An all-in-one
marketer who
builds the system.

I'm Quentin — a marketer working in ads, SEO, and growth since 2011. I stand up marketing functions from zero (tracking, funnels, ad accounts, content, reporting) and run the channels on top. Today I lead a $1M+/month paid-media practice at Buyerlink and audit paid + SEO programs through On Q Marketing.

§ 02 — Approach

Great marketing is the patient work of testing assumptions, reading the data honestly, and reinvesting where the math is working. No vanity metrics — just CPA, ROAS, and pipeline that compounds.
