Herd
Built in: April, 2026 | Stack: Next.js, Supabase, Stripe Connect
A referral platform for B2B SaaS companies that is free until the referrals actually make money. The pricing curve bends as referred revenue grows (cheaper than flat-rate exactly when it matters), the tracking widget is a couple hundred lines, and payouts run on Stripe. The strategy shipped first; the recurring commission engine is the part still in flight.

A small tracking widget inside the merchant's own product captures referral clicks, and Stripe webhooks report the revenue those referrals generate. The bent pricing curve computes what Herd charges as referred revenue grows. The recurring commission engine and automated payouts are drawn dashed: designed, not yet built.
