If so, I'm still unclear as to why banks would be okay with institutionalizing what seems like a pretty sketchy process. As a junior analyst, sending internal spreadsheets to your friends at other firms, just so you can save time, does not seem like the most policy-compliant approach to reducing your workload. I fail to see why banks would be okay with their junior analysts sharing spreadsheets with their counterparts at competing banks, especially when sent through a third party.
Obviously you know more about this than me, so hopefully you can clarify.
EDIT: after checking out your site instead of just the (poorly explained) article, your business makes far more sense. However my question still stands in regards to collaboration. Won't companies want to protect internal modeling strategies?
