Every SaaS landing page wants to signal they are a legit product. That best way to signal this is by copying other landing pages. If every landing page has a list of companies using your stuff, a chatbot, scrolling fly ins, you pretty much have to do the same thing. Whether these things are useful or not is irrelevant.
Chatbots have a real use as first level support, but it has very little use on a landing page, but that’s neither here nor there, we all simply want to fit in.
Sales is hard.
