How to Get Your First 100 Users for an AI Tool

The first 100 users are the hardest. You don't have reviews, a brand or a marketing budget — just a product that you believe solves a problem. The good news: you don't need scale yet. You need the right 100 people, and you can find them by hand.

Here are ten approaches that work for AI tools on a small budget, roughly in the order we'd try them.

First, define a "real" user#

Before chasing numbers, write down the moment someone gets value from your product. Not "signed up" — something like:

• "Generated their first set of product photos"
• "Got a meeting summary emailed to the team"
• "Ran a query against their own database"

That's your activation event. A hundred activated users will teach you more than a thousand sign-ups who never came back.

1. Start with people you can name#

Write a list of 30 people who have the problem you solve: former colleagues, people in your network, people who've complained about the problem online. Message them one by one. Not a pitch — a request:

"I built a small tool that [does job] because I kept [pain]. Would you try it for 10 minutes and tell me what's confusing? Happy to set it up with you."

This feels slow, and it is. It's also how you get your first 10–20 users and your clearest feedback.

2. Show up where the problem is discussed#

Find the communities where your users talk about the problem — subreddits, Discord servers, Slack groups, niche forums, LinkedIn groups. Then:

• Help first. Answer questions about the problem, with or without your tool.
• Share when it's relevant, and say plainly that you built it.
• Read the rules. Most communities limit self-promotion; breaking the rules burns the channel for good.

3. Launch on a platform, properly#

A single, well-prepared launch can bring your first big wave of visitors. Pick one platform, prepare for two weeks, and be present all day. Our Product Hunt guide and launch checklist cover the details.

4. List on directories where people browse by task#

AI directory visitors are already looking for a tool. That's warm traffic — and it keeps coming long after a launch day ends. Start with 5–10 relevant directories from our list of 50+, and follow the submission checklist so each listing is done properly.

5. Build a free mini-tool#

A small, free, single-purpose tool related to your product can attract steady search traffic and links. For example:

• A meeting-notes AI → a free "meeting cost calculator"
• An image AI → a free "background remover for one image"
• An SEO AI → a free "title tag length checker"

Each one should do one job well, need no sign-up, and point naturally to your main product for the bigger job.

6. Write for the searches your users make#

Write a handful of pages that answer the questions your users type into Google and ask AI assistants:

• "How to [do the job] with AI"
• "[Competitor] alternatives"
• "[Tool A] vs [Tool B]" (be honest — fair comparisons build trust)
• "Best AI tools for [audience]" (yes, you can include your own, transparently)

Make these pages readable by AI assistants too — see our llms.txt guide.

7. Build in public#

Post regularly about what you're building: screenshots, small wins, numbers, mistakes. It gives people a reason to follow along, and when you launch, they show up. Short demo videos of the result your tool produces tend to travel furthest.

8. Partner with someone who already has your audience#

Newsletters, YouTubers, course creators and agencies already have the attention you want. Offer them something genuinely useful: free access for their audience, a co-written tutorial, or an integration with a tool they already use.

9. Make your first users your marketers#

• Ask happy users for a one-line quote you can put on your homepage.
• Add a simple referral perk (extra credits, a free month).
• Add "Made with [your tool]" to free-tier outputs where it's appropriate and easy to remove on paid plans.

10. Remove friction ruthlessly#

Often the fastest way to more users is to lose fewer of the visitors you already have:

• Let people try something before they sign up.
• Cut sign-up to email or Google only.
• Show a result in the first session — prefill an example if you have to.
• Make pricing visible and simple (pricing guide).

Keep the users you get#

Getting 100 users and keeping 10 is a common story. To avoid it:

• Email every new user personally in the first weeks. Ask what they were hoping for.
• Watch the first session. Where do people stop? Fix that first.
• Ship visibly. A short "what's new" note every week or two shows the product is alive.
• Talk to people who leave. One honest conversation with a churned user is worth ten surveys.

A simple 30-day plan#

Track one number above all: how many people reached your activation event this week. If that's growing, the rest follows.
