What stage startup should you join?

What is the difference between pre-seed, seed, Series A and Series B?

Stage tells you two things: how many people work there, and whether the company has found something that works yet.

The funding labels are about how much money has been raised, but what matters to you is what that money bought. Pre-seed and seed companies are still looking for product-market fit. The core question (does anyone want this, and will they pay for it) is still open. Series A and beyond have answered that question and are spending the money on scaling something that already works.

Everything else follows from that one difference. Team size, how defined your job is, what you get paid, how much equity you are offered, and how much can go wrong.

How big is the team at each stage?

Under ten people at pre-seed and seed, roughly fifteen to fifty at Series A, and by Series B there are layers between you and the founders.

Headcount is the part you can feel on day one. At pre-seed and seed you are in daily contact with the founders whether you want to be or not. The hierarchy is flat because there is nothing to have a hierarchy about.

At Series A and beyond you will probably report to a head of product or a head of go-to-market, and that person sits between you and the founders. Neither is better. But if being close to the founders is the reason you want a startup job, that reason mostly disappears somewhere around Series A.

How do you find out a company's stage?

It is public information. A plain search usually answers it in thirty seconds.

Funding rounds get announced, so searching the company name with the word funding normally does it. Crunchbase and Dealroom track rounds across most markets and will tell you the stage and the date. The company's own blog or press page is often the most accurate source of all.

LinkedIn is the exception. It shows you headcount, which is a rough proxy, but it does not show funding stage and the employee count is frequently out of date. Do not rely on it.

The date of the last round matters as much as the stage itself. A company that raised a seed round four years ago is a very different proposition from one that raised six months ago, even though both are labelled seed.

How does the stage change the job day to day?

The earlier you join, the wider your job is and the more of it nobody has defined yet.

At pre-seed and seed you are hired as a generalist, whatever the title says. You will see roles called founding engineer, founding product, founding customer success. The word founding is doing real work there: your job is the thing you were hired for, plus whatever else needs doing.

A concrete version. A founding customer success hire is on a call with a client, and the client gives feedback on the product. That person is now expected to carry the feedback back to product, and if they can code, possibly scope the change themselves. Nobody assigns that. It is just what the job is.

You should also expect things to go wrong more often. Pivots happen at this stage, and they are not abstract. The founders decide the product is aimed at the wrong customer and the company moves from B2C to B2B, and your work changes with it.

At Series B the job is narrower and the days are more predictable. It feels closer to a normal company, which is exactly what some people want. It is still a long way from consulting or corporate work, because you are scaling a product rather than servicing an account.

Which stage is best for learning?

Join early if you want to learn how a company gets built. Join later if you want to learn how one scales.

If you think you might start something yourself one day, the early stage is worth more than any course. You are sitting next to founders while they make the decisions, and you see which ones work.

That is not an argument that later stage teaches you less. Scaling is a genuinely hard skill and most companies fail at it. If you join at Series B the early chaos is over and you are learning how a company goes from working to big, which is the part most people never get to see.

Does a startup pay less, and does that change by stage?

At the earliest stages usually a little less, though less than people assume. By Series A it is normally a proper salary.

Early-stage founders keep their own salaries low on purpose, because every euro of payroll is a week of runway. That pressure reaches you too. But the size of the gap depends heavily on what you are comparing against.

A worked example. A seed-stage company in Belgium hiring a junior sales role offered a base about €200 a month below the consulting job the candidate was leaving. Slightly less on paper, market rate for the role, and with sales commission on top the total was higher. That is a very different picture from the one most startup content paints.

Where the pay cut is real is senior engineering compared against big tech. Nobody at a seed-stage company is matching what a FAANG or a frontier AI lab pays, and pretending otherwise would be dishonest. In go-to-market roles, in junior roles, and against consulting salaries, the gap is often small or absent.

By Series A you should expect a proper salary. Not big tech money, but comfortable, and no longer something you are compensating for with equity.

How much equity do you get, and how does that change by stage?

The earlier you join, the larger your slice, drawn from an option pool that is usually somewhere between 10 and 20 per cent of the company.

Companies set aside a pool of equity for employees when investors put money in. Everyone who is not a founder or an investor is paid out of that pool, and it gets topped up at later rounds.

One real data point rather than a benchmark table. An engineer at a YC company in San Francisco, employee number five or six, after a $3 million seed round: $100,000 salary and 0.4 per cent equity. That 0.4 looks small written down. If the company becomes genuinely large it is life-changing, and if it does not it is worth nothing.

What is worth copying is how he decided. He did not model the 0.4 per cent. He interviewed the founders, concluded they were the kind of team that would do whatever it took, and treated the equity as a bet on that judgement. Equity at seed stage is not compensation you can count. It is a position you take on people.

At Series B the numbers look different in both directions: a better salary, and a grant closer to a tenth of a per cent than half of one.

Is a founding title worth anything?

Yes, but what it is worth depends entirely on what the company did next.

Founding engineer on your CV tells a future employer that you joined something before it was safe, that you can operate without structure, and that you worked closely enough with a small team for it to matter. Those are real signals and they are hard to get any other way.

Be honest with yourself about the range though. Founding engineer at a company that scaled to Series C and founding engineer at a company that never found product-market fit are not read the same way. The second is still worth having. You learned things in the first eighteen months that people at bigger companies do not see for years. It just is not the same credential.

Why does a later stage mean lower risk?

Because at early stage the open question is whether the product works at all, and at later stage that question is already answered.

This is the whole rule in one sentence. A seed-stage company is still searching. A Series B company has customers, revenue and a repeatable way of finding more, and the job is to do more of it. Scaling can fail, but it fails more slowly and more visibly than the search for product-market fit does.

The risk is not abstract, and it is worth picturing concretely. You accept a job at a seed-stage company in another city. You move, you sign a lease, you rearrange your life around the decision. A month later the money runs out and the company closes. That is a real sequence of events and it is not one you meaningfully face at Series B.

Worth saying plainly: a founder who is about to run out of money is not flying candidates in and making offers. The risk is real, but it is rarely invisible.

What are the odds the company still exists in two years?

Nobody can give you a number by stage that you should actually trust. Assess the founders instead.

Survival statistics get quoted constantly and they are mostly useless to you. They lump together companies that raised nothing with companies that raised well, across every sector and country, and they tell you nothing about the specific company in front of you.

What you can do is look at the things that actually predict it. How recently did they raise, and how much. Whether there is revenue and whether it is growing. Whether the founders have built something before. Whether the people already there are staying. And, having spent a few hours with them, whether they strike you as people who will find a way through.

That last one sounds soft and it is the one people who have done this rate most highly.

What about a company that has not raised at all?

Then you are probably being offered a founding role rather than a job, and you should ask to see the numbers.

No money raised means no salary funded by investors, so what is on the table is usually equity, a founding title, or a position that turns into one. That is a legitimate deal and it is not the same decision as taking a job.

Ask for specifics and expect real answers. What is the revenue and what does the growth curve look like month over month. What is churn. How much is in the bank and how long can they pay you from it. Are they reinvesting everything they earn. Have the founders built something before.

Bootstrapped and profitable is a genuinely good situation. Bootstrapped with no product, no customers and no track record is a different one.

Browse by stage

You can filter startups by funding stage and city on the map and see what each one looks like.

Reading about stage only gets you so far. It is more useful to look at actual companies at each stage in a city you would move to, and see how they differ in size, sector and the roles they are hiring for.

Which stage suits which kind of person?

It comes down to how much uncertainty you can carry right now, not how ambitious you are.

If you are in your early twenties with no dependants, no mortgage and no notice period worth worrying about, seed stage is hard to beat. The downside is a year that did not work out, and you will have learned more in it than in three years somewhere safe.

If you have a mortgage and people relying on your income, the same advice is irresponsible. The failure mode is not that you learn less, it is that a company closing in month three is a genuine crisis rather than an inconvenience. Series A and later exist for exactly this, and choosing them is not a lack of ambition.

One path worth knowing about if you are coming from somewhere very structured, like big tech or consulting. Going straight to a five-person company is a large change all at once, and some people bounce off it. Joining at Series B first, spending a couple of years learning how the thing actually works, and moving earlier later is a real route. You might also find you like Series B and stay, which is a fine outcome.

One caution about stereotyping by stage. Culture varies enormously between companies at the same stage, and it varies most at seed, where it is simply whoever the founders are. The generalisation that holds is only that later stage feels more structured. Everything else you have to judge company by company.

What is the mistake people make when picking a stage?

Romanticising the early stage without understanding what the intensity is actually like.

People decide they want pre-seed or seed because it sounds like the real thing, and they are not wrong that it is. What they underestimate is the pace. Some of these companies run six-day weeks and very long days, and expect you to match, and there is rarely anyone above the founders to moderate it.

That is survivable and even enjoyable if you love the work and you like the people. It is miserable if either of those is missing, and at that intensity you find out quickly which one you have.

So ask directly what the working expectation is before you accept, and do not assume the answer is reasonable because nobody said otherwise. Ask what a normal week looks like, what time people leave, and whether weekends happen.

Go in with that clearly in view and the early stage is the best thing you can do for your career. It is not really a job. It is you joining a company and shaping it with the founders, and the people who enjoy it are the ones who wanted that rather than the ones who wanted a startup on their CV.
