NaionX at sTARTUp Day 2026: Pitchin at Beyond Validation, Beyond the Obvious by BSV Ventures

NaionX is heading to sTARTUp Day 2026 to pitch in “Beyond Validation: Early Deep Tech Pitch Hour”—a session built for the kind of companies that are past the “does it work?” question and deep into the “how do we scale it responsibly?” reality. Powered by BSV Ventures, this pitch hour puts early deep-tech teams on stage where the audience isn’t looking for hype—they’re looking for signals: technical clarity, market pull, and a credible path from lab to impact.

Why this session matters for deep tech

Deep tech doesn’t move on vibes. It moves on proof, iteration, and the ability to translate complex R&D into something industry can adopt.

That’s what makes Beyond Validation a strong fit for NaionX. The session is designed for startups emerging from the frontiers of science—teams building the answers to tomorrow’s questions, not just polishing a slide deck for today’s trends.

What NaionX is bringing to the stage

At NaionX, we’re developing proprietary sodium-ion battery cell chemistry for both electrodes—an approach built around supply-chain security, sustainability, ethics, and safety, with a clear European focus.

In a battery world shaped by critical-material constraints and geopolitical risk, sodium-ion is more than an alternative chemistry—it’s a strategic lever. Our work is rooted in R&D originating from the University of Warsaw and strengthened through partnerships with European partnerships, with the goal of bringing Europe a stronger, more resilient energy storage foundation.

The real “beyond validation” question: adoption

Validation is necessary. Adoption is everything.

For battery innovation, the bar isn’t just performance in a lab cell—it’s manufacturability, reliability, and a business model that lets industry move fast without taking reckless risk.

That’s why NaionX is building toward a B2B licensing model in Europe: enabling battery cell manufacturers to adopt our chemistry and processes without reinventing their entire production stack. The aim is straightforward: help accelerate European energy storage capacity while keeping sourcing and sustainability principles intact.

See you at the Pitching Stage

If you’ll be at sTARTUp Day 2026, come find us at the Pitching Stage during Beyond Validation: Early Deep Tech Pitch Hour (powered by BSV Ventures).

We’d love to connect with:

• Battery cell manufacturers exploring next-gen chemistries

• Industry experts and scientists who want to pressure-test the approach

• Investors who understand that deep tech timelines can be ambitious and disciplined

Because the future of energy storage won’t be built by the loudest story—it’ll be built by the most credible one.
