Provided I raise a first investment from angel on X valuation, then raise another one from same angel on X+Y valuation, what would be the total amount of percentage the angel will have of the company?
I mean, it's clear his/her first investment percentage will become lower, but how these two percentage are summed?
I guess it's pretty trivial to calculate, but for some I reason I have a mind block at this time of the night.
Thanks!
