A dataroom software is an online repository that permits multiple parties to access and transfer files. These tools are used by lawyers, bankers as well as investors to aid in due diligence in M&A loans, loan syndications, licensing, private equity, and venture capital transactions. There are many options for datarooms. Certain are more popular than others. SmartRoom is one of them. It is primarily used by investment banks, M&A, and structured finance. It comes with upload speeds of up to 5MB per second, as well as a granular control system that includes SmartLock, redaction DocuSign integration, and dedicated project managers. It also has an 4.8-star rating on Capterra. Another alternative is the Content Snare which focuses more on information requests than managing documents.
