People respond to leadership, in business as in any other field.
Even small organisations can be thought leaders, if they introduce new concepts and services.
Is there a need in your field for better collation and access to information? For quick reference information, safety, first aid, emergency response, practical advice, instructions?
You can position as a leader, by introducing an app that meets the need.
It's the kind of credibility you can only get by doing. Your big competitors can advertise forever saying they are leaders, but you can move in front of them, in the eyes of customers, by doing it.
