GoodGoblin.ai is the ultimate "Admissions Operating System" designed to democratize elite college guidance. We believe expert mentorship shouldn't be a luxury for the few, so we built a data-driven platform that levels the playing field for every student. Our Four Pillars of Success Our platform guides students through the entire journey—from freshman strategy to senior year submission:   Architect (Grades 9–11): Builds a multi-year roadmap and identifies "profile gaps" early on.   Strategist (Grades 10–12): Uses data to find the perfect mix of "Reach," "Target," and "Safety" schools.   Editor (Grades 11–12): Provides 24/7 AI narrative coaching with instant feedback on clarity, story, and structure.   Analyst (Grade 12): Performs a final holistic audit to calculate real-time acceptance probabilities before you hit submit. Why It Matters Proven Results: Our users see a 31% boost in admission odds, with 97% of students securing a spot at a Top-30 university.   Radical Transparency: We show students exactly why an essay works using the same metrics admissions officers use.   Engineering Precision: We turn "guessing" into "optimizing" by analyzing millions of data points from successful applicants.   Join us in our mission to make the path to a dream university predictable, affordable, and stress-free for over 50,000 students worldwide.

HEAL (Healmenow Inc.) is building the first screenless, voice-first companion for medication adherence and mental wellness. Instead of another app competing for screen time, HEAL lives as a physical device in your space — you talk to it, it responds, it helps you stay on track with your care. We sit at the intersection of hardware, AI, and emotional design, because behavior change doesn't come from reminders and gamification — it comes from feeling understood. What We're Building A screenless medication adherence device paired with an AI voice companion. Say "Hey HEAL" and it dispenses your medication, logs adherence, and has a real conversation with you about how you're doing — building the kind of clinical documentation that qualifies for Medicare Remote Therapeutic Monitoring (RTM) reimbursement. V1 is built and working; we're now developing V2 using real user data, targeting a significant jump in treatment effectiveness. Our voice companion also carries a crisis-escalation layer, built with clinical oversight from a psychiatry advisor with 15+ years of experience. Hard Problems We're Solving Medication non-adherence, especially for mental health conditions, is a massive and under-addressed problem — people don't stop taking their medication because they forget, they stop because no one is checking in on how they actually feel. Existing solutions (pillboxes, reminder apps) treat this as a logistics problem, not an emotional one. We're solving three hard problems at once: designing a voice AI that can hold a caring, clinically-sound conversation without a screen; building the crisis-detection logic responsible enough to flag real risk without false alarms (the single highest-risk, highest-scrutiny part of the FDA classification question); and proving this new adherence data can actually satisfy Medicare RTM reimbursement requirements, which is what will make this sustainable at scale rather than another wellness gadget.
