How to get the first 100 users for a free tool nobody has heard of
Get the first 100 users for a free tool by launching it three times in three different places rather than once everywhere: post it where the problem is complained about, submit it to the two or three directories your audience actually reads, and message twenty people individually who have publicly described the problem. Free removes the price objection but not the attention problem — a tool with no distribution gets no users regardless of quality, and the day the hundred arrive is when the real work starts.
The workflow
No signup, no email, no configuration before the tool does something useful. Every field between arrival and value costs you a large share of first-time users, and a free tool has no leverage to demand anything. Ask for identity only after the person has already got something out of it — that ordering typically doubles the number who ever reach the value.
Not "a utility for optimising X" but the sentence they would type into a search box. You will use this sentence in every launch surface, so it is worth twenty minutes. Take it from a real complaint you found rather than composing it — the phrasing people already use is the phrasing that gets clicked.
A single launch post is one roll of the dice. Post in the community where the problem is discussed, submit to two directories your audience actually reads, and put it in front of one relevant newsletter. Three surfaces over two weeks reliably outperforms one big launch, because each teaches you which audience responds and none of them are repeatable if you burn them all on the same day.
Search for the complaint, find people who wrote it in the last few months, and send them the tool with one line: you mentioned this, I made this, it is free. This is slow and it converts better than any launch post, because it arrives with proof you read what they wrote. Twenty messages is an afternoon and typically produces more engaged users than a hundred anonymous clicks.
- Input
- Free tool page: subject-line grader for newsletter writers, no signup
- What comes back
- The tool is below the fold behind an explainer — move the input box to the top; for a free tool the page is the tool. Also missing the one line free tools need most: what happens to the data you paste. Add "runs in your browser, nothing is stored" beside the button.
Run it yourself — free, no signup:
How many people reached the value, and how many came back within a week. Everything else is decoration at this stage. If most visitors never reach the value, the problem is the first screen; if they reach it and never return, the tool solved a one-time problem, which changes what business could sit behind it.
The people who came back twice are your only real research population. Ask them what they were doing before, and what they still do by hand. The paid product almost always lives in that answer rather than in an upgraded version of the free tool — and a hundred users, ten of whom return, is enough to find it.
- Input
- Free subject-line grader. 340 visitors in 2 weeks, 190 reached a result, 24 returned in week two, 3 asked for bulk upload.
- What comes back
- CONTINUE, and the paid product is not the grader. 13% week-two return on a free utility is healthy, and the three bulk-upload requests point at agencies rather than individual writers. Talk to those three before building any premium tier.
Run it yourself — free, no signup:
Who it's for, what it does, what they pay. The more specific the sentence, the sharper the read.
Questions founders ask about this
- Why is nobody using my free tool?
- Almost always distribution rather than quality. Free removes the price objection but not the attention problem — a tool launched once, in one place, to an audience that was not looking for it will get no users no matter how good it is.
- Should a free tool require an email to use?
- Not on first use. Every field before the value costs a large share of first-time users, and a tool nobody knows has no leverage to demand identity. Ask after the person has already got something out of it.
- Where should I launch a free tool?
- Three places rather than one: the community where the problem is complained about, two directories your audience genuinely reads, and one relevant newsletter. Spreading launches over two weeks also tells you which audience actually responds.
- How many free users do I need before charging?
- The count matters less than the return rate. Ten users who come back weekly are a better basis for a paid product than a thousand who used it once, because repeat use is what indicates an ongoing problem worth paying to solve.
- How do I turn free users into paying customers?
- Ask the returning ones what they still do by hand. The paid product usually lives in the adjacent manual work rather than in a premium version of the free tool itself.
