Kodesage has raised USD $6.6 million in seed funding in a round led by VentureFriends.
PortfoLion, which led the company's pre-seed financing, also participated, alongside angel investors including Mario Götze and Christian Szegedy, co-founder of xAI.
Founded in 2024, Kodesage develops an on-premise artificial intelligence platform to help large organisations understand, document and update legacy software systems. It is targeting regulated sectors including banking, insurance, energy, transport, telecoms and the public sector, where core operations often still rely on software built decades ago.
Kodesage was founded by Gergely Dombi, Miklos Szurdi and Gyorgy Szilagyi. Dombi and Szurdi previously built a software consultancy with more than 300 staff focused on legacy modernisation projects, while Szilagyi was a co-founder of Tresorit.
Its software extracts information from code and documentation to create what Kodesage calls a live knowledge layer, giving technology teams a clearer view of older systems before starting maintenance or migration work. The platform runs inside a customer's own environment, whether on-premise, in a virtual private cloud or in an air-gapped setup.
That approach reflects a practical constraint in heavily regulated industries. Many of the systems Kodesage targets store critical business logic in databases, stored procedures, schemas and configuration layers that companies are unwilling or unable to expose to public cloud services.
Legacy burden
The company focuses on software stacks such as Oracle Forms, PL/SQL, COBOL, PowerBuilder and RPG, which remain in use across large enterprises despite the age of the underlying technology. It has also developed a dedicated Oracle Forms modernisation kit aimed at a segment it argues is underserved by broader software migration tools.
Businesses in these sectors often face a shrinking pool of specialists able to work on such systems as experienced engineers retire and historical knowledge is lost. That can make even routine changes costly and slow, particularly when the software underpins critical operations.
Kodesage says its platform automatically analyses codebases, produces and maintains documentation, supports migration through context-aware code conversion, generates tests and assists with production support using AI tools. It argues this can reduce the operational risk of changing old but essential systems.
In regulated markets, the challenge is not simply replacing old software with new tools. Legacy and newer systems often run side by side for long periods, creating ongoing support demands as businesses try to preserve continuity and meet compliance requirements.
"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," said Gergely Dombi, Chief Executive Officer of Kodesage.
Investor backing
The presence of Götze and Szegedy in the investor group gives the round a higher profile, though investors' strategic case centres on the market for modernising software that cannot easily be moved into cloud-based AI systems.
VentureFriends said Kodesage's initial focus on Oracle applications gives it an entry point into a large installed base of hard-to-maintain software in major organisations. It also highlighted the founders' experience delivering modernisation projects before launching the product.
"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," said Apostolos Apostolakis, Founding Partner at VentureFriends.
The new capital will support Kodesage's expansion in the United States and Europe, as well as further hiring in engineering and product teams.
