The firm expanded internationally in 1890 by opening an office on Wall Street in New York. Over the years, Deloitte has grown through both organic growth and strategic mergers. Key milestones include its merger with Haskins & Sells in 1972 and with Touche Ross to form Deloitte & Touche in 1989. The firm has continued to expand globally and has diversified its service offerings beyond auditing to include consulting and advisory services.
As a privately held partnership, Deloitte does not rely on external funding like venture capital or public markets. Its growth has been financed internally through its partners.
