Their flagship product, the Principia Analytic System (PAS), was widely adopted by banks, asset managers, insurance companies, and corporate treasuries for valuation, trading, risk management, portfolio analysis, and accounting. The company was acquired by State Street Corporation in 2000, and the Principia Analytic System was subsequently acquired by Misys (now Finastra) in 2010, where its technology continues to be part of Finastra's treasury and capital markets offerings.

Prior to its acquisitions, Principia Partners established a significant global presence, serving financial institutions across North America, Europe, and Asia. Its core product, the Principia Analytic System (PAS), was utilized by a worldwide client base for critical functions including derivatives pricing, portfolio valuation, risk management, hedge accounting, and regulatory compliance.
