AI platform that provides real-time sales guidance by connecting enablement content with live deal data

Letter AI, founded by Ali Akhtar (CEO) and Armen Forget (CTO), is an AI-native revenue enablement platform that emerged from Y Combinator and quickly gained traction with enterprise sales teams. The Chicago-based company has raised $40 million in a Series B round led by Battery Ventures in February 2026, just four months after its previous funding, signaling rapid growth in the AI-powered sales enablement space. Their platform addresses the fragmentation in traditional revenue enablement tools by integrating content, learning, coaching, and buyer engagement into a unified system that adapts to individual sellers and live deal contexts.

Key clients like Lenovo report measurable improvements in sales cycle acceleration through Letter AI's real-time deal intelligence. The company differentiates itself by focusing on 'deal enablement' rather than static training, with products like Letter Compass providing contextual guidance during active sales opportunities. This approach has positioned Letter AI at the forefront of what Battery Ventures describes as a 'fundamental reset' in revenue operations.
