Documented cause
Rulai raised $45M including a $36M Series B in 2020 led by Wing Venture Capital and Scale Venture Partners to build enterprise-grade virtual agents for customer service. Despite Fortune 500 clients, the company burned through capital as enterprise sales cycles were long and deployment costs high. When the LLM revolution hit in 2022, Rulai's proprietary intent-classification approach became technologically inferior almost overnight. The company laid off most staff in 2023 and wound down operations.
