Enterprise Marketing Talent Without the Million-Dollar Minimum
We bring the caliber of growth marketing built inside the biggest agencies, consulting firms, and tech companies to the small and mid-sized businesses those firms usually price out.
25+ Years of experience built inside Ernst & Young · Microsoft · IPG · Publicis · Yahoo.
Big-Agency Know-How Shouldn't Take a Big-Agency Budget
The best marketing talent has always been locked behind seven-figure minimums. For a small or mid-sized business, that's meant three bad options: do it yourself, gamble on a freelancer, or sign with an agency that hands you a junior team. We built Purple Shamrock to close that gap, senior, enterprise-grade growth marketing, sized and priced for businesses ready to scale.
What We Do
Paid Media Management
We manage your ad spend with the same rigor as a seven-figure account, aimed squarely at your growth.
Analytics & Insights
We show you exactly what's working and what's wasting money, in plain English.
Enterprise-Level Thinking Meets Entrepreneurial Execution
The pedigree, without the gate. Enterprise-grade experience, entrepreneur-sized access.
Senior-led. Real senior talent on your account, never a junior team learning on your dime.
Proven, not theoretical. We run this same playbook on our own ventures, so you get tactics tested with real money on the line.
