Flexibility is the key value we’ve taken from this cooperation. We chose nearshoring for the balance between cost and efficiency. Netcorp works best for organizations with a core team in place, and when scaling up from a small team, their services are ideal. I would recommend Netcorp’s services, as they fit the problem nicely and help tackle issues effectively, provided the client has a clear plan.

Petter Tancred Olsen
Nong & Petters CEO

Netcorp's developers helped us build out our software platform, and they did a fantastic job. They consistently delivered on time and within budget, and their communication was excellent throughout. What stood out was how proactive they were in finding solutions, often catching potential issues before we even noticed. We’re incredibly satisfied with their work.

Andri Vanem
Head of Software Development, Estonian Energy

Nowadays, finding good quality developers is a lot of work. Netcorp helped us ease that problem. Compared to other companies on the market, Netcorp offered developers who had really high standards, in the amount that was needed for us. Netcorp’s services can be described as very trustworthy. We get our responses very fast, and the profiles that we get prove their quality. Communication with them is very easy.

Aslak Os
CEO of Rocketfarm

Working with Netcorp felt like they were part of our internal team. They were always quick to respond and tackled every challenge head-on. Their technical expertise helped us meet our deadlines, and they were great at sticking to the budget we set. It’s rare to find a nearshore team that integrates so well. I highly recommend Netcorp for any software development needs.

Stein Wallevik
Dark Horse, Founder and Lead Stragetist

Netcorp has a ‘Scandinavian mind’ in their business approach, which helped address hesitations about working with companies from other cultures. Netcorp’s flexible model, allowing us to insource or offshore as needed, was the ideal solution.  It was a relief knowing we had this scalable, high-end group of resources, so I can focus more on technology development projects, confident I have great resources from Netcorp.

Urmo Aava
Ex-WRC Driver and Co-Founder of Rally Estonia

They are just like us: innovative, flexible, and fast. I wouldn’t recommend them to anyone, since we want to keep them to ourselves 🙂

Common questions:

Is Kotlin Multiplatform production-ready?

Yes, many companies use it for commercial Android and iOS apps, especially with stable KMM releases.

Can I integrate Kotlin Multiplatform into my existing app?

Absolutely. You can gradually adopt Kotlin Multiplatform in modular steps and integrate shared logic into your native codebases.

What’s the difference between Kotlin Multiplatform and Flutter/React Native?

Kotlin Multiplatform lets you share the core logic of your app—like data handling or network code—while still creating separate, fully native user interfaces for Android and iOS. This gives your app a true native look and feel.

Flutter and React Native use one shared codebase for both the logic and the UI. While this can be faster for development, it may not feel as smooth or natural on each platform as Kotlin Multiplatform does.

What is Multiplatform in Kotlin?

Kotlin Multiplatform is a feature of the Kotlin programming language that allows developers to share common code across multiple platforms—including Android, iOS, web, desktop, and backend—while still writing platform-specific code where needed. This approach helps reduce development time and maintenance costs without sacrificing native performance or user experience.

Is Kotlin faster than Java?

In most cases, Kotlin and Java have comparable performance because they both compile to Java bytecode and run on the JVM. However, Kotlin often enables more concise and expressive code, which can lead to fewer bugs and easier optimization. For native targets (like iOS via Kotlin/Native), performance depends on how the code is written, but Kotlin generally performs very well in real-world applications.

Is Netflix using Kotlin Multiplatform?

Yes, Netflix is among the companies that have explored Kotlin Multiplatform for sharing code between platforms. While not all of their systems are built with KMP, they have publicly discussed using it in specific projects to streamline development and maintain consistency across platforms.

When is Kotlin Multiplatform better than Flutter?

Kotlin Multiplatform is a better choice when your app requires fully native UIs on both Android and iOS, or when it needs deep integrations with native features and third-party libraries. It’s especially useful for projects that already have native codebases and want to adopt a cross-platform approach gradually.

How does Kotlin Multiplatform compare to React Native?

Kotlin Multiplatform shares business logic across platforms while allowing fully native UIs, whereas React Native uses a single codebase for both logic and UI with a JavaScript bridge to native components. KMP offers better performance and a more native feel, especially for apps that need platform-specific design or complex native integrations. React Native is often faster to prototype with, but KMP scales better for long-term, high-performance applications.
