Supersonik, a Barcelona-based startup, has secured $5 million in seed funding to accelerate its mission of transforming how B2B SaaS companies sell their software. By leveraging AI-driven product demos that are instant, personalized, interactive, and multilingual, Supersonik is tackling one of the biggest pain points in SaaS: outdated and inefficient sales cycles.
Founded by Daniel Carmona Serrat, Supersonik is aiming to revolutionize the traditional go-to-market (GTM) model by merging discovery, qualification, and demonstration into one seamless, AI-powered experience. Instead of lengthy back-and-forth scheduling and human-led demos, prospects can instantly interact with AI agents that provide tailored product tours at scale.
This bold approach promises to shorten sales cycles, increase conversion rates, and give SaaS companies a competitive edge in an increasingly crowded market.
Rethinking the SaaS Sales Experience
B2B SaaS sales have historically relied on a linear model: discovery calls, qualification, scheduling demos, follow-ups, and then, hopefully, a contract. This approach worked in the early years of SaaS but has since become a bottleneck.
Modern buyers expect speed, personalization, and autonomy. They don’t want to wait a week for a demo - they want real-time answers, personalized value props, and a hands-on experience right when interest peaks. Supersonik’s AI agents deliver exactly that, collapsing multiple steps into a single dynamic interaction.
For SaaS founders, this shift isn’t just about efficiency - it’s about aligning sales with buyer psychology. Today’s buyers want to feel in control of the process, and AI-driven demos enable that sense of agency while still guiding them toward conversion.
The Breakthrough Behind Supersonik
Supersonik’s AI agents can:
- Automate personalized demos in multiple languages.
- Qualify leads dynamically, ensuring sales teams focus only on the most promising prospects.
- Deliver real-time interactivity, answering questions on the spot without human intervention.
- Scale globally without the friction of manual demo scheduling.
The technology is designed not just to mimic human sales reps but to augment them - freeing sales teams to focus on closing deals and relationship-building rather than spending countless hours repeating the same demo scripts.
Why AI-Driven Demos Could Reshape SaaS GTM
Here’s where the deeper insight comes in: one of the most overlooked leverage points in SaaS isn’t the product itself but the sales motion efficiency.
The highest-performing SaaS companies don’t necessarily have better features than competitors; they move faster in getting value in front of prospects. By optimizing how demos are delivered, Supersonik is attacking a blind spot many founders miss.
Think of it this way: in a typical SaaS funnel, every extra touchpoint creates friction. Friction causes drop-offs. If you can reduce the number of touches between interest and conversion, the compounding effect on revenue is massive.
This is why rethinking the demo stage is more than just a process tweak - it’s a growth multiplier. Startups that recognize this earlier can scale faster with the same sales headcount, giving them more efficient capital use and a shorter path to profitability.
The Founder’s Edge
Supersonik is led by Daniel Carmona Serrat, who brings both technical and entrepreneurial firepower. His background includes aerospace engineering, multiple international hackathon wins, bootstrapping a company to over $15M ARR, and going through Y Combinator’s Summer 2022 batch.
This unique blend of technical rigor and startup execution gives Supersonik an edge in tackling the complex challenge of blending AI with enterprise sales motions. Carmona’s experience signals that Supersonik isn’t just chasing hype - it’s being built with the discipline and resilience needed to scale.
AI in B2B SaaS: The Larger Trend
Supersonik’s raise is part of a broader wave: AI-driven tools are rapidly penetrating every layer of SaaS operations. Sales and GTM in particular are ripe for disruption.
Key trends include:
- AI as a sales co-pilot: Tools like Gong and Outreach are augmenting reps with insights, but Supersonik takes it a step further by replacing entire demo steps with intelligent agents.
- Global scalability: With multilingual AI demos, SaaS companies can instantly serve prospects across geographies, reducing the need for large region-specific sales teams.
- Self-serve buying journeys: According to Gartner, by 2025, 80% of B2B sales interactions will occur in digital channels. Supersonik’s model aligns perfectly with this shift.
Market Outlook: AI-Powered SaaS GTM
The opportunity Supersonik is addressing is enormous. Consider these industry signals:
- The global SaaS market is projected to reach $908 billion by 2030, growing at a CAGR of over 18%.
- Sales automation software is forecasted to exceed $7 billion by 2027, reflecting massive demand for tools that streamline GTM.
- According to McKinsey, AI can increase sales productivity by up to 50% - and companies that adopt AI in sales early will capture outsized market share.
- A 2024 Forrester report found that buyers who experience instant, interactive demos are 60% more likely to convert than those who wait for scheduled ones.
Supersonik’s $5M seed round positions it to ride this wave, creating a platform that could become foundational for SaaS sales teams worldwide.
What’s Next for Supersonik
With its new funding, Supersonik will likely focus on:
- Scaling its AI infrastructure to handle enterprise-level demo demands.
- Expanding its feature set beyond demos to potentially include onboarding, training, and customer success automation.
- Building partnerships with SaaS companies looking to modernize their GTM.
- Hiring top AI talent to stay ahead in one of the most competitive sectors in tech.
If executed well, Supersonik could position itself as the go-to platform for AI-powered SaaS sales, reshaping the way companies acquire and engage customers.
Final Thoughts
The SaaS world is crowded, but Supersonik is solving a problem so fundamental - and so overlooked - that its impact could be disproportionate to its stage. By collapsing discovery, qualification, and demonstration into a single AI-driven experience, it removes friction from one of the most critical points in the funnel.
Backed by $5M in seed capital, Supersonik is betting that the future of SaaS sales is instant, personalized, and scalable. If that bet pays off, it won’t just reshape SaaS GTM - it will redefine how software is sold in the digital-first era.
