Growth Marketing Intern @ Proof of Talk
About
I’m Sithum, a digital marketing specialist with around three years of experience working across B2B and B2C environments. I come from a diverse academic background in Material and Nano Science Technology and transitioned into marketing, where I apply a structured, data-driven approach combined with creativity and experimentation. I’ve worked in agency and startup settings, supporting brands from early stage businesses to international clients. My experience spans content strategy, social media management, performance focused campaigns, go to market support, and influencer marketing. I’m particularly interested in building clear foundations for growth, aligning strategy, messaging, and execution rather than chasing short term wins. Currently based in Germany, I enjoy working closely with founders, clients, and cross functional teams to translate business goals into practical digital marketing strategies that drive measurable results.
