About us

Our mission is simple:

help companies hire the best people - faster and smarter.

Because at the end of the day, employees are a company’s most valuable asset.

We love building products that actually solve real problems.

And nothing beats hearing from customers who say, “this just made my life easier.”

Before OneTeam, we built Sling - an employee scheduling and workforce management platform we founded in 2015.
Today, Sling is used by tens of thousands of businesses across 30+ industries, in over 120 countries, and in every single state in the U.S.

We sold Sling in 2022 to Toast - the leading restaurant POS platform in the world.

But along the way, we saw something clearly:
hiring was still completely broken.

So we started again.

OneTeam is built by exceptional product people, all obsessed with one goal:

building the best hiring software in the world.

And we’re just getting started.Because we believe the future isn’t about managing hiring -
it’s about letting AI run it.

And our belief that the best is still ahead drives us forward every single day.
