Claude: *Activates Party Mode with Paul Graham, Marc Andreessen, and Bill Gurley*
Paul Graham: "The best fundraising advice is: make something people want first.
Don't optimize for raising money. Optimize for building something users love..."
Marc Andreessen: "Software is eating the world, and VCs know it. Show us
the market size. Show us why NOW is the time..."
Bill Gurley: "Valuation is a vanity metric. What matters is finding partners
who truly understand your business..."
