Faraday cage for the win. My printer stays offline - period. If something needs printing, I have to sneakerware it. If I'm unable to do that, I rethink whether it really needs printing in the first place :D
The thing I find interesting is that doing the research gives me a new perspective on whether or not I really want to go after that business/model. The SEO search turns up potential competitors, domain squatters, etc. While thinking about different names to lookup and key words to search for, my context changes to a potential customer...
A lot of times it reminds me ("oh yeah... did I talk to real potential customers yet?") and if I didn't, I'm in real trouble of building another tool that no one wants :(
It's on the top 10 list of things to consider - along with finding real customers. How high is debatable. If your product/service resonates with customers, you could change the name to something more appropriate later. It might be expensive to buy the right domain, but if you've got $ or stock that's worth something, it's totally doable.
Consider the fact that a brand and the company name are two separate things. Think Uber Cab (Uber), Google (Alphabet), Tide (P & G). The domain name can/should be tied to the product - and the brand. The company name itself can be anything really. As a first step to a rename if you really really want to do it, you could file an incorporation document amendment that says "Company AD15asd Corp, d.b.a. NiceBrand"
