HedgeCo.Net — Oakley Capital said on August 19 that Fund VI has agreed to acquire a majority stake in Graphwise, a knowledge-graph and semantic-data platform used as enterprise AI infrastructure. Graphwise’s own PR Newswire release the same day confirmed the majority is coming from an investment consortium led by Integral Capital Group, including PortfoLion Capital Partners, Carpathian Partners, and the European Bank for Reconstruction and Development. Financial terms of the transaction are not disclosed. Founders and management remain in place. Oakley will work with President and co-founder Atanas Kiryakov on commercial expansion, international footprint, and selective acquisitions.
Graphwise was formed in 2024 from the merger of Sofia-based Ontotext, founded in 2000, and Vienna’s Semantic Web Company, founded in 2004. Both the Oakley note and the company release put the customer count at more than 200 blue-chip names and organic ARR growth at over 30% a year. That 30% is the companies’ own growth claim. It is not a third-party audit and it is not a forecast. The product is RDF knowledge-graph software — a semantic layer meant to give large language models a verified set of facts to retrieve from, pitched at regulated, data-heavy sectors.
A mid-market European software majority with no printed check is the allocator fact. Integral’s consortium is selling control. Oakley is buying it through Fund VI and talking bolt-ons in a fragmented market. There is no disclosed enterprise value, no premium, and no close date in either release. Until a close is announced, Graphwise is a signed majority agreement, not a Fund VI portfolio company.
For private-equity LPs the diligence is the exit, not the AI label. A founder-led knowledge-graph business with more than 200 customers and a self-reported 30% organic ARR clip is the operating book. The seller group includes a development bank. Neither primary release printed a price. Anyone marking a European software takeout off this announcement is inventing a number the sponsors did not print.
The second-order read is how European mid-market PE is paying up for AI-adjacent data infrastructure without putting a valuation on the tape. Allocators should keep the majority, the Integral-led seller group, and the 200-customer / 30% ARR claims in the releases, and wait for a close. The scarce object is a disclosed check size, not another semantic-layer press note.
