Need clarity?
CTO Review
A focused investigation that gives you an independent senior CTO view of what is actually happening and what should happen next.
Technology under control.Business moving forward.
Clarity for difficult technology decisions.
Leadership when execution needs fixing.
How we work together
Need ownership?
Fractional CTO
Ongoing senior technology leadership when the organisation needs someone to take ownership now and deliver results.
I usually get involved when…
- 01
Engineering isn't delivering.
Deadlines keep moving, quality is suffering or nobody can clearly explain why progress is so difficult.
- 02
You don't know whether to trust the technical advice you're getting.
Your internal team, agency or vendor has an answer — but you cannot independently tell whether it is the right one.
- 03
A big technology decision is approaching.
Build or buy. Rewrite or improve. Migrate or stay. Invest, change direction or stop.
- 04
You’re considering investing in or acquiring a software company.
You need an independent view of whether its technology, team and delivery capability can support the plan.
- 05
The product is growing faster than the technology around it.
Reliability, scalability, cloud cost, technical debt or operating complexity are becoming business problems.
- 06
You have something worth building, but not yet the technical organisation to build it.
A new venture, product idea, prototype or AI-built tool now needs realistic scope, architecture, team, cost and execution.
- 07
You need experienced technology leadership, but not necessarily another permanent executive.
A CTO has left, leadership is missing, an existing technology leader needs reinforcement, or an important initiative needs senior ownership.
Need clarity? / CTO Review
You probably need a CTO Review if…
- Your developers keep missing deadlines and you no longer know whether the estimates are reasonable.
- Your agency or engineering team says everything is complicated, but you cannot independently tell whether that is true.
- Someone is proposing a rewrite, migration or major rebuild and you are about to commit serious money to it.
- Engineering costs keep growing, but it is not obvious what the business is getting for the money.
- The product works today, but you are worried the technology will not survive the next stage of growth.
- Your CTO or technical lead has left and you need to understand what state the technology and team are actually in.
- You have a product, prototype or AI-built tool and need to know what it will really take to turn it into a reliable business.
- You are being asked to approve a major technical investment and want an independent opinion before saying yes.
- You’re an investor, board member or acquirer evaluating a software business and need technical due diligence focused on the risks that actually matter to the investment.
Outcome
An independent view of what is actually happening, the important risks and decisions surfaced, clear recommendations, and a prioritised plan for what happens next.
The investigation adapts to the actual problem across technology, delivery, people, architecture, cost, risk and business context. It is not a generic checklist audit. For investors and acquirers, the review can be delivered as an investment-focused technical due diligence assessment, covering technology risk, engineering capability, roadmap credibility and likely future investment.
A review may lead to Fractional CTO work, but it does not have to.
Need ownership? / Fractional CTO
Senior technical ownership, at the level the business needs.
- You need an experienced technology leader, but a permanent executive hire is not the right move yet.
- A CTO or technical lead has left and the business needs clear senior ownership while it decides what comes next.
- An existing technology leader or engineering team needs experienced reinforcement to move an important initiative forward.
- Technology decisions, delivery risk or architecture are becoming business-critical and need someone accountable for the outcome.
- The product is growing and the connection between business priorities and engineering execution needs stronger leadership.
- Vendors, partners or a distributed team need senior technical direction and a clear point of ownership.
Outcome
Clear senior technical ownership, stronger execution and sustained progress without immediately committing to a permanent CTO hire.
I step into your business and connect its priorities with execution. The engagement is defined by leadership, responsibility and outcomes — not a monthly allocation of consulting hours.

Artur Wiśniewski
Fractional CTO / Technology Leader
For more than a decade, I’ve led technology across people, product and engineering — helping complex products evolve through pivots, growth and years of production use. I operate as a technology leader while staying close enough to the work to challenge assumptions and collaborate directly with engineers.
I make complicated technology understandable to non-technical decision-makers. My approach is commercially pragmatic: clarify the trade-offs, make the decision the business needs and account for its long-term consequences.
01
Technology leadershipMore than a decade operating as a CTO.
02
People, product and technologyLeadership across teams, delivery and architecture.
03

04
Commercial judgementReliability, risk and cost matched to business value.
Let’s bring clarity to your technology decisions.
A short conversation can save months of uncertainty.
