What The Enneagram Institute does
The Enneagram Institute (legal entity: Enneagram Personality Types, Inc.) is a privately held, for-profit psychometric and education company founded in 1997 by Don Richard Riso and Russ Hudson and headquartered in Stone Ridge, New York. The company develops, validates, and distributes two proprietary online personality assessments — the Riso-Hudson Enneagram Type Indicator (RHETI v2.5), a 144-pair forced-choice test producing full nine-type profiles, and the Instinctual Variant Questionnaire (IVQ v2.0), a 37-set forced-choice test that determines an individual's ordering of Self-Preservation, Social, and Sexual instincts — alongside its proprietary Levels of Development framework. Both assessments are delivered through a dedicated Testing Center (tests.enneagraminstitute.com) and produce PDF reports including expanded type descriptions of over 2,500 words for top-three scores.
The company monetizes primarily through one-time test-code purchases ($20 per test, with volume discounts of 10–50% scaling from 2 to 100+ codes, and a $36 bundle for both tests), a network of Riso-Hudson Certified and Authorized Teachers who deliver four types of workshops (The Wisdom of the Enneagram, The Enneagram and Relationships, The Three Instincts, and The Journey of Growth) priced at $250–$295 in-person and via Zoom, and Amazon affiliate revenue on Riso-Hudson authored books. Distribution runs through a consumer-facing main website, a self-serve testing platform, business accounts for group administration, and the authorized-teacher channel. Payment processing is handled via Stripe.
The Enneagram Institute serves a horizontally diversified customer base: individual self-discovery seekers (primary segment), professional coaches and consultants, corporate HR and leadership development teams, universities, and religious/spiritual organizations. Operating with a 1-10 employee core team, the company relies on its content library, brand authority from its founders' scholarship, registered trademarks (RHETI, EnneaThought, The Enneagram Institute), and the EnneaThought daily email newsletter to drive organic demand. Co-founder Don Richard Riso is deceased; Russ Hudson serves as President Emeritus and Annette Peter as President and General Counsel.
