“Talent wins games, but teamwork and intelligence win championships.” Michael Jordan

Chairman’s Message

Great technology. Check.
Committed people. Check.

Dais is making a difference in this world for two reasons: our proven nanotechnology and our dedicated team—everyone from my colleagues and investors to our suppliers and distributors.

This powerful combo intersects at Dais to protect the core elements of life. That’s it. And I’m certain you won’t find another tech company with a focus that clear.

I hope you resonate with that vision. That you want to use your time and resources to build a sustainable future. So, if that’s you…

You found us.

Our mission drives everything we do. It means we’ve focused on providing nanotechnology-based applications for large market applications in the energy and water industries since 1999. This is where I and the people of Dais can make the most difference in the world.

I congratulate you for considering Dais. It means you aspire to protect the core elements of life: fresh air, clean water, efficient energy.

The people at Dais are just like you.

Best regards,
Tim Tangredi
CEO and Chairman
