Hiring a CTO is one of the most important decisions a startup founder can make.
But at an early-stage startup, your best CTO might be someone you grow inside the company.
Here's why.
How Zepto Got Its CTO
Let’s take a classic example
Look at Zepto.
You'd think a startup growing that fast would hire a superstar CTO from Amazon or Google. Someone with a fancy title and years of experience.
They didn't.
Nikhil Mittal was one of Zepto's earliest employees. He joined early, helped build its technology and engineering organisation, took on larger responsibilities, and eventually became CTO.
He wasn't hired as CTO. He grew into the role.
And that's an interesting playbook for early-stage startups.
Why You Shouldn't Hire an External CTO
They don't know your product's scar tissue.
Early products are full of decisions made under pressure. Some technical debt exists simply because shipping was more important than perfection. Someone who built alongside you understands why those decisions were made.
Titles don't build teams. Trust does.
The engineer who has been through outages, pivots, failed releases, and impossible deadlines has already built credibility with the team. An external CTO has to earn that trust from scratch.
The CTO role keeps changing.
In the beginning, it might mean writing code every day. Later, it means hiring engineers, building processes, managing leaders, and making long-term technology decisions.
Someone who grows with the company understands the product, technology, people, and history behind those decisions.
