We’re building the agency of tomorrow

1GS operates as a House of Agency Brands, with each brand purposely built to lead within a defined service niche. All brands run on a shared services infrastructure spanning finance, HR, creative operations, and technology, enabling efficient scaling.

This is what that looks like…

Human First

We believe the best work still starts with people.

AI Native

We put AI to work beside our people, so they can do more.

Built to Adapt

We evolve as technology, markets and our clients’ needs change.

The way we build matters just as much as what we build.

So while our business will keep evolving, the values behind it won’t.

Don’t be greedy

There’s enough to go around for us all to win! We’ll only work on your project if there’s a clear win for everyone involved.

Think long-term

We’re more interested in developing long-term partnerships – not racking up our number of clients for bragging rights.

Do good

We’re contributors. It is our privilege to support charities and community-based projects in Jamaica.

Our Team

1GS Leadership.
