Fractional CTO Services
Nocelion provides senior technology leadership for organizations that need CTO-level judgment but are not ready for, or are between, a full-time CTO. Every engagement is grounded in Jon Hathaway's 25 years of technology operating experience, including leadership at Fortune 500 scale.
What Makes This Different
Most fractional CTOs come from advisory backgrounds. Jon comes from an operating background. He has been the person responsible for keeping the systems running, shipping the product, managing the team, and reporting to the board. That is the difference between advice and judgment.
How It Works
Nocelion adapts the level of involvement to what the organization needs. For some clients, that means monthly strategic reviews and architecture oversight. For others, it means full operational authority through Jon as interim CTO. The engagement model adapts to what the organization needs, not to a predefined service package.
Common Scenarios
- CTO departure or leadership transition
- Board mandate for technology transformation
