Built by a data analyst,
for people who need answers.

I'm Matthew Robinson, a data analytics professional based in Auckland, New Zealand. I've spent years working with data — cleaning it, modelling it, and trying to get it to tell the truth.

Along the way I noticed that most analytical tools are either spreadsheets with too many rows or enterprise platforms with too many features. There's very little in the middle that's genuinely useful for a single decision.

Parsonbird Analytics is my attempt to fill that gap — one small tool, one sharp problem, one release at a time.
