Yes, it is generally important to communicate the final closing date of your fundraise to your limited partners (LPs) and other stakeholders. This helps manage expectations and ensures transparency in the fundraising process. However, the specific timing and manner of communication may vary depending on your fund's circumstances and agreements with LPs.
You should avoid communicating a final closing date until you have enough signed LOIs from LPs to proceed, or your fundraising period is expiring as per the terms of your LPA.
