Delphi is a powerful tool in the right hands. If you no longer have the staff to maintain your critical application, we can help!


Staying as close to the leading edge as possible, we keep an active subscription to Delphi Enterprise and start all new projects here.

We have several projects written in Delphi 10.4, a very solid, cross-platform development tool. In fact, we used this version of Delphi to write a book about taking Windows-only skills and expanding them to embrace the Mac, iOS, Android, and Linux platforms.

Released in 2010, Delphi XE was the last version of Delphi that targeted only the Windows platform. We support two major projects that are in maintenance mode using this robust development platform that still works great on today's Windows 11 computers.

Delphi 7 is 20 years old but believe it not, it still works (although we miss features in newer versions)! It is used to support legacy applications that either cannot or have not yet been upgraded.
We have a few other versions of Delphi installed for specific clients, some of them on dedicated virtual machines:
- Delphi 10.1 Berlin
- Delphi XE4
- Delphi XE2
- Delphi 5 (for writing BPL plugins for Retail Pro 8)
The team at Cornelius Concepts collectively has over 50 years of experience working with all versions of Delphi in a wide variety of environments and supporting a plethora of third-party components, libraries, databases, and file formats. If you are wondering where to turn for continued support of your legacy application, or if you need help getting your new cross-platform application off the ground, look no more, we've got you covered!
