# Shockworks > Stop renting software. Start owning. Shockworks builds custom software that replaces SaaS subscriptions — delivered with AI speed, human precision, and enterprise-grade SLA. Shockworks is a software studio that designs and builds custom business software to replace recurring SaaS subscriptions. Clients own the resulting code and infrastructure, eliminating per-seat fees and vendor lock-in. Typical engagements deliver 50–80% cost savings vs the SaaS alternatives over a 3-year horizon. The site publishes: - **SaaS Exit Playbooks** — guides for migrating away from specific SaaS tools, with ROI estimates. - **Our Work** — portfolio of delivered custom-software projects with case studies and savings achieved. - **Calculator** — interactive ROI tool for comparing custom builds to SaaS subscriptions. ## Pages - [Home](https://www.shockworks.eu/): Value proposition, hero, technical pillars, comparison vs SaaS. - [Playbooks](https://www.shockworks.eu/playbooks): Searchable index of SaaS exit playbooks. - [Our Work](https://www.shockworks.eu/projects): Portfolio of custom software projects with savings metrics. - [Contact](https://www.shockworks.eu/contact): Contact form for prospective engagements. - [Careers](https://www.shockworks.eu/careers): Open roles and culture. ## Resources - [Sitemap](https://www.shockworks.eu/sitemap.xml): Full list of indexable URLs including all published playbooks and projects. ## Optional - All financial figures use Euro (€) with European number formatting (de-DE locale). - The Shockworks calculator deliberately hides absolute prices and savings amounts from public view; it surfaces a verdict only ("Worth it" / "Not worth it") to protect commercial pricing.
