Locked into a contract? We'll cover it.

If you're mid-term with Highspot, that shouldn't be the reason you wait. Letter AI will buy out your remaining contract obligation so you're not paying for two platforms while you switch.

No waiting for renewal, no double-paying to make the right call now.

Built AI-native. Not brought together over time.

One system from onboarding to close, with real-time intelligence for every deal.

Letter AI connects seller readiness with real-time deal intelligence in one AI-native platform. Letter goes beyond traditional enablement to help sellers take the right action in active deals, so they win more deals, win bigger deals, and shorten sales cycles.

Comparison of Letter AI versus Seismic / Highspot
Criterion Letter AI Seismic / Highspot
AI-native platform Built AI-native and unified from day one. One system connects content, coaching, and deal intelligence. Legacy platforms and products being unified, with AI bolted on.
Speed & agility Built for speed, end to end. Launch, adapt, and innovate as fast as your business changes. Integration adds complexity. Combining two large platforms slows the pace of innovation.
In-deal execution Live in the deal, not just before it. Real-time, contextual guidance helps sellers know what to do next. Built for traditional enablement. Designed to prepare sellers rather than guide them through active deals.
Revenue impact Connect readiness to revenue. Tie seller readiness, buyer engagement, and execution to pipeline outcomes. Prove activity, not impact. Focus on completion metrics, with less visibility into revenue outcomes.
