If you dual-license your software in such a way that it requires a paid license for commercial use, here are two code blobs for you.

macOS⌗ 

pub fn mdm_enrollment() -> eyre::Result<(bool, Option<String>)> {
    let mut command = Command::new("/usr/bin/profiles");
    command.args(["status", "-type", "enrollment"]);
    let stdout = command.output()?.stdout;
    let output = std::str::from_utf8(&stdout)?;
    if output.contains("MDM enrollment: No") {
        return Ok((false, None));
    }

    let mut server = None;

    for line in output.lines() {
        if line.starts_with("MDM server") {
            server = Some(line.trim_start_matches("MDM server: ").to_string())
        }
    }

    Ok((true, server))
}

Windows⌗ 

pub fn mdm_enrollment() -> eyre::Result<(bool, Option<String>)> {
    let mut command = Command::new("dsregcmd");
    command.args(["/status"]);
    let stdout = command.output()?.stdout;
    let output = std::str::from_utf8(&stdout)?;
    if !output.contains("MdmUrl") {
        return Ok((false, None));
    }

    let mut server = None;

    for line in output.lines() {
        if line.contains("MdmUrl") {
            let line = line.trim().to_string();
            server = Some(line.trim_start_matches("MdmUrl : ").to_string())
        }
    }

    Ok((true, server))
}

Looking at mobile device management (MDM) enrollment is not a silver bullet for identifying corporate devices running your software, but it is a good start.

A productive next step would be to put together a list of known corporate MDM server URLs in a public repository to allow for more granular identification.

This is something anyone with a corporate device enrolled in MDM can contribute to by running profiles status -type enrollment on macOS or dsregcmd /status on Windows.
