The Myers-Briggs Type Indicator (“MBTI”) describes the Entrepreneurial personality as: Extraverted Intuition with Introverted Thinking, i.e. ENTP, or aptly labeled as “Opportunists, Innovators, Entrepreneurs”

People with ENTP preferences constantly scan environment for opportunities and possibilities. They see patterns and connections not obvious to others and at times seem able to see into the future. They are adept at generating conceptual possibilities and analyzing them strategically. They are good at understanding how systems work and are enterprising and resourceful in maneuvering within them to achieve their ends.

As enthusiastic innovators, their world is full of possibilities, interesting concepts, exciting challenges. They are stimulated by difficulties, quickly devising creative responses and plunging into activity, trusting their abilities to improvise. They use intuition primarily externally and enjoy exercising ingenuity in the world.

ENTPs are usually:
Creative, imaginative, clever
Theoretical, conceptual, curious
Analytical, logical, rational, objective
Assertive and questioning

Others may see ENTPs as spontaneous and adaptable. They find schedules and SOPs confining and work around them whenever possible. They are remarkably insightful about attitudes of others, and their enthusiasm and energy can mobilize people to support their vision. Conversational style is customarily challenging and stimulating because they love to debate ideas. They are fluent conversationalists, mentally quick, and enjoy verbal sparring. When they express their underlying “Thinking” principles, however, they may speak with an intensity and abruptness that seem to challenge others. Others see ENTPs as:

Independent, autonomous, creative
Lively, enthusiastic, energetic
Assertive and outspoken

Like all 16 MBTI personality types, there are potential areas for growth and dangers in giving less attention to the non-preferred parts of their personality preferences.
