As answered by people managing Project Euler and SimpleAct.de.
SimpleAct.de's answer:
SimpleAct focuses on making AI governance and EU AI Act compliance operational instead of overly theoretical or enterprise-complex. While many governance platforms are built primarily for large corporations and consulting-heavy processes, SimpleAct is designed to give organizations a practical and structured way to manage AI systems, risks, governance workflows, incidents, audit evidence, and compliance activities in one centralized platform.
The platform combines AI inventory management, EU AI Act risk classification, governance workflows, operational controls, incident management, and audit documentation into a single workflow-oriented solution. This allows companies to move away from fragmented spreadsheets, disconnected documents, and manual compliance tracking.
SimpleAct is built to help organizations establish scalable AI governance processes that teams can actually use in daily operations — with a strong focus on clarity, usability, and practical implementation.
SimpleAct.de's answer:
Organizations choose SimpleAct because it focuses on practical and operational AI governance instead of overly complex enterprise processes. The platform helps companies manage AI systems, EU AI Act compliance, governance workflows, incidents, audit evidence, and operational controls in one centralized workspace that is designed to be understandable and usable in daily operations.
Unlike many competitors that are heavily consulting-driven or built primarily for large enterprises, SimpleAct emphasizes clarity, scalability, and implementation speed. Teams can quickly document AI systems, classify risks, manage approvals and governance workflows, track compliance activities, and maintain audit-ready documentation without relying on fragmented spreadsheets or disconnected tools.
SimpleAct is especially valuable for organizations that want a structured and scalable way to operationalize AI governance while staying flexible, efficient, and focused on real-world workflows.
SimpleAct.de's answer:
SimpleAct is designed for organizations that use or manage AI systems and need a structured way to handle AI governance, compliance, and operational oversight. The primary audience includes companies preparing for the EU AI Act, businesses operating high-risk AI systems, and organizations that want to establish scalable governance processes around AI usage.
Typical users include compliance teams, legal departments, risk and governance managers, IT and security teams, HR departments using AI-based recruiting tools, and operational teams responsible for internal AI initiatives or third-party AI vendors.
SimpleAct is particularly relevant for small and mid-sized businesses as well as growing enterprises that need practical AI governance workflows without the complexity of large consulting-driven enterprise platforms.
SimpleAct.de's answer:
SimpleAct was created to solve a growing problem many organizations are facing: AI adoption is moving faster than companies can realistically govern, document, and operationalize it. As new regulations such as the EU AI Act emerged, many businesses realized they lacked clear oversight of their AI systems, governance processes, risks, and compliance responsibilities.
Most existing governance solutions were either overly complex, heavily enterprise-focused, or too theoretical for practical day-to-day operations. Managing AI governance often meant relying on spreadsheets, disconnected documents, manual tracking, and scattered workflows across multiple teams.
SimpleAct was built to provide a more practical approach. The goal was to create a centralized platform that helps organizations operationalize AI governance in a structured, scalable, and understandable way. By combining AI inventories, risk classification, governance workflows, incident management, audit evidence, and operational controls into one platform, SimpleAct helps companies move from reactive compliance efforts to clear and manageable governance processes.
SimpleAct.de's answer:
SimpleAct is built as a Node.js monorepo for an EU AI Act compliance SaaS.
The backend uses NestJS (TypeScript) with Express, TypeORM, and PostgreSQL in production and tests (SQLite for local development). Authentication is handled with Passport and JWT, among other options.
The frontend is a React 18 single-page app bundled with Vite, styled with Sass, and written mainly in JavaScript (JSX).
Testing and delivery rely on Jest (backend), Vitest (frontend), Playwright (end-to-end), Docker with PostgreSQL, and GitHub Actions for CI/CD.
Important integrations include Stripe (billing), AWS S3 (file storage), and Nodemailer (email). A small Discord.js bot supports support workflows.
