About
At fourteen, I walked into university. By sixteen, I'd graduated. Not because I was in a rush, I just couldn't sit still. That restlessness took me to Go1, a $3bn edtech unicorn, where I spent four years scaling GTM systems across 12 products. Then I went full-time building: a stealth healthtech startup using computational biology to personalise health, a Chrome extension that reframes how people spend money, and an NFP that gave free tuition to 300+ students. I also launched a Thai-pizza fusion restaurant. That one was a really bad idea.

The AI Trust Tax in
B2B Sales

B2B companies are replacing sales representatives with AI to cut costs, but they ignore the "Trust Tax," the lost revenue when buyers reject AI-generated communications. When an email says it was drafted by AI, trust drops and reply rates tank.


Using a purely virtual simulation where AI acts as both sellers and buyers, this research bypasses traditional ethics constraints. A 10,000-iteration Monte Carlo financial model finds the exact threshold where revenue lost from the Trust Tax wipes out the software's cost savings, making human salespeople more profitable.
