The Power of Growth Hacking Culture

A few years ago, sending money digitally was pretty tedious.

You had Venmo, PayPal, and maybe Zelle, but none were exciting.

They all were just tools, like an online version of your bank.

Then, Cash App came along and flipped the traditional online payments. Instead of acting like another finance company, they created the cultural movement.

• They partnered with rappers. (Did you see any fintech brand do this?)

• They made Bitcoin giveaways go viral.

• They turned social media into a free marketing machine.

The result is the exploded growth. Today, it’s one of the top players in P2P payments, competing with fintech giants with decades of history.

But here’s the thing. All this was neither luck nor overnight success.

It was strategy.

The Big Idea:

Building More Than Just a Payment App

Most fintech apps focus on security, ease of use, and speed.

Important? Yes. But exciting? Not really.

Cash App knew that it needed more than just a good product if it wanted to dominate. It has to be a brand people love.

So, Cash App did three things differently:

• Turned referrals into viral giveaways. Instead of boring cash-back deals, it gave users free Bitcoin to create instant hype.

• Embedded itself in hip-hop culture. While Venmo tried to be sleek and corporate, Cash App got shoutouts in rap songs and partnered with artists like Travis Scott and Megan Thee Stallion.

• Mastered social media engagement. It ran weekly X giveaways, got people to tag friends, and turned users into free promoters.

This wasn’t about promoting another payment method. Cash App made sending money cool. It made users feel like they were part of something bigger.

And that’s why it won.

So, how did the Cash App master those three things?

Behind the Magic:

Cracking the Code to Explosive Growth

Cash App grew by engineering growth.

It didn’t burn billions on ads like PayPal.
It didn’t rely on partnerships like Zelle.

Instead, it hacked human psychology, culture, and social media virality to dominate peer-to-peer (P2P) payments. And here's how it did.

1. They Made Referrals a Viral Growth Engine
(But Smarter and Strategic)

Every fintech app has a referral program. Most follow the same principle: invite a friend and get a few bucks. It’s transactional. Boring. Forgettable.

Cash App flipped this into something exciting, aspirational, and viral by offering free Bitcoin instead of just cash. Read this, for example:

And there are reasons why it worked:

• It’s not just free money but an asset.

  When someone gets $5 in Bitcoin, they don’t see it as just $5. They see it as their entry into investing, making them feel wealthier.

• Bitcoin is volatile, and that creates excitement.

  If Bitcoin rises, that $5 turns into $10. This creates a strong emotional bond with Cash App because people feel like they WON.

• People talk about free Bitcoin.

  If you give someone $5 cash, they will use it and forget it. But if you give them $5 in Bitcoin, they will check it daily and speak about it.

And there are a few reasons why this worked so well:

1. Psychological ownership: When people get free Bitcoin, they are more likely to hold onto it and use the app to track it.

2. Word-of-mouth marketing: Because Bitcoin was exciting, people bragged about their free Bitcoin, which attracted even more users.

3. A stepping stone to investing: Many users who got free Bitcoin stayed on the Cash App to invest more.

How You Can Use This Strategy?

• Instead of offering cash discounts, give away something valuable and aspirational.

• Choose a reward that ties users emotionally to your brand (e.g., Bitcoin made people feel like investors).

• Make the reward talk-worthy. If people don’t tell their friends, it won’t spread.

If you run a SaaS tool, you could offer a premium feature unlock for referrals instead of just a free trial. It is something that makes users feel special.

2. They Embedded Themselves in Hip-Hop Culture
(Instead of Running Boring Ads)

Most fintech brands try to be trustworthy and secure in their marketing. But Cash App went for cool, cultural, and viral. They became part of the culture by leveraging hip-hop, where money, status, and influence drive behavior.

Instead of spending millions on ads, it partnered with hip-hop artists to create deep cultural integration. Although it is the first time any fintech brand has done this so well, there are reasons for its success:

• Celebrity giveaways felt personal.

  Cash App didn’t just sponsor influencers but embedded itself into their lifestyle. Rappers like Travis Scott and Megan Thee Stallion ran Cash App giveaways from their accounts and made it feel organic.

Here’s a post by Travis Scott:

And this by Megan Thee Stallion:

• Name drops in songs = free marketing.

  When artists like Lil Durk and Future rapped about Cash App, it became a status and wealth symbol. Since then, fans didn’t see it as just another app but as part of the hip-hop lifestyle.

Check out the “All Love” song by Lil Durk - Lil Durk raps "I'm Cash App-in' a couple hundred whenever my brother call.”

• Merch drops created exclusivity.

  Cash App partnered with hip-hop artists to release limited-edition merch (like Travis Scott’s Cash App-branded T-shirts). These drops sold out instantly and turned it into a brand people wanted to be associated with.

What do you think contributed to this strategy?

1. Hip-hop influences youth culture. If a rapper endorses something, it instantly gets credibility.

2. It created brand aspiration. People didn’t just use Cash App but wanted to be part of the movement.

3. It felt organic, not corporate. Fans saw it as something their favorite artists actually used.

How You Can Use This Strategy?

• Don’t just sponsor influencers - embed your brand into a culture.

• Work with people your audience already admires (not just any influencer).

• Make partnerships feel authentic and aspirational. Do not just slap your logo on things.

For example, If you run a SaaS tool, don’t just sponsor an entrepreneur but get them to use your product publicly. That builds trust and credibility.

3. They Mastered Social Media Virality
(Without Spending Millions on Ads)

Most brands treat social media like a billboard - posting content and hoping people engage. Cash App saw it as a game in which users weren’t just followers but active participants in their marketing.

A few things the brand has done added up to this are:

• #CashAppFriday was a genius giveaway strategy

  Every Friday, Cash App gave money to random Twitter users who tweeted with #CashAppFriday. To enter, users had to follow the Cash App, retweet the giveaway, and tag friends (this created an exponential viral loop).

Check out this announcement on their Instagram:

And this on Twitter (now X):

• User-generated content = free marketing

  People started posting TikToks and tweets showing their Cash App balances after they got money. This made others want to join, which turned social media into a constant promotion machine.

• Gamification to boost engagement

  Some Cash App giveaways needed users to answer questions, share experiences, or complete challenges, not just retweet. This made giveaways more interactive and increased participation.

Now, this strategy worked super well because:

1. It turned users into promoters. People tweeted about Cash App every week to win the giveaway.

2. It created anticipation. Users looked forward to Fridays, which kept them engaged with the brand.

3. It cost very little. Compared to traditional ads, this strategy delivered millions of impressions at a fraction of the cost.

How You Can Use This Strategy?

• Create a giveaway that incentivizes engagement, not just like & share, but actual participation.

• Make social media feel like an interactive event, not just a marketing channel.

• Use giveaways to keep users engaged over time, not just a one-off promo.

If you run a newsletter, you can do a weekly challenge where subscribers share their favorite insights from your content for a chance to win a premium resource.

Cash App didn’t win because they had a better payment app. They won because they understood what makes people talk, engage, and feel part of something bigger.

And that’s the real growth hack.

So ask yourself:

1. How can I make my product more aspirational?

2. How can I make my audience feel they are part of something exclusive?

3. How can I create social loops that drive viral engagement?

When you start thinking like this, your brand stops being a tool and becomes a movement.

Where It Fits:

Making It Work For You

We have broken down how Cash App used referrals, culture, and social media to dominate P2P payments, but the question is:

How can you use these strategies to grow your own business?

» Make Your Referrals Irresistible

Instead of offering a boring $5 referral bonus, Cash App gave away Bitcoin to make users feel like investors. Therefore, you can:

• Choose a reward that excites people - something that makes them think they are getting access to something bigger.

• Make it aspirational - give away something users will brag about, not just a small discount.

• Gamify referrals - instead of a flat payout, create levels (e.g., refer 5 friends, unlock a premium feature).

Instead of offering a $10 credit for referrals, give users limited-time access to premium features when they invite friends.

Instead of giving away generic PDFs, reward referrals with exclusive behind-the-scenes insights or a 1-on-1 consulting session.

» Leverage Organic Influencer-Led Growth

Instead of running direct ads, they embedded themselves in hip-hop culture to make the brand aspirational. Likewise, you can:

• Find influencers who already love what you do - don’t just pay for random sponsorships.

• Integrate naturally - make sure influencers use your product in ways that feel real.

• Tap into micro-communities - find small but highly engaged creators instead of chasing huge influencers.

Instead of paying influencers for boring shoutouts, give them free lifetime access and let them showcase how they use your product.

Work with creators who use your product daily and get them to document their experience instead of just promoting it.

» Use Social Media as a Viral Growth Engine

Cash App created #CashAppFriday, where users had to engage with the brand on social media to enter giveaways. You can do this by:

• Turning your audience into promoters - design contests where engagement leads to more visibility.

• Making participation fun - don’t just ask for likes and shares. Get people involved creatively.

• Create a weekly or monthly ritual - something that keeps your audience coming back consistently.

Run a weekly Growth Challenge where users share their best marketing or business insights in exchange for a free premium subscription.

Run a Subscriber Spotlight where your most engaged readers get featured (and rewarded) every month.

» Make Your Brand Culturally Relevant

Cash App made the brand a status symbol by embedding itself in music, merch, and social conversations. Similarly, you can:

• Find a cultural niche that aligns with your product - don’t try to be for everyone.

• Use language and visuals that reflect your target audience’s world.

• Think beyond transactions - create a brand identity people want to be part of.

If your SaaS targets bootstrapped founders, don’t market like a corporate brand. Speak the language of indie hackers. Use memes. Be relatable.

If you sell productivity tools, don’t just push features. Make it part of a bigger lifestyle. Show real people using it to change their habits.
