CTO Consulting Service

Fractional CTO: a senior technology leader who dedicates a fixed percentage of their time to your company on a recurring basis, typically 1-3 days per week. Best for companies that need ongoing technical leadership without a full-time executive hire.

On-demand CTO: a senior technology leader engaged for a specific project or period: a product launch, a fundraising round, a technology audit. Engagements are scoped by deliverable or duration rather than recurring time commitment.

Concrete deliverables from a unicrew CTO engagement typically include:

• 1. Technology roadmap: a 12-24 month prioritized plan with build sequence, stack recommendations, and cost estimates.
• 2. Architecture decision records: documented rationale for major technical decisions, ensuring continuity beyond the engagement.
• 3. Engineering team assessment: evaluation of current team capabilities with a hiring plan or vendor shortlist.
• 4. AI readiness assessment: evaluation of where and how AI can be integrated into your product.
• 5. Vendor and tool evaluation: structured comparison of build vs. buy options with selection rationale.
• 6. Technical due diligence report: for fundraising, M&A, or major partnership decisions.
• 7. Onboarding documentation: structured handoff materials so your next technical hire can continue the work.

Yes, this is one of the most common reasons startups engage a fractional CTO. Investors and acquirers assess your technology stack, architecture decisions, technical debt, security posture, and team capability.

A unicrew fractional CTO can prepare the technical documentation, respond to investor questions, and address flagged concerns before they become deal blockers. We have supported technical due diligence for seed, Series A, and Series B rounds across Fintech, Healthcare, Hospitality, and Logistics.

CTO consulting is an operational role: the CTO consultant leads technology decisions, manages technical teams or vendors, owns the architecture, and is accountable for delivery timelines.

Technology advisory is a strategic role: the advisor provides expert input on direction, evaluates options, and challenges assumptions, without operational ownership.

If you need someone to make decisions and drive execution, CTO consulting is the right fit. If you need a senior voice in the room for strategic decisions while your internal team handles execution, technology advisory may be sufficient.

Engagement length depends on the model and scope:

• 1. Fractional CTO: typically 3-12 months, with most clients renewing after the first term once the relationship is established.
• 2. On-demand CTO: typically 4-12 weeks, scoped around a specific milestone (launch, fundraise, architecture review).
• 3. Full-time interim CTO: typically 3-9 months while a permanent hire is sourced or an internal candidate is developed.
• 4. There is no minimum engagement period. We scope based on what you actually need.

This is a common combination. unicrew can provide both: a fractional or on-demand CTO who designs the architecture and technical direction, alongside a dedicated development team who builds it. 

This structure works particularly well for early-stage startups that have a product vision but no technical co-founder, or for scale-ups that need to move faster than their current team can support. The CTO and development team are coordinated by unicrew, so you have one point of contact and one delivery accountability.

All CTO engagements include structured documentation requirements: architecture decision records, technology roadmap documentation, vendor and tool rationale, and onboarding materials for the next technical leader.

Engagement transitions are planned, not abrupt. We typically structure a handover period of 2-4 weeks. If you choose to continue with a different unicrew CTO consultant, institutional knowledge is retained within the team.
