Mathieu Marchis Spent Seven Months on His First App and Two Weeks on His Third

Everything shifted for Mathieu Marchis (Matt) when a friend introduced him to AI developer tools. For Matt, the decision to reject a traditional corporate path was clear long before he began coordinating cross-border engineering teams or pitching venture accelerators. High school classes came naturally, but standard coursework lacked the raw intensity and real-world stakes he craved.  After discovering AI developer tools, Matt spent seven days in his chair working 17 hours a day, teaching himself software development.

"I enjoy sitting down and feeling the tiredness and the pain and still working through it. That’s when I figured out I wanted to be a founder." 

Learning How to Build Through Rapid Iteration

Matt’s early initiatives served as a masterclass in direct execution. Seven months ago, without any formal background in software architecture or automated developer tools like GitHub, he manually copied code line by line from text prompts into Visual Studio folders. His first major build, a comprehensive fitness tracking app, required seven months of continuous iteration. However, upon recognizing that the fitness market was crowded and lacked a distinct value proposition, he made the mature decision to pause development rather than launch a generic product. Applying those lessons, he identified a clear niche in consumer skincare and launched Solace Skin within three months, using AI to quickly scan skin conditions and create personalized daily routines that generated immediate revenue as a solo founder.

Pressure-Testing Startup Workflows at LaunchX Entrepreneurship Program

During his time in the LaunchX Online Entrepreneurship Program, Matt stepped up as lead backend developer for a team spanning four countries and time zones. The program’s daily check-ins simulated the real-time discipline of an active startup accelerator, keeping everyone accountable through tight deadlines. When market feedback required strategic pivots, transitioning their concept three times from a landing page builder into a custom website conversion agency, the team adapted seamlessly and generated real revenue within the program window. Frameworks from LaunchX lectures combined with advanced AI tools allowed him to sharpen his ability to build, delegate, and manage cross-functional operations with the team.

Flipping Traditional Learning with Noura and the Protégé Effect

That momentum led directly to his role as Chief Technology Officer at Noura AI, co-founded alongside a global team across Malaysia, Australia, Poland, Romania, and the US. Operating under the core belief, "If you can teach it, you know it," Noura leverages the psychological principle of the protégé effect to completely invert traditional study habits. Instead of relying on passive AI tutoring, the platform positions the student as the instructor, requiring users to explain concepts to an AI model that intentionally makes errors. This structural dynamic forces students to spot errors, articulate core principles, and master complex subjects. Within two weeks of development, the team shipped a fully functional platform, expanded an organic waitlist of 70 early-access users, onboarded 60 creator accounts, and finalized applications for Y Combinator.

From Building Foundations to High Velocity Execution

Matt’s journey shows how real grit speeds up founder execution over time. By cutting his development timeline from seven months of manual coding on the first app down to just two weeks for Noura AI, he proves that momentum comes from fast iteration.

LaunchX gave Matt the high-pressure environment to turn raw discipline into structured startup systems. As Noura AI grows globally, he shows that when focus meets fast execution, young founders can move from an initial idea to scaling a venture at impressive speed.
