Feeling Stuck at an Early Startup

I have been working at an early staged startup since an year almost, the product has grown well and seems to be on course towards a great trajectory. The only problem I have is I feel I’m not compensated enough for the amount of responsibility and work I do. It’s a super challenging environment and the founders have delayed the hike cycle to a funding round since the product has almost matured and they might raise soon. I feel if I ride the emotional wave of trusting the product, I might be left with a lesser than average hike instead I should start looking out because some folks in the company have also been made false promises in the past about hikes and raises. Should I wait it out since I’ve spent a lot of hardwork on the product and see if the same happens to me. What would you guys do? My focus is earning more and I’m highly driven towards improving myself. I hoped if I work well for the product, rest of the thing will take care themselves and I’ll also be offered a chance to be rich but it seems not like that at the moment.
