How to Find Untapped Audiences Without Wasting Spend

Everyone in growth talks about “scaling.” But here’s the part most people skip: if you’re scaling the wrong audience, you’re just paying to accelerate waste. The campaigns that actually compound are the ones that uncover the right new people to reach.

And no, you don’t need a bigger net - you need a sharper one.

Here’s how we usually approach it when we want to grow reach without burning budget:

1. Put Your Own Data to Work

The best audience insights are already in front of you: your CRM, your email list, your site visitors. Feed that data into Meta or TikTok lookalikes and you’ll surface people who behave like your top buyers. It’s a smarter play than guessing interests or chasing demographics that “might” fit.

2. Think in Overlaps, Not Buckets

Broad segments are lazy. “Eco-travelers” sounds good on paper, but drains ad spend fast. Add another layer—say, eco-travelers with high disposable income—and suddenly you’re talking to people who are both value-driven and able to pay for the experience. Those intersections are where scale and conversion meet.

3. Test in Slices, Not Surges

Expansion doesn’t mean doubling your ad set overnight. Start small: 5 to 10% of the budget, then watch what happens. Are CPAs dropping? Do retention curves improve? If the early data holds up, you’ve earned the right to spend more. If not, shut it down and move on. It really is that simple.

4. Match the Message to the Market

New audiences need new creative. What works on bargain hunters will flop on aspirational buyers. Change the angle, adjust the visuals, and rewrite the hook so it feels like their world. Audience fit isn’t just who you target, it’s what you say when you get in front of them.

The Takeaway

Expanding your reach isn’t about shouting louder, it’s about spotting the people already leaning in and speaking their language. Start with what you know, layer in intersections, test carefully, and scale only what sticks. That’s how you grow without gambling.
