Wonderful raises $100M Series A just four months after $34M Seed, as AI agent boom accelerates
The fast-moving AI startup is already operating in 10 countries, automating customer service and sales for global clients.
Just months after its emergence from stealth, Wonderful, a company developing AI-powered agents for enterprise use, has raised $100 million in a Series A round led by Index Ventures, with participation from Insight Partners, IVP, and existing backers Bessemer Venture Partners and Vine Ventures.

The new funding, coming only four months after a $34 million seed round, underscores investor confidence in Wonderful’s rapid ascent and its approach to bringing AI agents into real-world enterprise production environments.
“We’ve launched operations in 10 countries and recruited senior executives for all key roles,” CEO and co-founder Bar Winkler told Calcalist. “The opportunity to raise additional capital allows us to accelerate expansion and move faster. Our clients use our agents for call transcription, sales optimization, training, and procurement processes. The know-how around building effective AI agents is still very new, so we’re working closely with clients to design their agents, and eventually, we’ll transfer that work to them.”
Winkler emphasized that Wonderful’s agents are designed to enhance efficiency rather than replace human workers. “Using our agents today streamlines workflows but doesn’t lead to layoffs or staff reductions,” he said. “While our agents can replace people, organizations mainly want to maintain service quality. What’s changing is what people do, not whether they’re needed. Customers get more value and higher-quality service across countless interactions.”
According to Winkler, the rapid evolution of AI has transformed how organizations think about technology adoption: “Companies now understand that AI is real and capable of solving complex problems. Many begin by improving customer service, a universal pain point where AI can make an immediate impact. Over time, we’ll see AI extend into other functions, and it’s hard to predict how that will reshape roles within organizations.”

Founded in early 2025, Wonderful has moved at unusual speed for a young enterprise software company. Since its last funding round, it has expanded into Italy, Switzerland, the Netherlands, Greece, Poland, Romania, the Baltics, the Adriatics, and the UAE, with plans to enter Germany, Austria, the Nordics, and Portugal next year, and Asia-Pacific in early 2026.
Enterprises across these markets are already deploying Wonderful’s AI platform to automate customer-facing interactions across voice, chat, and email, handling tens of thousands of complex exchanges daily. The company reports resolution rates above 80%, meaning the vast majority of issues, from billing disputes to appointment scheduling, are resolved without human intervention.
Each AI agent is designed to adapt to local language, cultural norms, and regulatory environments, while integrating deeply into a customer’s internal systems. This local-first approach, coupled with centralized AI infrastructure, has been key to its rapid adoption.
“To provide excellent service, agents must operate in the local language and connect to local systems and work culture. Language is a defining part of every market,” Winkler noted.
Wonderful currently employs 120 people across development and go-to-market functions and expects further growth by year-end. The company maintains its core development team of 40 engineers in Israel, while local implementation and operations teams are being built across new markets.
Winkler previously founded Approve.com, a platform for automated payment management for businesses, which was sold to Tipalti in 2021. Co-founder Roey Lalzar (CTO) previously founded Kaps, an AI-based localization platform.
