Case Study: SISU Guard achieves 900% conversion increase and 55% sales growth with BigCommerce

Bigcommerce’s mobile optimization and automations help massively improve conversion

SISU Guard, founded by oral surgeon Dr. Jan Akervall, makes low‑profile performance mouthguards and had generated over $1M by year two—but growth was stalled by a poor mobile shopping experience. Nearly half of site visitors were on mobile, yet mobile bounce rates hit about 90%, and the company also needed a platform to support both B2B and B2C sales plus backend automations.

After a quick migration to BigCommerce and a responsive site redesign with API integrations and 250+ app options, SISU gained automated customer communications and abandoned‑cart recovery tools that streamlined operations and improved conversion. The changes drove a 900% increase in conversion rate, a 55% rise in sales and a 32% increase in average order value.
