Research and infrastructure for complex financial problems
Herfel og Rangen develops independent financial research and analytical infrastructure for markets where conventional approaches to valuation, liquidity and uncertainty become insufficient.

Herfel og Rangen is an independent financial research and analytics firm founded by Julius Herfel.
Its work sits at the intersection of financial markets, quantitative modelling, liquidity and institutional risk - particularly where limited data, imperfect transferability or model uncertainty make standard approaches inadequate.
The firm currently develops its work through Herfel og Rangen Research and PHYTIA, with HEIDRUN in pre-development.
