Our take on Ambaum
Ambaum operates as a Seattle-area Shopify Plus agency founded by former merchants who have themselves navigated the challenges of building and scaling ecommerce businesses. Since 2016, Ambaum has provided both technical development services and strategic partnership guidance, positioning themselves as fractional CTOs for the brands they work with. Their founder experience means they bring merchant-first perspective to every engagement, understanding the business implications of technical decisions rather than viewing ecommerce as purely a technology problem.
The agency's particular strength lies in their combination of technical excellence with merchant empathy—they understand both the technical capabilities of Shopify Plus and the business dynamics of scaling online commerce. Ambaum provides comprehensive services spanning platform migrations, custom app development, ongoing technical support, and strategic guidance on technology investments. Their emphasis on long-term partnerships rather than project-based engagements reflects their merchant-first philosophy—they invest in clients' long-term success rather than moving quickly between projects.
What distinguishes Ambaum is their merchant founder background and fractional CTO approach—they bring business insight alongside technical proficiency, understanding that technology should serve business strategy rather than driving it. For growing to enterprise-scale brands seeking a Shopify Plus partner that combines technical excellence with merchant perspective and can provide strategic guidance on technology investments, Ambaum offers unique value rooted in founder experience navigating the same challenges their clients face.
