Case Study: Double River reduces simulation time from days to hours with Coiled

How Double River reduced simulation time from days to hours for faster trading decisions

Double River Investments, a quantitative hedge fund, faced significant computational challenges. Their previous stack using Pandas and Google Cloud Run was limited by memory constraints and slow processors, causing complex trading simulations to take days. This bottleneck forced them to make difficult trade-offs between the scope of their analysis and timely decision-making. They turned to Coiled for a solution to these infrastructure and performance limitations.

By implementing Coiled's on-demand cloud computing platform, Double River gained access to flexible, high-performance hardware with minimal code changes. This new capability, integrated with their Polars and Prefect stack, allowed them to run simulations in parallel. The result was transformative: simulation times were reduced from days to just hours. This acceleration enabled faster trading decisions, more robust strategy testing, and freed their engineering team from infrastructure management, providing a key competitive advantage.
