Fractional CPO / CTO

Senior product & technology leadership, without the full-time hire.

I work with founders and companies that need senior product and technology leadership but don't necessarily need, or aren't ready for, a permanent executive hire. I step in as a fractional CPO/CTO, bringing strategic clarity and hands-on execution to your product and engineering.

How I Can Help

Product Strategy

Defining product direction, positioning and roadmap clarity so your team knows exactly what to build and why.

Dual-role executive leadership aligning product vision with technical feasibility, so you build the right thing effectively.

AI Product Strategy

Identifying where AI genuinely creates value in your product, and how to integrate it without over-engineering.

0 → 1 Product Development

Taking a product from concept to a robust, scalable first version, with a lean, high-velocity approach.

Structuring product and engineering teams, roles and processes so they scale with the company.

Lean Operations

Designing a lean organizational structure that prioritizes speed and autonomy, so you ship faster with fewer resources.

The Lean Builder Advantage

Most startups hire too many people, too fast. My approach is different.

By leveraging my experience building Vitto solo, I help founders identify exactly what is needed to reach the next milestone. I advocate for a "builder mindset", where product definition and technical execution happen in tight loops, reducing communication overhead and accelerating learning.

  • Eliminate the gap between Product and Engineering
  • Reduce burn rate by deferring non-critical hires
  • Focus on high-impact features that drive adoption
  • Establish technical foundations that scale
  • Build multidisciplinary teams
  • Establish a strong product culture and team spirit

Let's talk about your product.
