To negotiate developer equity, treat the offer like a financial instrument, not a gift. Ask for the option count, strike price, post-money valuation, and your fully diluted percentage in writing. Benchmark against Pave (0.33% median for a founding engineer, 0.62% at the 75th percentile). Then negotiate the vesting cliff, post-termination exercise window, and refresher policy, not just the headline number. This post is a framework, not legal or tax advice.
Most engineers see a number that ends in shares or a percentage, then either accept because it sounds generous or counter on salary because that's the lever they understand. Equity gets treated as a lottery ticket.
It isn't. It's a financial instrument with a strike price, vesting schedule, exercise window, tax profile, and a denominator that shrinks every funding round. The founder has spent months thinking about it. You probably have not. The gap between an untrained negotiator and a prepared one is huge, and most of the prep is reading.
Before you negotiate, you need four numbers. If the founder won't share them, that's the first walk-away signal.
your options / fully diluted count.With those four numbers, you can compute a meaningful expected value. Without them, you are guessing.
Here is the math everyone gets wrong. A recruiter says "your grant is worth $400k." That figure usually multiplies your options by the preferred price. The honest math subtracts the strike price first: (preferred price minus strike price) times option count. If your strike is $2 and the preferred is $4, your "grant" on 100,000 options is $200k of latent value, not $400k, and you only realize it if the company exits above the preferred price after taxes, dilution, and a liquidation preference stack.
Pave's compensation data, drawn from real cap tables, gives the cleanest picture for early-stage engineering equity.
| Stage | 50th percentile | 75th percentile | 90th percentile |
|---|---|---|---|
| Founding engineer (sub-50 employees) | 0.33% | 0.62% | 1.24% |
| First non-founder hire (seed) | 0.5% | 1.0% | 2.0% |
| Senior eng, Series A | 0.2% | 0.4% | 0.8% |
| Senior eng, Series B | 0.1% | 0.2% | 0.4% |
| Senior eng, Series C+ | 0.05% | 0.1% | 0.2% |

The right benchmark depends on whether you are employee #2 or employee #50, and whether the company has raised at $5M post or $50M post. For a fuller view of how founders think about the same numbers from the other side, our companion guide on how much equity to give a developer co-founder or first hire walks the founder math.
A 0.5% offer at a $10M post-money seed is roughly $50k of paper value at grant. A 0.5% offer at a $100M Series B is $500k of paper value. Same percentage, ten times the expected value. Anchor on the dollar number, not the percent.
Your percentage today is not your percentage at exit. Carta's data shows typical dilution of 15-25% per priced round, plus an option pool top-up at each round that the existing shareholders absorb. Most venture-backed startups raise three to four rounds before exit.
Here is a worked example. You join at seed with 0.5%. The company raises a Series A with 20% dilution and a 10% pool refresh. After the round, your stake is 0.5% times 0.8 times 0.9 = 0.36%. After a Series B with similar terms: 0.36% times 0.8 times 0.9 = 0.26%. After a Series C: 0.26% times 0.8 times 0.9 = 0.187%. You now hold 0.187% at exit, not 0.5%.
If the company exits at $500M, your stake is worth $935k pre-tax, before liquidation preferences and any management carve-out. That is the real number to negotiate against, not the seed-stage paper value.
The fix is not to refuse dilution (you can't) but to negotiate refresher grants in writing at offer time. A refresher is a new option grant, typically issued annually or at promotion, that offsets dilution and rewards retention. Carta's research shows top startups issue refreshers worth 25-50% of the original new-hire grant on a 4-year vest, layered on top of the first grant. If a founder won't commit to a written refresher policy, you should price that uncertainty into your counter.
The headline percentage is one of nine levers. The other eight matter more than most engineers realize.
| Term | Default | What to ask for |
|---|---|---|
| Vesting | 4-year, 1-year cliff | Same, but make sure the cliff is calendar-month based |
| Acceleration on termination | None | Single-trigger on involuntary termination or change of control |
| Post-termination exercise window | 90 days | 7 to 10 years, especially if strike is high |
| Early exercise | Not allowed | Allow early exercise + 83(b) election filing |
| ISO vs NSO | Often NSO above $100k/yr vest | Maximize ISO portion (better tax treatment) |
| Refresher cadence | Discretionary | Written policy: annual review tied to performance |
| Liquidation preference | 1x non-participating preferred | You can't change this, but ask for the cap stack |
| Strike price | 409A at grant | Push to grant before next priced round |
| Definition of cause | Broad | Narrow definition tied to written warning |
The post-termination exercise window is the sleeper item. A 90-day window means if you leave or get fired, you have 90 days to come up with cash to exercise your vested options or you forfeit them. For an engineer with 100,000 vested options at a $4 strike, that's $400k of post-tax cash inside three months. Most people don't have it. They walk away from years of vested upside because of a clause they didn't negotiate. Pinterest, Quora, and many later-stage companies extended their windows to 7-10 years after public pressure. Yours probably hasn't. Ask.
This is the framing the top SERPs miss. As a developer, you have an outside option that founders don't always think about: contract or book yourself out at a known weekly rate. Senior engineers on Cadence book at $1,500 per week, paid Friday. Lead engineers book at $2,000. A junior who does cleanup and doc work books at $500. These are real numbers, not aspirations.
If you take a startup offer at $120k base plus 0.5% equity, you are giving up roughly $30k-50k of cash you could earn freelancing or contracting at senior rates. Multiply that gap by 4 years of vest and you have $120k-200k of foregone cash. Your 0.5% needs to plausibly return at least that much, risk-adjusted, to break even.
Most early-stage equity does not. The base rate for a venture-backed startup reaching a meaningful exit (over $100M) inside 8 years is around 5-10%, and a 0.5% stake at exit (after dilution and prefs) on a $200M outcome is roughly $400k pre-tax. Multiply that $400k by a 7% probability of hitting that outcome and the risk-adjusted value of the equity is around $28k. Less than your foregone cash.
This doesn't mean refuse equity. It means: only accept a cash-and-equity package where the cash-side discount is something you can absorb, and the equity-side upside is large enough that the expected value clears your contracting alternative. If the founder won't move on either, walk and book a senior contract for the year while you find a better-priced opportunity.
Some patterns are red flags worth refusing the offer over, regardless of the number.
Sometimes the smart move is more cash, less equity. Three scenarios.
You have runway constraints (mortgage, kids, family healthcare). Equity does not pay rent. A founder pushing heavy-equity while you carry $4k/mo in fixed costs is not aligned with your risk profile.
The company is at a stage where equity is mostly noise. Series C+ equity is typically RSUs vesting on liquidity events 5+ years away; the cash matters more.
You don't believe the company will exit. If your honest read is the path is narrow, take the cash. Equity in a company you don't believe in is a tax on your career, not an investment.

Thanks for the offer. Before I respond with terms, I want to make sure I'm modeling it correctly. Could you share: (1) the exact option count and strike price, (2) the fully diluted share count as of the last priced round, (3) the most recent preferred share price, (4) the post-money valuation on that round, (5) the company's current monthly burn and runway, (6) the vesting schedule and post-termination exercise window in writing, (7) the option pool size and whether it's pre- or post-money on the last round, and (8) the refresher policy or guidance for years 2-4? Happy to discuss live if easier. I want to come back with a thoughtful counter, not a number pulled from the air.
Founders who respond fully are running a transparent shop. Founders who push back on item (1), (2), or (3) are telling you something important. Listen.
If you are a developer reading this and you've concluded the equity isn't priced right, you have an alternative that didn't exist five years ago: bill your time at a real weekly rate to a vetted founder pool while you keep optionality open.
Cadence is an on-demand engineering marketplace. Every engineer on the platform is AI-native by default, vetted on Cursor, Claude Code, and Copilot fluency in a voice interview before bookings unlock. Founders book by the week at fixed tier rates: junior $500, mid $1,000, senior $1,500, lead $2,000. We pay engineers Friday for the week's work. The platform's senior engineer pool currently sits north of 12,800 vetted developers globally.
If you are evaluating a startup offer right now, browsing the kind of weeks you could book on Cadence is a real-money benchmark for the cash side of your decision. You can take the equity offer, decline it, or counter, and the contracting alternative is a phone call away either way.
The negotiation isn't adversarial. The best founders want engineers who think clearly about equity because those engineers also think clearly about the business. Coming in with the math signals exactly that.
If you are a founder reading this from the other side of the table, Cadence lets you book a senior engineer for a 48-hour free trial before any equity conversation begins. Many of our most successful founder-engineer matches start as paid trials and convert to full-time offers once the fit is proven.
Pave's market data shows the median for a senior founding engineer is 0.33%, with the 75th percentile at 0.62% and the 90th percentile at 1.24%. The right number depends heavily on whether you're employee #2 or #20 and the post-money valuation. Anchor on dollar value, not percentage.
It depends on your runway, your conviction in the company, and your contracting alternative. If you can plausibly bill at $1,500-2,000 per week on the open market, the cash side of the offer needs to clear that floor before the equity premium starts to matter. Use the contracting-rate test in this post to get a real number.
A refresher is an additional option grant, usually issued annually or at promotion, that vests on a new schedule and offsets dilution. Top startups grant refreshers worth 25-50% of the original new-hire grant. Get the policy in writing in the offer letter, not as a verbal promise. Carta's equity refresh research is a good external reference to cite.
It's the period after you leave the company during which you can exercise your vested options before they expire. The default is 90 days. If your strike price is high and you have many vested options, that window can require six-figure post-tax cash on short notice. Negotiate for a 7-10 year window or until grant expiration, especially if the strike is meaningful.
Walk if the founder won't share the post-money valuation, fully diluted share count, or strike price in writing. Walk if the exercise window is sub-90-day with no flexibility and the strike is high. Walk if the refresher policy is purely discretionary and the cash component requires real lifestyle compromise. The job market for senior engineers is liquid; a bad equity offer is not the only option you have.
No. This is a framework for thinking through an equity offer. Stock options have meaningful tax implications (ISO vs NSO, AMT exposure, 83(b) elections) that vary by jurisdiction and personal situation. Before you sign or exercise, talk to a startup-comp lawyer and a tax advisor who has worked with engineering offers.
