FAQ

How much does custom software development cost?

Cost depends on scope, complexity, and timeline. We work on both fixed-price projects and monthly retainers. Every engagement starts with a free discovery call where we scope the work together — you will have a clear estimate before any commitment is made.

What does a fractional CTO do?

A fractional CTO provides part-time senior technical leadership — setting engineering strategy, guiding architecture decisions, hiring and mentoring engineers, and representing technology at the leadership level. You get the same expertise as a full-time CTO at a fraction of the cost and commitment.

Do you work with clients outside Romania?

Yes — we work with clients across Europe and globally. All project communication is in English, and we are experienced with remote collaboration across different time zones. Most of our clients are outside Romania.
