Company and investor counsel
Data rooms for law firms on investment deals
Counsel on both sides of a financing live in the data room: requests, review, disclosure schedules and finally the closing set.
Investor counsel send a request list, review the room and raise issues; company counsel fill gaps and draft disclosure schedules. At closing, signed documents go into a closing set that both sides keep.
Law firms care about confidentiality, privilege, audit trail and clean exports for the closing binder.
What matters most: A defensible record and clean exports matter as much as the review itself.
