Funnel or Focus? The Builder Dilemma

Clean_Name is meant to be a free micro tool that eventually feeds users into Fileo. Right now it does one thing: rename a single PDF. No signup. Simple and useful.

My plan was to add more features: higher limits, more file types, bulk uploads. Still free, but with registration. That would turn it into a real product and give me a verified lead pool for Fileo.

But while working on this, I realized I barely touched Fileo all week. Not great.
At the same time, marketing a finished micro product is way easier than marketing an unfinished main product.

So I chose a pragmatic middle path:

I’m not building the new features yet. I'm first testing intent.
When someone clicks "Sign Up", they see a message that these features are coming soon. This tells me whether there’s actual demand before I spend days building.

First traffic. Then intent. Then features.
Until then, full focus on Fileo.

Curious how other builders handle this balance. How do you decide between pushing the main product and developing micro funnels?
