Introduction: IT is the Backbone. Don’t Let It Break You Early

Starting a company is hard. There’s pressure from every side — building a product, finding customers, managing cash flow. In all this, IT often gets treated like a side task. Something to “figure out later.” That mindset is risky.

We’ve worked with good numbers of European startups, and we’ve seen the same IT problems come up again and again. Some look small at first but grow into expensive headaches. The good news? Most of these mistakes are easy to avoid if you know what to look out for.

Let’s walk through the five most common IT mistakes startups make and how you can stay clear of them.

Mistake #1 – Starting Without a Scalable Tech Foundation

When you're in MVP mode, it’s tempting to go with whatever’s fast and cheap — shared hosting, free plugins, a patched-together tech stack. It works for now, so why worry?

But your early tech decisions have a long tail. A shaky foundation slows you down later. As you grow, performance dips, bugs pile up, and adding new features becomes a pain. Worst of all, fixing the mess can cost more than building it right from the start.

How to avoid it:
Pick tools and platforms that can grow with you. Use cloud services that let you scale up when needed. Choose frameworks your future developers will actually want to work with. Keep things lean, but don’t cut corners.

Qtech Tip:
Before choosing any tech, ask yourself: “Will this still work when we have 1,000 users?” If not, rethink.

Mistake #2 – Ignoring Basic Cybersecurity Practices

Many startups ignore cybersecurity until something goes wrong. A leaked password, a hacked site, or a lost laptop can trigger chaos and damage your brand.

If you’re handling user data, even in small amounts, you have a legal and ethical duty to protect it. In the EU, GDPR applies from day one even if you're just a team of two.

How to avoid it:

Start with simple habits:

• Use strong, unique passwords (use a password manager).
• Turn on two-factor authentication.
• Keep your software up to date.
• Run backups regularly.
• Use HTTPS, always.

Qtech Tip:
Security doesn’t have to be expensive. But ignoring it will be.

Mistake #3 – Underestimating Technical Documentation

When you’re moving fast, it’s easy to leave everything in people’s heads or scattered across Slack, email, and Notion. The thinking is: “We’ll clean it up later.” But later never comes and then your lead dev leaves.

Without proper documentation, your team wastes hours figuring out how things work. Onboarding slows down. Fixing bugs takes longer. And knowledge walks out the door with every departure.

How to avoid it:
Document key parts of your tech stack. This doesn’t mean writing a book. A simple, well-organized internal wiki is enough. Focus on APIs, infrastructure, workflows, and critical systems.

Qtech Tip:
Create templates for documenting code, tools, and internal processes. Good documentation pays off every time you grow.

Mistake #4 – Not Aligning IT With Business Goals

Startups often build tools or features just because they “seem cool” - not because they solve real problems. This happens when the tech team and the business side aren’t aligned.

We’ve seen startups where the dev team builds a dashboard the sales team never uses, or adds features that no one asked for. That’s wasted time and money.

How to avoid it:
Make sure every IT decision supports a clear business goal. Talk regularly across teams. Sync product roadmaps with marketing and sales. Keep the focus on value, not just code.

Qtech Tip:
Hold monthly strategy sessions with founders, developers, and marketers. Ask: “Does this help us grow?” If not, pause.

Mistake #5 – Outsourcing Without Oversight

Hiring freelance developers or agencies is common and often smart. But it can go very wrong if you’re not clear about what you want. Vague briefs, poor follow-up, and no accountability lead to delays and rework.

You might save money up front, but you’ll lose more fixing problems later. And your product might end up full of hidden issues you don’t catch until it’s too late.

How to avoid it:
Be clear with expectations. Share your goals, not just tasks. Use written specs. Break work into sprints with regular check-ins. Choose partners who understand both tech and business.

Qtech Tip:
You don’t just need someone who can code. You need someone who understands your product and your market.
