Stop Making These 5 Mistakes When Building a Brand Design System

Funding is down, competition is up, and branding is no longer just a differentiator—it’s a survival tool. According to the latest CB Insights report, 2024 fintech funding is on track to hit its lowest level since 2017, meaning startups must compete harder than ever for attention, capital, and customers.

But here’s the thing—your brand doesn’t just happen. A strong brand isn’t the result of cool logos and clever slogans; it requires a system that keeps everything consistent, cohesive, and scalable. That’s where a brand design system come in—a playbook for your brand that ensures all assets (from your website to marketing) look and feel like one company, no matter how fast you grow.

But… most startups screw this up. They either go too big, too small, or make other costly mistakes that waste time, kill team morale, and destroy consistency. Here are the 5 most common mistakes—and how to avoid them.

1. Thinking Too Big

The Problem:

Some startups try to build the “perfect” design system from day one—anticipating every possible need. But instead of building a tool, they end up creating a monster: overly complex frameworks, unused components, and a system so big it collapses under its own weight.

Impact

Teams burn through budgets, miss deadlines, and launch nothing. The project grows out of control, people lose motivation, and you’re left with a half-finished design system that nobody uses.

Solution

Start small. Build a MVP that solves today’s needs. Add components as you grow—don’t guess at everything upfront. A design system is meant to evolve with your brand—not become an anchor that slows you down.

2. Thinking Too Small

The Problem

Some startups make the opposite mistake—they build a system so narrow it barely helps. They focus only on individual assets (like logos or fonts) without thinking through the bigger picture. The result? A design system that leaves too many gaps for teams to fill manually.

Impact

Your team ends up doing more work, not less. Designers scramble to create missing components on the fly, wasting time and causing inconsistencies. Instead of solving the problem, you create new ones—leading to frustration, delays, and wasted resources.

Solution

Build with balance. Focus on the core assets your team uses most—like buttons, typography, and colors—then leave room to grow. The goal isn’t to cover everything upfront, but to create a foundation that makes it easy to add more later.

3. Forgetting Who You’re Building For

The Problem

A brand design system isn’t just about pretty assets—it’s about creating seamless experiences for users. But too often, startups obsess over internal consistency and forget the real goal: building something users love.

Impact

Overly rigid systems kill creativity. When your design system becomes a set of rules rather than a tool, it limits what your team can do and frustrates users with uninspired, cookie-cutter experiences. In fintech—where trust and usability are everything—this can cost you customers.

Solution

Stay flexible. Your design system is there to serve your users, not trap your team. Build with scalability, but leave room for creativity. Incorporate user feedback and make it easy to adapt the system as your product evolves.

4. Not Involving Other Teams

The Problem

A brand design system impacts everyone—not just the design team. If you don’t involve marketing, engineering, and product teams early on, the system won’t meet their needs, and they won’t use it.

Impact on Startups

Teams resist change. When they feel left out, they go back to their old ways—creating their own assets, breaking consistency, and ignoring your system altogether. Adoption stalls, and the design system becomes a “nice idea” that nobody follows.

Solution

Collaborate from day one. Involve key stakeholders during the planning phase. Make sure the system solves problems for them and makes their jobs easier. When teams feel ownership, they’re more likely to embrace the change—and the system works.

5. Failing to Get Buy-In

The Problem

Brand design systems require time, money, and people—but without leadership buy-in, you’ll never get the resources you need. If leadership doesn’t see the value upfront, the project gets stuck in limbo.

Impact

Without buy-in, teams hesitate. Deadlines slip. Resources disappear. And instead of a powerful tool, you’re left with a half-built system collecting dust.

Solution

Make the case early. Show leadership how a design system saves time, reduces errors, and increases consistency. Tie the project directly to business outcomes—whether it’s scaling faster, improving the customer experience, or cutting marketing costs.

Build Smart, Not Perfect

A brand design system isn’t just “nice to have”—it’s essential for any startup that wants to grow. But the key is to build smart, not perfect. Avoid going too big or too small, and stay focused on creating better experiences for your users. Involve other teams early, secure leadership buy-in, and make sure your system evolves with your business.

Getting your branding right can mean the difference between standing out or getting left behind. Startups that invest design systems work faster, create (and test) more features, stand out—and win. The ones that don’t get stuck fixing problems they could have avoided.
