I would not recommend just putting it on the company's website or emailing it to anyone - if you sent it for publication, you would get:

- peer review and feedback of your algorithms, assumptions and conclusions.

- potentially, validation for your application of the underlying rigorous mathematics.

Unless this is proprietary information, I would suggest that if you have had the work verified internally, perhaps ask them to be a co-author.

Being published would bring it to the attention of those in the same field, potentially allowing more valuable feedback and allowing further development and research to be performed on the work you have completed.

Finally, why not get published recognition for your work.
