Founder

20 years of marketing experience

GrowthStar was founded by Setareh Mahdian, a marketing leader with 20 years of experience across Australia, Canada, and the Middle East. Setareh has led marketing strategy, digital transformation, customer acquisition, CRM and automation, website development, paid media, content, and brand positioning — across healthcare, insurance, SaaS, financial services, professional services, MedTech, and care-sector businesses. That background shaped how GrowthStar works: strategic enough to guide real growth, practical enough to actually deliver it, and experienced enough to understand industries where the decision is never taken lightly.
