What's the endgame? nocall builds "nocall.ai," a generative-AI phone service that automates business calls. It plans to use the money for hiring and product development, chasing a mission to "make all business communication AI-driven."

Why now? The startup launched its service in late 2023 and has since landed enterprise customers across the automotive, finance, staffing, and IT sectors. Investors framed the raise around Japan's shrinking workforce and the difficulty of building natural-sounding Japanese voice AI — a barrier that has slowed adoption compared with the US.

Does it work? At customer MOTADealroom has a profile for this one. Try Dealroom →, automating appointment-confirmation calls cut same-day cancellations from about 15% to 5.7%, preventing roughly ¥750,000 in daily lost opportunity. At Racoon FinancialDealroom has a profile for this one. Try Dealroom →, replacing older robocalls with nocall.ai raised payment-commitment rates in debt collection three- to fourfold.

JAFCO said it was drawn to nocall taking on "a difficult, large market head-on," pointing to a phone market it described as worth trillions of yen. Coreline noted nocall recently began offering its phone agent via API, calling it a company with "the potential to rebuild Japan's phone infrastructure." (translated from Japanese)

The signal: AI voice agents are among the fastest-growing software categories globally, but Japanese-language nuance — intonation, pauses, and high customer service expectations — has kept most local phone work human. nocall's round is a bet that a homegrown model, rather than imported voice tech, can finally crack it.
