TLDR: Barcelona-based startup Supersonik has officially launched from stealth mode, securing €4.2 million in seed funding.

Barcelona, Spain – September 4, 2025 – Supersonik, a Spanish startup, today announced its emergence from stealth mode, revealing a successful seed funding round of €4.2 million. The investment, spearheaded by Andreessen Horowitz and supported by notable angel investors from tech giants like Google, DeepMind, and Salesforce, will fuel the company’s mission to transform B2B SaaS sales through its innovative multilingual AI agent.
Supersonik’s core offering is an autonomous AI agent capable of joining live video calls, showcasing real software, and dynamically adapting product demonstrations to individual buyers in real-time and in their native language. This groundbreaking technology aims to eliminate common bottlenecks in the sales process, such as lengthy sales calls, manual scheduling, and language barriers.
Daniel Carmona, CEO of Supersonik, articulated the company’s vision: “Our vision is simple. Every prospect should be able to click a button and get a live, personalized demo of real software, in their own language, the moment they are ready. No forms, waitlists, or back-and-forth.” This approach allows B2B SaaS companies to deliver instant, interactive product experiences, enabling sales teams to focus more on closing deals rather than initial demonstrations.
Founded in 2025 by Daniel Carmona Serrat, Joaquim Lechà, and Pol Ruiz, Supersonik brings together a wealth of entrepreneurial experience, SaaS leadership, and technical expertise. Carmona Serrat and Ruiz had previously collaborated for three years on AI-driven automation, leading them to explore how AI agents could address the challenges of scalable and instant software demos. Joaquim Lechà, former CEO of Typeform, shared their conviction regarding the need for innovation in software sales, completing the founding team.
Supersonik is already collaborating with several companies prior to its public launch and has ambitious plans to double its team by the end of 2025. The newly acquired capital will be strategically allocated to bolster engineering and go-to-market efforts, alongside continuous investment in robust, compliant, and secure AI infrastructure. This ensures that their AI agents are not only reliable but also meet enterprise-grade standards.

Gabriel Vasquez, Partner at Andreessen Horowitz, commented on the investment: “Live demos have been too costly and slow for most SaaS companies to scale. Supersonik changes that by turning the sales process into an instant, interactive product experience that delivers real value from the start.” This sentiment underscores the potential impact of Supersonik’s technology on the broader SaaS industry.
