The Opportunity

Problem

Remote founders face high fees and complex setup for international payroll compliance and tax withholding when managing distributed teams using tools like Deel.

Solution

WireTax lets founders simulate tax impacts before paying, then generates payslips with withholdings baked in. Connect your bank or Stripe, run scenarios for hires, and export for accounting. Ditch Deel's overhead with instant, visual compliance tools.
