Hiring a Fractional CTO: The Scope, Cadence, and Red Flags
I have been the fractional CTO for over 20 SMB and SaaS companies at various stages. I have also watched founders hire the wrong person for this role repeatedly, in ways that are entirely predictable and largely preventable. This note covers what the role actu
Hiring Your First Engineer: The Trial Project That Actually Predicts Performance
