PartnerStack is a dedicated ecosystem platform built specifically for B2B SaaS companies to accelerate growth through partnerships. You can manage every stage of your partner journey—from initial recruitment and onboarding to automated lead tracking and commission payouts—all within a single interface. By centralizing your affiliate, referral, and reseller programs, you eliminate the manual overhead of managing multiple spreadsheets and disparate tracking links. You can provide your partners with a dedicated portal where they access marketing assets, track their own performance, and receive automated payments in their preferred currency. The platform also features a built-in marketplace that connects you with over 800,000 active partners already looking for new software to promote. This helps you scale your indirect sales channels faster while maintaining full visibility into which partners are driving the most revenue for your business.

Wunderkind helps you unlock hidden revenue by identifying the anonymous traffic hitting your website. Instead of losing touch with visitors who don't sign up, you can recognize them across devices and trigger high-performing, personalized messages. You can scale your reach by sending automated emails and texts based on specific user behaviors like cart abandonment or category browsing, ensuring your marketing hits the right person at the right moment. The platform integrates directly with your existing tech stack to supercharge your performance marketing. By focusing on first-party data and identity resolution, you can decrease your reliance on third-party cookies and expensive retargeting ads. It is primarily designed for mid-market and enterprise e-commerce brands looking to maximize their owned-channel conversions and build long-term customer relationships.
