The founders who raise on the best terms are the ones who understood their numbers first.
A SAFE converts to equity at your next priced round, diluting all existing shareholders including you. The exact impact depends on the valuation cap, discount rate, and whether an option pool is created at conversion. RoundRaise models this automatically so you see the dilution before you sign.
Most UK pre-seed rounds involve 10–20% dilution. But the number that matters isn't the headline percentage — it's what your ownership looks like after option pool creation, SAFE conversion, and any pro-rata rights in subsequent rounds. RoundRaise shows you the full picture.
Yes. The decisions you make before your first round — founder splits, option pool size, instrument choice — compound across every subsequent raise. Founders who start with visibility retain significantly more control at Series A than those who don't.
