Negotiate a startup offer by explaining what you need, why it matters and which trade-offs you can genuinely make. A clear request gives the company something concrete to consider. Repeated small demands or an invented competing offer make the conversation harder to resolve.
You are discussing the terms of a working relationship, not trying to win every line in a package. Prepare carefully, raise the material issues together and recognise when you have enough information to decide.
This guide is Corellia Talent’s suggested approach for engineers. Start with the three-city compensation guide if you still need to separate cash, equity and benefits.
Understand the whole offer first
Ask for the package and role in writing before making your counterproposal. Confirm base salary, any variable pay, working arrangement, reporting line, scope, start date and equity terms. A misunderstanding is easier to resolve before it becomes a negotiation.
For a bonus, ask how it is calculated, who decides the outcome and when it is paid. For equity, ask for the grant type and terms rather than relying on a headline value. An option is a right to acquire shares under conditions, and the exercise price is part of the decision. [Source 1]
Write down what is confirmed and what is still awaiting approval. A proposed grant, an agreed start date and a possible future review are different kinds of commitment. Keep those distinctions visible when comparing alternatives.
If a figure changes between the advert, interview and written offer, ask for the reason directly. You need to know whether the role changed, the level changed or the earlier information was incomplete.
Choose your priorities before the conversation
Pick the issues that would materially affect your decision. Base salary might be essential because you need a certain dependable income. Scope, remote days or a realistic start date might matter more than a modest increase in equity.
Separate your minimum requirements from your preferences. This helps you avoid trading away something important simply because another part of the offer becomes more attractive during the discussion.
Consider the whole year, not only the first payslip. A one-off payment can help with a transition cost, but it does not change recurring salary. A promised review is useful only when its timing, owner and purpose are clear.
Use the salary guide to understand comparable advertised work in the relevant city. Read the sample and whether a result is observed or modelled. Your case should connect the role’s actual responsibilities with your relevant experience, rather than quoting the highest number you can find.
Make one clear request
Explain your interest, state the adjustment you are seeking and connect it to the decision you need to make. You can be warm and direct without apologising for raising the topic.
For example, you could say: “I’m interested in the role, especially the responsibility for getting the product into customers’ hands. To make the move work, I would need the base salary to be closer to the level we discussed. Is there room to revisit that alongside the equity grant?”
That is suggested wording, not a script you need to perform. Use your own language and the facts of your situation. Give the other person room to explain what is possible and who needs to approve it.
Bring the important issues together. If salary, working pattern and start date all need discussion, list them in the same conversation so the company can consider a complete proposal.
Discuss trade-offs you would actually accept
A useful alternative solves a real constraint. If the company cannot move the base salary, you might discuss a signing payment, different equity terms, a narrower scope or a later start. Do not offer a trade-off just to keep the negotiation moving.
| Topic | Useful question |
|---|---|
| Base salary | Is the constraint the role’s band, budget or assessed level? |
| Equity | Can we review the grant and its terms together? |
| Scope or title | Can the responsibilities and decision rights be clearer? |
| Working pattern | Which days or activities genuinely need us together? |
| Start date | What would a workable handover and joining plan look like? |
| Learning support | What time, budget and access to expertise are available? |
Ask why a constraint exists. A fixed salary band may protect consistency across the team. A proposed office pattern may serve a customer or operational need. Understanding the reason helps you judge whether an alternative would work.
Keep equity separate from spendable cash
Discuss equity as ownership with conditions and risk, rather than as a precise replacement for salary. A larger grant can be valuable to you without meeting the same need as dependable monthly income.
Ask for the fully diluted percentage and the date on which it was calculated, as well as the option count. Confirm vesting, the exercise price, the post-employment exercise window and what happens if the business raises more funding.
US statutory and nonstatutory options have different tax treatment; exercising an ISO can also involve alternative minimum tax. [Source 2] UK EMI treatment depends on the qualifying conditions. [Source 3] The plan and grant documents need to support the explanation you receive.
If the company quotes a potential future value, ask which assumptions produce it. You can discuss upside without letting a hypothetical exit value become the number that makes your household budget work.
Handle deadlines and competing offers honestly
Say when you need to decide and why. If another process is still running, describe its stage accurately. Do not present an interview as a written offer or invent a deadline to create pressure.
If you need more time, ask for a specific extension and explain what remains to be checked. That might be the equity paperwork, a conversation with your future manager or the practical arrangements for a move.
You can also ask the company what its deadline reflects. It may need a start date, an approval or a decision about another candidate. The answer helps you judge whether the timetable is workable.
Avoid turning every response into a new bargaining round. Once the material questions are answered, make the decision you said you were preparing to make.
Know when the answer is enough
A successful negotiation may end with the original offer, an adjusted offer or a respectful decision not to join. The result needs to work for you, even when the company has a reasonable explanation for its limits.
If the revised package meets your requirements, confirm that clearly rather than continuing to test for one more improvement. If it does not, explain the specific gap and close the conversation courteously.
Pay attention to how the discussion is handled. You will disagree about priorities at work as well as about an offer. Clear explanations, accurate follow-up and room for questions are useful evidence of how the relationship might operate.
Confirm the agreement before you move
Ask for the final terms and any approvals still outstanding to be recorded. Read them together with the role scope, not as a separate administrative exercise. Confirm who will answer questions about the grant documents and who owns the joining plan.
For UK roles, the statutory written statement includes specified employment particulars, with the principal statement due on the first day. It is distinct from the employment contract. [Source 4] Your practical aim is to resolve the offer’s important questions before you make commitments around it.
Revisit the questions to ask before joining a startup and the founding engineer brief. A well-negotiated offer should leave you clearer about the work and ready to begin, rather than wondering which promises will survive the paperwork.
