It's crucial for founders to understand their dilution when raising money through SAFEs or convertible notes, as they may end up owning significantly less of the company than expected after a priced round.

The introduction of post-money SAFEs simplifies understanding dilution by clarifying how much of the company founders have sold to investors after all SAFEs have converted.

Founders need to be aware that their ownership percentage can decrease significantly due to dilution from SAFEs and new equity rounds, so they should plan accordingly for future fundraising. The percentage of ownership for SAFE investors is based on the valuation cap in the SAFE, and if the priced round valuation is higher than the cap, they convert at the cap, receiving more shares for the same investment than Series A investors.

When raising funds, it's advisable to use post-money SAFEs to simplify calculations and better track future dilution, even if pre-money SAFEs have been used in the past.

Founders often lack understanding of the complexities of SAFE conversions and dilution, which can lead to confusion during fundraising.

Founders should be cautious about how much they raise on SAFEs, as it dilutes their ownership in the company.

Don't over-optimize for valuation caps when raising money on SAFEs, as the difference in ownership percentages may not be significant, and the focus should be on making the company successful instead.

Valuation, which is the value of your enterprise, and dilution, which refers to how much of your company you have sold, are critical concepts in fundraising.

It's crucial for founders to keep track of how much equity they've sold through SAFEs, as this affects their ownership percentage and future fundraising.
