This is the answer

As a startup you don't have Google's money. You don't have Google's employer brand. You don't have Google's work environment.

in fact as a (hopefully) fast-growing startup the only thing you really have to offer is growth. So make it clear how you are going to help the candidate grow their career and experience faster at your startup than at the established company, and offer the best you can do on comp and work environment.

This doesn't mean fresh grads, but more like someone with a bit of experience who's ready to jump into a team lead or architectural lead role.
