The developers behind Shopify's $1.3 billion app ecosystem

Last year, Shopify paid out more than $1.3 billion to the developers who build across its ecosystem. To put that in perspective, when the Shopify App Store opened 15 years ago, it was a small directory of tools built by a handful of developers who saw something promising in a young ecommerce platform and decided to bet on it. 

Now the app store serves millions of merchants in virtually every category of commerce, and in the past year alone, active app installs across the ecosystem climbed nearly 20 percent. The developer economy that once ran on side projects and weekend work has become the most significant ecosystem in ecommerce. Behind every app is an entrepreneur who built a business by helping merchants sell, operate, and grow. And today, the success of countless stores hinges on what they've created.

But the $1.3 billion doesn't tell you what it feels like to build inside that ecosystem, what it takes to go from an idea to a first install to a business that changes your life and the lives of the merchants who depend on you. The stories do. 

A Lithuanian designer in Paris who failed at five startups before building a portfolio of Shopify apps that now generates $1.7 billion in additional revenue for his merchants. Three co-founders in Los Angeles who wondered why a Shopify store owner couldn't just text his customers and turned that question into a $100-million company. And a former Apple engineer in Chicago who built one of the first 100 apps in the Shopify App Store and has spent the last fifteen years proving that a small, intentional company can thrive alongside the giants, growing past $23 million in revenue without investors. 

That's the kind of opportunity that opens up when a platform and its developers work as partners in the same mission.

From freelancing to $1.7 billion in merchant revenue

Erikas Mališauskas had been designing Shopify stores for clients for years before he decided to start building apps for them. He was a freelance UI/UX designer—good at it, well paid—but he kept running into the same frustration: some of the solutions his clients needed didn’t exist yet. So in 2020, he partnered with a developer and decided to build his first app. He'd already tried and failed with five different startups. What kept him going, he says, was more than ambition. "It was never about the result. It was always about the process, the excitement and curiosity about building stuff and making your users happy."

Kaching Appz was the idea that stuck. The company builds upsell and bundling tools, apps that help merchants offer discounts. In a single year, the company went from roughly $900,000 to $4.3 million in annual revenue, entirely through organic growth. Today, Kaching Appz has a team of 40 and more than 100,000 merchants using its apps. Those merchants have collectively generated over $1.7 billion in additional revenue, a figure Erikas tracks closely because it represents the thing he cares about most. "I saw that there were stores making literally millions of revenue with an app they paid $60 for," he says. "It's a win-win-win. We're profitable. Shopify is benefitting. And our merchants are making more money."

The most vivid proof of that success is FK Žalgiris—one of Lithuania's most decorated football clubs—which Erikas has been a fan of since childhood. When the club became saddled with debt, Erikas and a group of local entrepreneurs stepped in to save it. He became a co-owner of the team, moved their merchandise onto Shopify, started using his own apps to run the store, and generated half of the previous year's merch revenue in the first couple of months. "I'm in the merchant's shoes now," he says. "When I use my own apps and see the impact, it feels really good."

The text that built a 9-figure company

Erikas found his opportunity in a gap he could see from the merchant's side. Alex Beller found his in a channel nobody was taking seriously yet. Postscript started with a question. In 2018, a friend of co-founder Adam Turner mentioned over lunch that he ran a Shopify store and wished he could just text his customers. At the time, Alex and Adam were working together at an ecommerce company, watching email engagement flatten while mobile shopping climbed. Something clicked. They recruited Adam’s brother Colin and launched a text message marketing platform exclusively for Shopify stores. "That core idea is still very much what we're working on today eight years later," Alex says. 

The decision to build only for Shopify was part strategy, part instinct. The three co-founders had originally imagined Postscript as a small, passive side business—maybe the first of several apps. That is not what happened. The SMS engagement numbers were impossible to ignore: click rates above 30% at a time when email was hovering around 1 or 2%. Staying focused on Shopify instead of pursuing shallow coverage across multiple platforms meant growing alongside Shopify's own expansion. "We were in the right place at the right time," Alex says. "If we'd tried to do SMS for everyone, it probably would have been way too spread out."

Today, Postscript serves more than 20,000 brands that use Shopify—from early-stage entrepreneurs to household names like True Classic, Ruggable, and Dr. Squatch—and crossed $100 million in revenue last year. "In the Shopify ecosystem, the bar for being merchant-first is uniquely high," Alex says. "We are extremely merchant-obsessed. And I think that's fueled a lot of our growth."

A philosophy experiment disguised as a software company

Isaac Bowen has been on Shopify since there was barely a platform at all. He built one of the first 100 apps in the Shopify App Store—a tool called Locksmith that lets merchants control access to specific products, pages, and content in their store. More than fifteen years later, it's still running, with more than 162,000 installs and roughly 16,000 active subscribers and 8-figure revenue. "Shopify felt like the first platform where people building it understood where the industry was going," Isaac says. "It was a developer-led design, and I didn't see that anywhere else."

Lightward's second product, Mechanic, lets developers wire up custom workflows without the burden of running their own infrastructure. Today, Mechanic powers 3,000 stores, processing six million actions a day, and its users include some of the biggest names in tech and entertainment.What makes Lightward unique isn't just the products. It's the people behind them. Isaac is autistic, and his husband and managing partner, Abe Lopez, has ADHD and OCD. The duo built Lightward specifically to work for how their brains operate, and that decision shaped everything about how the company operates. The team works asynchronously with almost no meetings. There are no arbitrary deadlines. Every employee's first job responsibility is their own health, the health of their teammates, then the product. 

"I don't give a f*** about the product if you're not taking care of yourself," Abe says. "Nothing is better if you're not healthy." Because of that philosophy, their team of 12 has seen zero percent employee turnover in ten years, and they now support more than 19,000 merchants with their apps. 

When asked what Shopify has gotten right about supporting developers over the long term, Isaac’s answer is immediate: keeping the conversation alive between the people building the platform and the people building on it. His VP of product and engineering Matt Sodomsky—who discovered Mechanic as a customer, fell in love with it, and eventually joined the company—puts it more plainly. "The more successful Shopify is, the more successful you tend to be. The rising tides have been floating the boats of all of us app developers."

What the builders know

Today, more than 21,000 apps and counting live in the app store. As AI accelerates the pace of change, merchants need more than raw capability. They need the people, products, expertise, and support that brings that capability to life. 

That's what the minds behind Lightward, Postscript, and Kaching Appz have always done: bring context, creativity, and trust on top of what Shopify builds. All three took different paths to success, but all arrived at the same insight: developers who last are the ones who never stop thinking about the merchant. The merchant is the mission. 

As Erikas puts it: "Sometimes you just need to talk to the merchant and ask what they need. Not what you want to make, but what they actually need." 

Shopify builds, developers build, and merchants benefit from the momentum both create. That's why this ecosystem remains one of Shopify's greatest strengths. With more merchants joining Shopify every day and innovation opening surface areas that didn't exist a year ago, the next chapter is wide open for the developers ready to write it.
