I help the rich
get richer.

I'm Kunal Johar. I co-founded OpenWater, grew it to $10M ARR, and now serve as CTO after its PE acquisition. I build software, invest my own money, and write about what happens when AI meets capital. This is my notebook — not a consulting pitch.

I'm the CTO @ ASI. I also built API2PDF and contribute to open source.
