Why would it be called a "crypto" project then?
I think a perfect example is companies that have not "tokens" but have a working product. There are so many of them out there, but even then people will get interested because they think the company's stocks or shares will grow with time.
At the end of the day, people are out there to make money; a few will just do it as a hobby or something like that.
I think there are for crypto projects that have many benefits but they don't have tokens, one of them is Dexscreener is a project that I often use to find meme tokens and yes it is very useful in essence.
Others such as Base or Robinhood network so far do not have official tokens, unlike other L2s that already have their own governance tokens, Metamask also as far as I remember does not have this token wallet that is often used, or like Defilama, Electrum and others do not yet have tokens, and products from them are very often used in the crypto ecosystem to this day.
And maybe there are many more projects that are very useful in the blockchain world but they do not or do not have tokens yet.
