PartnerStack is a partner relationship management (PRM) platform and affiliate marketplace focused exclusively on the B2B SaaS segment. It has operated since 2015 and is headquartered in Toronto, Canada. In April 2026, the company was acquired by AppDirect and now operates as part of that group.
The platform supports several types of partnership in one place — affiliate programs, co-sell (reseller/agency partners), referral programs and influencer marketing — letting SaaS companies run multiple programs side by side.
PartnerStack works as a marketplace connecting SaaS companies (vendors) with partners — affiliates, sales agencies, influencers and content creators. Marketplace access is free for partners; after joining a brand's program, a partner promotes its product and earns a commission on the resulting sales or subscriptions.
The network states that over 600 recognisable SaaS brands use the platform, and that onboarding a new partner program for an advertiser takes, per its own data, an average of 74 days.

Each brand (vendor) independently sets the commission model for its own program — this can be a percentage of the sale, a flat fee per lead, or a recurring commission tied to an active customer subscription. The platform automates commission calculation and payout, consolidating them into a single monthly invoice for the vendor regardless of partner count.
Among payout methods for partners, user reviews mention PayPal and Stripe. Exact payout thresholds and schedules depend on each individual partner program.
The platform is aimed primarily at affiliates, agencies and content creators promoting SaaS tools and B2B software, rather than classic e-commerce. It works well for publishers with business/B2B traffic, influencers creating content for entrepreneurs, and sales partners. It is less suited to traditional consumer campaigns or the Polish market, since the network's profile is global and product-driven (SaaS) rather than regional.
