Founding Jobs at Series B Startups

What changes when you join at Series B

A Series B company has usually shown that customers will pay for what it sells, and is raising money to grow faster: more customers, more markets and more people. You join a business with revenue, a working team and some settled processes, but much of the company it plans to become hasn’t been built yet. Expect more structure than at seed or Series A, and fewer open questions about what the product is.

What “founding” means at Series B

At Series B, a founding role is usually the first hire in a new function, product line, team or region: the first partnerships lead, the first data hire, or the first person in a new market. You won’t shape the whole company, but you may set how your function works for years. Ask what already exists in your area, who you report to, and whether you’re expected to build a team or stay hands-on.

What to look at before you apply

• Scope: which decisions, budget and hiring you own, and where a founder or functional leader stays involved.
• The plan for the round: what the money is meant to achieve, and what the company needs to show before it raises again.
• Team: how many people work in your function today, and the hiring plan for the next 12 months.
• Process: what is already defined, such as tools, targets and reviews, and what you’re expected to create.

How equity changes at Series B

Grants at Series B are usually a smaller percentage of the company than at seed, but each share costs more. The strike price is set by the 409A valuation of common stock, which rises as the company does, so exercising your options takes more cash. In Equitybee’s 2026 grant report, the median new-hire grant at Series B was worth $51K at grant-date fair market value, against $33K at seed and Series A. Because the strike price is usually set at that value, the figure is roughly what it would cost to buy the shares, not what they will be worth.

More investor money also sits ahead of you. Each preferred round usually carries a liquidation preference that is paid before common stock in a sale. Ask for the total preference amount, the latest 409A valuation, and whether the company has run, or plans, a tender offer that lets employees sell some shares before an exit.

Compare salary and equity using current evidence

Start with the compensation shown on each current listing rather than assuming one Series B package. Verified Equity is an employer-disclosed numeric range. Estimated Equity is a FoundingHunt Benchmark: an estimate by role and stage, not an employer offer. Compare cash and equity together with the Offer Comparator, and confirm the percentage on a fully diluted basis, the vesting schedule, the exercise window and how future rounds could dilute your ownership.

Before you apply

1. Ask how much runway the round provides and which milestones the next raise depends on.
2. Confirm why this role is open now, and whether you’d join an existing team or start the function.
3. Understand the reporting line, your decision rights and your hiring budget.
4. Ask for the total liquidation preference and any history of tender offers or secondary sales.
5. Review the salary, equity source, vesting, exercise window, location and working expectations in the listing and the offer.
