I have structured a few hundred rounds of financing in my career, as a founder, an owner and an advisor. There are many tools to keep from being diluted. You can establish that your stock doesnt suffer future dilution. You can sell SAFE until you get to a big Series A. You can limit the antidilution provisions that investors get. Keep in mind that the old adage that its better to have 5% of something than 80% of nothing should guide your thinking in terms of capital formation.
