How to Evaluate a Software Contractor Before You Hire

Most founders evaluate contractors on technical skills they can't assess. Here's what actually predicts whether a developer will deliver what your startup needs.

As a non-technical founder, hiring developers is one of the most stressful decisions you'll make. You can't evaluate their code. You don't know if their estimates are realistic. And you've probably already been burned by at least one contractor who seemed great in the interview.

Here's what I've learned from working with dozens of non-technical founders who struggled with this exact problem.

The Real Problem Isn't Technical Skills

Most founders make the same mistake: they try to evaluate contractors on technical skills they don't understand. They ask for portfolios, check GitHub profiles, and maybe get a technical friend to review their work.

But here's the thing: technical skills are table stakes. Any decent contractor can build what you need. The real question is whether they'll build what you actually need.

The contractors who fail aren't usually bad at coding. They're bad at:

  • Understanding your business context
  • Asking the right questions before building
  • Communicating when things go wrong
  • Pushing back when your requirements don't make sense

Good Contractor vs Bad Contractor

What to Look for Instead

1. How They Handle Ambiguity

Give them an intentionally vague requirement: "We need a dashboard for our sales team."

A good contractor will ask clarifying questions:

  • Who uses this dashboard?
  • What decisions do they make with it?
  • What data do you already have?
  • What does success look like?

A bad contractor will immediately start talking about technologies, frameworks, and timelines.

2. Their Communication Style

Before you sign anything, have at least 3 calls with them. Pay attention to:

  • Do they explain things in terms you understand?
  • Do they admit when they don't know something?
  • Do they follow up in writing after calls?
  • How long does it take them to respond to messages?
Communication Is a Leading Indicator

The contractor who takes 3 days to respond to your email will take 3 days to tell you about a critical bug in production.

3. How They Handle Disagreement

Intentionally suggest a bad idea. See how they respond.

A contractor who just agrees with everything is dangerous. They'll build exactly what you asked for, even when what you asked for is wrong.

The best contractors I've worked with have all pushed back on my ideas at some point. They've said "I don't think that's the best approach, here's why..." and then explained their reasoning in terms I could understand.

Red Flags to Watch For

Red Flags to Watch For
  • They promise unrealistic timelines
  • They never ask questions about your business
  • They get defensive when you ask about their process
  • They want to rewrite everything from scratch
  • They can't explain their work in simple terms

The Best Contractors Think Like Partners

The contractors who succeed with non-technical founders don't think of themselves as "code writers." They think of themselves as problem solvers who happen to use code.

They're invested in your success. They'll tell you when an idea is bad. They'll suggest simpler solutions. They'll flag risks before they become emergencies.

These contractors are rare. When you find one, pay them well and treat them like a partner.

Starting Small

Don't commit to a big project upfront. Start with a small, well-defined task that you can complete in 2-3 weeks. This gives you a chance to evaluate their communication, their work quality, and how well they understand your business.

3Expand the engagement

If the small project goes well, you can expand the engagement. If it doesn't, you've only lost a few weeks instead of a few months.


Finding the right technical partner is hard. But it's not impossible. Focus on communication, business understanding, and their willingness to push back. The technical skills will follow.
