I don't think just distributing it for free will net you revenue. Usually people need a reason to pay. I personally will pay for something if really want it, and I'm incredibly annoyed by the free alternative. Likewise, someone in a small team in a big company will use your software for free, but until they get annoyed enough by it, they won't convince their boss to pay for it to avoid the annoyance (or gain the premium feature, etc). In this sense, the value driving the purchase is the pain factor, not how useful the software is by itself.

You should also tailor your business model to the product's market. If you have a broad market - home users, small business, large businesses, etc - some can use it for free, but some will still pay. If it's a smaller market - only small businesses - maybe only a few will pay if it's available for free.

You can also change the business model to be free software that drives paying for something else - like a cool cli tool, but a much more useful premium GUI. Or a free tool that's easier to set up and use as a SaaS.
