What is a fractional CTO?
A fractional CTO is an experienced Chief Technology Officer who works with a company part-time, typically one to three days a week on a monthly retainer. They take full responsibility for technology strategy, architecture, engineering hiring and vendor decisions, without the cost of a full-time executive.
What does a fractional CTO do?
The work depends on your stage. For an early-stage company it is usually choosing the stack, scoping the MVP, hiring the first engineers and overseeing outsourced developers. For a growing company it is architecture, scaling, security, engineering process and representing technology to the board and investors.
How much does a fractional CTO cost?
In the US a fractional CTO working about two days a week typically costs $9,000 to $15,000 a month, according to Go Fractional marketplace data from October 2026. That is a fraction of a full-time CTO salary, benefits and equity. ibute starts with a fixed-price 2-week CTO assessment ($6,000 through Austin, TX or $3,500 through Lahore), then a monthly retainer of $6,000, $11,000 or $15,000 for 1, 2 or 3 days a week through Austin or $3,500, $6,500 or $9,000 through Lahore.
Is a fractional CTO from a company different from a freelance one?
A freelance fractional CTO gives you one person and advice. With ibute you get the same senior leadership plus a second CTO as backup and an engineering team that can build the roadmap if you want it. You are never left with a plan and no one to deliver it.
Who will be my fractional CTO?
Engagements are led by Irfan Malik, founder of ibute, who has 18+ years of experience including heading software engineering at Seamless, founding Synavos and serving as CTO of Iris Technologies. For clients who need deep platform or security leadership, our second fractional CTO, a specialist in Java, cloud architecture and data protection, leads instead. You meet your CTO before you sign.
How many hours a week does a fractional CTO work?
Typically one to three days a week, adjusted month to month. Early on, during the assessment and planning phase, it is usually more. Once direction is set and the team is running, it often reduces.
When should a company hire a full-time CTO instead?
When technology is the core of the business and the engineering team is large enough to need daily leadership, often after a significant funding round. Helping you define that role and hire the right person is part of a fractional CTO engagement.
Can a fractional CTO lead our AI strategy?
Yes. In 2026 most fractional CTO engagements include AI: deciding which AI features are worth building, choosing models and vendors, setting data and security guardrails and planning a build that survives production. Because ibute builds AI agents and LLM integrations every week, our fractional CTO advice on AI comes from shipped systems, not slides.
What is the difference between a fractional CTO and a virtual CTO?
The terms are mostly used interchangeably. Both describe a senior CTO who works part-time and often remotely. Fractional usually stresses the part-time commitment with real ownership of decisions, while virtual CTO is sometimes used for lighter, advisory-only arrangements. Our fractional CTO service takes ownership, not just advisory calls.
Do you work with companies outside the US?
Yes. We work with companies in the US, Sweden and across Europe. Our teams are in Austin, TX and Lahore, Pakistan, and we overlap with your working hours for meetings and stand-ups.
