What Do You Do?

Y Combinator spends a wild amount of time on one thing. It's not metrics. Not code reviews. Not bro-ing down with VCs.

It's rehearsing the two-sentence explanation of what you're doing.

Two sentences. Sounds easy. It's really not.

You're trying to make someone imagine something - without knowing what they'll imagine.
You're taking on feedback constantly, so it shifts.
The person you're talking to shifts.
And it has to sound like you, not like a deck. And not like an AI.

This isn't a positioning statement (sorry, brand strategy friends).
Those are internal documents - you don't say them to people.
Coca-Cola doesn't walk around saying "we refresh the world and inspire moments of optimism." (At least I hope they dont)

Your two sentences have to feel casual enough to say at a barbecue.

The thing is, this applies to everyone. Not just founders of bazillion dollar world-ending companies.

How do you explain what you do - in two sentences - in a way that lands differently depending on who's asking?

Your career. Your side project. Your freelance thing.
The company you've been at for twelve years but still can't quite describe to your parents.

I don't have a tidy framework.

But I suspect this skill matters more than most - and almost nobody practices it.
