Carles Reina: Customer success must evolve into a revenue-generating function, AI will reshape sales teams, and human interaction is critical for outbound effectiveness | 20VC

Carles Reina argues that customer success functions must evolve into revenue-generating operations, with AI fundamentally reshaping how sales teams operate. He emphasizes that despite AI's transformative potential, human interaction remains irreplaceable for effective outbound sales strategies.

Reina's perspective reflects a broader industry shift in how companies conceptualize customer-facing functions. Traditionally, customer success operated as a cost center focused on retention and satisfaction metrics. Reina's thesis positions it as a direct revenue driver, suggesting customer success teams should actively identify upsell and cross-sell opportunities rather than passively managing existing relationships. This reframing aligns with SaaS industry trends where companies seek to maximize customer lifetime value across all operational touchpoints.

The integration of AI into sales workflows addresses persistent challenges around scalability and efficiency. AI tools can automate lead scoring, personalize outreach at scale, and identify patterns in customer behavior that humans might miss. However, Reina's emphasis on human interaction's criticality suggests a hybrid model rather than full automation. Sales teams using AI for intelligence and preparatory work, then deploying humans for relationship-building and complex negotiations, appear most effective. This nuance matters because purely automated outbound strategies often suffer from low response rates and poor conversion metrics.

For crypto and blockchain companies, this framework has specific implications. Customer success in crypto often involves technical onboarding, security education, and protocol navigation—domains where personalized human guidance significantly impacts retention. AI can handle routine inquiries and provide data-driven insights about user behavior, but the technical complexity and trust requirements in crypto justify maintaining human touchpoints. Teams implementing this hybrid approach should see improved efficiency metrics without sacrificing the relationship quality essential for long-term customer value in crypto markets.
