AI consulting & angel investing

Hands-on AI operator & angel investor.

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

I help exec teams move AI from decks to production. I also write $10–75K checks for founders doing the same. Cold intros welcome. Yes/no ≤48 hours with a 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 shipped impact over demos. I’m comfortable partnering on short, outcome-driven sprints or working embedded when that’s the right shape.

I selectively invest in longevity, believing that extending healthy life is worthwhile.

I can help with:

  • • Prioritizing the 1-2 AI bets with the greatest ROI payback
  • • Shipping production features with evaluation and guardrails
  • • Proving 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 a slide into shipped product. Work ranges from short sprints to embedded roles. Typical impact: hours/days → minutes in high-stakes decisions, fewer errors with clearer accountability, and noticeably less manual toil.

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