I build consumer products that acquire their own users, and I build them with AI.
From 2018 to 2025 I was Founding GM & Head of Product at AppSumo Originals. I took 10+ products from zero to 1.22M+ registered accounts in 200+ countries and territories, competing with Calendly, DocuSign, Mailchimp, and other big names — but with a fraction of the budget. I once beat Notion for #1 Product of the Day on Product Hunt.
Multiple products I built crossed $1M in revenue and the flagship, TidyCal, has about 450K accounts and has processed $30M+ in payments for its users.
Since then, I've been a Fractional Head of Product & Growth. I've merged 600+ PRs in 2026 with Claude Code and Codex, and I'm a top-ranked builder on Lovable and a Level 3 Proficient Builder, top 10% on Replit.
Today, I help define strategy, write specs, built prototypes, run LLM evals and smoke tests, ship much of the code myself, and measure and iterate to drive results. My focus is on 0-to-1 and 1-to-scale. My client roster this year is AppSumo, FOUND, Table22, and SendOwl.
Open to: Full-time or fractional product leadership roles frontier AI and AI-native companies. If your AI product needs its first, or next, million users, let's talk.
- Ship Sense measures product judgement and taste. It scores 63 models (21 current) on 95 real product decisions, with 95% confidence intervals.
- pm-copilot is an MCP server that connects support tickets and feature requests, so PMs can see what to build next. CI fails if its eval drops below 0.90 F1.
- substack-publisher-mcp is the first MCP server on Substack's official Publisher API.
- Game Night runs 32 browser games with room codes and an AI opponent. Every change runs Playwright tests and full games played by AI players.
- llm-moods powers llmvibes.ai, a live dashboard of how people feel about each LLM, with daily updates and tracking.
- genogramcreator.me maps family history and relationship patterns.
