The consultancies and vendors that actually do Delphi / Object Pascal modernization work, and what each one specializes in. This is a general market overview, not a paid placement or an endorsement.
Delphi's current owner
Idera owns Embarcadero, which develops Delphi (RAD Studio) itself, including migration tooling for older Delphi codebases onto current compiler versions.
Best for: Delphi shops staying on the platform and modernizing the codebase within it.
Automated code and database conversion across many legacy languages
A longstanding conversion-tooling vendor covering a wide range of source languages, including Delphi versions from 5 through the current release, converting to Java, C#, Python, or VB.NET, alongside separate database migration tooling.
Best for: Teams that want an automated first-pass conversion across a specific version range, then a human review pass.
