Testing the Digital World: Mozark Secures $40M to Scale Global Experience Measurement

The new funding, led by IFC and RMB Capitalworks, will support global expansion and strengthen real-world digital performance testing.

Mozark, a Singapore-based company specializing in digital experience testing and measurement, says its platform is designed to address this challenge—and investors appear to share that view. The company has announced a $40 million Series B funding round aimed at expanding its international presence and enhancing its testing infrastructure. The round was led by the International Finance Corporation (IFC), part of the World Bank Group, and RMB Capitalworks, with existing backer Kalaari Capital also participating.

Mozark said the new capital will support its next phase of global expansion and potential strategic acquisitions as demand grows for reliable digital performance across devices, networks, and geographic markets. The modern digital economy increasingly depends on services that must perform consistently across complex environments. From mobile banking and healthcare systems to enterprise platforms and public services, users expect seamless digital interactions regardless of their location or device.

However, real-world performance often varies widely. Applications may behave differently depending on network quality, device capability, data center latency, or regional infrastructure conditions. As AI-powered services become more common, these technical variations can significantly affect reliability and user experience. Mozark’s platform focuses on measuring how digital services perform under real-world conditions. Instead of relying solely on simulated environments, the company runs automated tests on real devices connected to real networks across different regions. The goal is to identify performance issues before they affect end users.

Mozark’s Approach to Real-World Testing

Mozark’s technology uses an AI-assisted platform that simulates real user journeys across applications and infrastructure environments. These tests generate telemetry data that helps organizations detect performance problems across the entire technology stack—from the application layer to underlying networks and infrastructure.

The system can identify the root causes of service disruptions, including issues related to:

• Network performance
• Data center latency
• Device compatibility
• Infrastructure reliability

By identifying these problems early, companies can fix them before they affect customers.

The approach is increasingly relevant as digital systems become more complex and distributed across cloud platforms, telecom networks, and edge infrastructure.

One of Mozark’s central arguments is that the digital economy still suffers from what it describes as a “digital quality divide.”

While internet access has expanded globally, the quality and reliability of digital services remain uneven. In many emerging markets, inconsistent infrastructure can lead to unreliable app performance, slow services, or system outages.

These problems can have significant real-world consequences.

If digital payment systems fail, businesses cannot process transactions. If healthcare or government platforms perform poorly, essential services may become inaccessible. Even small disruptions can reduce trust in digital systems and slow broader adoption.

Mozark positions its platform as a tool to help organizations ensure “digital experience equity”—consistent digital service performance regardless of geography, device, or network conditions.

Investors see a role in strengthening digital infrastructure

The company already works with a diverse range of customers across industries. According to Mozark, its platform currently supports more than 50 enterprise and government clients across 20 countries, including telecom operators, financial institutions, regulators, and digital-native companies.

Its testing infrastructure operates on thousands of live devices worldwide and has executed more than 25 million tests to date. These tests generate benchmarking data and analytics that help organizations evaluate how their digital services perform across different environments.

This kind of testing infrastructure has become increasingly important for companies that operate across multiple global markets where network conditions and infrastructure vary widely.

Mozark’s investors say the company’s technology could play an important role in improving digital infrastructure performance, particularly in emerging markets.

“Reliable digital infrastructure is critical to productivity, inclusion, and growth in emerging markets,” said Farid Fezoua, Director for Equity, Funds and Venture Capital at IFC. “By strengthening the performance and reliability of the applications and networks that underpin essential services, our investment in Mozark will support innovation, skilled job creation, and broader access to digital services.”

For development finance institutions like IFC, investments in digital infrastructure technologies are increasingly viewed as a way to support economic development and digital inclusion.

Meanwhile, RMB Capitalworks highlighted the growing importance of testing and observability as digital systems become more complex.

“We are very excited to join Mozark’s journey,” said Robert Oudhof, Director of RMB Capitalworks. “The company’s agentic AI-led platform addresses critical challenges for enterprises and regulators in the app testing and observability domain globally.”

Preparing for the next generation of digital interaction

Mozark’s leadership argues that testing is becoming a major bottleneck in modern software development.

While AI has significantly accelerated coding and software development, validating performance in real-world environments still depends on physical infrastructure such as devices, networks, and distributed computing environments.

“AI is accelerating digital services everywhere, but experience quality remains disparate and unreliable,” said Kartik Raja and Fabien Renaudineau, founders and co-CEOs of Mozark. “Mozark enables organizations to measure and improve service performance in real-world conditions, detect gaps early, and ensure reliable digital experiences at scale.”

Mozark’s product roadmap also includes expanding its agent-to-agent communication testing platform, which the company says will support emerging AI-driven digital interactions.

According to Chandra Ramamoorthy, founder and chief product officer of Mozark, the platform will allow organizations to validate how automated AI systems interact with each other in real-world digital environments.

How Mozark plans to use the funding

The company said the Series B funding will support several strategic initiatives, including:

• Expanding real-world testing across applications, networks, and AI infrastructure
• Accelerating growth in priority markets such as the United States and the Global South
• Investing in advanced testing infrastructure and research and development

Existing investor Kalaari Capital also reaffirmed its confidence in the company’s long-term strategy.

“We have been long-term partners to Mozark and continue to have strong conviction in the company’s strategy and execution,” said Rajesh Raju, managing director at Kalaari Capital.

The bigger picture

Mozark’s funding round reflects a broader shift in the digital ecosystem. As digital services become deeply integrated into economic activity—from payments and banking to healthcare and public services—the reliability of those services becomes critical infrastructure in its own right.

Ensuring that applications work consistently across diverse real-world environments is no longer just a technical issue. It is increasingly tied to economic participation, digital inclusion, and user trust. For Mozark, the challenge—and opportunity—lies in building the measurement layer that allows organizations to understand how digital systems truly perform outside controlled lab environments.

If the company can scale its testing infrastructure globally, it could become a key player in ensuring that the rapidly expanding digital economy actually works for users everywhere.
