Fractional CTO Services in Warsaw
The best Fractional CTO Services in Warsaw, at the best available price.
You have engineers, or contractors, or an agency, and no one whose job is to decide whether the architecture, the spend and the hiring plan are right. That is the gap: ten to twenty hours a month from someone who has built and run the thing you are building, and who will tell you when you are about to spend money you do not need to.
Warsaw is Poland's financial and corporate centre, with the Warsaw Stock Exchange, major Polish banks, a dense cluster of shared service and technology centres, and well-known game studios. Poland has a deep pool of strong engineers, so Warsaw buyers mostly look for specific skills, such as private AI deployment, that their teams have not built yet.
Warsaw startups often scale engineering quickly from a strong local talent pool. A fractional CTO keeps architecture, cloud spend and hiring decisions coherent through that growth.
What you get
- Architecture decisions made and written down, with the trade-offs stated rather than assumed
- Infrastructure and AI spend reviewed against what you actually use, not what you provisioned
- Hiring: what roles you need next, what to test for, and which hires to delay
- A technical voice in investor and customer conversations when you need one
- Honest counsel on build versus buy, including when the answer is to buy
Scoped to the hours you actually need. Month to month, with no long lock-in, because a fractional CTO you cannot leave is just an expensive employee.
Invoiced in USD or EUR, payable by Wise or bank transfer.

Who builds here
On-Premise LLM Deployment
Warsaw's banks, insurers and their technology centres already have strong engineers, but serving a model reliably on their own hardware under KNF and DORA expectations is specialist work. That gap is exactly what the private LLM engagement fills.
What Warsaw companies build with us
Get it built at $0.
That is not a discount. It is when you pay. The work is split into checkpoints with acceptance criteria written down before anything starts, and each checkpoint is invoiced only after you have seen it and accepted it. No deposit.
- $0 to start
- You hold every dollar until a checkpoint is delivered and you accept it. No approval, no invoice.
- Fixed cost, unlimited features
- Or hire the team outright: one fixed monthly cost, unlimited feature development, any stack.
- The engineer takes your call
- The person on your first call is the one who architects and writes it. No account managers, no bench time.
A US agency quotes $50,000 to $150,000 for the same build and asks for 40 to 50% of it before a line is written. Account managers, project managers, sales commission and bench time. None of it appears in your product.
Three stages, nothing hidden.
Twenty-minute call
We work out whether you need a fractional CTO at all. Plenty of teams need one good senior engineer instead, and that is a cheaper answer worth hearing.
First month, diagnostic
Architecture, infrastructure spend, delivery process and team shape reviewed, with the findings written down plainly and prioritised by what they cost you.
Ongoing retainer
A fixed block of hours each month. Regular reviews, decisions when they are needed, and direct access rather than a ticket queue.
What actually applies here.
Regulation and data
GDPR is enforced by UODO (Urząd Ochrony Danych Osobowych). Poland's banks and insurers answer to the KNF, whose guidance on cloud outsourcing sits alongside DORA, in force for financial entities since January 2025. Poland transposed NIS2 through an amendment to the Act on the National Cybersecurity System, signed in February 2026. Its Act on Artificial Intelligence Systems entered into force on 27 July 2026, creating a new supervisor, the Commission for the Development and Security of Artificial Intelligence (KRiBSI), with some provisions applying from late October 2026. EU AI Act transparency duties apply from August 2026 and most high-risk obligations from December 2027.
Contracting and payment
You contract with an individual consultant based in India. Invoices in EUR or USD, paid by Wise or bank transfer. Your accountant handles an overseas supplier in the usual way, and any documentation they need is provided before access is granted.
Working hours
Four or more hours of daily overlap across your morning, Central European time, with same-day replies on working days.
Why use you when Warsaw has so many good engineers?
Often you should hire locally. Where we help is specialist work your team has not done before, such as serving a model on your own GPUs or building an AI analyst with strict access controls, done once properly and handed over with documentation.
Can you meet KNF and DORA expectations?
We build to your outsourcing and ICT risk requirements: named limited-privilege access, infrastructure in your own accounts, audit logs and an exit plan with all access removed at handover. Your compliance team keeps the regulatory assessment, and we supply what it needs.
Do we actually need a fractional CTO?
Often not, and you will be told so. If the real problem is that nobody is building fast enough, a senior engineer is a better spend. A fractional CTO earns its cost when the expensive decisions are the bottleneck: architecture, infrastructure spend, build versus buy, and who to hire next.
How is this different from an advisor?
An advisor gives opinions. This role makes decisions, writes them down, and is accountable for them. Where it helps, the work is done rather than delegated, including the parts that involve opening the codebase.
What happens to our existing team?
They keep building. The role is to remove the decisions that block them and to be honest with you about where the team is short, which is usually a smaller gap than founders fear.
