Abelium R&D
Ljubljana, Slovenia
About
Abelium R&D is a Ljubljana research and development company founded in 2009, working in mathematical optimization, operations research and tailored algorithms, with forecasting and hybrid-intelligence platforms among its published research projects.
Our Take
Abelium is a research house first: founded 2009 in mathematical optimization and operations research, with EU-funded projects—satellite-based photovoltaic forecasting for grid stability, digital tooling for cattle farming—sitting alongside the client work.
The AI-era evidence is its own product rather than a client deployment. so-yesterday.ai is live, and its architecture is described in detail: three information layers, on-premise open-weight models for chat and embeddings with frontier APIs only where they help, and a cryptographically verifiable audit trail on every synthesized claim, built explicitly as a proving ground for regulated environments.
The named client work is older and not AI—the GoOpti transport marketplace ran 2014 to 2018 on optimization algorithms, reporting more than 32,000 passengers a month and a 93% satisfaction rate.
Best for buyers with a genuine optimization or research problem—forecasting, scheduling, algorithmic matching—rather than a language-model deployment, and worth asking what that architecture would cost applied to your own documents.
Key strengths
- Optimization and operations research as the core discipline, with published EU-funded research projects behind it rather than a services page
- The architecture of their own platform names the hard parts: on-premise models for confidential data, frontier APIs only where they earn their place, and an audit trail tying every claim to a source
- The GoOpti engagement ran four years and is backed by a client review on a third-party directory
Good to know
- The AI-era system is their own product, not a client deployment—ask for an engagement where they built this architecture for someone else
- The named client work predates the language-model era—ask what has been delivered since 2023 and for whom
- At €85–130/h this is the highest published rate in Ljubljana—confirm what research-grade work costs against a scoped delivery
