Repeat after me:
1 ICP. 1 UVP. 1 core problem. 1 flow. 1 acquisition channel.
Founders love optionality. They target two segments. They test three channels. They build two features "just in case."
That's pure insecurity.
Change two variables at once, and you learn nothing. Did the offer fail? Or the audience?
Pre-PMF, the "power of one" is absolute. If you can't make it work with one, you won't make it work with two.
Prove one. Then add.
