This is going to be a bit ranty, but hopefully it will also be useful to some people!
Hands down, one of my most hated questions is "How did you get your first 25 customers?". I get asked it a lot in my twitter DMs, so much that I actually wrote a whole post about it. I try to answer these inquiries where possible, but I can't help but think that the right questions aren't being asked.
I see this question getting asked over and over again directed at founders on twitter, and on Indiehackers - in the recent AMA by AJ of Carrd he gets asked this several times over in different permutations.
I feel that a lot of new entrepreneurs simply think that success is down to having a product and throwing it at a magic distribution channel. I'm sorry to have to tell you, but it's much harder than that.
The question is not specific enough to gain learnings from. It's too wide open - successful founders will have probably tried a list of 100 things to get their first X customers. They aren't going to tell you all 100, just the ones they remember, and there's no guarantee those will be relevant to you.
The question makes the indirect assumption that both Product A and Product B are equal, and therefore by knowing how A got customers, one can apply the same methods to B and enjoy the same success.
Here's the reality check: Your product is different. It has a different market, different use case, different value proposition, and different relevant distribution channels.
When you ask this question and the founder replies something like "oh I sent it to my newsletter list of 10,000 people" or "oh I'm huge on LinkedIn" what are you going to do with that information? You don't have either of those things. So it's redundant information. You've wasted the chance to learn something useful.
Focus on the things that your product and their product actually have in common. And try to learn what they did in those specific areas.
You both (probably) have:
From that, you can draw up things you might want to learn about these parts of the customer journey, e.g.
This is a rant, yes, but I assure you my heart is in the right place. I want many other indiehackers to be successful and a big part of that is asking the right questions when there's an opportunity to do so :)
