One need to experiment different sources based on the engagement they have seen in different social media platforms. Calculate CPA and CAC depending upon your product is free or priced. and then take decision based on that. It's too early to say what would work best. I am still learning on this topic! Best of luck 🫡
You can test markets very quickly and for a precise budget. That's very high-value since the market in some ways trumps team/product. I've heard lots of people talk about testing markets early on rather than features!
This is a great question to ask! In my opinion, if you "Start with why", you'd want to connect with people who believe in your why's. Which is exactly what all they are to believe in their why's. So, your goal then becomes to find people who believe in what you believe and the product is something which both your users and you'd be believing in as a stakeholder.
@rupal_saini well you could also materialize a brand's values and find people aligned with those values! Apple is a great example when they stand for "differences".
