Whatever the business' purpose and objectives, a CTO is primarily the owner of its Technology, whether software or hardware, and is the creator of its Technology Vision, and cheerleader of its technical talent.
As the most senior technologist, the CTO is the technology team's Leader, and is responsible for attracting, recruiting and retaining the top technical talent, and providing them with the best processes and infrastructure.
While their key focus is on technology, the CTO is primarily a Business Executive, and carries responsibility for the success of the business and its objectives alongside other heads of department.
The primary responsibility of the CTO at any stage of business is to translate business needs to technology strategy, and ensure that technology serves business best.
A CTO is responsible for more than just code - explore their duties and focuses below
"The CTO's primary job is to make sure the company's technology strategy serves its business strategy"
"First and foremost, a CTO must care about and understand the business, and have the ability to shape business strategy through the lens of technology. The CTO is an executive first, a technologist second."
"You cannot be a great CTO without building a great team. You can’t work wonders with a great team without a mission and a shared sense of purpose and an idea of how you will get there."
