Supersonik Secures $5M to Launch AI-Powered Sales Demo Agent

San Francisco and Barcelona-based startup Supersonik has raised $5 million in a seed funding round led by Andreessen Horowitz, with participation from investors at Google, DeepMind, and Salesforce. 

Multilingual demos on the list of priorities following funding

The startup plans to use the funds to launch an AI agent that runs live, multilingual software demos for sales teams.

The company states that the AI agent can join video calls instantly and guide prospects through genuine software in real-time. It tailors presentations to the buyer’s company size, industry, and location, leveraging live data from CRMs, documentation, and knowledge bases. 

“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,” Daniel Carmona, CEO of Supersonik, said.

Addressing delays in modern software sales

Supersonik’s founders say traditional demos often slow down the sales process, especially for global or fast-moving buyers. The AI agent enables companies to offer immediate demos, reconnect with dormant leads, or automatically qualify prospects.

Unlike recorded demos, this approach responds dynamically to questions and interactions, aiming to make software demonstrations more efficient and personalized.

Joaquim Lechà, co-founder at Supersonik, lauded their efforts, stating that through the AI agent, they’ve built “a future where every company can engage buyers instantly, globally, and at scale, transforming how software is discovered and bought.”

Supersonik was founded this year by Carmona, Lechà, and Pol Ruiz, combining expertise in SaaS, AI development, and entrepreneurship. The company plans to double its workforce by the end of 2025, and will focus on engineering and customer-facing roles while strengthening the AI’s reliability for enterprise use.

The startup also intends to extend the AI agent’s capabilities beyond demos. The technology can support onboarding, renewals, and other customer interactions, enabling companies to respond instantly to buyer intent.
