Eric Siu

I'm Eric, founder of Single Grain, an AI-native marketing agency that runs SEO, AEO, paid media, and content as systems inside your accounts.

I also built Single Brain, a managed company brain plus revenue-agent layer. I co-host Marketing School with Neil Patel and host Leveling Up. I bought a failing SEO shop for $2 and rebuilt it around execution.

Ask me about company brains, AI-native agency ops, or growth that does not need more headcount.
