Next generation requirements management software delivered by Stell meets the needs of highly-complex and regulated industries. Crafted by aerospace engineers, Stell can transform static documentation into actionable workflows, all while focusing on U.S.-based security, cross-team collaboration, and cutting-edge simplicity.

Why Aerospace Teams Choose STELL Over Legacy Tools

Aerospace engineers teamed together to create a platform for simplifying the chaos of traditional tools. Stell can transform long and highly-technical specifications into a collaborative and trackable workflow. Stell helps teams across industries avoid missing requirements and reduce risk, all while ensuring on-time delivery to customers. Engineering tools built for the next generation should not only be powerful, but also collaborative and user-friendly – a principle Stell was founded upon.

Document-to-Matrix Workflow

Toggle quickly between original documents and a dynamic compliance matrix with Stell’s dual-view system. You will never miss a clause with Stell because our platform highlights every requirement and links standards automatically and quickly. Stell’s powerful text search tool enables rapid identification of key phrases across specifications, standards libraries, manuals, and other statements of work effortlessly.

PDF Import Revolution

Stell enables instant conversion of sizable technical contracts into interactive and beautiful compliance matrices. No other requirements management tool on the market can automatically import and digitize PDF specifications. Stell saves engineers hours of manual work and enables cross-team collaboration from day one.

US-Based & Secure

Stell implements a defense-in-depth approach meeting stringent government security requirements including SOC 2 Type 2 certification and NIST 800-171 compliance. Our platform  supports the handling, storage, and transmission of Controlled Unclassified Information (CUI) in accordance with DoD and NIST standards, with a FedRAMP High ATO in progress under U.S. Space Force sponsorship.

Accelerate Operational Efficiency

Stell effortlessly automates the process of cross-team and cross-platform collaboration, so no more cutting and pasting between Word and Excel. Stell makes it easy to find anything you need, on demand.

Ensure Audit Readiness

Stell’s highly-traceable platform and matrices help you demonstrate compliance during customer audits and reviews. Nothing can fall through the cracks with built-in parent-child linking and verification evidence tracking.

The Modern Solution to Outdated Engineering Workflow

Stell features a clean, intuitive, and user-friendly platform that substitutes siloed tools, outdated software, and manual workarounds. Built for team-wide adoption, Stell is intuitively built to assist with revision control, traceability, and secure collaboration.

Stell can replace complex and siloed requirements management tools. Stell’s simple and delightful UI/UX will have your team collaborating on requirements instead of sending documents to one super-user engineer. Stell can also replace workarounds like Excel and Word to add collaboration, revision control, change control, and complex linking.
