Facebook Group Marketing Strategy: How Jenni AI Got Its First 100 Paying Customers

In the early stages of Jenni AI, founder David Park and his team faced the typical startup dilemma: zero marketing budget, no audience, and limited time.

Instead of cold outreach or paid ads, they took a slower—but much more effective—path: Facebook groups.

They used a thoughtful, human-first strategy that not only brought in their first 100 paid users but also helped them build a loyal community that felt personally invested in their success.

Step Into the Right Room: Join Niche Groups With Built-in Demand

They specifically targeted Facebook groups with 10,000 to 100,000 members. These weren’t just random internet forums—they were active, niche communities where real users hung out.

The key was to get in early, observe, and immerse themselves before ever mentioning their product.

Find the Influencers Who Quietly Run the Show

Inside each group, they identified the "power users": moderators, prolific posters, and people whose comments always got traction.

These individuals had invisible authority. Befriending them, even indirectly, was a multiplier for trust.

They made an effort to add genuine value. No ChatGPT-style replies. No vague, motivational content.

They posted thoughtful responses, shared personal experiences, and treated each post like an opportunity to help—not to gain followers or promote.

Conversations First, Products Later: Message Like a Human, Not a Bot

Once power users were familiar with them, they reached out privately. Every message was personalized.

No copy-paste intros. No formalities like "Dear sir or madam."

Instead, they referenced old posts, pointed out shared interests, or casually brought up mutual connections.

Don’t Sell. Just Talk. Then Actually Listen.

When they got on calls, they didn’t pitch anything. They asked.

They used techniques from "The Mom Test" to avoid leading questions. The goal was understanding pain points, not trying to validate an idea they already had.

These calls were friendly, unhurried, and curious.

Build Only What They Ask For, Not What You Imagine

After 10–20 calls, patterns emerged. Instead of building what they thought the market needed, they built what the users said they wanted.

Then they took it a step further: adding the user's name in the dashboard, referencing inside jokes, or even mocking up the tool around that person’s specific workflow.

The goal was simple—make it feel like a gift for a friend.

Share the Product Like It’s a Gift, Not a Launch

They didn’t launch to the public. They messaged users individually and said, "Hey, I made this based on our conversation. Let me know what you think."

Even when feedback was critical, they treated it as gold. Every suggestion was logged. Every complaint was respected.

Iterate Until One Person Can’t Stop Talking About It

They didn’t aim for 10 people to sort-of-like it. They aimed for one person to love it.

And when that person started using it every day, unprompted? That’s when they knew it was time to expand.

They asked that early superfan to write a post in the Facebook group. Not a testimonial, not a pitch—just an honest "here’s what I’ve been using" kind of post.

This created instant validation. It also made Jenni AI look co-signed by the group itself.

Grow by Listening: Turn Group Feedback Into Product Fuel

New users started trying the tool, leaving comments, and offering feedback.

This next wave of feedback was critical. It helped shape the product into something beyond just a personal solution.

And because it came from the group, people felt ownership in the tool’s evolution.

Become a Part of the Group’s Culture and Let Word of Mouth Create the Illusion of Scale

David and the team kept showing up. They continued replying to posts, answering questions, and sharing value—even when they weren’t talking about their product.

Eventually, they became known as contributors. Not marketers. Not lurkers. Just helpful peers.

As the tool got mentioned casually in conversations, other users began assuming it was a well-established product.

It became the "default tool" for certain workflows inside the group. And that perception created trust and natural demand.

Months later, David started getting DMs from new founders.

They were asking the same questions he had once asked: How do you get users? How do you validate?

Even though he was busy, he always replied. Because that’s the culture he wanted to keep alive.

There was no shortcut in this process. It wasn’t a tactic; it was a strategy based on care and commitment.

Jenni AI earned its first 100 users the hard way, and that’s exactly what made it sustainable.

Most people fail because they try to "infiltrate" too fast. Or they post like they’re on LinkedIn.

Don’t pitch early. Don’t fake friendships. And don’t be another shallow voice in a crowded feed.

Communities reward consistency, humility, and generosity.

Jenni AI didn’t grow because it had a better product. It grew because David Park and his team took the time to understand people, befriend them, and build something that solved their real problems.

And when users feel seen, they don't just become customers—they become advocates.

Humans are annoyingly consistent. What worked 10-15 years ago will work again today if you change the format.

If you listen to new music, you'll realize how much of it is just a remix of old songs.

The same is true with Disney movies from 1930s and 1990s.

When listening to marketing advice, don't listen to advice from marketers that were great 10 years ago.

This one is a terrible advice from great marketer. There are entire agencies that make accounts with zero followers go viral within 30 days.

Excellent prompt.
