Like the Linux command: who I am, what I do, and what I am looking for.
Who am I?
I am Viktor Winschel, an economist and systems engineer. I earned my doctorate at the University of Mannheim and have published in Econometrica and at the ACM/IEEE Symposium on Logic in Computer Science, on game theory and computation. For more than twenty-five years I have built systems that had to work in the real economy: derivative portfolios, digital twins at Volkswagen and E3DC, supply-chain finance at Traxpay, and regional platforms we co-founded — everything from ERP and logistics to the design of governance.
Together with Renée Menéndez I develop OiC.OS, an operating system for economies. It is not one more layer of integration software. It is a language in which contracts, accounts, and decisions form a single object, from a liquidity pool in a supply chain to the closing of accounts in a currency area. Questions humanity has asked for a very long time — what money is, who owes whom, how institutions compose — become practical, because you can run the answer before you sign it.
What do I do?
We build compositional finance on the OiC.OS engine. Every organisation rests on three layers: accounting that closes in real time, decisions that learn from their outcomes, and governance that prevents violations before money moves. We call this compliant by design.
The theoretical foundation is MoMaT, Monetary Macro Accounting Theory. In practice the workflow is compose, run, redesign: design an organisational form, simulate it on a digital twin, operate it live, and reshape it whenever strategy changes. Our flagship example is LiquiPool, where three firms in a supply chain share one credit facility instead of three separate ones. In the reference case this cuts liquidity costs by about thirty percent for the same capacity, because composition is not the same as addition. The same engine scales up to holdings, structured finance, payment systems, and national accounts.
We publish the research, maintain the engine, and support partners who implement their own organisational form on top of it. Further reading: Technology and Platform.
What am I looking for?
Three things, and they reinforce one another.
First, a community of people who would rather work on one engine than reinvent reconciliation every quarter: developers, treasurers, lawyers, compliance officers, and economists who care that the books actually close. Compositional finance should become the shared language of that community.
Second, projects that put the engine to work in practice: liquidity pools, treasury companies, supply-chain finance, group ERP, regional payment infrastructure. Each project is a fragment of the same operating system. We build together with teams that bring domain knowledge and market access, and we contribute the spine that keeps contract, ledger, and rules aligned.
Third, investors for this community. This is not a bet on a single product, but capital for the ecosystem: further development of the engine, onboarding of partners, reference implementations, events, and education. The aim of any investment is to grow the network of projects on OiC.OS, so that the next liquidity pool does not start from zero.
If you are building, leading a project, or investing in this direction, we should talk.
