Why we make so many friends

When we were starting 18 years ago, before we had a single client, we pitched to PepsiCo. They told us everything sounded great, but they couldn’t possibly buy from us – we were too small, too unknown! (How things change.)

So we told them we’d do all their compliance work for three months before they needed to pay, and that’s what we did. Then they became our first customer and the rest is history.

We still do this with every client. All you do is sign-up and we get to work! If after three months there are any problems, we simply part as friends.

That’s the way we do things here. It works.
