As a fractional CTO, I embed with your leadership team 2-3 days per week, providing the same caliber of executive technology leadership you would get from a full-time CTO — scaled to your stage and budget.
A typical engagement runs 6 months to 2 years and includes architecture and roadmap development, engineering team building and hiring, vendor strategy, board-level technology reporting, and hands-on delivery leadership. I am not just an advisor — I operate.
