From Developer to CTO: Why Your Best Coder Might Not Be Your Best Leader

You've got an amazing developer who can write code like magic. They built your entire product from scratch, know every line of code by heart, and can fix any bug in minutes. Naturally, when it's time to grow your team, you think "Let's make them the CTO!"

Hold up. This is one of the biggest mistakes tech companies make.

Here's the thing – being great at coding and being great at leading people are completely different skills. It's like assuming your best chef would automatically be a great restaurant manager. Sure, they know food inside and out, but managing staff, dealing with suppliers, and handling customer complaints? That's a whole different game.

The protective parent problem

When developers become CTOs without proper management training, they often turn into overprotective parents of their code. They've built this thing from the ground up, and now they can't let go. They become the bottleneck for every decision because "nobody else understands it like I do."

This leads to several problems:

They struggle to delegate. Why let someone else write a feature when they could do it "properly" themselves? The problem is, as a CTO, their job isn't to write all the code anymore – it's to help other people write good code.

They lose patience quickly. When a new developer asks questions about something that seems "obvious" to the CTO, frustration builds. What takes the CTO 10 minutes might take a new team member 2 hours, and that's perfectly normal! But without management training, this feels like wasted time instead of necessary learning.

Communication becomes a nightmare. Great developers often communicate in technical jargon and assume everyone thinks like they do. When team members don't understand, the developer-turned-CTO gets frustrated instead of finding better ways to explain things.

The turnover tornado begins. All of these issues create a toxic environment that sends good developers running for the exits. I've seen companies with 90% developer turnover in a single year because of this exact problem. New hires quickly realize they'll never be trusted with important work, their questions aren't welcome, and they're constantly being second-guessed. So they leave, often within just a few months.

The equity trap

Here's another nightmare scenario: If your technical co-founder has significant equity and turns out to be a poor manager, removing them becomes incredibly complicated. Unlike firing a regular employee, you're dealing with an owner of the company. This creates legal headaches, bad blood, and can even threaten the company's future.

I've worked with startups racing against time to remove technical co-founders before their equity fully vests. It's messy, expensive, and distracts from actually building the business.

What makes a good CTO?

A great CTO needs to be part technologist, part people manager, and part business strategist. Here's what to look for:

Communication skills: Can they explain complex technical concepts to non-technical team members? Can they listen to concerns and provide helpful feedback?

Management experience: Have they successfully led teams before? Do they understand how to motivate people and create productive work environments?

Strategic thinking: Can they make technology decisions that support business goals, not just technical perfection?

Patience and teaching ability: Are they willing to invest time in helping others grow, even when it would be faster to do things themselves?

The solution

If you have a brilliant developer who wants to move into leadership, don't just hand them the CTO title and hope for the best. Instead:

1. Start small: Give them a small team to manage while keeping their technical responsibilities

2. Invest in training: Management training isn't optional – it's essential

3. Find a mentor: Connect them with experienced CTOs who can guide them through the transition

4. Be honest about expectations: Make it clear that success will be measured by team performance, not just technical output

Remember, your best developer might become a great CTO with the right support and training. But assuming they'll naturally excel at management without help is setting everyone up for failure.

The goal isn't to discourage technical people from becoming leaders – it's to make sure they have the tools they need to succeed in that new role.
