The London- and Budapest-based company’s technology is designed to help large organizations understand and renew complex legacy software while keeping source code and data within the customer’s own IT environment.
The investment round was led by European venture capital investor VentureFriends. Portfolion, part of OTP Group and the largest investor in Kodesage’s previous funding round, also participated, alongside several angel investors, including xAI co-founder Christian Szegedy and German World Cup-winning footballer Mario Götze.
Kodesage was founded in 2024 by technology entrepreneurs Gergely Dombi, Miklós Szurdi and György Szilágyi.
The idea grew out of the earlier experience of Dombi and Szurdi, who built Sonrisa, a software development and consulting company with more than 300 employees specializing in the modernization of legacy systems. Their third co-founder, Szilágyi, previously achieved a successful exit with encrypted cloud storage company Tresorit.
The founders set out to make software modernization more cost-effective and predictable, while shortening projects that previously took years to complete to a matter of months.
Kodesage aims to simplify how companies understand and use information locked inside complex legacy software environments.
The platform extracts information from source code, databases and documentation, using it to create a continuously updated knowledge base. This can help organizations maintain and migrate business-critical software with significantly lower risk and cost.
Kodesage’s platform performs automated discovery across complex codebases, generates up-to-date documentation, supports migration projects, automates test generation and provides AI-based operational support.
The technology primarily targets regulated industries such as banking, insurance, energy and government, where critical processes often continue to run on systems written decades ago.
These systems may be stable enough to support essential business operations, but even minor changes can be complex, expensive and time-consuming. The challenge is becoming more pressing as engineers with deep knowledge of the systems retire and the pool of experts familiar with older technologies continues to shrink.
“Countless companies around the world struggle with maintaining and renewing on-premise legacy software systems. Starting with Oracle applications, Kodesage helps companies understand, maintain and modernize complex, undocumented legacy codebases. As a result, they can achieve significant time and cost savings while reducing their dependence on retiring experts. Gergely, György and Miklós have deep experience in this field, and we are delighted to support them on this journey,” said Apostolos Apostolakis, founding partner at VentureFriends.
A key element of the Kodesage solution is that it operates entirely within the customer’s own system, meaning source code and data never leave the organization’s control.
This is particularly important in regulated sectors, where valuable business knowledge is often embedded in databases and software code developed over decades. Strict data protection requirements may prevent companies from connecting these systems to popular cloud-based AI services.
By operating in a local environment, Kodesage can be used with sensitive information while offering costs that are independent of usage levels, the company says.
The platform supports a broad range of modern and legacy technology environments, including a solution specifically designed to support the modernization of Oracle Forms applications.
Kodesage plans to use the fresh capital to accelerate its expansion in the United States and Europe, while continuing to grow its engineering and product teams.
The funding also supports the company’s longer-term ambition to create self-healing enterprise software capable of detecting and correcting its own errors over time without direct human intervention.
“Supporting modernization is not the end goal; it is merely a step toward self-sustaining systems. Our vision is to realize self-healing enterprise applications: systems that continuously learn, test and carry out bug fixes, while engineers only supervise the results instead of diagnosing problems and writing code from scratch. For regulated companies whose support teams have been under increasing pressure for years, this is where the greatest value lies,” said Gergely Dombi, co-founder and CEO of Kodesage.
