Tyne is a referral program built for group chats (where wedding parties, baby showers, and graduations actually decide what to buy). After checkout, customers get a personal referral link and discount code to share by text. When a friend orders, Tyne tracks the sale automatically: no cookies, no clicks. You review each referral, then pay commissions via Tremendous: Venmo, PayPal, bank, or gift card. Set your own rewards. You only pay when the referral drives a real sale.
