Israeli AI startup Wonderful has raised $550 million in a Series C funding round, valuing the company at $5 billion, equivalent to more than CZK 100 billion. The company, which builds AI agents and an operating system for deploying them across large enterprises, reached the milestone just 18 months after its launch. One of its earliest backers was United Founders, the pan-European venture capital fund backed by Rockaway Capital.
Wonderful has emerged as one of Europe’s fastest-growing AI startups. Founded in early 2025, the company focuses on bringing AI agents into the day-to-day operations of large organizations. Its platform helps enterprises automate end-to-end workflows, build and deploy AI-native applications, and orchestrate AI agents across different teams, functions and markets.
Wonderful more than doubles its valuation in six months
The latest Series C round was led by Insight Partners, with Salesforce joining as a new investor. Existing backers Index Ventures, IVP, Bessemer Venture Partners, Vine Ventures and 9Yards Capital also participated. The round marks another sharp acceleration in Wonderful’s growth. In just six months, the company has more than doubled its valuation. The pace is exceptional even by the standards of the current AI investment boom. Following its seed round, Wonderful raised $100 million in Series A funding. In March 2026, it secured a $150 million Series B at a $2 billion valuation. Less than six months later, the latest Series C round has pushed its valuation to $5 billion.
United Founders, the pan-European early-stage venture capital fund backed by Rockaway Capital, was part of the story from the outset. The fund invested in Wonderful at seed stage, well before the company began attracting hundreds of millions of dollars from some of the world’s largest technology investors and venture capital firms. The investment, however, almost never happened.
In early 2025, Wonderful founder Bar Winkler reached out to Vít Horký, co-founder and General Partner at United Founders, asking for a short meeting. Horký later recalled at the Backstage by Rockaway conference at Prague’s Žofín Palace that he initially failed to respond for several weeks — and could easily have missed what would become one of the fund’s standout investments. When they finally connected on a video call, Winkler reportedly challenged him not only over the weeks of silence, but also for joining a few minutes late. “Where have you been for the last three weeks? I don’t have time to waste time,” Winkler told him. “At first, my ego took a hit. Then I realized he was right. If anyone is going to capture a massive share of the market, it’s a founder for whom ‘no’ is not an answer,” Horký later said.
Why Wonderful is betting on AI agents
What immediately stood out to Horký was not simply the scale of the generative AI opportunity, but Wonderful’s approach to bringing the technology into real-world enterprise operations. The investment thesis was straightforward: businesses do not need another AI model. They need AI agents that can actually work inside their organizations — across different markets, languages and regulatory environments — while adapting to local business requirements. This implementation gap is becoming one of the defining challenges of enterprise AI adoption. Large companies may have access to increasingly powerful models, but turning those models into secure, scalable and measurable business processes is a different challenge altogether.
Wonderful aims to bridge that gap with a platform designed to manage an enterprise-wide ecosystem of AI applications and agents. Rather than treating individual AI tools as isolated experiments, the company provides infrastructure through which agents can be deployed, coordinated, governed and monitored across the organization.
From 500 employees to a planned 1,000 within a year
Wonderful now operates in more than 35 countries across Europe, the Middle East, Asia-Pacific and Latin America. Its rapidly expanding workforce offers another indication of the pace at which the company is scaling. By mid-year, Wonderful had more than 500 employees and was targeting a workforce of 1,000 by the end of the year.
“Six months ago, we had dozens of people. Today, there are 500 of us, and by the end of the year there will be a thousand across three continents. A journey that used to take decades can now happen in a year or two,” said Karel Nohejl, General Manager of Wonderful AI for the Czech Republic and Slovakia, during an appearance at Backstage by Rockaway. According to Nohejl, large corporations are now entering a new phase of AI adoption: the era of agents. Customers are already using Wonderful to automate workflows, develop and deploy AI-native applications, and orchestrate agents across multiple parts of their businesses.
The challenge is not simply giving employees access to more AI. Companies also need to retain control over what individual agents can access, what actions they are allowed to perform and how they interact with sensitive corporate data. “Companies don’t have a system for managing this. If they leave it uncontrolled, sensitive corporate data can be compromised. Wonderful provides an environment for agents that is centrally managed and monitored,” Nohejl explained. That ability to turn rapidly evolving AI capabilities into a secure and manageable enterprise infrastructure is central to Wonderful’s proposition — and one of the reasons investors are assigning the company such a high valuation.
From an early seed investment by United Founders to a $5 billion valuation, Wonderful has completed that journey in roughly 18 months.
