The reply comes by email: an indicative structure and the conditions attached to it, or a straight answer that this is not something we fund. A two-line note saying what you are listed on and what you need is enough to start. Structure of interest is optional — see the instruments if you want a view first.
Do not send anything you are not free to send. An unannounced raise is normally inside information. Venue, size, purpose and timing are enough to structure an answer; draft documents and anything under a confidentiality obligation should wait until a non-disclosure agreement is in place. Sending an enquiry does not put us under a confidentiality obligation unless one is separately agreed in writing, and it creates no client, advisory or fiduciary relationship.
