Israel-based Wonderful Ltd., a startup that builds enterprise-ready artificial intelligence agents, today announced it has raised $100 million in an early-stage funding round led by Index Ventures.

New investors Insight Partners and IVP joined the Series A round alongside existing backers Bessemer Venture Partners and Vine Ventures. The raise comes just four months after the company’s $34 million seed round.

Founded just this year, Wonderful builds multilingual AI agents designed to interact with customers across languages, cultural norms and regulatory environments. Its agents integrate directly with enterprise systems to handle domain-specific use cases, allowing them to understand industry context and respond appropriately.

The company said its agents already handle tens of thousands of complex interactions a day, including resolving billing disputes, updating account details, diagnosing issues and scheduling appointments. Internal statistics show resolution rates above 80%, with a vast majority of the issues resolved without intervention from human support.

Wonderful’s agents support customer interactions across voice, chat, and email, and the company’s initial focus on customer support is rapidly broadening. Enterprises are now experimenting with applications such as employee training, sales assistance, regulatory compliance, internal information technology support and onboarding.

Wonderful is entering a crowded field of enterprise AI agent developers that includes Kore.AI Inc., PolyAI Ltd. and Cognigy GmbH, all of which offer multilingual AI assistance for customer service and workflow automation. The company sets itself apart, however, because many of these companies began as English-first and expanded globally through translation and localization.

By contrast, Wonderful was designed from day one for non-English-speaking markets, with agents tuned for local culture and industry context. The company is betting that this multilingual-first approach will establish it with enterprises seeking AI agents that can truly “speak their language,” both literally and operationally.

Since the last round, Wonderful has expanded its AI platform rapidly into new countries, including Italy, Switzerland, the Netherlands, Greece, Poland, Romania, the Baltics, the Adriatics and the United Arab Emirates.

“The scale of demand were seeing from enterprises is enormous,” founder and Chief Executive Bar Winker told Reuters.

Winker added that the new funding will accelerate hiring of local teams and continued investment in the company’s agentic AI capabilities, supporting faster international rollout.

The company is also in preparations to launch in Germany, Austria, the Nordics and Portugal in 2025, with Asia-Pacific expansion planned for early 2026.

“Wonderful has moved from concept to global scale in less than a year, which is extraordinary by any measure,” Hannah Seal, partner at Index Ventures said. “They’re proving that enterprises don’t just want AI agents; they want ones that work in every market, in every language.”
