I'm Philip, a designer in Deventer who was told the robots would do the designing now. Fine. Twenty years in, BTNG.studio is still my main thing: research, design and experiments that make ecommerce stores sell more. The robots and I build Proviand, Koppel and Doorst.app. Wando is a poster store I run because I refuse to stop making posters.

Currently working on

Connects a Shopify shop to Bol. Stock, orders and returns kept in sync.

In review since September 2026

A marketplace where brands bid to put their logo on your stuff.

Soon

Peppol e-invoicing for Shopify. Makes B2B merchants compliant with EU e-invoicing mandates.

Building

Tells Shopify shop owners what to reorder, based on what they already sold.

Live since July 2026

I looked at how ten makers with more than one product present them on their own site. The pages that work all show the same field.

Koppel is submitted to the Shopify App Store. Proud, slightly nervous and already told once to try again.

Proviand is in the Shopify App Store. Twenty years of building things for other people. This is the first one with my name on it.
