Dividing equity in a startup influences the company's future direction. A well-structured startup equity split acknowledges each founder's contributions, thereby encouraging fairness and commitment.

It also reassures investors that the founding team has thoughtfully addressed ownership; this boosts the startup's credibility.

However, determining the right equity split comes with its challenges. Founders often bring different levels of experience, capital, and effort, making it difficult to quantify each person's value accurately.

Disparities in equity distribution may lead to resentment and disputes among founders, thereby hindering the company's progress. This article will discuss how to divide equity in a startup to overcome these challenges.

What is Equity in a Startup?

Startup equity refers to the ownership stake individuals hold in a company, usually expressed as a percentage of shares.

Founders, employees, investors, and advisors may receive equity, aligning their interests with the company's success. As the startup grows and achieves milestones, the value of these equity shares can appreciate, leading to significant financial rewards for equity holders.

 

How Startup Equity Works

Equity distribution in a startup is delineated through shares, which constitute the company's total ownership. The allocation of these shares determines each stakeholder's ownership percentage.

For instance, if a startup issues 1,000 shares and a founder holds 250, they possess a 25% ownership stake.

Valuation helps us understand the worth of these shares. A startup's valuation reflects its perceived market value, influencing the price per share. This valuation is significant during fundraising, as it dictates the equity investors receive in exchange for capital.

For example, if a company is valued at $1 million and has 1,000 shares outstanding, each share would be valued at $1,000.

Equity vs. Salary: Why Do Startups Use Equity Compensation?

Startups often operate with limited cash flow; this makes it challenging to offer competitive salaries. To attract and retain top talent, they may offer equity compensation—granting employees partial ownership in the company.

This approach not only conserves cash but also aligns employees' interests with the long-term success of the startup. Equity compensation can be enticing, as it offers the potential for substantial financial gain if the company prospers.

However, it's important to recognize the inherent risks. The value of equity relies on the company's success, and there's no guaranteed financial return. Therefore, individuals should weigh the potential rewards against the uncertainties when considering equity as part of their compensation package.

Types of Equity in Startups

It’s important to understand the various types of equity in a startup as this helps with effective equity distribution among stakeholders. Here are the main categories of equity in startups:

Founder Equity

Founder equity represents the ownership stake allocated to the startup's founders. This form of startup ownership reflects the initial commitment, vision, and risk undertaken by the founders.

To determine the division of founder equity, factors such as individual contributions, roles, responsibilities, and prior experience must be considered.

Employee Equity

Employee equity is designed to attract and retain talent by offering employees a share in the company's potential success. Common forms include stock options and Restricted Stock Units (RSUs):

Stock options grant employees the right to purchase company shares at a predetermined price after a vesting period. They are often used to incentivize long-term commitment and performance.

RSUs are company shares given to employees as part of their compensation. They vest over time, meaning employees earn the right to the shares after meeting certain conditions, such as tenure or performance milestones.

An equity calculator can help you determine appropriate equity grants for employees based on their role, experience, and contribution to the company.

Investor Equity

Investor equity refers to the shares allocated to external parties who provide capital to the startup, such as venture capitalists and angel investors. In exchange for their investment, these investors receive a portion of the company's ownership, which may come with specific rights and preferences.

The amount of equity offered depends on the valuation of the startup and the amount of capital invested. Structure these deals carefully to balance the need for funding with the desire to maintain control over the company.

Advisory Equity

Advisory equity is granted to mentors, industry experts, or advisors who provide strategic guidance, valuable connections, or specialized expertise to the startup.

Compensating advisors with equity aligns their interests with the company's success and can be a cost-effective way to access high-level guidance without immediate cash expenditure.

The percentage of equity offered to advisors depends on their involvement and the value they bring to the company.

Benefits of Equity in a Startup

A well-structured startup equity split offers the following benefits:

Incentivizing Employees and Team Members

Offering equity as part of compensation packages attracts and retains top talent by providing employees with a tangible stake in the company's future success.

Early-stage startups often face budget constraints that limit their ability to offer competitive salaries. By granting startup shares, employees are motivated to contribute effectively, knowing their efforts directly impact the company's valuation and their personal financial gain.

This approach aligns individual performance with organizational success, thereby encouraging a committed and driven workforce.

Aligning Interests Among Stakeholders

Equity distribution ensures founders, employees, and investors share a common goal: the company's growth and profitability.

When stakeholders have a vested interest through co-founder equity or employee stock options, it creates a collaborative environment where decisions are made with the collective benefit in mind. This alignment reduces conflicts and promotes a unified vision.

Preserving Cash Flow

Startups often operate with limited cash reserves. By compensating team members with equity instead of high salaries, companies can conserve cash for critical operations, research and development, and market expansion.

This strategy allows startups to invest in growth initiatives while still rewarding employees, thereby balancing immediate financial constraints with long-term incentives.

Encouraging Long-Term Commitment

Implementing vesting schedules and performance-based equity rewards encourages team members to remain with the company over extended periods. Vesting schedules usually require employees to stay with the company for a predetermined time before they can fully own their equity shares.

This structure promotes loyalty and reduces turnover, ensuring the startup retains experienced personnel crucial for its development. Also, performance-based equity grants motivate employees to achieve specific milestones, thereby linking their compensation to the company's success. 

Who Gets Equity in a Startup?

Let’s take a look at who receives equity in a startup and what is considered when allocating it.

Founders and Co-Founders

Founders are the architects of the startup, bringing the initial idea to life and investing significant time, effort, and often personal capital. As such, they hold the majority of the company's equity.

When multiple co-founders are involved, establish a fair startup equity split that reflects each individual's contributions, responsibilities, and commitment. Factors to consider include:

  • Time Invested: The amount of time each founder dedicates to the startup.
  • Capital Invested: Personal financial contributions made by each founder.
  • Expertise and Skills: Unique skills or industry knowledge that each founder brings.
  • Risk Assumed: The level of personal or financial risk each founder undertakes.

For instance, in a startup with two co-founders, an equal 50/50 split might seem straightforward. However, if one founder has invested more capital or possesses the required expertise, a different distribution may be warranted.

Open and honest discussions among co-founders are necessary to determine a fair split that acknowledges past contributions and future roles.

Early Employees

Early employees transform a startup's vision into reality. To attract and retain top talent, especially when cash compensation may be limited, startups often offer equity as part of the compensation package.

This not only incentivizes employees but also aligns their interests with the company's growth.

A typical equity distribution for early employees might look like:

  • C-Suite Executives: Approximately 5% equity.
  • Vice Presidents: Around 3% equity.
  • Senior Engineers or Product Developers: About 2.5% equity.
  • Experienced Business Development Employees: Roughly 0.35% equity.
  • Sales and Administrative Staff: Approximately 0.2% equity.

These percentages depend on the startup's stage, valuation, and the specific roles and contributions of the employees. Implementing a vesting schedule, often over four years with a one-year cliff, ensures equity is earned over time, thereby encouraging long-term commitment.

Investors

Investors provide the capital necessary for growth and, in return, receive equity in the company. The amount of equity offered depends on the investment amount, the startup's valuation, and the stage of funding.

In most cases, during seed funding rounds, startups might allocate up to 25% of equity to investors, with this percentage decreasing in subsequent funding rounds as the company's valuation increases.

As a founder, consider how much equity to offer to maintain control and ensure sufficient ownership remains for future funding rounds and employee incentives. An equity calculator can help you model different funding scenarios and their impact on ownership percentages.

Advisors and Mentors

Advisors and mentors contribute valuable expertise, industry connections, and strategic guidance that can influence a startup's growth. Compensating them with equity acknowledges their contributions and incentivizes their ongoing involvement.

Standard equity allocations for advisors usually range from 0.25% to 1%, depending on the advisor's level of involvement, experience, and the stage of the startup. These equity grants are often subject to vesting schedules to ensure continued engagement.

Methods for Dividing Equity in a Startup

Determining how to divide equity in a startup is an important decision that can influence the harmony among its founders. There are different, each with its own merits and considerations. Below, we discuss five methods for equity distribution:

Equal Split Method

In this approach, equity is divided equally among all founders. For instance, in a two-founder startup, each would receive 50% of the equity.

Pros

  • Easy to calculate and implement.
  • Promotes a sense of equality and unity among founders.

Cons

  • May not account for different levels of contribution, commitment, or expertise, potentially leading to disputes.
  • Equal ownership can result in stalemates if founders disagree on key decisions.

For instance, the co-founders of BlackBuck, an Indian logistics startup, opted for an equal equity split despite differing levels of experience and financial investment. They believed that equal ownership would encourage unity and commitment, which contributed to their success.

Dynamic Split Method

This method allocates equity based on each founder's ongoing contributions, such as time, capital, expertise, and other resources.

Pros

  • Equity distribution evolves to reflect actual contributions over time.
  • Encourages founders to remain committed and actively contribute to the startup's success.

Cons

  • Requires continuous assessment and documentation of each founder's contributions.
  • Subjectivity in evaluating contributions can lead to disagreements.

For instance, in the early days of Facebook, Mark Zuckerberg, Eduardo Saverin, Andrew McCollum, Dustin Moskovitz, and Chris Hughes had different roles and commitments.

Initially, Zuckerberg received 28% equity due to his central role, while others received between 5% and 10%. Over time, as contributions and roles changed, so did the equity distribution among the founders.

Slicing Pie Model

Developed by Mike Moyer, the Slicing Pie model offers a formulaic approach to dynamic equity splitting. It assigns value to various contributions (time, money, intellectual property) and adjusts equity shares in real-time based on these inputs.

Pros

  • Equity reflects the current value of each founder's contributions.
  • Accommodates changes in contribution levels seamlessly.

Cons

  • Requires meticulous tracking and valuation of all contributions.
  • Education and agreement among founders may be required to adopt the model.

Fixed Percentage Model

In this approach, equity percentages are predetermined based on each founder's role, experience, or initial contributions. For example, a CEO might receive 40%, a CTO 35%, and a COO 25%.

Pros

  • Establishes clear expectations from the outset.
  • Acknowledges the varying levels of responsibility and expertise among founders.

Cons

  • Does not account for changes in contribution levels over time.
  • Fixed allocations may lead to dissatisfaction if perceived as unfair as the company evolves.

For instance, Microsoft's original equity split between Bill Gates and Paul Allen was 60/40, reflecting their respective roles and contributions at the company's inception. Gates, as the primary driver of the business, received a larger share, while Allen's significant technical contributions were also acknowledged.

Performance-Based Equity Distribution

This method ties equity allocation to specific milestones or performance metrics. Founders earn their equity shares by achieving predefined goals, such as product development stages, revenue targets, or user acquisition numbers.

Pros

  • Ensures equity is granted in alignment with the company's strategic objectives.
  • Reduces the risk of allocating equity to underperforming founders.

Cons

  • Defining fair and measurable performance metrics can be challenging
  • May incentivize founders to prioritize immediate results over long-term growth.

For example, Airbnb's co-founders, Brian Chesky, Joe Gebbia, and Nathan Blecharczyk, implemented a hybrid equity split that combined an equal initial split with a performance-based vesting schedule.

This approach ensured each founder's equity stake was contingent upon their ongoing contributions and achievement of specific milestones, aligning their interests with the company's long-term success.

Startup Equity Distribution Example

Let’s consider a startup with three co-founders, a group of early employees, and external investors. The initial equity distribution might look like this:

Stakeholder Percentage (%) Notes
Founder 1 33.33 CEO, primary investor
Founder 2 33.33 CTO, technical lead
Founder 3 33.33 CMO, marketing lead
Employees 10 Stock options pool
Investors 20 Seed round investors

Note: The percentages are illustrative; actual distributions should align with the specific contributions and agreements of the founders, employees, and investors.

Equity Dilution Over Time

As the startup progresses and secures additional funding, equity dilution occurs, thereby affecting the ownership percentages of existing stakeholders.

For example, in a subsequent funding round, investors might inject capital in exchange for a 15% equity stake. This investment dilutes the ownership of existing shareholders proportionally.

Stakeholder Pre-Funding (%) Post-Funding (%) Dilution (%)
Founder 1 33.33 28.33 5.00
Founder 2 33.33 28.33 5.00
Founder 3 33.33 28.33 5.00
Employees 10 8.50 1.50
Investors 20 35.00 15.00

Note: The dilution percentages are simplified for illustration; actual dilution effects depend on the terms of the funding agreement and the valuation of the company at the time of investment.

Founders and early stakeholders must plan for equity dilution to maintain desired control and benefit from the company's growth. Use tools like an equity calculator to model different funding scenarios and their impact on ownership distribution.

Wrapping Up

Establishing a fair and transparent equity distribution is important for the success and harmony of a startup. It not only aligns the interests of all stakeholders but also builds trust and commitment.

To prevent misunderstandings and legal disputes, formalize equity agreements through legal documentation. Legal frameworks, such as founders' agreements and stock purchase agreements, outline rights, responsibilities, and ownership stakes, providing clarity and protecting all parties involved. 

As startups grow, so do the roles and contributions of their team members. Hence, regularly review and adjust your equity allocations so that ownership can accurately reflect current contributions and responsibilities.

FAQs

How much equity should a founder get in a startup?

The amount of equity a startup founder should get depends on the number of co-founders, individual contributions, and the stage of the company. In the early stages, it's common for founders to retain a significant portion of the company's equity to maintain control and incentivize their commitment.

For startups with multiple co-founders, equity splits can range widely. A 2015 study found that only 31.5% of two-founder teams split equity equally, with this figure increasing to 45.9% by 2024. This trend suggests a growing preference for a more balanced equity distribution among co-founders.

How do you structure founder equity?

Here are the steps for structuring founder equity:

  • Define equity types
  • Implement vesting schedules
  • Determine equity splits among founders
  • Address potential dilution
  • Formalize agreements and documentation
  • Establish a clear capitalization table (cap table)

How much do founders get diluted?

Typical dilution percentages by funding round include:

  • Seed Round: Founders may experience dilution between 10% and 25%.
  • Series A: Dilution often ranges from 15% to 25%.
  • Series B: Dilution typically falls between 10% and 20%.
  • Series C and Beyond: Dilution per round generally decreases, ranging from 5% to 15%.

These percentages are approximate and depend on the company's valuation, the amount of capital raised, and negotiations with investors.
