The company identifies user conversion to paid subscriptions as critical to its financial success, with only 9% of its 130 million monthly active users being paid subscribers. This creates a strong need for tools related to A/B testing, user analytics, CRM, and marketing automation to improve conversion rates and reduce churn.
