Fractional CTO for AI startups

Build the right AI product before you build the expensive one

Work with Sam Petrenko on AI startup product scope, SaaS architecture, MVP decisions, and the technical systems behind commercial growth.

This is for founders who need CTO-level judgment, not another backlog. The work connects product risk, AI workflow design, engineering choices, and revenue strategy.

Direct answer

A fractional CTO for AI startups helps decide what to build, what to avoid, where AI should be used, where deterministic software is safer, and how to create a roadmap a small SaaS team can actually ship.

Where this helps

  • AI SaaS MVP scope and technical architecture
  • Internal AI workflow automation for operations or GTM
  • DevTool and B2B SaaS signal intelligence products
  • Technical due diligence before hiring, rebuilding, or fundraising
  • Roadmaps that connect product, engineering, and revenue

Proof from shipped products

Across Fruitful Code, Webinse, and Mates Marketing, the team shipped productized ecommerce extensions, WordPress products, templates, websites, and internal tools before turning the same product discipline toward AI-assisted SaaS and GTM systems.

  • 70+ magento extension records
  • 30+ wordpress products and sites
  • 25+ template and design assets
