is not a broad portfolio in early stage startups. It is a concentrated bet that the outcome curve will, by chance, include one significant winner. That is a very different proposition from what the academic studies measured.
The deal-level math
Most new angels miss how skewed startup outcomes are at the deal level.
The 2016 Angel Resource Institute study found that 70% of individual exits returned less than the capital invested. The original 2007 data put the figure at 52%. Multiple independent sources point in the same direction: a majority of individual angel investments lose money.
This is not a failure of judgment. It is the arithmetic of early stage companies. Most do not survive to a meaningful exit. Of those that do, most return modest multiples.
A small fraction produce large outcomes. The 2016 ARI study found that 10% of exits generated 85% of all cash returned.
Seth Levine's analysis of public financing data tells the same story. Roughly 65% of VC financings fail to return the initial capital. Only about 10% reach 5x, and just 4% reach 10x or above.
A portfolio's return depends almost entirely on whether it holds one of the rare deals that drive most of the gains. A portfolio of seven positions has limited exposure to that outcome. The math does not forgive too-small portfolios.
The portfolio size problem
Kauffman Foundation and Angel Capital Association data show that angels who build 12 or more investments over five or more years have roughly a 75% chance of achieving a 2.6x multiple. The volume, time, and consistency required to reach that outcome are all significant.
ACA-cited research comparing returns by portfolio size makes the point directly. Portfolios of 15 or more portfolio companies returned about 2.6x over ten years. Portfolios of fewer than 10 companies returned about 0.8x — a net loss. That is a large gap between what is possible and what the median angel actually builds.
Most frameworks cite 10 investments as the bare minimum for early stage investing. The 20 to 25 range is where a portfolio starts to reflect the real odds of startup outcomes rather than pure chance.
A 2020 AngelList study by Koh and Othman tracked thousands of LPs and found that returns rose steadily the more deals each investor held.
The pattern is consistent: spreading bets is the mechanism that makes angel investing work in aggregate. Without it, the investor is not accessing an asset class. They are making a series of individual bets on a small number of startup companies.
The median angel, holding seven positions, is making individual bets.
Three structural problems
Portfolio size is one part of the problem. Three structural weaknesses compound it.
Deal sourcing
Large VC financing datasets consistently show that a tiny fraction of deals — roughly the top 0.5% of all venture-backed companies — produce more than half of all industry returns. This includes many of the biggest companies to come out of Silicon Valley. Returns in venture capital do not come from making more bets. They come from getting into the right companies early.
Top venture capital firms spend years building the relationships and reputation that get them into those deals before they become obvious. Most individual angels do not have that access, especially early in their investing career.
Pro-rata rights and dilution
When a startup raises a new round, early investors get diluted. Pro-rata rights let them maintain their equity stake — but only if they invest more capital. Venture capital firms typically negotiate strong pro-rata protections and hold reserves to use them.
Most individual angels either lack pro-rata rights or cannot afford to exercise them. A 2% equity stake at the seed stage might shrink to 1.2% by Series B. At exit, that lost ownership is real money.
Due diligence time and legal costs
The Angel Capital Association recommends at least 20 hours of due diligence per deal. Investments with that level of research were about five times more likely to produce positive returns.
Hustle Fund estimates that managing a 10 to 15 position angel portfolio takes 30 to 45 full work-weeks over a decade. Legal costs add to the overhead. Simple SAFE reviews typically run $2,500 to $5,000. Equity rounds cost noticeably more. For a seven-position portfolio, the total time and legal expense is high relative to the capital at work.
Angel investing vs venture capital fund: what the comparison shows
When comparing angel investing vs venture capital fund structures, the data is more nuanced than either side usually presents.
The best academic data shows organized angels earning 2.5x gross returns and 22% to 27% gross IRR over 3.5 to 4.5 years on average. These are strong numbers. The Angel Resource Institute notes they compare well to early-stage VC fund gross returns in similar periods.
But gross IRR is not net IRR. Net returns to LPs in VC funds run lower after management fees and carried interest. Cambridge Associates' US Venture Capital Index shows a 10-year pooled net IRR of about 13% as of mid-2025. Carta's benchmark data for 2017 vintage funds shows a median net IRR of about 11.5%. The spread across venture capital firms is wide: the top 10% hit roughly 28%, while the bottom 25% sit near 5%.
The more meaningful comparison is between the median individual angel and the median VC fund.
The median VC fund delivers low-to-mid teens net IRR. That reflects a broad portfolio of portfolio companies, professional manager selection, actively managed pro-rata positions, and no personal time requirement from the LP.
The median individual angel portfolio returns about 0.8x over ten years — a nominal loss. That figure is an industry estimate, not a peer-reviewed result. But it lines up with what the deal-level data and portfolio-size research would predict for a seven-position portfolio.
A well-organized angel with 15 or more positions, strong due diligence, and pro-rata rights can match average VC fund returns on a gross basis. That investor exists. But most angels do not start there — and many never get there.
The LP structure as an alternative
For accredited investors who want long term venture exposure, the LP model in a venture fund solves several problems at once.
An LP in a venture fund holds exposure to 20 to 40 portfolio companies through a single commitment. Professional venture capital firms handle deal sourcing, due diligence, and active governance. The fund manages pro-rata rights and holds capital for follow-on investments. The investor commits once and does not carry ongoing diligence or legal costs.
Research by Gredil, Liu, and Sensoy shows that investing in too few funds can cost investors up to five percentage points in risk-adjusted returns.
Five funds per year is enough to spread most fund-level risk. Fund-of-funds structures can add real value through broad exposure — even when the average underlying fund performs only around the industry mean.
Vanguard's 2023 analysis found that adding a private equity sleeve to a traditional portfolio raised the Sharpe ratio by about 24%. It also raised the odds of achieving 6% or higher annual returns over ten years from 48% to 65%. The gain is not higher average returns. It is the risk-smoothing effect of spreading capital across many managers and companies.
Only 4.3% of accredited investors in the US currently own any private market securities, according to SEC data. Most have not built broad angel portfolios or taken LP positions in venture funds — even though they are eligible for both. For most accredited investors, the fund-level path offers a more direct route to meaningful venture exposure.
The honest summary
Angel investing works. The 2.5x multiples and 22% gross IRR from two decades of academic research are real numbers, drawn from real exits.
But reaching those figures requires specific conditions: a broad portfolio, high due diligence volume, group infrastructure, and pro-rata access. Most angels who write a few checks have not built any of that.
The gap comes from concentrated portfolios, weaker deal access, dilution, and time costs that the headline studies never captured.
The real question is not whether early stage investing can produce strong returns. It can. The question is whether the conditions required — 15 to 25 positions, 20 to 40 hours of due diligence per deal, follow-on capital reserves, and real deal access — are conditions a given investor can actually meet.
For most, the more direct path to venture exposure is as an LP in a professionally managed fund structure. Not because individual angels fail. Most investors simply cannot meet the conditions that make angel investing work at scale.
Frequently asked questions
Why do angel investors lose money?
Most angel investors lose money on individual deals. Multiple academic studies find that 52% to 70% of early stage startups fail to return the capital invested. At the portfolio level, the main cause is too few bets. The median US angel holds only seven positions — not nearly enough to reliably capture the rare companies that drive most venture returns. Without a large enough portfolio, the odds of holding a big winner are low.
What is the average return on angel investing?
The best available data on angel investing returns average comes from two major academic studies. The 2007 AIPP found a 2.6x gross return and roughly 27% gross IRR over an average 3.5-year holding period. The 2016 Angel Resource Institute update puts the figure at 2.5x and 22% gross IRR over 4.5 years.
Both studies draw from organized angel groups with broad portfolios. The median individual angel, with fewer than 10 positions, is likely to see noticeably lower returns.
How does angel investing compare to investing in a venture capital fund?
Angel investing vs venture capital fund investing comes down to structure and how broadly risk is spread. Well-organized angels with 15 or more portfolio companies can match early-stage VC fund gross returns. After fees, the median VC fund delivers roughly 11 to 13% net IRR. The LP also avoids due diligence costs, legal overhead, and dilution risk.
The median individual angel portfolio returns about 0.8x over ten years — a nominal loss. The median VC fund returns low-to-mid teens net IRR over the same period.
How many investments does an angel need for a broad portfolio?
Research from the Kauffman Foundation and Angel Capital Association suggests a minimum of 12 investments over five or more years for a 75% chance of achieving a 2.6x multiple. Most practitioner frameworks cite 20 to 25 positions as the range where a portfolio starts to behave by the numbers rather than by chance. ACA data shows portfolios of fewer than 10 early stage companies returning about 0.8x on average.
Can accredited investors participate in venture capital as LPs?
Yes. Individual accredited investors are legally eligible to invest as LPs in venture capital funds. Most traditional VC funds set minimums that exclude individual investors in practice, but a growing number of platforms targets the accredited investor market at lower entry points. SEC survey data shows only 4.3% of accredited individuals currently own any private market securities, suggesting LP access to venture capital remains significantly under-used by eligible investors.
