In 1988 he acquired control of a publicly traded company named "Eichut Computers", which he turned into the communications arm of the developing Formula Group.

He founded Foraz, the first Israeli Venture Capital Fund, together with Liraz, a publicly traded company headed by Arik Kilman.

He also acquired Nikuv Computers, one of the first publicly traded software services companies in Israel specializing in Salary calculation, which owned a prevalent ERP system for small and medium clients.

Throughout this decade, some of Goldstein's earlier investments have reached a size which justified public offerings, and raised funds on The Tel Aviv Stock Exchange, the AIM market in London, and on Nasdaq: Crystal Software Solutions and Wiztech (later wholly acquired by Convergys) were the first two greatly successful offerings, followed by ForSoft, the traditional Software Services arm of the group throughout the 90s.

This publicly traded group of technology companies headed by Yaki Dunietz and David Assia, consisted of established businesses such as Magic Software Enterprises, Babylon, Paradigm Geophysical and Walla!

[3] In March 2000, one month after Magic Software's successful secondary offering for a record evaluation, the technology bubble started to burst.

He consolidated and simplified the complicated multi-level corporate structure, which was a half arbitrary result of many historical and fiscal reasons.

Control of the Formula Group was transferred to Fimgold, a partnership between Goldstein and the FIMI opportunity fund, headed by Ishay Davidi.

[8][9] In the years that followed, Goldstein found himself leading a publicly traded corporate pyramid as well as group of young, promising yet struggling companies in the portfolio of Formula Vision.

As such, he was very involved in legislation and public debate over issues pertaining to subjects such as corporate governance, financial regulation, reporting and accounting standards.
