EBRD and partners exit Graphwise investment in Bulgaria

The European Bank for Reconstruction and Development (EBRD), Integral Capital Group, PortfoLion Capital Partners and Carpathian Partners have signed a binding agreement to sell their stakes in Graphwise to Oakley Capital, according to a press release by the EBRD on 24 August 2026. Oakley Capital will acquire a majority stake in Graphwise and partner with the company’s founders and management team to support its continued expansion. The transaction marks a successful exit for the EBRD from its 2023 investment in Ontotext, the Bulgarian company that later became Graphwise.

The EBRD invested in Ontotext in 2023, following Integral Capital Group’s acquisition of a controlling stake in the company in 2022. Ontotext subsequently merged with Vienna-based Semantic Web Company to create Graphwise, a provider of knowledge graph and semantic technologies. Founded in Sofia in 2000, Ontotext was an early pioneer in the field of knowledge graph technology, helping enterprises to manage and derive value from large volumes of data.

The Bank supported the merger and the subsequent integration process, contributing to the creation of Graphwise and helping to position the business for its next phase of growth. Integral Capital Group led the company’s development throughout the investment period. The EBRD played an active role as an institutional shareholder through board-level representation and the strengthening of governance practices. The exit reflects the company’s strong growth and development over the investment period.

Today, Graphwise has established itself as a leading provider of software that helps enterprises to organize, connect and make better use of complex data, serving more than 200 business customers globally. By improving the way in which information is structured and accessed, its technology enables businesses to generate more accurate insights and deploy artificial intelligence solutions more effectively. The sale also demonstrates the role that EBRD equity investments can play in helping innovative companies to scale up, strengthen governance and attract new investors.

The EBRD is a leading institutional investor in Bulgaria. It has deployed almost €5.2 billion in the country to date across 327 projects, through a combination of loans and equity investments. The successful sale to Oakley Capital is set to support Graphwise’s continued expansion under new ownership.
