Services

Three ways to engage, from ongoing leadership to a focused strategy sprint. Every engagement starts with a free intro call to scope the work.

Ongoing

Fractional Product Leadership

An experienced CPO/SVP in your leadership team without the full-time hire. I own product outcomes alongside you.

  • Vision, strategy, and force-ranked roadmap ownership
  • Sprint planning, prioritization, and capacity allocation with engineering and data science
  • PM hiring, coaching, and product operating model design
  • Board and investor material preparation

For seed to Series B teams that need executive product leadership now, not in two quarters.

2-4 weeks

AI Product Strategy Sprint

A focused engagement that turns AI ambition into a concrete, sequenced plan your team can execute.

  • Product vision, positioning, and competitive landscape
  • Roadmap with force-ranked priorities and success metrics
  • Pricing, packaging, and go-to-market alignment
  • Readout for founders, boards, or leadership teams

For teams deciding where AI fits in the product, or how to rebuild the roadmap around it.

Hands-on

AI & LLM Build Advisory

Technical product guidance from someone who builds with these tools daily, not just talks about them.

  • LLM feature and agent design: RAG pipelines, evals, model selection
  • Working Python prototypes built with Claude Code and LLM APIs
  • Eval frameworks so quality is measured, not guessed
  • Partnership with your engineers and data scientists to productionize

For teams shipping LLM features that need to work reliably in front of customers.
