Hazeltree, a treasury and liquidity management platform serving the alternative investment industry, has acquired Siman Systems, a specialist in margin replication and financing analytics, in a move set to deepen its offering for hedge funds and asset managers.

Announced this week, the deal strengthens Hazeltree’s position as a comprehensive treasury management solution, particularly for multi-prime, multi-asset managers seeking greater precision in margin optimisation and cost efficiency.

Siman’s technology – already adopted by several leading hedge funds – offers real-time margin replication, collateral optimisation, and detailed pre/post-trade analytics across multiple counterparties. These capabilities will now be fully integrated into Hazeltree’s treasury management platform, providing clients with a unified view of liquidity, cash, margin, and financing exposure across portfolios.

As part of the deal, Siman Systems founder David Simpson has joined Hazeltree as Managing Director of Hedge Funds, alongside Ray McGrath, who becomes Director of Platform and Engineering. The broader Siman team, including treasury and margin specialists, will also join Hazeltree.
