What We Love
Plug in Useful

Plug in Useful is a family of Shopify apps — including Plug in SEO and Plug in Speed — and services that was profitable, growing, and a great fit with our growing Shopify vertical. We loved the great reviews, the growth metrics, and the value-add on the services side of the business.

About the Founder

Plug in Useful Founder Daniel Sim was working in London as a developer for a large online retailer when he decided to leave with a colleague to build SEO products. Back in Copenhagen, he launched a suite of Shopify apps and services.

After close to a decade of growing Plug in Useful, he realized he wanted to get back to making, vs. marketing.
