Perhaps less relevant as the fundraising proceeds and the valuation approaches the targeted IPO price. But early on, the valuation will probably change drastically from Seed to C and securing an appropriate % is a good strategy. Many people don't know what that is -- for instance I accepted my first seed stage equity offer of 0.5% (negotiated up from 0.25%) but I now know that I was slightly lowballed. But you still make a good point. 1% from two 23yo first-time foundres with little experience, vs 0.5% from established founders with prior exits, solid networks, and reputable VC's presumably greatly increases your odds of a high valuation exit, so perhaps even seed / A stage its worth weighing that more than the percent.
