When stepping into a new organization as a fractional CTO, time is both limited and critical. The first 90 days define whether the engagement drives transformation or provides expensive maintenance.
At CTO Advisor Pro, our approach is grounded in clarity, speed, and strategic focus. Whether it's a Series A startup preparing to scale or a legacy enterprise pivoting to the cloud, we focus on three core phases.
Day 1–30: Discovery & Diagnosis
Conduct stakeholder interviews
Map systems to business outcomes
Identify immediate risks or blockers
Day 31–60: Actionable Wins
Implement changes that reduce friction (e.g., delivery velocity, CI/CD)
Clarify team roles and improve workflows
Begin setting cultural norms around quality and accountability
Day 61–90: Roadmap & Handoff
Finalize strategic roadmap (6–12 months)
Mentor internal leaders to own execution
Recommend long-term organizational structure and hiring plan
Results matter. But so does trust. The best fractional CTOs create clarity fast, build confidence with every decision, and leave the organization stronger than they found it.
