About Harris Karastamatis
I help businesses grow through sales automation and AI-powered operations. I built a fully automated content distribution system managing 11+ social platforms — from a single dashboard, zero manual work.
Founder of Raw Feed News (rawfeednews.com), a 24/7 automated news operation running entirely on cron jobs and AI agents.
Through Growth Insider, I share practical tactics on sales automation, social media growth, and AI agent workflows — from someone who actually builds the systems, not just talks about them.
