SMASH, WHO WE ARE?

We are agents for tech professionals in Costa Rica and Colombia that help them build careers in the United States.
We believe in long-lasting relationships with our talent. We invest time getting to know them as individuals and understanding what they are looking for as their professional next step.
We aim to find the perfect match. As agents, we make sure to pair our talent with our US clients, not only by their technical skills but as a cultural fit. Our core competency is to find the right talent, fast.
We purposefully move away from the “contractor” or “outsourcing” type of relationship. Our clients don’t want contractors or “just a service.” Neither does our talent.
