Need composite charts of business partners

I have been doing composite charts for decades for romantic relationships, and I have found them to be very accurate and use them in my practice. It is relatively easy to find charts for long standing, successful romantic or marriage partners. But it is much harder to find data for bsiness relationships especially the ones that failed. There are some famous big successes like Ben and Jerry's or Rodgers and Hammerstein,(whose charts I have done) etc. I want to collect data for research but it is almost impossible to find data on failed business partnerships. I have done hundreds of composites for romantic partners but less than a dozen for business partners.

So if you might have had an unsuccessful partnership and can offer me the birth data for both parties, I would greatly appreciate it. No names need to be given, but it would be helpful to know the nature of the business and a little bit about why it failed.
Thanks!!!
