Supernova, a Czech-founded company that entered Y Combinator in 2019 and evolved from a design-to-code tool into a full product development platform, has launched Portal, an AI “vibe-coding” product aimed at speeding work from ideation to delivery. The rollout comes alongside a €7.85M ($9.2M) Series A led by Taiwania Capital, with participation from J&T Ventures, Reflex Capital, KAYA VC, Credo Ventures, EQT Ventures, Wing VC, and Y Combinator.
“We are proud to work together with Supernova, a company poised to define the future of product development,” said David Weng, CEO of Taiwania Capital. “Their architecture unifies design systems and code, enabling an AI-powered platform that goes beyond prototyping. Our investment also creates opportunities for Supernova in Asian markets.”
Positioned to cover the entire product lifecycle
Unlike prototyping-first tools such as Lovable or v0, Portal is positioned to cover the entire product lifecycle while keeping outputs aligned with a team’s existing standards and assets.
Built on Supernova’s architecture that links design systems with code — an approach the company has refined since its early design-handoff days — Portal targets long-standing bottlenecks: resource constraints, documentation drift, and slow cross-team handoffs.
“As an engineer and product leader who’s spent years in the trenches building and shipping products, I’ve seen firsthand how these bottlenecks bring teams to a halt ,” said Jiří Třečák, founder and CEO. “That’s why we’re launching this new product, to give individuals the power to ship like an entire team and enable full teams to push 10x faster.”
Portal embeds AI agents that draft and update PRDs, generate documentation, assemble stakeholder-specific business cases, and integrate with existing codebases — an extension of Supernova’s original mission to translate design into production-grade outputs. It connects to Figma, GitHub, and VS Code, pulling assets without changing established workflows, and uses design systems to produce high-fidelity prototypes, code, and docs consistent with team guidelines.
A Slack-style collaboration layer lets users assign tasks to AI agents — updating specs, syncing documents, or resolving inconsistencies in real time — reflecting Supernova’s shift from a single tool to a coordinated ecosystem for product work.
Growth story continues
The company says more than 400 organizations use its platform, over half of them enterprises, including Mozilla, KLM, Air France, Paramount, Kraft Heinz, Skyscanner, and LaunchDarkly; traction that grew as Supernova expanded from the Czech Republic to the U.S. market after YC.
“Supernova is doing for product development what Figma did for design giving teams a single place to collaborate and move fast,” said Tomáš Obrtáč, General Partner at KAYA VC.
Proceeds from the Series A will fund product development, hiring, and go-to-market expansion. While many employees work remotely, a Prague office will anchor product and new marketing capabilities. “We invested because Supernova addresses a costly gap in design-to-code translation, especially in legacy systems,” said David Polách, General Partner at J&T Ventures. “Automating routine design changes frees engineers for higher-value work.”
