Cash App: how Block turned a P2P payments app into a participatory event

Where P2P payments were in 2013

In 2013, Venmo (acquired by PayPal in 2012) was the default P2P payments app in the US. The category was defined: phone-to-phone payments between friends, with a social feed that showed who paid whom and for what. Venmo had a substantial first-mover advantage and a strong user base in young urban professionals.

Square launched Square Cash in October 2013 as a more stripped-down alternative. The original product didn't have a social feed and didn't try to compete with Venmo on its existing axes. It was a simpler tool: send money with a debit card, get money to a bank account. For the first few years, it was a useful but not particularly distinctive product in Venmo’s shadow.

The brand-voice pivot

Sometime around 2017-2018, the Cash App team made a series of decisions that changed the brand’s trajectory. The team developed a distinctive brand voice — irreverent, web-native, slightly absurd — that was unlike anything in fintech. They introduced $Cashtags, a public username system that was uniquely Cash App and gave users a piece of brand-affiliated identity. And they started running Cash App Friday, a weekly Twitter giveaway that turned the brand into a participatory event.

A few choices made the brand voice work:

• $Cashtags gave users a public identity. Unlike Venmo’s private payment-IDs, $Cashtags were public usernames people could share, customize, and use to receive money. The format itself ($Username) became a piece of internet vernacular.
• Cash App Friday created a recurring moment. Every Friday, Cash App ran a Twitter giveaway. Users replied with their $Cashtag, the brand picked winners, and people checked in every week. The cadence built a participatory rhythm fintech competitors didn't have.
• The voice was actually weird. The brand’s social copy, customer-service replies, and broader marketing felt like a person rather than a bank. The willingness to be strange in a category that defaults to corporate-safe was itself a differentiator.
• The product was reliable. None of the brand work would have mattered if the payments product had been unreliable. Cash App invested in product quality alongside the brand voice; the two together is what kept the experience coherent.

What grew, and what came with it

Cash App grew through the late 2010s and into the 2020s at a faster rate than Venmo. By 2024 it had about 57 million monthly transacting active users globally. The product expanded beyond P2P into a broader financial-services platform: direct deposit (Cash App Card), stock trading (Cash App Investing), Bitcoin, and tax filing through the Cash App Taxes acquisition.

The brand voice has remained consistent across the decade. Block changed its corporate ticker from SQ to XYZ in 2025 as part of broader corporate-identity work, but Cash App's brand voice and social-media presence have stayed in roughly the same register since 2017-2018. The consistency is part of why the brand has continued to compound — users know what Cash App sounds like, which is rare in fintech.

What other fintech brands tried to copy

Several fintech brands have tried to develop more distinctive social-media voices over the past few years. Some have worked (Chime's social presence, certain neobank brands). Most haven’t produced comparable engagement, for a few reasons:

• Approval chains were too long. Even brands that hired a “voice” lead usually still required marketing-and-legal sign-off on every post, which killed the timing and the weirdness.
• No recurring moment. Cash App Friday is a weekly cadence people plan around. Brands without an equivalent recurring touchpoint produce engagement only when they happen to post something good.
• No distinctive identity asset. $Cashtags became a piece of vernacular. Most fintech competitors have nothing comparable — their usernames are just account numbers.
• The product wasn't good enough. Brand voice can’t cover for an unreliable product. Cash App invested in reliability alongside brand voice; competitors that focused on voice without product investment lost users when the experience didn't hold up.

How RGM thinks about brand voice in commodity categories

When clients ask whether they should build a Cash App-style brand voice, the first question we ask is whether the category is actually commoditized enough for voice to matter more than features. If the product genuinely differentiates on capability, voice is decoration — helpful but not load-bearing. If the product is at parity with competitors, voice can be the primary differentiator — but only if the organization commits to it consistently for years and gives the voice-owner enough latitude to be actually weird.

The Cash App case is also a reminder that the product has to be reliable. Brand voice is a magnifier — it amplifies whatever experience the product produces. If the experience is bad, voice amplifies the badness. We tell clients that voice work has to come after product reliability, not before, and that the two have to keep pace as the company scales. Most brands that try to build voice on top of an unreliable product end up with louder complaints, not more brand equity.
