Nico Purnomo

Product manager · London, UK

I'm a product manager working at the intersection of data, ML, and product. Right now I'm building Pollen at Sainsbury's Tech — an industry-first multi-channel measurement platform that helps Nectar360 quantify the real impact of retail media at a scale no UK retailer had attempted before.

Before that I shipped agentic AI workflows at Vortex IQ (Techstars '24), led a knowledge graph PoC at PEXA Group (Australia's national digital property platform), and built growth analytics from zero at an early-stage proptech startup. I hold a Master's in Business Analytics from Melbourne Business School and a Bachelor of Commerce from the University of Melbourne.

This site is where I share the analytical and writing side of that work — interactive data projects, articles on ideas I find interesting, and the occasional rabbit hole. There's also a terminal version if you prefer exploring that way.
