About

I have led go to market in frontier markets for large and small companies, from Google’s initial push into maps in the mid 2000s to Facebook’s early mobile efforts, to pushing the boundaries of social photo editing and drone data, to ultimately launching PayJoy, a Silicon Valley-based fintech, in 20 countries. I led GTM for the Stellar Development Foundation several years, and am currently pushing the boundaries of private AI with Knapsack.

Knapsack OpenClaw App - A safe & simple OpenClaw / Moltbot / Clawdbot app for Mac

Knapsack is an open-source desktop client for OpenClaw / Clawdbot / Moltbot — the AI agent that controls your browser and acts on your behalf. Giving AI that power is dangerous without guardrails. Knapsack adds them: sensitive path blocking (SSH, credentials, .env), prompt injection defense, tool loop limits, mandatory confirmation before sending messages or spending money, and sandboxed scripting. Also bundles a private notetaker, email autopilot, and multi-LLM support. Local/open source.
