What does a fractional CTO actually do?
A fractional CTO owns technical leadership for an agreed amount of time: strategy, architecture, support for the team and for hiring, oversight of suppliers, technical due diligence and the roadmap. The work runs on a monthly retainer. The same role is also called a part-time CTO.
Why a fractional CTO instead of a full-time hire?
You get a senior technology leader's experience straight away, without a long hiring process or the cost of a full-time executive. The model fits a stage where technical leadership is critical, but a full-time role would still be too large. When the company grows, I also help you hire a full-time CTO.
How is the work sized?
The number of days is agreed to fit the need, and it can be adjusted month by month. Busy phases, such as a launch, a funding round or a hiring push, can get more time.
How is the work priced?
The price is agreed after the first conversation, once the scope is clear. The options are a monthly retainer for an agreed number of days, a fixed-scope piece of work, or hourly billing. I invoice as a sole trader. Finnish VAT is 25.5%.
Who is this for?
A founder, CEO or product owner in a small or mid-sized company that has a product, a team or a supplier, and technical decisions that need an experienced owner. I work from Turku and remotely across Finland.
Do you also build software yourself?
Yes. I build fixed-scope pilots, MVPs, internal tools, integrations, and web and mobile apps. Building is agreed as its own project or as part of a monthly retainer.
What does AI change in development?
AI speeds up writing, trying alternatives and routine work a great deal. Quality still needs experienced judgment, review, tests and a clear specification. I use AI as an aid, and I am responsible for the result.
What does IoT planning cover?
The use case, the choice of devices and gateway, connectivity, the flow of data, the cloud and the software, and a plan for a pilot. If software is built after that, it is agreed as software development.
Who owns the results?
The contract transfers the results of the work to the client. Methods and knowledge I already had before the engagement stay with me. I can start under a non-disclosure agreement before I see code or figures.
How does the first conversation work?
It takes 30 minutes and it is free. We go through the situation, the goal and the decisions ahead, and you get a view of how to move forward. To book, call or email atso@tuohin.fi.
