The primary difference is the strategic vs. operational focus. A full-time CTO is tangled in daily operations and firefighting. A fractional CTO remains above the daily struggle. Their value is in their strategic time, focusing on the high-level "why" and "what" while your team handles the "how."

You're an early-stage startup with non-technical founders. -
You're scaling and the technology is starting to creak (the architecture that got you to $1M ARR won't get you to $10M). -
You're in a CTO transition and must maintain momentum while searching for a full-time replacement. -

Your core is deep, proprietary technologyIf your startup is built on fundamental scientific research or novel tech, you need a full-time, equity-holding technical co-founder. -
