The whole purpose of Stripe is to make basic tools for starting an internet business more broadly available and without barriers. The core of our strategy is to eliminate gatekeepers and secret clubs. We’re openly available in 18 countries today (you can see the complete list stripe.com/global) and hundreds of thousands of businesses use Stripe after openly signing up.
Because businesses’ livelihoods and revenue are at stake, we start new products and countries in an invite-only beta so that we can fully test things and fine-tune the details before rolling them out more broadly. We don’t think it’d be responsible to try to maximize the initial product experience at the expense of doing’s what’s best for the businesses who’ll build on it. So with Atlas (and in Mexico), we’re starting in invite-only mode with the goal of expanding access (and making it openly available!) as soon as we can.
I'm sorry we weren't able to get you signed up sooner, but we’d love to have you on board with the beta in Mexico. If you drop me an email (tmf@stripe.com) we’ll send you an invite.
