Bootstrapping: the company is funded by revenue (and the founders' savings). You own 100% of a smaller pie. Decisions are yours alone. Growth is constrained by what cash flow can fund. End-game options: keep operating profitably, sell for cash, or take outside capital later.
Venture-backed: the company is funded by equity investors expecting outsized returns. You own a shrinking percentage of a potentially much larger pie. Decisions involve a board. Growth can be funded ahead of revenue. End-game options: become a unicorn, sell for cash, or run out of runway.
The math nobody quotes: bootstrappers who own 100% of a $5M-revenue SaaS clear roughly the same lifetime wealth as VC founders who own 12% of a $200M-revenue SaaS that exits at 5× revenue. Different paths to similar founder outcomes — for businesses that COULD have gone either way.
The path-selection question isn't "which is better" — it's "which fits the specific business I'm building."
