NT-Layer provides "TLN-ENGINE," a fully automated next-generation AI SaaS specifically designed for sales enablement and negotiation support. Unlike traditional sales AI tools that merely summarize meetings or offer basic communication tips (which are easily commoditized by the evolution of general LLMs), TLN-ENGINE focuses exclusively on the critical "latter half" of negotiations. It is the world's first SaaS to fully implement the "tacit knowledge" of top-tier negotiators. When a deal stalls (e.g., "We will think about it"), the system analyzes the buyer's hidden psychological barriers and automatically generates practical, non-obvious next actions and scripts to close the deal. Because its core architecture relies on a proprietary structured memory layer of expert tacit knowledge—rather than just the generic training data of LLMs—TLN-ENGINE is future-proof and resistant to obsolescence caused by AI advancements. Furthermore, this unique architecture of controlling LLMs through tacit knowledge layers offers high scalability, with the potential for horizontal expansion into other expert domains such as consulting and counseling.
