Despite a boom in AI sales development representatives (SDRs) leveraging large language models for personalized outreach, venture capitalists express caution. Startups like Regie.ai and Docket are thriving, yet the long-term effectiveness of their solutions remains uncertain. Investors highlight the rapid market success of multiple AI SDRs, but worry about potential competition from established players such as Salesforce and ZoomInfo. Many startups are experiencing impressive growth rates, but the sustainability of their business models is still in question. The landscape poses both opportunities and risks for investors in AI-driven sales.
