AI consulting & angel investing

Hands-on AI operator & angel investor.

Collapse decision time. Raise the bar. Reduce the toil.

I help executive teams move AI from slides into production. I also write $10-75K checks for founders doing the same. Cold intros welcome. You’ll get a clear yes/no within 48 hours when you include a deck or data room.

About

Operator and investor with 10+ years in product and strategy. I work with founders and exec teams to turn complex, multi-step operations into reliable decision systems - the kind that ship to production, stand up to scrutiny, and actually change how work gets done.

I prefer small, senior teams and measurable shipped outcomes over demos. I’m comfortable partnering on short, outcome-first sprints or working embedded when that’s the right fit.

I selectively back longevity - extending healthy life is worth doing.

I can help with:

  • • Prioritize the 1-2 AI bets with the clearest ROI
  • • Ship production features with evaluation and guardrails
  • • Prove large-scale impact with audit-ready metrics; keep what works

Principles

How I operate

  • Default to production.
  • Measure shipped impact, not demos.
  • Small, senior teams.
  • Evaluation-led; model/vendor-agnostic.
  • Auditable decisions; human oversight where it matters.

Advisory

AI consulting (selective)

I partner with leadership to turn AI from slides into shipped features. Work ranges from short, outcome-first sprints to embedded roles. Typical impact: move high-stakes decisions from hours to minutes, cut errors with clearer accountability, and meaningfully reduce manual work.

Strategy & roadmap
  • • Use-case triage & ROI modeling
  • • Buy vs. build; vendor selection
  • • Organization design & capability building
Shipping & performance
  • • LLM evaluation, guardrails, and retrieval
  • • Data pipelines & feedback loops
  • • Practical MLOps & cost control
