Agile AffiliateLogo Design Contest

We are a company that targets the CrossFit fitness industry. We provide a simple billing and member management solution to gym owners. Our end goal is to be simple, intuitive and unobtrusive.
The product allows gym owners to very quickly manage gym memberships, subscription billing, individual purchases and track profitability of the gym over time.

The target audience is new and existing gym owners. We initially target new gyms as we appeal more to new gyms, however we also cater to existing gyms by providing them a migration path from other member billing systems.

I would like to see the following possible color combos:
green & gray
or
green & white
or
green & white & grey

Until now we have a very simple logo that was simply based upon a thin font. We want new and fresh and modern. We like the thin font style as it represents simplicity. We want to convey simplicity.
