Karen Segura | Founder

Karen’s Amazon journey started in 2019 with selling products on 3P. Naturally she was drawn to the marketing and advertising side of the business, deeping her interest to create strong campaign strategies and drive incremental growth.

Since then, shes managed over $7 million in media spend, overseen more than 9,000 successful campaigns, and navigated across 5 product categories, including Grocery, Baby, Personal Care & Beauty, Health & Household, and Industrial. Motivated by the desire to establish an agency that upholds the core values needed in an ads partner to drive profitable and incremental growth on Amazon, she founded Segapex.
