Of course it’s not necessary. Did you/advisor read the SAFE? Now it’s time to decide if your “advisor” (investor?) is bringing enough to the table to comply with his amateurish requests and handholding.
He is very senior and not amateurish, I think the issue is he does not like SAFEs (says they are not SEC-tested) and thus I think won't read them, and thinks any deal of any sort without a summary term sheet is not 'serious'.
Thanks.
