as reported
Reported by LangChain (Dec 2025 to Mar 2026): lead-to-qualified-opportunity conversion up 250% and 3x more pipeline dollars in the same period. Follow-up on lower-intent leads up 97%, higher-intent leads up 18%. Reps reclaimed 40 hours a month each (1,320 hours across the team); 86% weekly active use.
Case study (the vendor's own team). LangChain's GTM agent triggers on every new Salesforce lead, first looks for reasons not to email (a fresh support ticket, a teammate who already reached out), then researches the CRM record, Gong calls, LinkedIn and the web and drops a draft in the rep's Slack with its reasoning and sources. The rep sends, edits or cancels. When a rep edits, an LLM compares the two versions and saves that rep's style notes, so the next draft starts closer to how they write.
