AI-built app audit
Built it with AI? Let’s get it ready to grow.
Building a working product with AI tools is a real achievement, and it gets ideas in front of customers faster than ever. The next step is making sure it can grow with you: a solid structure underneath, safe data, sensible running costs and a market that wants it. That is where a second pair of experienced eyes helps.
The technologyHow the product is structured, how safe your data is, and what it will cost to run as you grow.
The businessWho it is for, how it stands out, and how it turns into revenue.
For founders who built with tools like Lovable, Bolt, Cursor, Replit or v0, and want to take it further.

My suggestion
Mentoring
Start with a few mentoring sessions. They will show what kind of technical leadership you need, if any. If you do, I can step in as a fractional CTO or help you hire.
Technical and commercial
Technology that pays off, not just technology that works.
Most technical advisors stop at the code. I have also owned revenue, retention and margin decisions with founders and boards, so my advice covers the business model too. The aim: more profit without adding cost, often by taking cost out.
Acquisition
The right customers, channels and message.
Retention
Why users leave, and what makes them stay.
Pricing
Packaging and prices that match the value you deliver.
Margin
Infrastructure, vendors and team time matched to revenue.
What you receive
Clear documentation, not just advice.
Every engagement ends with structured documents your team, board or investors can use. Yours to keep.
Audit reportsFindings ranked by business impact, with the cost to fix each one.
Architecture documentationHow your system works, written down and diagrammed.
Handover & knowledge transferRunbooks and notes, so no single person holds the keys.
Technology & product roadmapWhat to build, in what order, and why.
Board & investor reportsExecutive summaries that can be read in ten minutes.
Hiring kitsRole descriptions, interview plans and scorecards.
How it works
From first call to clear answer, in four steps.
- 01
Intro call
15 minutes on your situation. No preparation needed.
- 02
Tailored proposal
The right service, scope and price for your case.
- 03
Hands-on work
Audit, lead, advise or mentor. Always by me personally.
- 04
Documents & plan
Structured reports and a clear plan you keep.
Why an independent CTO
One senior person, fully on your problem. Nothing to sell you afterwards.
An agency brings a process built for many clients and a team it needs to keep busy. I bring fourteen years of CTO judgment, applied to your product, your plans and your numbers.
The person you meet does the work
No hand-off to a junior team. You speak to me on the intro call, and I am the one doing the work.
Agile, at your pace
I start quickly, without procurement layers or staffing plans, and move with your timeline.
No build agenda
No development team to keep busy, so no reason to recommend a rebuild. When you do need people, I help you hire the right ones.

About
Marios Prifti
- DeveloperWriting production software in Athens
- Engineering leaderBuilding teams across Europe
- CTO / CPTOTechnology and product, Europe · Dubai · US
- In the boardroomCo-owning business and investment decisions
I started as a software developer in Athens and moved through engineering leadership into C-level roles across Europe, Dubai and the United States, most often with technology and product under one remit.
I have built engineering organisations of more than thirty people across several countries, and hired and developed the engineering managers and CTOs who went on to lead them. I have also sat on the other side of the table: co-owning financial decisions with boards and investors, and directing technology spend as a driver of growth rather than a line item.
I build with AI every day; it makes good engineers faster. It does not replace the experience of designing and scaling systems that carry a real business.
