John Bentley, II
Fractional CTO | Product Journey Guide at Product Journey Group
Based in United States · 35+ years experience
Summary
Fractional CTO for startups past MVP. I fix slipping delivery, strengthen architecture, and build systems that scale.
About
Most startups don’t struggle because of bad ideas. They stall when growth exposes gaps in technical structure, leadership, and delivery discipline.
I step in when a product exists, a team is in place, and execution has become unreliable — releases slip, plans aren’t trusted, architecture shows strain, or basic security and scalability practices haven’t kept pace with growth.
With over 30 years of experience as a CTO and product leader, I help founders regain control of delivery and build systems that support the next stage of scale.
My work focuses on:
Post-MVP stabilization
Architecture evolution and scalability
Engineering team structure and accountability
Product and technical alignment
Practical security and operational maturity
I have led initiatives across telecommunications, finance, and SaaS — environments where uptime, data integrity, and disciplined execution matter.
As a Fractional CTO, I provide senior technical leadership without full-time overhead — clarifying priorities, strengthening architecture, and restoring predictable delivery so momentum becomes durable growth.
