Recho secures KDDI Open Innovation Fund V backing for voice AI contact centres

What's the deal? Tokyo-based startup RechoDealroom has a profile for this one. Try Dealroom → has secured investment from KDDIDealroom has a profile for this one. Try Dealroom → Open Innovation Fund V (KOIF V), managed by venture firm Global Brain. The exact funding amount was not disclosed. Recho builds AI-native contact centre solutions for enterprise clients, developing its own speech synthesis, speech recognition, and dialogue control technology from scratch.

Founded in 2021, the company already counts major financial institutions among its clients. In a proof of concept with SBI Shinsei BankDealroom has a profile for this one. Try Dealroom → covering roughly 3,000 interactions, Recho's voice AI achieved a dialogue accuracy rate above 99%.

Why now? Japan faces a severe labour shortage in its contact centre industry, making AI-driven automation not just a nice-to-have but an operational necessity. Enterprises need solutions that maintain service quality while reducing headcount pressure.

Recho plans to use the capital to expand its engineering team and strengthen its end-to-end pipeline from R&D to deployment. The goal: faster rollouts and higher accuracy across industries.

What could go wrong? Voice AI in high-stakes settings — especially financial services — carries real risk. A 99% accuracy rate sounds impressive, but in a contact centre handling thousands of daily calls, even a 1% error rate can mean dozens of mishandled interactions. Regulatory scrutiny around AI in customer-facing roles is also intensifying in Japan and globally.

Recho's approach of building core technology in-house gives it more control but also means heavier R&D costs and a longer road to scale compared to startups that integrate third-party models.

The signal: KDDI's corporate venture arm backing an early-growth voice AI startup underscores how Japan's telecoms are positioning themselves as enablers — not just carriers — in the enterprise AI stack. Recho's in-house approach to speech synthesis and recognition, rather than relying on third-party models, makes it a natural fit for a fund explicitly seeking startups that could seed new KDDI business lines. With Japan's contact centre workforce shrinking and Recho already deployed at major financial institutions, the commercial case is less speculative than typical deep tech bets.
