Product executive at a payroll platform"Everyone talks about being ‘AI-enabled,’ but most just have a chatbot using the same model as everyone else. Limited value for a small company looking toward a Series A. This allows us to leverage specialized tax AI without having to build it ourselves. It provides direct user experience and real value to our customers – it strengthens our entire AI story."
Tax compliance expert at a vertical payroll platform"The AI agent is a real benefit for handling tax scenarios and state reciprocity, as it cuts our research time down significantly by immediately spelling out calculations, helping us quickly check configurations, update employee profiles, and correct client information much faster than submitting a support ticket or tedious testing in Postman."
