the language from the DD prep module might be good here:
Thank you for your interest in meeting.
Right now, we are heads down on customers and product. We are happy to invite you to our Demo Day when we will kick off our institutional raise. If that's of interest, please fill out this form: https://influencerseries.wufoo.com/forms/alchemist-accelerator-request-investor-invite/, and we will extend you an invite. We can also set up a meeting with you immediately after our Demo Day if you like.
We are taking a limited amount of capital in now in advance of our Demo Day. However, we will not be able to meet given time constraints. If you would like to invest without having a meeting, we can send you the Alchemist SAFE that we are taking a limited amount of capital on now if you are able to make a quick investment decision with no meeting / limited information.
My best,
[Your Name]
