It is **not** a SaaS product, marketplace, or company homepage for a single employer. Company sites live on external domains (especially durasius.com and corsius.com). **Positioning (from the site):** Work at the intersection of design, business, systems, and execution — brand, product, operations, and leverage. Preference for work with strong bones: clear ideas, clean execution, depth under pressure. Less noise and trend-chasing; more durable, compounding outcomes. --- ## Public pages (indexable) | URL | Purpose | |-----|---------| | https://durasjan.com/ | Home — hero, testimonials, overview, experience timeline, education, featured ventures, philosophy (four pillars), social follow, contact | | https://durasjan.com/about | Extended bio — who he is, how he thinks, experience timeline (`#history`), education, contact & follow | | https://durasjan.com/privacy | Privacy notice (minimal analytics, email contact, no accounts/forms) | | https://durasjan.com/llms.txt | This file | | https://durasjan.com/sitemap.xml | XML sitemap | Home section anchors (same page): `#testimonials` · `#overview` · `#experience` · `#ventures` · `#philosophy` · `#contact` About page anchor: `#contact` (Contact and follow) --- ## Ventures & organizations ### DURASIUS (holding / studio) - **URL:** https://durasius.com - **Legal name:** Durasius s. r. o. - **Founded:** 18 October 2024 (renamed DURASIUS October 2025) - **Contact:** contact@durasius.com - **Role:** Jan Duras — Founder & CEO (since Oct 2025) - **Summary:** DURASIUS builds products and businesses that solve real, everyday problems — properly.
