NumeralHQ is building the automation backbone for internet commerce, starting with sales tax compliance. The business problem is that running an online business today means wearing a thousand hats, most of them not the reason founders started their company. Their mission is to eliminate the administrative and accounting burdens that distract businesses from doing what they love. They have helped hundreds of merchants avoid the headache of building giant finance teams just to manage tax compliance and are scaling that impact further by building the automation layer that lets internet businesses stay nimble, compliant, and future-proof.
