We can, but the roles stay separate: leadership advises and reviews independently of any delivery team, including ours.

How quickly can you start?

Discovery normally begins within one to two weeks of a signed proposal, and we can run a paid discovery sprint immediately if timelines are tight.

Who owns the code and accounts?

You do — source code, cloud accounts, repositories, and analytics are yours from day one and handed over in full at any point.

Can you work alongside our in-house team?

Yes. We embed with internal teams, follow their conventions and review process, and document everything for clean handover.

Overview

What CTO as a Service means at XentraSol

Plenty of companies need CTO-level judgement long before they can justify a CTO salary. Fractional leadership gives you architecture decisions, hiring standards, and board-level technical reporting on a defined monthly commitment.

Typical engagements cover strategy and architecture ownership, vendor and build-versus-buy decisions, technical due diligence before funding or acquisition, and coaching an internal lead toward the permanent role.

Typical engagement

Discovery: 1–2 weeks
First release: 4–8 weeks
Team: Senior specialists only
Ownership: 100% yours
