A $1M seed round should be more than enough to get a SaaS business cash flow positive or get a consumer product to a meaningful user base. If you have failed to get there on a seed round, the answer isn't "give me more money", it's "the market is telling you to try something else".
$1M can be 2 years of runway. That's a long time to figure out what you need to do to get to product-market fit.
Most successful businesses don't have anywhere near that level of funding and are still able to make money on more constrained resources.
