I have limited experience compared to many people on here, but 30% for a seed round seems higher than average. It might make more sense to go straight to a series A where you will likely get more money than a seed round (expanding abroad is always more expensive than you think). I don't know which county you're in, but many (if not most) U.S. investors will be wary of investing in a company where 50% has already been given away, making it difficult to raise more money later. Exceptions are made if you're doing incredibly well and they're guaranteed to make money, but on average it's not something they like.
