What is another word for on the back of?
Pronunciation: [ɒnðə bˈak ɒv] (IPA) 
When expressing a sense of associative or reliant relation between two items or subjects, "on the back of" can be substituted in many ways. "Based on" can be a good option to mean that an idea is grounded in another one. "Influenced by" would replace the sentence if a person was mentored or inspired by someone else. "Supported by" would convey the idea of aid or funding, or alternatively, if a viewpoint was grounded in research. The phrase "built upon" would aptly describe theories or practices that derive from other ideas. Similarly, "revolving around" would be relevant in a discourse and means that a subject is the core of it. Finally, "following" would suffice as an alternative when one idea leads to another.
