PartnerStack is a B2B SaaS partner ecosystem platform that manages affiliate, referral, and reseller programs with automated payouts, a partner marketplace, and recruitment tools.
PartnerStack is a partner ecosystem platform headquartered in Toronto, Ontario that was founded in 2015 and raised $29 million in Series A funding to build the infrastructure that B2B SaaS companies use to launch, manage, and scale channel partner programs — encompassing affiliate, referral, reseller, and agency partner relationships. PartnerStack's thesis is that partner-led growth is the most capital-efficient acquisition channel for B2B SaaS companies past initial traction, and that the operational complexity of managing partner relationships, tracking referral attribution, automating commission calculations, and paying partners across currencies and payment methods creates enough friction that most companies under-invest in partnerships relative to their potential. PartnerStack removes this operational friction through a purpose-built partner management platform that handles the full partner program lifecycle.

The AI acts as a second reader that radiologists can use to catch incidental findings that fall outside the primary reason for a scan — a major source of missed diagnoses.
