Building the affiliate OS for modern SaaS.
Parnex.ai is an engineering-first company building enterprise-grade S2S affiliate infrastructure — backed by operators from Stripe, Segment and Notion.
Our story
Parnex.ai started in 2024 when our founders, after building growth at three different B2B SaaS companies, hit the same wall: legacy affiliate platforms were designed for ecommerce CPA — not modern SaaS billing.
Pro-rated upgrades broke. Churn wasn't tracked. Ad-blockers erased 30% of conversions. And every platform skimmed 5–10% of partner revenue forever.
So we built the infrastructure layer we wished we had — one that treats affiliates the way Stripe treats payments. First principles, first-party, server-to-server.
Infrastructure, not a SaaS tool.
We build for engineering teams. Every surface is a webhook, every config is a primitive.
Aligned with the merchant.
Zero percent of partner revenue. Our incentives only grow when yours do.
Operator obsession.
We've launched dozens of partner programs ourselves. Every product decision starts from real GTM constraints.
Operators who've shipped this before.
We're hiring.
Remote-first, async by default. If you've built infra at scale and want to ship to engineers — let's talk.
