It’s Official: Kapco Global is Now Proponent

We Are Proponent

On February 19, 2018, we announced that Proponent would be the new trade name for Kirkhill Aircraft Parts Co., replacing the Kapco Global moniker. This is an incredibly exciting time for Proponent, capping off nearly a year of feverish work.

For those of us who have been working behind the scenes to bring the Proponent identity to life – determining the name, choosing the logo, developing the brand voice and look, not to mention ensuring a seamless transition for all of our customers and supplier partners – it feels like this announcement has been a long time coming. However, we can understand how it might seem sudden and confusing to some, after decades of doing business with Kapco. In this post, we discuss why we made the change and what definitely won’t change.


Our New Name

The Proponent name was chosen to emphasize our deepened focus on customer and supplier relationships. These relationships have always been important to us, but our partnership with Avio-Diepen helped us to increase our supply chain offerings and to greatly expand our portfolio of aircraft parts – all in service to our customers and suppliers.

Our President and CEO put it best: “The name ‘Proponent’ is a one-word mission statement. It means ‘advocate, champion, supporter.’ We have always placed a high priority on our relationships, but this name change is a recommitment to doing whatever we can to be a champion for our suppliers and customers.”

The Proponent identity launched in October 2017 as the parent company of Kapco Global and Avio-Diepen. With our focus shifting more and more toward being a “champion” for our clients, it only made sense to change our name completely. As Proponent and Avio-Diepen continue on the path toward full integration, Avio-Diepen is expected to complete its integration into the Proponent name by early 2019. Together, we are the world’s largest independent aerospace distributor, but our focus remains on individual relationships and doing everything in our power to provide customized solutions that address our customers’ objectives and maximize their opportunities.
