We raised a $3.5m CAD Seed Round! Open-source .NET FTW!
At Uno Platform, we pride ourselves on building cross-platform tools that are accessible to all .NET developers; from those building enterprise software to hobbyist curious about .NET and creating their first application.
Our seed round is a huge win for the .NET community and open source .NET, and it’s been recognized by TechCrunch and BetaKit – the leading tech startup outlets.
To continue innovating and bringing even more tools to Uno Platform, we are thrilled to announce that $3.5M CAD in seed funding has been raised! Led by AQC Capital and participation from Scott Hanselman, Microsoft’s VP of Developer Community and Angel investor, we are immensely grateful for the continued confidence our investors have placed in Uno Platform.
“I’ve followed Uno Platform’s impressive momentum for years—consistently inspired by their innovation in the .NET ecosystem and the vibrant, inclusive community they’ve fostered. As an angel investor in Uno Platform, as well as their technology advisor, I’m thrilled to support Uno Platform on its journey to becoming a flagship success in open-source .NET, equipping developers with tools that significantly elevate productivity.”
This round brings the total amount invested in Uno Platform to $6.5M CAD to date and marks a major step forward in our journey to become the most productive solution for cross-platform .NET developers

Why Raise a Seed Now: Market Shifts, Rising Developer Expectations, and the Growing Role of AI
You’ve probably noticed the buzz around AI and its promise to supercharge developer productivity. We are observing modern app development splitting into two different camps, as enabled by AI:
- The hobbyist, designer, or product manager building quick prototypes or disposable applications.
- The professional developer crafting complex, mission-critical, enterprise-grade applications.
At Uno Platform, we’re laser-focused on the latter, with a particular focus on the .NET ecosystem, and this seed round will allow us to bring Generative AI capabilities to Uno Platform Studio.
In addition, over the past year, we’ve seen growing demand from .NET developers and enterprises alike for:
- Cross-platform support without compromise, across mobile, web, desktop and embedded
- Visual Designers – such as our newly released Uno Platform Studio and patent-pending Hot Design which increases productivity and fills the long-existing gap in .NET development
- AI-enhanced workflows that assist developer when needed, charting our own AI course based on real value to software developers.
- Maintenable, production-grade code, that is easy to evolve from prototype to production grade application
While some tools in non-.NET world try to bridge these gaps, they often force trade-offs. Uno Platform approach will be different – our visual designer will soon get Generative AI-features all while providing full control of your code – all built on top of a robust open-source foundation.
Why We Started Uno Platform
Let’s rewind the clock a bit, to talk about where we came from, which explains the importance of this investment.
Modern applications rarely live on just one device. Users expect the same app to work seamlessly on mobile, desktop, and web—sometimes even on embedded systems. But for professional .NET developers, delivering that vision has meant juggling multiple codebases, frameworks, and toolchains. This resulted in bloated projects, slow-release cycles, and a constant battle to keep features in sync across platforms.
We built Uno Platform to solve this problem. Our goal was to make developers more productive by giving them a single, open-source codebase that compiles to native apps for every platform—without sacrificing control, performance, or access to the full power of the underlying OS. With Uno Platform, you can target iOS, Android, macOS, Windows, Linux and WebAssembly, all in C# and XAML. It’s a platform for developers who want speed, precision and maintainability – whether they are prototyping or developing production-grade applications.
What We’ve Done So Far
Since launching Uno Platform as an open-source project, our community has grown to thousands of developers worldwide, with hundreds of contributors to our GitHub repository. We’ve seen Uno Platform used everywhere – from Fortune 500 companies like Toyota to startups building new products from scratch to government and public sector organizations modernizing mission-critical systems.
Uno Platform now powers a broad range of applications: internal enterprise tools, customer-facing apps, migration projects from legacy, single-platform, technologies, and even migrations from Flutter and React Native.
And yes – We dog food!
Our technology is also the foundation for Uno Platform Studio, a suite of productivity tools including Hot Design—our patent-pending runtime visual editor that lets you bind live data, edit UI, and make changes instantly without recompiles or rebuilds.
Along the way, we’ve partnered closely with Microsoft to ensure first-class support for .NET, and we’ve invested heavily in application performance – culminating in our unified Skia rendering engine that delivers consistent, high-FPS UI across every platform.
As we grow, our mission remains clear: help professional developers build cross-platform .NET applications faster, with full control, and without compromise. And the momentum is real – over 130 million NuGet packages downloaded, and an open-source repo that is absolutely on fire!
Uno Platform 6.0 and Uno Platform Studio General Availability Was Just the Beginning
The seed milestone comes just months after our major release when we shipped:
- Uno Platform 6.0 – with a unified rendering engine (Skia) delivering up to 60% faster startup and a 75% smaller footprint, with major performance gains across Web, Mobile, Desktop, and Embedded
- Uno Platform Studio, our premium suite of developer tools — which brings visual design, real-time editing, and design-to-code workflows into your everyday development process, on the operating system of your choice, to an IDE you are used to working with.
Uno Platform Studio is already in market, supercharging pro developers’ workflows, and it will continue to evolve rapidly to use AI selectively where it truly helps developers.
- Hot Design: Our patent-pending visual code editor. Pause a running app, turn it into a live canvas, make UI changes, and resume — no rebuilds required. Hot Design is available today.
- Hot Reload: We believe this is the most complete Hot Reload experience in .NET – built to handle even the most complex UIs, so you can iterate on UI changes faster. Hot Reload is available today.
- Design-to-Code: A Figma plugin that turns designs into production-ready XAML and C#. Design-to-Code is available today.
- AI Integration Our Generative AI is coming soon
Built on Open Source. Powered by Developers.
Uno Platform is proudly free and open source, under the permissive Apache 2.0 license. Our core remains fully accessible to the community — no runtime fees, no limitations.
The sustainability model is simple:
