Unreasonable Mentors
Celinne Da Costa
Private Advisor & Mentor at Story Atlas®
Celinne is an Unreasonable Mentor. Celinne was part of Unreasonable Impact Americas 2026, and has advised over 16 Unreasonable companies.
Celinne Da Costa is a trusted advisor, speaker and bestselling author who works with accomplished leaders navigating some of the most consequential moments in their lives and work.
She is known for her surgical precision in seeing beneath the presenting problem to the story shaping a person’s choices, and the truth they haven’t been able to reach alone... so they can stop holding back, reach as far as they know they can, and leave a lasting mark on the people and rooms that matter most.
For more than a decade, Celinne has worked with visionary founders, influential creators and senior leaders in more than 60 countries, as long-term counsel through multiple chapters of their lives and work.
Her proprietary method, Story Atlas®, blends brain-change techniques with ancient healing modalities, and she carries a rare gift for tracking and moving stagnant energy.
Through this work, clients have published bestselling books, left celebrated careers on their own terms, rebuilt meaningful careers, created multi-million-dollar businesses, fallen in love, grown their families, and made many other seemingly impossible yet long-held visions a reality.
Celinne has spoken at TEDx and been featured in Forbes, Entrepreneur and Business Insider.
Private mentorship remains at the centre of Celinne’s practice. The measure of the work is the life that follows: whether what a client knows to be true becomes visible in how they actually live.
