Building a brand that people trust is important when developing an AI product. While AI capabilities may be impressive, they only make up a small portion of the puzzle. Startups need to consider whether existing products and technologies are still relevant in the future. If they are not, they would need to build everything from scratch, including features like login systems. However, if a competitor like MailChimp already offers essential features, it would be challenging to catch up even with the help of AI. MailChimp has a well-established brand and features like high deliverability rate and email analytics, which would take months or even years to replicate.
