Staff Stack
Built for Agencies

We Built Staff Stack to Solve the Agency Staffing Problem

Agencies need operators who can ship. Not candidates who interview well. We created StackCertified to prove the difference.

The Problem We Saw

What Agencies Were Getting

  • Generic VAs who need weeks of training
  • Freelancers who disappear mid-project
  • Hires who interview well but can't execute
  • No accountability after placement

What Agencies Actually Need

  • Operators tested on actual agency tasks
  • Full-time commitment with clear expectations
  • AI-native workflows built in
  • Ongoing support and performance tracking

So we built a certification system that tests what actually matters: can this person ship the work your agency needs?

Meet the Operators

Our operators are based in the Philippines — a country known for strong English communication, cultural alignment with Western agencies, and a deep talent pool in digital marketing and development.

But unlike traditional offshore hires, every Staff Stack operator earns their StackCertified badge through practical testing. They prove they can ship before they start.

What We Believe

These principles shape how we certify operators and support agencies.

Operators Ship

We don't place 'candidates'. We certify operators who can execute on day one. Every StackCertified hire has proven they can ship real work.

AI-Native Workflows

Modern agencies use AI tools. So do our operators. Every certification includes AI workflow proof — prompt to deliverable.

Quality Over Volume

We don't flood you with resumes. We send pre-certified operators with scorecards you can actually evaluate.

Ongoing Accountability

Certification is step one. StackOps keeps operators performing with weekly KPI check-ins and QA systems.

The Stack Approach

Three mechanisms that make Staff Stack different from generic staffing agencies.

StackCertified

Role-specific practical tests that prove operators can do agency work — not generic assessments.
