Technology strategy and build-vs-buy calls, architecture review, vendor evaluation and oversight, hiring bar-setting, and translating engineering to the board — judgment, part-time; execution stays with the team.
Non-technical founders buying development (someone must check the vendor's homework), companies between technical leaders, and PE portfolio companies needing diligence-grade oversight.
Advisory (few hours weekly), operational (owning a workstream like a replatform), or interim (bridging a hire) — clear scope and decision rights in writing either way.
Fractional leadership can't substitute for daily engineering management at scale — it's the strategy-and-judgment layer, and it should help you hire its full-time successor when the time comes.
Skipping the discipline this article describes until an incident, audit, or stalled project forces it — every practice above is cheaper adopted early than retrofitted under pressure.
Let's discuss how we can help you with fractional cto.
