Kodesage, the on-premise AI platform that helps enterprises understand, document and modernise critical legacy software systems, has raised a $6.6 million Seed round led by VentureFriends. Pre-Seed lead investor Portfolion joined the round, alongside notable angel investors including Christian Szegedy, co-founder of Elon Musk’s xAI, and Mario Götze, the German footballer and World Cup winner.
Founded in 2024 by enterprise software entrepreneurs Gergely Dombi, Miklos Szurdi and Gyorgy Szilagyi, Kodesage is transforming how enterprises understand and use the information buried inside complex legacy software stacks. Its platform extracts information from code and documentation to create a live knowledge layer that enables teams to maintain and migrate mission-critical software with less risk. The platform performs automated deep discovery of complex codebases, generates and maintains living documentation, supports migration with context-aware code conversion, automates test generation and enables AI-powered production support.
The idea was sparked by Dombi and Szurdi’s experience building a 300+ person software consultancy that specialised in modernising legacy systems. These projects were often slow and lengthy, as they depended on fragmented knowledge and a small number of specialists. Together with Szilagyi, an exited co-founder of Tresorit, they set out to make software modernisation scalable and repeatable, compressing projects that would previously take years into months.
The Kodesage technology is built for highly regulated industries such as banking, insurance, energy, transportation, telecoms and the public sector, where mission-critical operations continue to run on software built decades ago. While these systems are stable enough to be trusted with core business processes, changing them is complex, expensive and time-consuming – particularly as the original engineers retire and the pool of expertise surrounding these technologies shrinks.
The platform has also been designed to overcome data residency and sovereignty challenges. Unlike modern greenfield software, which is more easily updated using AI coding tools, legacy systems – like Oracle Forms, PL/SQL, COBOL, PowerBuilder and RPG – hold critical business logic outside of source code in stored procedures, database schemas and configuration. Much of it sits behind databases that regulated enterprises cannot expose to cloud-based AI services. For organisations bound by strict data residency, sovereignty and compliance requirements, this puts the most valuable institutional knowledge out of reach.
Kodesage solves this by operating entirely inside the customer environment – on-premise, in a virtual private cloud or fully air-gapped where required – so that source code, schemas and database content never leave the organisation’s control. This architecture also gives enterprises data sovereignty, end-to-end security and predictable, transparent infrastructure costs decoupled from per-token consumption.
Kodesage supports a broad range of modern and legacy stacks, with a dedicated Oracle Forms modernisation kit: a stack that is still widely used across regulated industries, but is poorly served by mainstream modernisation tooling.
The new funding will accelerate Kodesage’s go-to-market in the United States and Europe – and will power continued investment in the organisation’s engineering and product teams to deliver on Kodesage’s vision of self-healing enterprise applications.
Gergely Dombi, co-founder & CEO of Kodesage, said:
“Software modernisation is rarely clean cut. In regulated environments, legacy and new systems often coexist for years, whilst the support burden grows as institutional knowledge thins out. This is a multi-trillion-dollar drag on enterprise IT. Kodesage’s living knowledge layer helps teams modernise legacy systems faster, resolve incidents and reduce repeat issues through powerful AI-assisted support.
“Our vision is self-healing enterprise applications: systems that can continuously learn, propose, test, and validate fixes, with engineers guiding outcomes rather than diagnosing problems and writing code from scratch. For regulated enterprises whose support teams have been under growing operational pressure for years, this is where the deepest value lies.”
Apostolos Apostolakis, Founding Partner of VentureFriends, said:
“There are numerous enterprises globally struggling to maintain and upgrade legacy software systems that reside on-premise. Starting with Oracle applications, Kodesage can help companies understand, maintain, and modernise complex, undocumented legacy codebases. As a result, they save them time and cost while cutting their dependence on retiring experts. Gergely, Gyorgy and Miklos have deep experience in the space, and we couldn’t be more excited to back them in their journey.”
