As a young angel investor, my advice to entreps is something my parents ingrained in me from a young age: always have a cushion. It gives you flexibility to have a few months of expenses saved up; you can take risks and respond to surprises. Same goes for companies, especially in an environment where there's a lot more seed happening than A and B money to be had. I see way too many companies closing a smaller round and then suddenly deciding they want/need a bridge to make an extra hire, try out a new marketing strategy, etc. Just do it upfront and know you'll have the wiggle room.
