Imagine having a leadership mentor who draws on some of the greatest thinkers of all time — and is available the moment you need it. That's Principle Companion. Principle Companion is built on the principles of human progress — ideas proven across centuries to help individuals, organizations, and societies flourish. In a world of constant change, these principles remain constant. They've guided Koch Inc. through sixty years of transformation — and now Charles and Chase Koch share them in their new book Becoming a Principle-Driven Leader: 41 Principles to Build an Enduring Business. This app complements the book by eliminating the distance between knowing principles and applying them to real situations. SOLVE A people challenge. A tough decision. A strategy question. Bring your problem the same way you would with a mentor — in your own words, even out loud — and leave with the right next step and the reason it's the right one. PRACTICE Close the gap between who you are today and who you can become. Over time, Principle Companion learns where you've been and where you're growing — so every conversation builds on the last. PRINCIPLES The 41 principles are drawn from thinkers like Hayek, Maslow, Sowell, and Frankl — ideas that shaped how we understand human flourishing. Explore each one and see how it relates to others. Any one of them can be applied to a challenge you're working through right now. New to principled thinking? It meets you there. Already deep in your practice? It challenges you further. The more you return, the sharper it gets. Principle Companion is free. No subscriptions. No ads. Just a leadership mentor for anyone ready to be all that they can be.

The EHS Compliance Hub is a set of plain-English environmental, health & safety compliance tools — made for the people who actually file the report. We track the rules and deadlines so you don't have to dig through the Federal Register and the CFR yourself. Everything is explained in plain English, with the source one click away. WHAT'S INSIDE • Rule-change feed — new and proposed EPA, OSHA, and DOT rules from the Federal Register, summarized in plain English and tuned to your facility. • Reporting-deadline calendar — the recurring environmental reports that matter (TRI, Tier II, GHG, and more), so nothing sneaks up on you. • Requirements packets — pick a rule and get a clean, cited summary of what it actually requires, built from the current eCFR text. • eCFR rule lookup — search and read the live text of any CFR section. • EPA enforcement lookup — check a facility's enforcement and compliance history. • Applicability determinations (ADI) — search EPA's applicability determination index with plain-English summaries. • Consent decrees & settlements — a feed of EPA/DOJ enforcement actions, in plain English, so you can see where enforcement is heading. • AIM Bot — ask any regulatory question and get a straight, cited answer. • Community Q&A — ask and answer questions alongside other practitioners and verified subject-matter experts. WHO IT'S FOR EHS managers, compliance specialists, consultants, and anyone responsible for environmental reporting and staying on top of changing regulations. FREE DURING THE OPEN BETA The Hub is free to use during our open beta. A work or school email is required to join — it keeps the community professional and confirms you're a real practitioner. Built by AIM Environmental Health & Safety (aim-env.com). Not legal advice. The Hub helps you find and understand requirements; always verify against the official source before you rely on it.
