Montréal-based AI software startup Uno Platform has secured $3.5 million in convertible note financing to assist enterprise developers in leveraging vibe coding while mitigating security risks.
The financing round was led by Québec-based AQC Capital, with contributions from Desjardins Capital, Oliva Capital, and over a dozen angel investors through Anges Québec, including Microsoft’s Scott Hanselman. This brings the startup’s total funding to $6.5 million.
“With consumer-facing vibe coding apps, what you gain in productivity, you lose in control,” said François Tanguay of Uno Platform.
Uno Platform has developed a coding assistant for software engineers to create apps for mobile, web, and desktop. Its launch coincides with the rise in vibe-coding, where AI tools generate code from plain-language prompts. The startup describes its product as “pragmatic” vibe coding, offering drag-and-drop tools while avoiding AI code “black boxes,” maintaining enterprise security standards.
Tanguay stated, “Enterprise developers need 100-percent visibility into how AI tools alter the source code.”
Uno Platform’s “Hot Design” visual coding feature is patent-pending, enabling developers to adjust designs in a live application, with instant updates in the underlying code.
The project started internally to enhance productivity at Montréal tech company Nventive. Made open source in 2018, it has garnered over 300 contributors. In May, Uno Platform launched a paid version with additional features for large enterprises on a subscription basis.

Vibe coding assistants like Cursor reportedly earn over $500 million in annualized revenue but face negative gross margins due to large-language models’ costs. These LLM creators also compete with vibe coding startups via consumer and enterprise offerings.
Tanguay mentioned Uno Platform is evaluating pricing for the AI models on its platform and might reduce costs by allowing customers to use their AI model subscriptions. AI adoption in Canadian businesses doubled from May 2024 to May 2025, indicating a growing market. The startup’s revenue remains undisclosed.
Uno Platform plans to use its funding to enhance its Studio product, execute its market strategy, and expand its team from 20 to 30 in Montréal. Current clients include Jean-Coutu, Cineplex, and iA Financial.
Tanguay praised the local investor ecosystem’s support, expressing delight in its energy.
“I’m not saying we won’t consider a Series A in the US or seek further partnerships there, but for now, we’re very satisfied,” he added.
