We just got backed by a16z @speedrun. We believe the next interface is natural language. We call it the Language User Interface (LUI) An interface that talks to your APIs, understands your product, and lets users get work done with natural language (thread below)
I’m launching Swish AI - an ai basketball coach on August 1st. My biggest lesson from launching a B2B app 2 years ago is that distribution is everything. This time around, I am warming up distribution prelaunch. Before the app hits the AppStore I want: - 500k impressions - 10…

I’ve worked on 5+ failed startup ideas in the past 3 years. I’m the moment they felt devastating but each helped bring me to the next opportunity. Sharing some of my losses: 1. Reminest - spent 7 months building a consumer app without understanding distribution was everything…
One of the lesser talked about benefits of doing IRL jobs (doctor, farmer, etc.) is that you don’t have to spend all day looking at a screen.

Posted my new app demo on Reddit and it got….. Pleasant responses?! This means it’s gonna flop right.

The key to building a LLM wrapper is you can’t build one in a market so big (cursor, windsurf) that the providers will eventually want to take over (Claude code). You have to build a niche enough tool that it adds tremendous value to people but will likely remain untouched by…
Hit my first 1K MRR of online money! Makes you feel like anything is possible. I wanted to better document the process - both wins and losses. Follow along for the journey building 4 businesses in 4 months.
45 mins from Calgary you get the most beautiful scenery on this earth. 45 minutes from Toronto you get Scarborough.


I accidentally made cursor for shortform video. A month ago I started a content agency and I quickly realized if I wanted to scale it I needed to automate or hire. I started making an agent that takes a video transcripts + user guidance and writes jsx scripts to add subtitles,…
