About Us

Welcome to Institute Gorbach Ltd

Institute Gorbach Ltd is a specialised consulting-services provider for consumer information and consumer consulting. The company offers B2C consultancy services in the form of the "2nd opinion" model — verifying reviews and comments on goods and services offered by other companies.

Today, views, comments and positive ratings by individuals can be purchased by companies to promote their goods and services. This makes it increasingly difficult for consumers to form a fair opinion.

Our Mystery Shopping and Second-Opinion Service is an independent quality-assurance agency. We evaluate consumer goods and commercial services through undercover field operations, advanced sentiment analysis of existing customer feedback and expert comparative testing. The result: an unbiased, data-driven "second opinion" that clarifies whether specific products or services truly deliver.
