I'm not an authority on this, just someone building without a round who thinks more founders should weigh it.
I'm not an expert on this, I've just been building without a round and I keep thinking more people should at least consider it before defaulting to raising.
Here's my actual bias, up front: I don't love taking money from people. The second someone hands you money, they get a say in what you do with it. I'd rather move slower and keep the thing mine. That's personal, not a strategy.
But there's a less personal reason too, and it's the one I'd actually make to someone else. A few years ago, bootstrapping meant giving something up, speed, polish, how much you could get done alone. That gap's a lot smaller now. AI is doing a chunk of what used to need a small funded team, so one person can get further than they used to be able to by themselves. If you're building something where the AI-assisted version of you can do 70% of what a five-person team could've done in 2019, that changes the math on whether you need the round at all.
I looked for a real number to back this up before writing it, something like "X% of founders are going solo now." What I found instead was a pile of thin content-farm posts with no actual source behind the number. So I'm not going to hand you a stat I don't trust just to sound more convincing. What I do believe, from paying attention rather than from a citation: valuations aren't where they were in 2021, and it costs a lot less to build something real than it did a few years back. Building's gotten cheaper. Raising money you don't strictly need has gotten harder to justify.
So before you take a round, it's worth actually asking what it buys you beyond the money, because for a lot of founders right now, the honest answer might be less than it used to be.
