A private holding company, founded by Jan Duras, building and operating ventures with enduring standards. We design and build company websites through Durasius Websites — the Website Sprint — so real-world businesses stay visible, trusted, and properly online.
Mission
Durasius builds products and businesses that solve real, everyday problems — properly.
And when something deserves to exist simply because it can be done better, we build that too.
No borrowed opinions. No unnecessary complexity. Just clear standards, strong taste, and the discipline to get it right — and keep improving it until it holds.
We don’t chase trends. We build what still matters in five years.
Quality compounds. Cutting corners is borrowing trust at a rate we refuse to pay.
Built to outlive us. Measured in decades, not quarters.
Ventures
Built to make things work as they should. Earn back time, trust, or revenue.
The Website Sprint.
Our live client service: a complete company website designed and built to clear standards. Structure and copy shaped from your materials, then shipped as a durable site you own.
Portfolio

Founder
Jan Duras
Founder & CEO, DurasiusJan Duras (Ján Ďuraš) — founder of Durasius and Durasius Websites.
Jan started building things at 8 years old — not for attention, but because he genuinely enjoyed both the process and the result.
What began as curiosity turned into obsession. Design, video, code, product, marketing — whatever it took to bring ideas into the world properly.
Over time, that work became valuable. As an external B2B services partner — through his own companies and later Durasius — he delivered product design and marketing for CANNYPACK (Slovak software company based in Bratislava) and its products MODOC (world's leading “Anti-doping done right.” — end-to-end digital anti-doping SaaS), and LEAP ERP (all-in-one CRM and ERP for services businesses). Durasius continues those client engagements today.
He helped co-found TechGuru SK/CZ back in 2017 and became a creative mastermind behind the brand, from brand identity, through building the website, and all the way to marketing — eventually taking the brand under the “Powered by Durasius” umbrella as a portfolio project.
He shot numerous videos, crafted more than 1000 designs, coded multiple pieces of software, and continued on creating passionately, instinctively. All leading to gathering the most invaluable thing — taste. By building for others and delivering results — he saw how often things were rushed, compromised, or done without real standards.
That's where the line was drawn.
He founded Durasius in October 2024 (originally named The Whizziest) to build things the right way — with clear standards, strong taste, and independent judgment — and leads Durasius as CEO. The company was renamed to Durasius in October 2025.
No borrowed opinions. No compromises. Just the work, done properly, and improved until it holds.
The first product founded and launched under Durasius following these principles was Durasius Websites — a complete company website designed and built to clear standards through the Website Sprint.
This is just the beginning.
