Hi! I'm actually currently working with a startup out of the Harvard i-Lab who is also going through the same process (except they are on their seed round). Are you looking for a responsive cap table design? If you give me some more information on the kind of investments you've received, I should be able to make a round-by-round responsive spreadsheet.
As a fellow start-up guy, if you're still working on committing the round, make sure to try angelist after you hit 60%!! Good luck to you.
