Every major software era has been defined by a new distribution surface
In the PC era, software distribution was intensely physical. Developers burned their code onto floppy disks and CD-ROMs, boxed them up, and fought for shelf space in brick-and-mortar retail stores. It was a high-friction, slow-moving process, yet it laid the foundation for the personal computing revolution and created the first great software empires.
Then came the Web era. The browser transformed distribution overnight by replacing physical media with the hyperlink. Suddenly, users didn’t need to drive to a store or wait for a lengthy installation wizard; anyone, anywhere, could access an application instantly via a URL. The internet eliminated the marginal cost of software delivery and shifted the battleground from shelf space to search engines and social feeds.
A decade later, the Mobile era fundamentally changed the paradigm again. The App Store and Google Play centralized distribution, placing software directly into the pockets of billions of people. Mobile wasn’t just a smaller screen; it introduced native push notifications, GPS, and always-on connectivity. It allowed developers to tap into users’ moment-to-moment lives, giving rise to entirely new categories of on-demand services and social platforms.
Each platform offered a new way to reach users, a novel distribution mechanism.
At Jest, we believe we’re at the beginning of a new chapter: the Messaging era.
Why messaging
Messaging is no longer just communication - it’s an interface.
From AI assistants to customer support bots, users have grown accustomed to interacting with technology through chat.
Jest builds on this shift by pioneering messaging apps - turning the native messaging inbox into a new distribution surface for interactive experiences.
Three structural advantages make this approach incredibly powerful:
- Universal - Messages come pre-installed on smartphones. Developers can reach iOS and Android users instantly through an interface they already use every day.
- Sticky - The messaging inbox is mobile’s most retentive surface. It’s where people stay in touch with friends and family. That level of daily engagement is something most app platforms can only dream of.
- New app-like superpowers - Messaging hit a structural inflection point in late 2024, when RCS became effectively universal across modern smartphones. The inbox transformed from simple text threads into an interactive, app-like surface.
Few people fully understand how significant this shift is - so let’s unpack what’s actually happening.
The RCS inflection point
In late 2024, Apple adopted RCS with iOS 18.
That decision changed the trajectory of messaging.
Until then, RCS was mostly an Android story. With iOS adoption, it became cross-platform by default - embedded inside the native Messages app on nearly every modern smartphone.
That interoperability is what turns messaging into a platform.
RCS upgrades the inbox from simple text threads to a rich, interactive, app-like surface - complete with verified brand identities, media, and structured actions.
And because it lives inside the built-in messaging app, distribution is instant.
RCS is now on track to reach 3.8 billion daily active users by the end of 2026.
This moment goes far beyond a feature release. We’re witnessing the foundation of a new application layer - one where messaging becomes the platform and entirely new interactive experiences can be built directly inside conversations. Gaming is the obvious first expression of this shift, given it represents more than half of the App Store’s economic activity.
SMS → RCS
When most people think about texting, they picture SMS: simple text threads tied to a phone number.
What’s easy to miss is that texting is being upgraded in place, without manual updates or installs.
RCS is rolling out rapidly across modern smartphones. No new apps. No new behavior. The Messages app simply becomes more capable.
The inbox shifts from basic text and links to a richer, interactive surface with verified identities, media, and structured actions.
Subtle in appearance, but transformative in capability.
| Feature | SMS | RCS for Business |
|---|---|---|
| Sender Identity | Phone number only | Verified brand name with checkmark |
| Branding | None | Logo, brand name, tagline |
| Media Support | Basic links only | High-resolution images, carousels, rich media |
| Interactivity | Manual replies (“Reply YES”) | Tappable buttons, suggested replies, structured actions |
| User Experience | Static text thread | Dynamic, app-like conversational interface |
| Trust & Verification | No authentication | Verified sender identity reduces spoofing |
| Analytics | Limited delivery confirmation | Read receipts, engagement tracking |
| Capability Level | Messaging channel | Programmable surface |
SMS made messaging ubiquitous.
RCS builds on that foundation by adding identity, interactivity, and programmability to a surface billions of people already use every day.
That combination creates the conditions for entirely new categories of software, including messaging apps and games.
Messaging apps are coming
Every major software wave has been driven by a shift in distribution, from PCs to web to mobile. Messaging represents the next structural unlock: a built-in surface with billions of users and zero install friction.
This shift gives rise to a new medium: messaging apps.
At Jest, we’re building the platform that enables, distributes, and scales messaging apps and games.
