What We’re Looking For We are looking for individuals who: Have experience in the hospitality or restaurant sector Have strong relationships with restaurant owners or operators Are comfortable with commercial conversations Understand restaurant operations and economics Are proactive and self-motivated Industry access and relationships are more valuable than formal sales experience. Compensation This is a performance-based partner opportunity. Partners earn: Onboarding commissions for each restaurant launched Recurring revenue share from restaurant sales Additional incentives as their portfolio of restaurants grows Your earning potential grows as your network of partner restaurants expands.
