Srdjan Stojadinovic is Co-Founder and Chief Marketing Officer of Omnius, the B2B SEO and GEO agency based in London and Belgrade, Serbia, focused on SaaS and fintech. He writes much of the firm's public playbook on product-led SEO, programmatic content, and AI-search visibility.
From PetGuards to SaaS Marketing
Stojadinovic began studying digital marketing in 2015 with a focus on SEO. A GOstudy profile places early projects such as PetGuards before a shift into SaaS and fintech content strategy for international startups including Skylead, lempod, and lemlist.
The same bio names him a co-founder of Omnius and of iCheckout, plus the ecommerce brand Mars Activewear. Omnius's own materials say the agency was founded in 2022 by people who had spent more than a decade building demand inside software founding and management teams.
Marketing Leadership at Omnius
As CMO, Stojadinovic owns much of Omnius's published education: SaaS SEO audits, programmatic playbooks, fintech case studies, and AI-search ranking guides on the Omnius author page. The firm caps new clients, works only organic search and GEO for software companies, and runs offices in London, Belgrade, and Dubai.
He describes his own craft as product-led SEO that positions SaaS and startup brands in Google and LLM answers.
Teaching SEO on GOstudy
Beyond client work, Stojadinovic teaches SEO and content marketing to beginners on platforms such as GOstudy and publishes high volumes of how-to and case-study writing for Omnius. The GOstudy bio notes he prefers not to stay in one place and aims for a digital-nomad working style.
His Omnius co-founders include Ana Pantić and Mat Golubović.
