[4] Wilshire was founded in 1972 by Dennis Tito, who was an early pioneer of applying computer-based technologies to investment applications.

Wilshire established an early reputation[citation needed] by creating the first asset/liability model for pension funds in the 1970s, ten years before actuarial and accounting firms began to adopt this technology.

In 2003, Wilshire was targeted by New York State Attorney General Eliot Spitzer in connection to its trading practices as part of a wide ranging 2003 investigation of mutual funds.

The Wilshire Quantum Series is Wilshire Analytics' family of software for investment accounting, performance measurement, performance attribution, risk management, portfolio optimization, trade order management, and other marketing and client servicing support for multi-currency portfolios.

Wilshire's Consulting division provides investment consulting services including asset allocation, investment structure, manager search and performance measurement to public and corporate pension funds, endowments, foundations, and insurance companies.
