2019-2022

Boombrush

Catalyzed was founded by Elias, former founder of Boombrush—a DTC e-commerce brand selling toothbrushes through a subscription model. In just over two years, Boombrush grew from zero to seven-figure revenue.

2022-2024

Ecom Elias

After Boombrush, Elias started working under the name Ecom Elias to help other webshops grow. Again and again, he ran into the same problems: pages missing essential conversion elements, marketing that wasn’t scalable, and teams lacking clear direction.

Catalyzed

Many agencies offered standalone services, but no one looked at the whole picture—from tech stack to creatives, from ads to email. That’s why Catalyzed was founded: an agency that acts as a catalyst for brands with potential.

The team

We understand how it works

We work with a mix of top senior freelancers and in-house experts. Heavy hitters with proven track records who know how things work—ready to jump in when the job calls for it.

We’ve built multiple webshops from the ground up and helped established brands break records. Sure, sometimes you stumble along the way. That’s how you learn what works—and it’s how we help you avoid mistakes when you scale up.
