Examining the Risks of Concentration in Startup Equity for Founders and Employees

Startups & Funding Sep 01, 2026 Charlie O'Donnell

Exploring the complexities of equity in startups, this piece highlights the risks of concentration and the importance of understanding your worth and options.

Examining the Risks of Concentration in Startup Equity for Founders and Employees

What if you were handed the cash equivalent of your vested equity today — say, two million dollars reflecting your startup's latest valuation? Would you then reinvest it all into your current Series D funding? It's a thought-provoking question that most founders and employees are unlikely to answer with a resounding yes.

Diversification is a common investment strategy, and it's particularly relevant in the volatile world of startups. Many would consider spreading that cash among competitors in the same space—perhaps companies focused on agentic e-commerce or automated AI-driven go-to-market strategies. But for founders, this amount can often reach ten times more, increasing the stakes significantly.

The reality is stark: few people would opt to rebuild their portfolios with equity from a single company. While an IPO might yield substantial returns and a sense of luck, the risks associated with not diversifying can be heavy. The question looms—if the company underperforms, will you face regret for not having diversified your holdings?

The Challenge of Exercising Options

For many employees whose compensation is tied to stock options, it’s essential to understand just what that means. Equity options grant you the right to acquire shares but don’t translate into actual ownership until you pay to exercise them. This conversion can be financially burdensome, especially for early employees at companies that have seen multiple rounds of valuation increase. The cost to exercise these options can rival a substantial down payment on a home, leaving employees in a bind.

Additionally, there’s the tax implication to consider. Exercising Incentive Stock Options (ISOs) can trigger Alternative Minimum Tax (AMT) based on the difference between the strike price and current valuation. If the company goes public, that AMT can be manageable, but if the company stagnates or declines, employees may find themselves holding shares that cost more than they're worth, leading to significant financial distress.

Shifting Roles in Engineering

The landscape of engineering roles has transformed decennially, with frequent shifts in what skills are valuable. Where engineers used to be defined by their specific coding skills, today’s high-value employees are recognized for their judgment and system-level thinking. The frequency of these changes has accelerated in recent times, especially with the rise of AI, which takes over routine coding tasks. Now, the rare talent is someone who can envision what products to create, when to pivot, and understand the bigger picture of the business.

Today's engineers are often likened to mini-founders within organizations, capable of creating significant value from relatively fewer resources. This raises a compelling question: why invest deeply in a company's equity when you could harness your skills to start your own venture?

Solo entrepreneurship is more feasible than ever. A savvy engineer, armed with just a laptop and the right tools, can launch a profitable company that used to require an entire team and complex management structures. The blurred lines between self-employment and working for a startup mean that individuals now evaluate the opportunity cost of staying within someone else's company.

An Ecosystem of Secondary Markets

The growing complexity in the startup world has led to an increase in secondary markets where employees can sell their shares. Various secondary funds and family offices are eager to acquire equity from early employees. However, as with anything, some purchasers are fair and some can take advantage of employees’ needs for liquidity; thus, due diligence is crucial.

For founders, the question becomes whether to allow employees to exit with some cash while realizing it can impact the company's valuation and negotiation power in subsequent funding rounds. Allowing liquidity to employees can prevent them from leaving purely for financial reasons, but it can also complicate share prices and future company valuations. The decision is nuanced and requires careful consideration.

Understanding Your Position

Navigating the intricacies of equity is rarely straightforward. The tax implications can vary widely, and timing can create significant challenges. While some employees may have the opportunity to sell at the right moment, others may lose out completely based on inadequate understanding or poor timing.

Before making decisions about whether to exercise options or how to manage equity, it’s crucial to assess the actual worth of what you hold, examine all available routes for monetizing that value, and consider whether you'd willingly take on this concentrated risk today. Without this clarity, you're essentially letting circumstances dictate your financial future.

To delve deeper into these topics, I’m hosting a webinar with Qapita focused on secondaries and employee equity, aimed at both engineers holding the paper and founders grappling with the implications of these arrangements.
