Understanding equity dilution for early-stage startups

Early-stage founders often need to make time-sensitive fundraising decisions to propel their companies forward, yet they’ll freely admit that they rarely understand the long-term implications of their decisions.

Whether you’re a founder raising capital for the first time or an investor looking to protect your stake, understanding how equity dilution — or dilution of ownership — works is critical for making well-informed financial decisions.

What is equity dilution?

Equity dilution is the reduction in an owner’s percentage stake when a company issues additional shares to investors or employees.

It usually takes place during:

• Fundraising rounds
• Employee stock option grants
• Conversion of convertible debt

Although it helps bring fresh resources, it can dilute individual control and overall financial equity.

What is capital dilution?

Used interchangeably with equity dilution, capital dilution reduces the percentage of ownership, voting power and claim on proceeds. However, if the new capital raised is used effectively to grow the company, the overall value of each shareholder’s stake may increase despite the decreased percentage.

Benefits and risks of equity dilution

While equity dilution is often a necessary component of startup growth, it’s crucial to understand the potential impacts. Many founders ask, “Is equity dilution bad?” — and the answer isn’t a simple yes or no. It depends on how well you manage the process. Let’s explore the potential benefits and key risks.

Potential benefits of strategic dilution 

• Access to growth capital: Dilution allows startups to raise necessary funds for expansion, product development and market penetration.
• Increased company valuation: If the capital is used effectively, it can lead to significant growth, potentially increasing the overall value of the company.
• Broader network and expertise: New investors often bring valuable connections and industry expertise along with their capital. The impact of increased networking from new investors can be a major step toward the success of your startup.

Key risks of equity dilution

• Loss of control: For founders, dilution of ownership can mean a decrease in their voting power and influence over key company decisions. This can be particularly concerning if new investors have different visions for the company’s future.
• Reduced profit share: Dilution directly impacts your share of future profits and any proceeds from a potential acquisition or IPO. A smaller ownership stake means a smaller piece of the pie. 
• Decreased founder motivation: For some founders, seeing their ownership percentage shrink can be demotivating, especially if they feel their contribution and vision are being undervalued.
• Difficulty attracting future investments: Excessive dilution in early rounds can make it harder to attract investors in later stages. Investors want to see that founders and early investors retain a significant stake, demonstrating their commitment and belief in the company’s potential.

When managed strategically, dilution can provide the resources needed to fuel growth and ultimately increase the overall value of your company, even if your ownership percentage is smaller.

Equity dilution example: Simple cap table math

Let’s illustrate share dilution with a simple example. Imagine you start a company, and you own 100 percent of 1 million shares.

Initial state:

• Your ownership: 100 percent (1 million shares)
• Company valuation: $1 million
• Your stake value: $1 million

After raising $500,000 at a $2 million pre-money valuation:

• New shares issued: 250,000
• Total shares: 1.25 million
• Your ownership: 80 percent (1 million shares)
• Company valuation: $2.5 million
• Your share value: $2 million

While your percentage ownership decreased from 100 percent to 80 percent, the value of your stake increased from $1 million to $2 million. This demonstrates how dilution, when coupled with effective growth strategies, can increase overall shareholder value despite decreased ownership percentage.

Tips for managing equity dilution

For many entrepreneurs, a successful fundraising round is a time to celebrate. The influx of money provides room to grow. But it can come at the expense of control and room to maneuver later. Many seasoned founders will tell you to only take as much capital as you think you really need.

Figuring out how much that is, of course, is the hard part. If you raise too much, you could give away an unduly large portion of your company. If you raise too little, you risk running out of cash before you achieve the milestones needed to go back to investors again. Meanwhile, understanding the ins-and-outs of various financing instruments — convertible notes, simple agreements for future equity (SAFEs), equity rounds — and their long-term implications can be daunting. (We break down each of these financing options and their implications later in the article.)

So how should you go about it? Start with good forecasting, do a fair amount of math and get help on cutting through the legalese.

Raising capital strategically: How much is too much?

You’re going to get conflicting advice on this, with some people telling you to raise as much money as you can. The right answer will hinge on factors like economic conditions (bull run or downturn) and how much buzz your startup has generated with investors.

From a dilution perspective, the answer is clear: Raise only what you truly need to reach your next significant milestone. The money you raise early on will be the most expensive money you ever take. Why? Because investors get a larger ownership stake for each dollar invested when your company valuation is still relatively low. This holds true even with convertible notes or SAFEs, which defer the equity decision but still ultimately result in dilution.

While a high valuation can minimize the dilution difference between raising smaller amounts via notes versus larger equity rounds, the impact becomes more significant if your valuation decreases in later rounds. Before seeking funding, create a realistic financial projection outlining the costs required to achieve your next major milestone — the point where your company is less risky and more valuable to future investors.

Choosing the right funding instrument for your startup

SAFE or convertible note? Don’t overthink it. Both a SAFE and a convertible note are ways to raise early-stage capital without setting a specific valuation for your company up front. They both offer a way to postpone the decision of how much equity investors receive until a later priced round.

• Convertible note: Essentially a short-term loan that converts into equity during a future funding round, it typically includes an interest rate and a maturity date. This instrument can be beneficial for bridging funding gaps but introduces debt into the company’s financial structure.
• SAFE: This agreement grants investors the right to future equity but without interest or a maturity date. Think of it as a streamlined version of a convertible note without the complexities of debt.
• Venture debt: This is another option to consider, especially after an equity round (like Series A or later). It’s a loan specifically designed for high-growth startups, often used to extend the runway between equity rounds or to finance specific projects. Venture debt does accrue interest and requires repayment, but it minimizes equity dilution compared to raising more equity capital. However, it’s usually not available to very early-stage companies before they’ve secured significant equity funding. This funding mechanism is best suited for early-stage companies backed by venture capital funds.

Like a convertible note, a SAFE entitles the holder to shares, often at a discount to the first priced round. Unlike a convertible note, a SAFE doesn’t command interest and has no maturity date. SAFEs, popularized by Y Combinator, have become increasingly common due to their simplicity and readily available templates. 

But keep in mind that if the terms are not out of the ordinary, going with one or the other won’t materially change your startup’s ownership structure in the long term.

Avoid excessive dilution with convertible notes and SAFEs

As you raise pre-seed funding from friends, family and angels, using convertible notes or SAFEs makes perfect sense. Either allows you to get going quickly, without having to put a precise value on your company. Because of the added risk they assume, note and SAFE holders will typically get a discount when you conduct your first priced round.

But don’t go down this road for too long. As the amount you raise through these instruments grows, so does the risk of significant dilution of ownership if you raise a priced round at a high valuation. Say you’ve netted $500,000 through SAFEs or convertible notes, and when it comes to a priced round, you can only command a $3 million post-money valuation. Your note holders will own more than 20 percent of the company after accounting for the discount.

The last thing a founder wants to do is give away 40, 50 or 60 percent of the company before they’ve even raised a Series A funding round.

Valuation caps’ impact on equity dilution

Valuation caps are a way for note or SAFE holders to protect themselves against the dilution that would come from a startup raising a priced round at a high valuation, basically locking in a minimum future equity stake.

A $5 million cap, for instance, would mean that a SAFE or note holder would own the same percentage of the company for any amount raised at or above the cap. Raising below that amount will cause more dilution.

Managing employee equity pools for long-term success

You’ve raised your money; now you’ve got to build your startup team. But be mindful of the cost. If you give away too much to attract specific people, you end up diluting yourself and your investors more than you need.

Most startups reserve between 10 percent and 20 percent of equity for their option pools.

As you divide those pools among the staff you need, it’s worth thinking about how much you give to key employees early on. As a rule of thumb, a VP of engineering or head of sales who joins at the earliest stages might get between 1 percent and 2 percent. Other senior roles may warrant half a percent.

Negotiating pro-rata rights and avoiding super pro-ratas

You’ve just gotten a marquee investor interested, but as a condition of their investment, they insist on reserving the right to increase their stake in your company in future rounds, an arrangement known as super pro-rata.

While standard pro-rata rights, which allow investors to maintain their current share of ownership, serve as protection from too much dilution and are common, super pro-ratas could have a huge downside for your company, as they may deter new investors from coming in. Many later-stage funds have target ownership stakes and won’t invest unless they end up with at least a 10 percent to 15 percent stake, for example.

The math behind equity dilution

Understanding the math of equity dilution is crucial for both founders and investors. It empowers you to make informed funding decisions, forecast future ownership, negotiate effectively with investors and manage employee equity wisely. By mastering these calculations, you can avoid unexpected surprises and strategically plan for your startup’s growth. Let’s explore some practical examples to illustrate how dilution works in real-world scenarios.

Startup equity dilution by the numbers: Practical scenarios

To show how convertible notes and SAFEs can impact dilution over the long term, we traced the percentage of a company that a founder owns through two different scenarios. In each case, everything after the seed investment is the same.

Scenario 1: Raising $2.5 million at a $10 million post-money valuation
(Notes have a 20 percent discount and $8 million cap.)

Scenario 2: Raising $1.5 million at a $5 million post-money valuation
(Notes have a 20 percent discount and $8 million cap.)

Tools for calculating equity dilution: Simplifying the process

While there are many equity calculation tools available, two stand out for their widespread use and reliability:

1. Carta: This comprehensive equity management platform is used by thousands of startups and investors and offers robust cap table management and scenario modeling tools.
2. AngelCalc: This free, simple web-based calculator is great for quick equity dilution calculations and modeling multiple funding rounds.

These tools can help founders understand and plan for equity dilution throughout their startup journey.

Balancing fundraising and dilution: A strategic approach

Much of the advice we’ve discussed amounts to this: Do your best to understand what you are getting yourself into, understand contractual terms and understand the math. Strategic financial planning is key to minimizing dilution while maximizing your startup’s potential.

Once you’ve done all your homework, move quickly. Don’t waste time optimizing for a percent more here or a few thousand dollars more there. After all, you have a startup to run.

Remember, while equity dilution or dilution of ownership is a necessary part of growing a startup, careful management can help you maintain control and maximize the value of your company. Always consider the long-term implications of your fundraising decisions and seek advice from experienced professionals when needed.
