The first 10 employees are often the people who determine whether a company gets from product to scale. They take below-market salaries on the assumption that startup equity for early employees will make up the difference. By the time the company raises a series A, those grants are either large enough to concern institutional investors or small enough that the early employees are quietly looking for something else.
Getting early employee equity right isn't about generosity. It's about precision — making decisions in months 3 through 18 that don't create structural problems in year three when they're hardest to fix.
The option pool problem
Most early-stage companies create an option pool as part of their seed round — typically 10% to 20% of fully diluted shares, reserved for future employees. The size gets negotiated with investors, and a larger pool means more dilution for founders at that moment.
The mistake founders make isn't usually in the pool size — it's in having no deployment plan. A 15% option pool sounds adequate until you've hired eight people in the first 18 months and used 12% of it, leaving 3% for the next two years of hiring before your Series A. At that point, you need to expand the pool — which means additional dilution at exactly the moment you're trying to run a clean fundraising process.
When setting the option pool, model out the next 24 months of hires and roughly what each role will require in equity. The exercise usually reveals that the pool is either larger than needed (giving away dilution upfront without needing it) or smaller than needed (creating the expansion problem later). Either miscalibration is avoidable with a simple hiring plan on paper before the seed closes.
Grant sizing by role and stage
There's no universal formula, but there are defensible starting points:
First engineer, pre-product-market fit: 0.5%–2% depending on scope, full-time commitment, and whether they're the only technical hire or one of several. If they're writing all the code and not taking a salary, the upper end is justified.
Early non-technical key hires — head of sales, first marketing hire, operations lead — joining before PMF: 0.25%–1%. These people take real career risk to join a company that may not work. The equity should reflect that.
Later functional hires after product-market fit, when the company risk profile has changed: 0.1%–0.25%. Competitive market-rate compensation starts to apply at this stage; equity is a supplement, not the primary incentive.
The grants that create the most downstream problems are the informal ones — "I told her she'd get 1% because I needed her and didn't want to lose her" — made without documentation, without vesting, and without thinking through how 10 more versions of that conversation compound on the cap table. One undocumented grant is an oversight. Three is a pattern that institutional investors will notice and flag.
Vesting structure for early hires
The same four-year vest with a one-year cliff that applies to founders applies to employees. The cliff matters: it protects the company from someone who leaves in month 11 taking a quarter of their grant with them.
For the first few employees who are taking real risk to join — especially if accepting a salary meaningfully below their market rate — accelerated vesting on a change of control is worth considering. A single-trigger acceleration clause means early employees aren't stranded if the company is acquired two years in. This is a reasonable concession for the people who mattered most in the building phase, and a useful recruiting differentiator when you're competing for talent against companies offering higher base salaries.
Double-trigger acceleration (requiring both a change of control and termination without cause) is more common and tends to be less disruptive at acquisition. For early employees specifically, single-trigger is worth discussing. For the general employee population, double-trigger is standard.
What Series A investors look at
When institutional investors review the cap table at Series A, three things come up consistently: founders still hold meaningful equity (typically 15%+ each for a two-person team), there's enough unallocated option pool to fund 24 months of post-round hiring without an immediate expansion, and there are no unusual grants that suggest informal commitments made outside the formal equity system.
A 3% grant given to an early engineer through a proper grant agreement with vesting is visible on the cap table and explainable. The same 3% given informally as a handshake — without documentation — is a contingent liability that has to be resolved before the round closes. Resolving it during a fundraise is expensive and distracting in a way that proper documentation from the start would have prevented entirely.
Institutional investors encounter messy early-employee equity situations constantly. They don't penalize founders for paying early employees fairly. They penalize founders for creating equity obligations that aren't documented — because undocumented obligations represent unknown risk.
