Letter AI Raises $40M for Sales Agents
Letter AI, a sales enablement platform, has secured a $40 million Series B funding round. The company also launched a new deal-level guidance tool that functions as a contextual AI agent for sales teams. The product embeds AI directly into revenue workflows to provide proactive orchestration rather than just passive data.
- The Series B round was led by Battery Ventures, bringing Letter AI's total funding to nearly $51 million across two rounds raised in just four months. - As part of the funding deal, Battery Ventures partner Brandon Gleklen will join the company's board of directors. - The company's previous $10.6 million Series A in October 2025 was led by Stage 2 Capital, which brought Mark Roberge, the founding CRO of HubSpot, onto the board. - Founded in 2023 by CEO Ali Akhtar and CTO Armen Forget, the company positions itself as an AI-native platform, aiming to differentiate from legacy competitors who are adding AI features to older systems. - The new tool, Letter Compass, provides deal-specific coaching and personalized messaging by integrating directly with live data from CRM systems. - Enterprise customers include major tech companies like Lenovo, Adobe, Plaid, and Zip. - The global sales enablement platform market was estimated at over $5 billion in 2024 and is projected to grow to more than $12 billion by 2030.
