Oakley Capital takes majority stake in Graphwise in one of Bulgaria’s largest software exits

Oakley Capital has agreed to buy a majority stake in Graphwise, the enterprise AI data platforms company that now sits among the biggest software exits Bulgaria has seen. The price was not disclosed, but the deal is being described as one of the most significant exits in the regional enterprise AI sector as well.

Graphwise itself is a fresh merge of older names. It was created in 2024 from Ontotext, founded in Sofia in 2000, and Vienna-based Semantic Web Company, founded in 2004. That gives the company a long runway behind a newly assembled corporate shell, which is often how serious software roll-ups look before they start sounding fashionable.

The business has been growing fast by the sound of it. Graphwise says it has posted historical organic ARR growth of more than 30% a year, helped by the AI tailwind, and it now provides AI data infrastructure to more than 200 international blue-chip clients across financial services, pharmaceuticals and the public sector. Its core territory is RDF knowledge graphs and semantic layer technology — the unglamorous scaffolding under a lot of AI talk.

Portfolion Capital Partners has exited its stake in the company through the transaction. It had bought into the business in 2022 as part of an investment consortium, and its deputy CEO Jenő Nieder framed the sale as proof that domestic and regional private equity can win in deep tech without chasing short-term AI hypes. Oakley, meanwhile, says it wants to speed up international expansion and add more acquisitions with management.
