Israeli AI agent startup Wonderful has raised $100 million in a Series A round led by Index Ventures, with participation from Insight Partners, IVP, Bessemer, and Vine Ventures.

The large round, in a market already crowded with AI agent startups, suggests Wonderful has convinced top tier investors it’s not just another GPT wrapper, but a company building the infrastructure and orchestration that could scale if multi-agent systems take off.  

The round brings Wonderful’s total funding to $134 million just four months after the startup came out of stealth with a seed round and a promise to help enterprises deploy customer-facing AI agents across voice, chat, and email in every market and every language. The startup says it tailors the platform to each market it serves, fine-tuning for language, cultural norms, and regulatory environments, and even organizes local teams to manage deployment.  

That approach has led to rapid growth for the young startup, which claims its AI agents are already managing tens of thousands of customer requests daily with an 80% resolve rate. Since launching, Wonderful has expanded to Italy, Switzerland, the Netherlands, Greece, Poland, Romania, the Baltics, the Adriatics and the UAE. 

With its fresh funding, Wonderful intends to launch in Germany, Austria, the Nordics and Portugal in 2025, and plans to expand in the Asia-Pacific region in early 2026. But the company doesn’t intend to stop with customer support agents.

Since its system plugs deeply into an enterprise customer’s existing software and can be tailored for each market, the startup says it will be able to give agents the capabilities to perform new tasks with minimal extra effort. It is currently exploring areas like employee training, sales enablement, regulatory compliance, internal IT support, and onboarding, the company said. 

“The promise of AI agents is clear, but putting that into practice, and critically, into production, is a huge challenge,” Bar Winkler, CEO and co-founder of Wonderful, said in a statement. “It requires marrying best-in-class technology together with flawless delivery, on the ground with customers. That’s been our approach with Wonderful, and it’s what has driven the accelerated adoption we’ve seen across markets in the last few months.” 

Customer-facing AI agents are emerging as the first real beachhead for the technology, and investors were likely attracted by Wonderful’s focus here. These use cases help enterprises cut costs by augmenting or replacing human support staff, and they integrate readily into existing call centre infrastructure. Crucially, they also carry less risk than having an AI make internal decisions autonomously — a use case that most enterprises aren’t ready to adopt at scale yet.  

Index Ventures partner Hannah Seal pointed to Wonderful’s ability to “[move] from concept to global scale in less than a year” as a source of confidence for investors. The company’s true edge, she said, is its ability to deploy agents for global enterprises that function across every market and language. 

Jeff Horing, co-founder and managing director at Insight Partners, said the adoption Wonderful is seeing across industries shows “just how valuable culturally fluent agents can be.”
