Dilution Isn't the Enemy

Part of our ongoing Tuesday series on the mechanics of ownership in angel investing — dilution, follow-ons, and the terms that decide what your stake is actually worth.

Want to put your learning into action?

We share one vetted startup deal every week. Always free to lurk and learn.

💎 Nearly every new angel I've talked to winces at the word dilution. A startup they invested in raised more money and their ownership stake decreased. They think they got robbed.

I hear dilution, and get excited. By the end of this post, you will too.

Dilution is good news

Here's what actually happens.

Your portco (angel slang for portfolio company) raises a new round. They create new shares to sell to the new investor. Your share count doesn't change. Your percentage does. It gets smaller.

They create new shares to sell to the new investor.
Your share count doesn't change but since the number of shares got bigger your percentage got smaller.

Panic? Nope! Between pre-seed and Series A, your ownership often gets cut in half. Your investment value typically triples. A smaller slice of a bigger pie is worth more than the bigger slice was yesterday.

Someone with more information than you just decided this company is worth more than when you got in.

🌶️ Fun Fact: You only get diluted when the next round is a priced equity round. If you invested on a SAFE and the next round is a SAFE (very common these days) the percent ownership you'll get when the SAFE converts to equity remains untouched.

The doubling-down myth

The second most common reaction after hear the word dilution is: "Should I follow on to protect my ownership percentage?"

Almost always: No.

That's a VC rule for a VC game. VCs raise funds with follow-on reserves baked in because they promised their LPs they'd protect ownership. You didn't promise anyone anything.

Abe Othman, head of data research at AngelList, studied every early-stage round over the past decade. He coined a term for what happens when angels double down on an existing investment instead of writing a new check:

Infinite Regret. ‼️ (Honestly this term makes data science sound way more dramatic than it is.)

Here's what it means:

Invest that same dollar into a new company – that next one could be your breakout star.
Doubling down on an existing (and still unproven) investment doesn't help with portfolio diversification.
It just boosts the cost basis on your original bet.

Investing at a $5M valuation and then doubling your investment at a $50M valuation just turned your cost basis from $5M to $27.5M. To 100x your investment you need a $2.7B exit not a $500M exit.

Ooofff.

You're not being disloyal. And as an angel you are not "signaling" the market. You're being smart. The data says so.

But also, it's your money and your rules.

I have doubled down on a few bets. Momentum and seeing the founder in action for longer builds emotion. We're human and Angel is a reflection of our values and vision as much as it is an asset class. Do you!

The cram down trap

Here's where to tred cautiously....

A "cram down" or "down round" is when a struggling company raises at a lower valuation, and the new terms punish anyone who doesn't re-up their investment aka: anyone who doesn't take their pro-rata share.

If you don't invest more money your preferred shares convert to common shares. Sometimes you even get fewer shares.

It sounds unfair, but the new investors with new capital coming in to potentially save a struggling startup get to make the rules. The investment is definitely going to zero without them.

You can identify cases like this when you hear things like: "if there's ever an exit, you get 2x your money back first."

Shiny. Sounds like a big benefit. Be aware. It's a wolf in sheep's clothing.

There is nothing you can do. Take the loss. Protect your dry powder. Put that dollar into your next new shot on goal.

📖 I lived this one. A few summers ago, a reputable fund pitched their angel network on a later-stage round into a beloved women's health brand. The 2x liquidation preference was the headline. The investment ran through an SPV, so the actual terms were hidden.

Neither the fund nor the founder addressed what was really going on. I asked for the underlying docs. Someone who wasn't supposed to share them did. The angels weren't getting a deal. The company was distressed and the "reputable fund" was getting unsuspecting Angels to cover their pro-rata so they (the fund) could preserve their shares but didn't have to throw good money after bad.

PS: This experience is the reason every Play Money SPV shares the underlying investment terms upfront. No hiding.

TLDR: Dilution isn't the enemy. It usually means your bet is working. Protect your dry powder and keep swinging.

Frequently asked questions

Dilution happens when a startup you've invested in raises a new round of funding by creating and selling new shares. Your original share count stays the same, but because the total number of shares outstanding grows, your percentage ownership shrinks. This isn't a sign something went wrong — it's usually a sign a new investor decided the company is worth more than it was when you got in. Dilution is expected and, in most cases, a good indicator that your investment is appreciating rather than a warning sign that you were shortchanged.

Usually not. Protecting ownership percentage through follow-on checks is a VC playbook, built around promises VCs make to their own fund's limited partners. As an individual angel, you don't have that obligation. AngelList's head of data research, Abe Othman, found that doubling down on an existing bet instead of writing a new check into a new company tends to produce worse outcomes — a pattern he calls Infinite Regret. Putting fresh capital into a new, unproven company usually helps your portfolio more than adding to a position you already hold, since it raises your average cost basis without improving diversification.

Every follow-on investment raises your blended cost basis toward the valuation of the round you're investing at. For example, investing at a $5M valuation and then doubling your position at a $50M valuation pushes your effective cost basis from $5M up to roughly $27.5M. That means you now need a much larger exit — in this example, around $2.7B instead of $500M — to hit the same 100x return multiple you were tracking toward on your original check alone.

A cram down (also called a down round) happens when a struggling company raises new money at a lower valuation than its prior round, on terms that penalize existing investors who don't participate. If you don't invest more to maintain your pro-rata share, your preferred shares can convert to common shares, and you may end up with fewer shares than before. It sounds harsh, but the new investors bringing in capital to keep a distressed company alive are the ones setting the terms — without them, the investment is often headed to zero anyway.

Watch for language like "if there's ever an exit, you get 2x your money back first" — a liquidation preference framed as a benefit can be a signal that the round is really a rescue financing dressed up as an opportunity. Ask for the underlying deal terms rather than taking a fund's summary at face value, especially when the investment runs through an SPV that can obscure what's actually happening. If a deal looks like new investors are being asked to cover existing investors' losses so an earlier backer can preserve its position, treat it as a red flag.
