Building a new world of finance.

We bring new ideas

We develop new ideas and concepts for a new financial world.

We believe that technical infrastructure has become a high entry barrier on financial markets. Due to high costs and increasing regulation fintech markets become increasingly closed. Big players which can pay for the infrastructure dominate. Smaller players are forced into speculative strategies to survive. In total we are seeing higher speed, bigger failures and more risky strategies.

We believe that future financial markets can be open for everyone with a good idea. Instead of only buying low and selling high, the focus of finance can be shifted to participation and collaboration. Such new contracts can lead to a longterm creation of wealth, and build-up of equity for entrepreneurs which improves lifes, leads to prosperity of companies.

We confront classical banking with vision, fresh new ideas, and concepts using blockchain, open ledger or algo technology. We see ourselves as an idea-generator and thinktank, delivering concepts, expertise and software code. We are supporting startups which disrupt and re-invent the world of classical finance in our mission. Our toolbox is a quantitative skillset with experience in financial technologies: i.e. realtime analysis of mass data, hft algos, co-location and blockchain.
