History of Deloitte

When the light bulb was yet to be invented…

Deloitte’s history dates back to the year 1849 in London. At this time Mr. William W. Deloitte invented a rigorous system to protect investors in the expanding Great Western Railway network against fraud. Such was its success that the company’s shareholders recommended the practice of external auditors be adopted into law. And so both the independent audit, and Deloitte as a firm, were born.

That innovative mind-set of William Deloitte lives on in our firm today. Integrity, brining outstanding value to clients, commitment to each other and cultural diversity are the foundation of our work. We seek to drive higher standards of governance and transparency through our audit and tax practices, bringing confidence to the key decisions of business and government alike. Our people are responding to the ever evolving needs and challenges of clients and society by pushing the boundaries of our work in consulting and corporate finance advisory. 

How Deloitte Finland was born

Deloitte & Touche Oy was born in the beginning of 1995, when Tilintarkastus Oy Hietala, Paul & Tuominen (founded in 1993) and Tilintarkastustoimisto Yrjö Tuokko Oy (founded in 1971) joined forces and set up an office together. Deloitte Consulting, providing management consultant services, set up shop in Finland in 1998. Deloitte Consulting was integrated with Deloitte & Touche in 2003 and so one united Deloitte was born.

Today we are a part of Deloitte Touche Tohmatsu Limited (DTTL), which consists of legally separate and independent member firms in over 150 countries providing audit, consulting, financial advisory, risk management, tax and related services. We have more than 210,000 professionals globally and are one of the world’s largest private audit and consultancy firm.
