Calculate raise amount, dilution impact, and runway extension.
Aim for 18-24 months of runway. Typical seed dilution: 15-25%. Series A: 20-30%.
Fundraising is one of the most consequential decisions a founder makes. The amount you raise, the valuation you accept, and the resulting dilution will shape your ownership and control for years to come.
A common rule of thumb is to raise enough capital for 18-24 months of runway. This gives you sufficient time to hit meaningful milestones that justify a higher valuation at the next round.
Typical dilution ranges: pre-seed (5-15%), seed (15-25%), Series A (20-30%), Series B (15-25%). Dilution is not inherently bad if the capital enables disproportionate value creation.
