What Agency Leaders Say
Agencies using StackCertified operators to add capacity without adding chaos.
"We added two Klaviyo email builders through Staff Stack. They passed their certification tests before we even interviewed them — we could see their actual flow builds. Now we're shipping 40% more campaigns without adding to our core team."
Sarah Chen
Founder, Retention Agency (Klaviyo Partner)
"Our strategists were drowning in campaign builds and reporting. The ad ops assistant we hired handles all the execution work now. Our strategist time freed up by 15+ hours per week — exactly what we needed to take on more clients."
Marcus Williams
Head of Operations, Performance Media Co
"Project overflow was killing our deadlines. We brought on a StackCertified Shopify developer who hit the ground running — their certification included fixing a real bug under time pressure. That's exactly the test that matters for our work."
James Park
Technical Director, Shopify Plus Agency
"The QA specialist we hired catches issues our team was missing. Links, rendering, UTMs — they have a checklist for everything. Our error rate dropped significantly in the first month. Worth every penny."
Emily Rodriguez
Managing Partner, Email Growth Partners
"We needed reporting capacity fast. The analyst we got can build Looker dashboards, automate reports, and actually understands attribution. They proved it in their certification — not just talked about it in an interview."
David Kim
CEO, Conversion Lab Agency
