Nearly two decades across Sydney and Perth: incubating 100+ startups, growing a cabin business from idea to profit and now shipping with AI.
I started my first business in France straight out of high school. In Sydney I was Head of Product at Pollenizer, building the product team that launched 100+ startups and sold one to Yahoo!7 for AU$40M. In Perth I grew Heyscape from an idea to a profitable business with 25 off-grid cabins. Now I build AI products on my own and lead AI projects on contract, most recently at Respondent.io, where I built an autonomous AI agent that runs their recruitment campaigns.
Weekly gatherings of things I read on the state of the industry.
I have been building software with AI tools all year, and the thing I did not expect is how quickly the conversation moved from "what can this do" to "who is paying for it".
Four products I designed, built and run on my own. Each case study covers the architecture, the numbers and what I learned.
Made AI coding usage measurable across every tool.
A Mac menu bar app and web dashboard that track tokens, cost and output across Claude Code, Codex, Cursor and Mistral Vibe.
Production grade setup in one minute.
A free Mac app that gives each new project its own AWS account, GitHub repo, keyless deploys and agent guardrails.
Made flaky, metered AI video reliable enough to sell.
Turns a handful of photos into a cinematic short film in minutes.
Made live voice AI hold up on a real phone line.
An AI receptionist for Australian tradespeople and real-estate agents: it answered missed calls, triaged every message and called people back.
My last three posts on X.
Read on X ↗That kinda of visualisation UI reminds me of the Winamp’s skins (skins.webamp.org). Completely useless but somewhat desirable :D

Read on X ↗@Scobleizer I don’t understand how/why this👇 is not a thing in VR yet? Seems to me like an obvious banger for Apple (and others) yet no signs of it.
