My company filed for an IPO and the lockup ends in six months. My vested shares are worth more than I'll earn in the next five years. How much do I sell on day one?

I'm 34, make $68,000, and just started putting money away for the first time. My company matches 4% on my 401k but I also want to save for a house in three years. I don't know how to split what's left between the two

There are three of us starting this company: two of us quit our jobs to work on it full-time, one is staying at his job and advising on weekends. We're trying to decide if he still deserves an equal third of the equity. Whatever we agree on now, we'll be stuck with for years

I've had the same job, same apartment, same weekend routine for four years. Nothing's wrong exactly, but I realized last week I couldn't remember the last time I tried something new. Is this what being stuck feels like?

The honest answer: if you're not sure, you probably don't have it yet. When you truly have product-market fit, people are fighting to get in. You're not questioning it.

The clearest signal is retention: are the people who try your product coming back without you having to push them? If they are, you likely have product-market fit for a segment. If they aren't, the rest is noise.

Make it a conversation

You can ask
“What about me?”

Go beyond reading or watching. Ask their Delphi a question, bring your own context, and follow the ideas that matter to you.

Explore a different angle, ask why, or dig into how something applies to your situation.

If you're not sure, you probably don't have it yet. When you do, people are fighting to get in. Start with the Sean Ellis “very disappointed” survey and look hard at retention. Those two give you the clearest read.
