I grew up in Istanbul, where every corner shop has a hand-painted sign that somehow feels more alive than half the startup websites I review on a given week. There's something in that. Brand isn't about looking expensive or polished or following the current design trends on Twitter. It's about looking like you mean it.

I've been working with startups long enough now to have seen the same mistakes made by very different people — technical founders, creative founders, first-timers and repeat entrepreneurs. Smart people, good products, genuine intentions. And still.

Here are the five I keep seeing.

1. They think the logo is the brand.

This is the most common one, and I understand where it comes from. The logo is concrete, it's deliverable, it's the thing you can point at and say "that's us." But it's the smallest part of the system.

The brand is how your product makes people feel before they've read a single feature. It's the tone of your first email to a new user. It's whether your error messages sound like a human wrote them or a legal team approved them. It's the three words someone would use to describe your company to a colleague over coffee. I spend maybe 20% of a branding project on the logo itself. The rest is everything around it.

2. They copy whoever just raised a big round.

It makes sense as a strategy, in theory. If that company looks credible, and we look like that company, we'll look credible. The problem is timing. By the time you've noticed their aesthetic, analyzed it, briefed an agency or freelancer, gone through rounds of feedback, and launched — it's already moved on. Your competitors are doing the same thing, and now you all look the same.

The other problem is that it communicates nothing specific about you. You're not that company. Your story is different, your positioning is different, your customers might be completely different. A brand that doesn't say anything specific about you is just visual noise.

3. They don't decide who they're not for.

This is the hard one. When you're early and trying to grow, the instinct is to be for everyone. Don't say anything that might put someone off. Stay broad, stay safe.

But the clearest brands make someone feel excluded. That's not a bug — that's the signal. It tells the right people: this was made for you specifically. Apple's early advertising excluded people who didn't think of themselves as creative. Monzo's early brand excluded people who wanted a bank that felt like a bank. The exclusion is what creates belonging.

4. They skip the naming conversation.

Your name is working 24 hours a day, seven days a week. It's doing SEO work every time someone searches for your category. It's doing first-impression work every time someone hears it. It's doing word-of-mouth work every time someone tries to recommend you to a friend.

"We'll figure out the name later" is something I've heard many times, and it always costs more later — not just in rebranding fees, but in lost credibility and confused positioning. The name is part of the brand. It deserves the same attention.

5. They design for the pitch deck, not the product.

There's a specific aesthetic that investors respond to in pitch decks. Clean, confident, slightly austere. And founders, naturally, want their brand to feel the same way — because the goal is to raise money, and this is what raises money.

The problem is that pitch deck aesthetics and product aesthetics serve completely different purposes. One is trying to impress a small number of sophisticated people for fifteen minutes. The other is trying to earn trust from a large number of people who are slightly skeptical and have thirty seconds.

I've seen founders end up with a brand that looked great in a deck and confused actual users. Build the brand for the people who will use the product. The deck can adapt to that. The product can't adapt to the deck.
