How to hire a designer for your startup (And the #1 trait most startups overlook)

When hiring a designer for your startup, what’s the first thing you look at?

Their portfolio? Years of experience? Famous clients?

After interviewing 36 hiring managers at AI and tech startups, one surprising answer came up again and again:

Trust beats talent.

In this guide, we’ll break down why trust is the #1 trait to look for when hiring a designer and how to assess it early in the hiring process so you avoid wasted time and missed deadlines.

Why trust matters more than design skills

Startups move fast. You need designers who not only deliver quality work but do so reliably, consistently, and without drama.

Here’s what startup leaders told us:

I know my designer isn’t the best… but I trust him.
— Startup founder
If I’m constantly chasing updates, it’s a no from me.
— Head of Growth
Anyone can make things look good. I’m looking for someone who makes my life easier.
— Chief Marketing Officer

Why is trust such a big deal?

A stellar portfolio means nothing if they ghost mid project.

  • Big name clients won’t help if they can’t hit your deadlines

  • Even great visual skills fall flat if they don’t communicate well

Startups need design partners they can count on, not just pretty pixels.

7 ways to assess a designer’s reliability (before you hire them)

1. Evaluate communication from day one

Responsive, clear, and proactive communication is a strong predictor of reliability

What to look for:

  • Prompt, thoughtful responses

  • Clarifying questions that show understanding

  • Initiative in sharing updates

Red flags:

  • Vague replies or ghosting

  • Delayed or inconsistent communication

Test idea: Send a simple request and see how fast and clearly they reply

2. Look for consistency in their portfolio

Don't just judge the highlights, look at the full picture

What to look for:

  • Steady quality across projects

  • Real world outcomes (not just visual polish)

  • Design rationale explained clearly

Red flags:

  • Major quality gaps across projects

  • Portfolio full of personal or speculative work only

Test idea: Ask them to walk you through a project and explain the business impact

3. Verify availability and workload

A common cause of failure is overpromising. Vet their schedule

What to look for:

  • Clear, honest answers about current workload

  • Timeline transparency from the start

Red flags:

  • Says yes without checking availability

  • Commits to tight deadlines too quickly

Test idea: Ask follow up questions before hiring to gauge their bandwidth

4. Assess their problem solving mindset

The best designers don’t just execute, they think

What to look for:

  • Asks why before executing

  • Offers strategic input, not just designs

  • Connects visual work to user and business goals

Red flags:

  • Blindly follows directions

  • Struggles with ambiguous challenges

Test idea: Ask “How would you improve signups on this landing page?”

5. Check for repeat clients and referrals

Client loyalty signals a good working relationship and trust

What to look for:

  • Long term or repeat clients

  • Testimonials or references

  • Measurable impact over time

Red flags:

  • Only one time projects

  • No client feedback or referrals

Test idea: Ask “Can you share an example of a client you worked with more than once?”

6. Observe how they handle feedback

Design is iterative. How they receive and act on feedback matters

What to look for:

  • Open to input

  • Clarifies before changing

  • Improves without ego

Red flags:

  • Gets defensive

  • Ignores or misinterprets feedback

  • Blindly applies changes

Test idea: Offer minor feedback in the interview and observe their reaction

7. Start with a low risk test project

Before a big commitment, test them under real conditions

What to look for:

  • Consistent quality

  • Timely delivery

  • Proactive communication

Red flags:

  • Missed deadlines

  • Communication breakdowns

  • Rushed or low effort output

Tip: A 3 day test project is usually enough to spot future problems

Bonus tip: trust your intuition

Your gut often processes red flags before your brain does. If something feels off, it probably is

You’re not just hiring a designer. You’re hiring a collaborator. And collaboration requires trust
