Over the years, I’ve accompanied many startups and also built several myself – as a freelancer, as a consultant, and as a founder who built a team from scratch. And I see the same mistakes over and over again. Not from bad founders. But from ambitious ones who are simply moving too fast. Or making decisions under pressure. Or both.
Here are the eight most expensive hiring mistakes of the early stage and what you can concretely do about them:
Mistake #1: You hire for today, not for tomorrow
The most common mistake of all: you fill a position for the current pain without thinking about what the person needs to be able to do in twelve or eighteen months. A junior who processes to-dos today might be the bottleneck in your team in a year. Not because they’re bad, but because your startup has grown faster than they have.
What you should do: Before you post a position, ask yourself a question: What should this person be responsible for in 18 months? Not accomplish – be responsible for. The difference is crucial. Hire for the role you’ll need, not for the one you have today.
Mistake #2: You evaluate skills, not mindset
This is the mistake that costs the most and is hardest to see. A strong CV, good references, a convincing interview – and yet it doesn’t work in the team. Because skills are measurable, but mindset isn’t on paper.
What I mean: someone can be excellent at performance marketing and at the same time unable to work in a startup with little structure, lots of responsibility, and constantly shifting priorities. That’s not failure, that’s a mismatch. And recognizing that is your job as a founder.
What you should do: In the interview, don’t just ask what someone has done, but how. Ask about situations where things went wrong. Ask how someone deals with ambiguity. Anyone who can only work in clear structures won’t be happy in your startup. And unhappy employees cost you more than an open position.
Mistake #3: You ignore cultural fit until it’s too late
Startups talk a lot about culture. And often act contrary to it when the pressure rises. The position has been open for three months, the team is overwhelmed, the next candidate is “good enough,” so they get hired. And two quarters later you wonder why the mood has shifted.
Cultural fit is not a nice-to-have. It determines whether your team sticks together or falls apart during stressful phases. This applies to full-time employees just as much as to external experts you temporarily bring into the team.
What you should do: Define three to five values or behaviors that are non-negotiable in your team before you hire next time. Not as a poster on the wall, but as a concrete picture: what does that look like in everyday work? Who fits in, who doesn’t? And then stick to it. Even when you’re under pressure. And explicitly build a culture check as a single component in your hiring process.
Mistake #4: You buy a title and don’t get what you expected
This is one of the biggest misconceptions of all and it happens especially often in sales. You’re looking for someone to do sales. So you look for a Head of Sales or Director of Sales with an impressive CV. Big companies, well-known names, probably a strong network.
The problem: many people at this level haven’t actually sold anything in years. They’ve managed, reported, developed strategies, led teams. Those are valuable skills, but not the ones you need in the early stage. You need someone who picks up the phone, does cold outreach, improvises in conversations, and still writes a follow-up email in the evening. That’s a different person than someone who builds dashboards and presents quarterly targets.
The network they bring – the much-cited “door opener” – often turns out to be another misunderstanding. Contacts from a previous role at an established company rarely transfer simply to a new context. Someone who previously worked as Head of Sales at a DAX company or late-stage scaleup doesn’t automatically have contact with the decision-makers relevant to your startup.
What you should do: Clearly separate two roles: the seller and the sales leader. In the early stage, you almost always need the former. Ask very specifically in the interview: when was the last time you personally brought a deal from zero to close? What did your last prospecting day look like? Who are three contacts in your network you’d call tomorrow and why would they pick up? The answers tell you more than any title on the CV.
Bastian Deurer’s career path led him from strategy consulting at IBM and PwC through executive positions at ProSiebenSat.1 and Payback to management roles in an agency and into self-employment, where he worked for years as a freelancer in digital projects. Precisely from this experience, he founded Dygitized: to bring companies together with the right digital experts – not just technically, but also personally. Quickly, customized, and with genuine understanding for operational realities.
Mistake #5: You build a team of B-players because A-players scare you
This is a pattern I see again and again and hardly anyone talks about openly. Founders who unconsciously prefer candidates who don’t shine too brightly. Who don’t ask uncomfortable questions. Who aren’t better than you in certain areas. The result: a team that’s nice to each other, but doesn’t challenge anyone. A team that functions, but doesn’t win.
A-players are uncomfortable. They question decisions. They have their own opinions. They want to grow and get impatient when they can’t. But that’s exactly what your startup needs in the early stage. People who are better than you in their area and who force you to get better too.
The rule applies here as nowhere else: A-players hire A-players. B-players hire C-players. If you make the wrong decision now, it ripples through your entire company culture – often for years.
What you should do: Be honest with yourself. Are you rejecting someone because they really don’t fit or because they challenge you? Both are valid feelings, but only one is a good reason. Hire people who are better than you in their field. That’s not a weakness. That’s good entrepreneurship.
Mistake #6: You invest nothing in onboarding
You spent three months finding the right person. The first two weeks you figure out what they should actually do. No structured onboarding, no clear scope, no buddy in the team. The person is motivated but disoriented. After 90 days you wonder if the hiring was wrong after all. Usually it wasn’t. The onboarding was.
I’ve started jobs and projects as a freelancer and as an employee where I didn’t know who to ask in the first week, which tools to use, or what success meant. That costs energy on both sides and trust that you can’t waste in the early stage.
What you should do: Define the first 30 days for every new person – whether full-time employee or external expert. What should they understand? Who should they meet? What should they be able to do independently by the end of the first month? A simple 30-60-90 day document is enough. It forces you to think clearly. And it shows the person that you take them seriously.
Mistake #7: The process only exists in your head – nowhere else
In the early stage, much runs through the founder. That’s normal. It becomes a problem as soon as new people join the company and nobody can explain to them how work actually gets done here.
How are decisions made? Where are things? Who is responsible for what? How does a project run, from idea to implementation? If the answer to all these questions is “only I know that,” then you don’t have a team. You have dependency.
Every new person who joins needs orientation. Not because they’re incompetent, but because they don’t know your company. If processes, structures, and decision logic only exist in the founder’s head, you lose valuable time with every onboarding. And you make your company unnecessarily fragile, because the bus you could fall under always comes closer than you think.
What you should do: Start small. Document the five most important workflows in your company: how you work, how decisions are made, which tools you use and why, who carries what responsibility. Just a living, accessible foundation that puts every new person in a position to become independent quickly. That’s also a sign of company maturity.
Mistake #8: A good conversation is not a multi-stage hiring process
This is the mistake that comes dressed most elegantly. “We had a good conversation. I just feel it.” Maybe. But a good conversation is not a hiring process.
A 45-minute get-to-know tells you whether someone is likeable and sells themselves well. It tells you little about how someone works under pressure, how they handle conflict, how they prioritize when everything is burning at once. You don’t learn these things in the first conversation. You learn them in a case study. In a second interview with concrete scenarios. In a conversation with future teammates. In a reference check that you actually do and don’t just have on your to-do list.
Good hiring decisions are multi-stage, not because HR wants it that way, but because people are more complex than a first contact suggests. And because a misplaced hire in the early stage is simply too expensive – financially, time-wise, and culturally – to leave to chance.
What you should do: Set at least three touchpoints for each role before you make a decision. First conversation to get to know each other. A practical task or case study. A follow-up conversation with a second person from your team and one more culture check. That costs another week. It saves you six months of pain if needed.
The bottom line
Bad hiring in the early stage is not bad luck. It’s usually the result of too little clarity, too much pressure, and too little structure in the process. The good news: all eight mistakes are avoidable if you take the time before you start looking.
Who am I? What do I really need? Who do I want to sit next to me when things get difficult? And how do I make sure this process doesn’t just exist in my head? Those are the questions that matter. Take the time to answer exactly these.
