Equity Grants and Notional Value in Early-Stage Companies
The Founder-FDE arbitrage is the gap that appears when the same skills are compensated differently in a founder role than in an FDE role.
One Engineer, Two Pay Figures
Imagine a single engineer whose pay figures look almost unrelated from one stage of a career to the next. In one period, the total earned over four years works out to roughly $48,000 a year. In the period that follows, the starting cash salary alone is $245,000. Nothing about the person's ability changed between those two numbers. The question this article answers is why the same working skills can be priced so differently depending on the role a person holds, and what that difference reveals about how the labor market values them.
Keep this single engineer in mind as we go. The source follows one composite case it calls Daniel. Because Daniel is a composite illustration rather than a documented individual, treat his figures as a teaching model of a pattern, not as a claim about any specific real person.
Separating the Person from the Role
The Founder-FDE arbitrage is the gap that appears when the same skills are compensated differently in a founder role than in an FDE role.
A useful way to hold this idea is to separate two things people often blend together: the person and the role. The arbitrage does not claim that a founder becomes a better engineer when hired as an FDE. It claims that the market prices a particular bundle of abilities differently when that bundle appears inside a founder's company than when it appears inside an FDE function at another company.
Tracing the Founder Phase
The source tracks the founder phase first. Over four years, from 2020 to 2024, the composite founder co-started a developer-tools company. The company reached approximately $1.2 million in annual recurring revenue, but the team concluded that its market position was not strong enough to raise a Series A. The founders shut the company down and returned remaining capital to investors.
Averaging the founder-era pay
Total compensation across the whole founder stretch, including a partial liquidation, came to approximately $190,000 over four years. What was the average per year, and how does that compare with the source's framing?
- 1Identify the total
The source gives the whole-stretch total as approximately $190,000. This total already includes a partial liquidation, so it is not a clean salary figure.
- 2Divide by the number of years
Four years from 2020 to 2024 gives $190,000 divided by 4, which is $47,500 per year.
- 3Round to the source's figure
Rounded, this matches the source's description of roughly $48,000 a year for workload the source describes as equivalent to senior engineering.
About $48,000 a year, a figure that the source uses as the founder-era baseline.
The Founder-to-FDE Pay Shift
Six weeks after the shutdown, the same person joined a Series B vertical AI startup as its third FDE. The starting cash compensation was $245,000. An equity grant was also part of the offer. At the company's valuation at that time, the grant was projected to be worth about $700,000 over four years, provided the company tracked to its plan. Notice that these are three different kinds of number: a founder-era average, a cash salary, and a projection. The diagram below places them side by side.
Why an Equity Grant Is Not Cash
The equity grant is the part of the offer that most often gets misread. The source is explicit that it was a projection, not cash. Its value depended on the company tracking to its plan, and its status changed as the company's valuation changed over time.
By the eighteen-month mark, the company had raised a Series C at a higher valuation, which made the original projection an underestimate. The source reports that the notional value of the equity stake came to more than the person's entire founder-era compensation in every year, before any cash was counted. The word notional matters here: it describes a value calculated on paper, not a sum deposited into an account.
The diagram below traces how a grant moves from a projected figure to spendable money. The cash value appears only at a liquidity event, so the path has to pass through that step before the number becomes cash.
The Four Layers Stacked Under the Gap
The source explains the gap through a four-layer argument. Each layer names a different reason the market pays more for the same person in the FDE function. The layers are not separate paychecks that add up in a formula. They are stacked explanations, all sitting under the single arbitrage they jointly account for.
Misreadings of the Arbitrage
Common mistake Treating the projected equity value as guaranteed cash
What it looks likeAdding the projected $700,000 equity grant to the $245,000 starting salary as if it were money paid out in the first year.
Why it failsThe source says the grant was a projection, not cash, and its value depended on the company tracking to plan. Cash value appears only at a liquidity event.
Do this insteadKeep the cash salary and the notional equity value in separate columns, and label the equity as a projection until a liquidity event occurs.
Common mistake Concluding that the person became a better engineer
What it looks likeReading the jump from roughly $48,000 a year to $245,000 in cash as proof that the skills improved.
Why it failsThe arbitrage explicitly separates the person from the role. The ability bundle is the same; the market prices it differently in each role.
Do this insteadDescribe the change as a difference in how the same skills are priced in two roles, not as a change in the person's ability.
Common mistake Assuming the projection is fixed
What it looks likeTreating the original $700,000 figure as the final value of the grant after the company raised a Series C at a higher valuation.
Why it failsThe source reports the later valuation made the original projection an underestimate.
Do this insteadRecognize that notional value moves with the company's valuation and is not a stable number.
Common mistake Comparing founder-era totals with cash salaries without first noting that the founder total includes a partial liquidation
Checking the Ratio and the Projection
Using only the source figures, calculate how many times larger the FDE starting cash salary is than the founder-era average of about $48,000 a year. Then explain why the equity grant should not be added to that salary as if it were cash received at signing.
Hints
- Divide the FDE starting cash of $245,000 by the founder-era average of about $48,000.
- The source describes the ratio as roughly five times.
- Ask what the source says about whether the equity grant was cash, and what has to happen before its value becomes spendable.
What do you think happens?
At the time of signing, is the projected $700,000 equity grant cash the person can spend?
Reveal answer
No, it is a projection whose cash value appears only at a liquidity event
The source states the equity grant was a projection, not cash. Its value depended on the company tracking to its plan, and its cash value comes only when a liquidity event makes it spendable.
Keeping the Three Numbers Apart
- 1The Founder-FDE arbitrage is the gap between how the same skills are compensated in a founder role and in an FDE role; it separates the person from the role.
- 2In the source's composite case, founder-era pay was about $48,000 a year, while FDE starting cash was $245,000, roughly five times larger.
- 3The equity grant was a projection of about $700,000 over four years, not cash, and its notional value rose above the original projection after a higher valuation.
- 4The source names four layers (talent spread, services-to-software substitution, complexity premium, and retention math) that together explain the gap, without quantifying each layer's share.
