Technical leadership when
it matters most
CTO-as-a-Service provides senior technical guidance without the cost of a full-time hire, helping founders make confident technology decisions that support product growth and stability.
What CTO-as-a-service means at Wise
CTO-as-a-Service at Wise is a senior advisory role focused on direction, clarity, and decision-making. It is not staff augmentation and not day-to-day engineering management. Our Fractional CTOs bring experience from working with multiple startups and growing platforms across different stages.
This perspective helps teams avoid common mistakes, choose appropriate solutions for their current phase, and prepare for what comes next. The role focuses on strategy, architecture, priorities, and trade-offs. It helps founders and teams move faster with fewer wrong turns.

- A technical audit has identified architectural or process gaps
