Why the name


“I always loved chemistry as a subject and was thoroughly enthralled by the periodic table. I knew I needed a name to encompass all the unforeseen that was to come. As Carbon is one of the most abundant elements in our bodies, it felt compelling for the business I was beginning to create. I added on a number sequence, and our name was born.”
