 Now let's talk about the top three differences between B2B and B2C product. Number one, customer discovery phase. For B2C product, you will still do a lot of customer interviews, maybe 10, 20, 50 customer interviews. But given a large amount of B2C customers, they frequently introduce a large amount of survey so they can hit thousands of people's response and see a trend. And whatever trend they receive, they are going to build new features to test out in those B2C apps, such as TikTok and Instagram. And then they're going to run AV testing to understand what kind of part of features is actually working and improve the bottom line of the product and hit their North Star metric.
