What the company does
Knowledge Work was established in March 2020 and began business on 1 April 2020. Its customers are mainly large enterprises, including NTT Docomo Business, Mizuho Bank and Nissin Foods, with deployments that reach several thousand users, according to the release.
It sells three lines of products. The Sales AX Consulting series builds and runs custom AI agents for a client's sales work. The Sales AI Product series offers standard agents for common sales tasks. The new Sales AI Agent OS series is a foundation for building agents that use a company's own data and strategy.
The operating system has four layers. An ontology layer links each company's sales data in its sales context, a strategy layer takes in its sales strategy, an agent layer builds, manages and analyses agents, and an interface layer gives users access.
The team
Koji Asano is chief executive, Hazumu Yamazaki is chief AI officer and Maya Kawanaka is chief technology officer. The release names no founders and gives no headcount.
Joe Konno, a managing partner at Globis Capital Partners, said Asano's vision and strategy from the founding days have not wavered and that steady progress is being made towards realising them.
Yamazaki described the company as a one-of-a-kind AI company providing consulting, products and the agent operating system end to end for sales.
What the money is for
The company plans capital and business alliances with leading companies across industries and strategic partnerships through corporate venture funds. The Bridge reported that it intends to combine those partners' customer bases and solutions with its AI technology and sales enablement know-how to speed up delivery of sales AI agents.
Kawanaka said the company will accelerate technology development for the Sales AI Agent OS. The release does not break down spending further.
