Option Pool Sizing: From Percentage to Plan

Equity is one of the most powerful instruments available to a tech founder. It aligns incentives, attracts entrepreneurial talent, and creates long-term ownership thinking across the organisation.

Yet when the discussion turns to the size of the option pool, many companies default to market conventions like “10% is standard.”

Market references can be helpful, but copying a percentage without linking it to your hiring roadmap, financing strategy and growth milestones is rarely optimal.

Your option pool sits on the cap table alongside founder and investor shares. Every percentage point impacts dilution, control, future negotiations and ultimately value at exit. Getting it “approximately right” is not enough. It needs to be structurally aligned with your growth plan.

Why Option Pool Sizing Matters More Than You Think

An incorrectly sized option pool has tangible consequences:

  • Too large → unnecessary early dilution for founders before the pool is actually deployed
  • Too small → forced expansions during financing rounds, often at moments when negotiation leverage is limited
  • Poorly structured → inability to attract key hires at critical milestones
  • Lack of forward planning → misalignment between hiring, runway and shareholder expectations

Rather than looking at the option pool as a static percentage, we can view it as a dynamic strategic instrument that evolves with your company’s maturity, risk profile and funding trajectory. Just as you align your commercial investments with your growth targets, your equity allocation should reflect your human capital roadmap.

A Bottom-Up Approach: Start With the Plan

Rather than using a top-down percentage, we like to take a bottom-up approach, So, instead of asking, “What percentage should our pool be?”, the better question is: “Who do we need to hire to reach our next value inflection point?”

A structured bottom-up analysis considers three key variables:

1. Risk Profile of the Hire

Early employees accept significant uncertainty: product risk, funding risk, and execution risk. Equity compensates for that risk and should reflect company maturity.

Typically, early key hires deserve a larger share. As your company matures and risk decreases, the balance shifts. Later hires are often more “cash-heavy” and “equity-light.”If this dynamic is not modelled explicitly:

  • You may under-incentivise early strategic hires.
  • Or you may over-allocate equity later, when it is no longer required to compensate risk.

2. Role, Impact and Seniority

Equity is not a “one-size-fits-all” solution. A CTO successor requires a different allocation than a junior account manager. Building the pool role-by-role forces clarity:

  • What is the expected impact of this hire?
  • What milestone will this role unlock?
  • What is market reality for comparable roles at your stage?

This prevents reactive equity grants and preserves flexibility for truly strategic hires.

3. Financing Horizon and Scenario Modelling

An option pool should be sized for a defined period, typically until the next financing round, plus a decent buffer.

This means modelling:

  • Planned hires until next raise.
  • Potential promotions and refresh grants.
  • Expected investor pool requirements.

Without modelling this explicitly, companies can face higher effective dilution than originally assumed.

Communication: Turning Equity Into a Real Incentive

Even a technically perfect option pool loses effectiveness if your team does not understand its value.

In the startup world, we often talk about “perceived value.” If a candidate only sees a percentage without context, it remains an abstract number that may or may not be worth something one day.

Candidates and employees do not evaluate “0.4%” in isolation. They need context:

  • What is the vesting schedule and why?
  • What dilution can be expected in future rounds?
  • What are realistic exit scenarios?
  • How does their grant compare to future hires?

Equity becomes meaningful when it is embedded in a coherent narrative about company trajectory and value creation.

From Cap Table to Execution Confidence

Founders often carry silent concerns about whether they are structuring their company in a way that will scale, not only commercially, but organisationally and financially.

A thoughtfully designed option pool demonstrates:

  • Clear hiring priorities
  • maturity in capital management
  • Forward planning toward financing milestones
  • Professional governance
