I took both tests (links at bottom of the post) and was pleasantly surprised both produced the same personality type for me: ENTJ. Now I have some soul-searching to do, but you can rest assure that either test (one free, one costs $60) will provide an accurate assessment of your personality type.
What you do with the information is up to you!
The Myers-Briggs Type Indicator (MBTI) is one of the most widely used personality frameworks in business. Based on Carl Jung’s theory of psychological types and developed by Isabel Briggs Myers and her mother Katharine Cook Briggs. The duo created the MBTI in the 1940s with the aim to help people understand how they perceive the world and make decisions. For entrepreneurs especially, self-awareness can be a critical competitive advantage.
How It Works
The MBTI sorts people across four dimensions, each representing a spectrum between two preferences. Combining one letter from each gives you one of 16 personality types, for example ENTJ, ISFP, or INTJ.
Type | Nickname | Core Traits | Entrepreneurial Tendency | Example Job/Role That Fits Perfectly |
INTJ | The Architect | Strategic, independent, high standards | Strong in technical or systems-driven ventures | Chief Strategy Officer or Tech Startup Founder (visionary planning & execution) |
INTP | The Thinker | Analytical, inventive, theory-oriented | Well suited to research, tech, or product-focused businesses | Research Scientist or Software Architect (deep innovation & problem-solving) |
ENTJ | The Commander | Decisive, driven, natural leader | Built for scaling and leading teams | CEO of a Scaling Company (commanding growth & teams) |
ENTP | The Debater | Creative, quick-thinking, loves disruption | Strong at pitching and pivoting, weaker at execution | Venture Capitalist or Innovation Consultant (idea generation & deal-making) |
INFJ | The Advocate | Principled, empathetic, long-term focus | Thrives in mission-driven or coaching businesses | Nonprofit Executive Director or Executive Coach (visionary impact & guidance) |
INFP | The Mediator | Idealistic, values-led, creative | Strong in creative or purpose-driven ventures | Author/Novelist or Indie Game Developer (authentic creative expression) |
ENFJ | The Protagonist | Charismatic, people-focused, inspiring | Natural at building teams and leading with vision | Motivational Speaker or HR/Team Development Director (inspiring & uniting people) |
ENFP | The Campaigner | Enthusiastic, imaginative, connector | Great at marketing, community, and early-stage energy | Marketing Director or Startup Community Builder (energizing ideas & networks) |
ISTJ | The Logistician | Reliable, detail-oriented, process-driven | Strong in operations, finance, and compliance-heavy industries | Operations Manager or Financial Auditor (ensuring flawless systems & reliability) |
ISFJ | The Defender | Loyal, caring, practical | Thrives in service businesses and client-facing roles | Nurse or Client Services Manager (dedicated support & care) |
ESTJ | The Executive | Organized, direct, systems builder | Excellent at running established operations | Corporate Executive or Franchise Owner (efficient management & structure) |
ESFJ | The Consul | Warm, organized, relationship-focused | Well suited to hospitality, retail, and community businesses | Event Planner or Hospitality Manager (hosting & nurturing relationships) |
ISTP | The Virtuoso | Hands-on, analytical, independent | Strong in trades, engineering, or technical services | Mechanical Engineer or Forensic Technician (practical problem-solving & mastery) |
ISFP | The Adventurer | Flexible, artistic, values-driven | Thrives in creative, design, or lifestyle businesses | Graphic Designer or Independent Artist (expressive & aesthetic creation) |
ESTP | The Entrepreneur | Bold, action-oriented, opportunistic | Natural salesperson and deal-maker, strong in fast-moving markets | Sales Director or Real Estate Developer (thriving in high-stakes deals & action) |
ESFP | The Entertainer | Energetic, spontaneous, people-loving | Excels in events | Event Host/Entertainer or Experiential Marketer (bringing fun & energy to crowds) |
Why It Matters for Entrepreneurs
Starting and running a business demands wearing many hats: visionary, manager, salesperson, negotiator. Your MBTI type can illuminate where you naturally excel and where you may need support, partners, or conscious effort.
Extraverts tend to thrive at pitching, cold outreach, and relationship-building, while Introverts often excel at deep one-on-one relationships and focused problem-solving. On the information side, Intuitive types are natural visionaries great at spotting opportunities, while Sensing types excel at operational detail and reliable delivery. Thinkers make tough financial and strategic calls quickly, while Feelers build loyal teams and earn customer trust through empathy. And when it comes to structure, Judgers bring strong planning and systems, while Perceivers adapt quickly in fast-moving environments.
Practical Uses for Small Business Owners
When hiring and building a team, pairing complementary types, such as a visionary N with a detail-oriented S, can cover blind spots on both sides. In client communication, knowing whether someone leans Thinking or Feeling helps you tailor your pitch: Thinkers respond to data and ROI, Feelers respond to story and relationship. For managing stress, it helps to know your own pattern: ENTJs can become controlling under pressure, INFPs may withdraw. And for solo founders, if you are a strong N-type visionary who struggles with operations, that is a signal to hire an operations manager early or invest in systems that compensate.
Important Caveats
The MBTI has real limitations. The scientific consensus is that it has low test-retest reliability, with a significant proportion of people getting a different result when retested weeks later. It also treats personality as binary, which does not reflect the reality that most people sit somewhere on a spectrum. Think of it as a useful starting conversation, not a definitive diagnosis. For more rigorous personality data, many organizational psychologists prefer the Big Five (OCEAN) model, which has stronger scientific backing and is often used in leadership development contexts.
