Supersonik breaks the round barrier, raises $5M for AI that delivers instant software demos

Supersonik has raised $5 million in seed funding led by Andreessen Horowitz, a prominent Silicon Valley venture capital firm, to develop an AI agent that delivers live, multilingual software demos on demand. The San Francisco and Barcelona-based startup aims to eliminate the typical wait times for sales demos by offering instant, personalized product walkthroughs that adapt to each prospect’s needs in real time.

What you should know: Supersonik’s AI agent provides immediate access to live software demonstrations without requiring prospects to fill out forms or wait for human sales representatives.

• The AI shares its screen and guides prospects through actual products, pulling context from customer relationship management systems (CRMs), websites, and knowledge bases to customize each demo.
• The agent speaks in multiple languages and adapts conversations in real time based on the prospect’s specific interests and pain points.
• Onboarding a new product typically takes one to two weeks, after which the AI can highlight key features and connect to internal documentation.

The founding team: Serial entrepreneur Daniel Carmona Serrat co-founded the company with former Typeform CEO Joaquim Lechà and longtime collaborator Pol Ruiz.

• Carmona, an aerospace engineer by training, previously launched ventures in 3D printing software-as-a-service, demand forecasting for consumer packaged goods companies, e-commerce automation, and real estate tech.
• His pattern involves automating operationally heavy industries, but with Supersonik he decided to make AI the product itself rather than just an internal tool.

Why this matters: The funding addresses a costly bottleneck in software-as-a-service sales cycles where buyer expectations for instant access clash with traditional demo scheduling processes.

• “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,” Carmona said in an interview. “No forms, waitlists, or back-and-forth.”
• Andreessen partner Gabriel Vasquez noted that “live demos have been too costly and slow for most companies. Supersonik changes that by turning the sales process into an instant, interactive product experience.”

How it works: The AI agent focuses attention on the product itself rather than trying to mimic human sales representatives.

• Buyers hear a synthetic voice while the AI shares its screen, avoiding potentially unreliable human-like avatars.
• The system is trained thoroughly on customer pain points, workflows, and objection handling to ensure effective demonstrations.
• The AI can identify specific features prospects care about and discuss relevant use cases during the demo.

Growth plans: The nine-person team plans to double headcount by year-end and expand primarily in the U.S. market where most clients are based.

• The company is already working with undisclosed customers and will use seed funding for engineering and go-to-market hires.
• Beyond demos, Carmona sees opportunities for the same AI agent to guide customer onboarding and provide interactive support.

What they’re saying: Industry leaders see broader implications for how AI will reshape buyer expectations in sales processes.

• “The fastest way to lose a deal is to make a buyer wait,” Carmona concluded, suggesting buyer impatience will only accelerate in the age of AI.
• “The technology applies to so many things,” Carmona said about expansion opportunities. “We definitely believe we can build something massive.”
