A pinkie promise is a binding arrangement between two parties. It's usually signified by intertwining your pinkie finger with the person you are making the promise to - though we won't force you to uphold this practice!
To us it signifies how serious we are about making a binding promise to our customers that we bring determination, focus and commitment to our relationship with you.
Its a promise that seals the deal - it's like saying "Cross your heart?" - but that's not so catchy for a company name!
