SUMMARY
- Czech startup Supernova has secured $9.2 million in Series A funding to launch Portal, an AI-driven product development platform that helps professional teams accelerate workflows from ideation to code.
The funding round was led by Taiwania Capital and supported by J&T Ventures, Reflex Capital, Kaya, Credo Ventures, EQT Ventures, Wing VC, and Y Combinator.
Supernova will use the funding to expand its team, enter Asian markets with the support of Taiwania Capital, and scale both product development and marketing efforts.
Built on Supernova’s unified platform for design systems and code, Portal introduces “vibe-coding”, a new approach leveraging AI to streamline both routine and strategic tasks across the entire product lifecycle. Unlike prototyping tools such as Lovable and v0, Portal is designed to integrate seamlessly with enterprise workflows from start to finish.

“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 of Supernova. “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, so they can focus on creating exceptional products rather than getting bogged down.”
Portal tackles key product development challenges such as fragmented documentation, inconsistent handoffs, and resource bottlenecks. By integrating AI agents directly into collaborative workspaces, Supernova aims to close a critical efficiency gap that investors identify in modern product organizations.
Founded in 2018, Supernova helps teams build better products, faster. Its AI-powered platform, including Portal, simplifies the entire product development process from ideas to code by reducing bottlenecks, boosting collaboration, and speeding up workflows. Supernova enables product teams to scale efficiently while seamlessly integrating with existing enterprise systems.
