Modern thinking applied to financial software.


Re-Engineering the Financial Markets

TXIO was founded in 2007 in Toronto, Canada. Our founders understood that success in the financial markets increasingly depends on technology, and set about creating a new generation of financial software driven by research, innovation and outstanding design. The result is our core product, The MarketDepth System — a software toolkit for finance.

TXIO licenses The MarketDepth System to banks, financial brokers, wealth managers and investment professionals world-wide. See our Products page for more information, or contact us at
