How Lindy Uses Claude to Power AI Agents That Deliver 10x Customer Growth

Lindy builds AI agents that work alongside human teams—handling sales outreach, customer support, calendar scheduling, and knowledge work. Choosing the right underlying AI model was existential: a poor choice would mean unreliable agents, lost customers, and broken workflows.

The team ran rigorous model evaluations focused on real-world use cases: navigating ambiguity in large contexts, executing complex tool calls, and handling deeply nested data structures with nuanced reasoning. Claude consistently outperformed alternatives.

With Claude as the default model for nearly all agent calls, Lindy built a platform where almost no customer overrides the default—a rare signal of genuine model trust. The results speak for themselves: 10x customer growth since implementing Claude, a 72% reduction in time-to-qualified-lead for sales teams using Lindy agents, and over 70% of routine support tickets handled automatically.

Sales agents now book 40+ prospect meetings monthly while human reps focus on high-value conversations. Support teams deliver 3–5x productivity gains across workflows.
