About SellScale

SellScale is an Agentic AI company.

Problem: Businesses big and small rely on “outbound sales” to grow revenue. Most methods today are outdated or rely on spray-and-pray.

Opportunity: With the advent of recent tech like like agentic AI, large language models, vector databases, and more - future sales teams will work with machine to grow their businesses.

Timing: Right now, we are in a massive AI gold rush. The agents we’re building leverage PhD-level thinking paired with state-of-the-art GTM tools (prospecting, web intent, sequencing, etc) - to fundamentally change how companies approach their growth.
