Origin of Company Name
"RainbowLink Inc." comes from the software name of "Rainbow-Link ®". Several years ago, before the foundation of RL, the OwnerPresident of RL created many little software and tested them. The OwnerPresident of RL planned to create a big sales promotion software by using the little software. When the OwnerPresident of RL gave colors to each little software and arranged them in a straight line, the beautiful rainbow appeared. By having watched the rainbow, the OwnerPresident of RL named the big sales promotion software the "Rainbow-Link". You can see the rainbow at RL's site now.
