Given that rank 4, 6, and 8 give more members, the maximum rank is 15, assuming rank 10, 12, and 14 give +2 each that would be 30 members. Since if you have more than 30 members you could have the SR goddess drop before everyone unlocks her (assuming a perfect donation alliance), 30 seems like a decent educated guess.
