Title

CECILE DE LASTEYRIE

Executive Coach & Consultant

Summary

Cécile’s conviction is that transformation only lasts when strategy, culture and customer focus move forward together — forged over more than 25 years leading change from within international B2B organisations, including Société Générale, PwC & EY, not just advising on it. She has managed teams of over 300 people internationally and sat on executive committees for 15 years. Today, she partners with CEOs and leadership teams to navigate transformation and build the leadership capabilities needed to sustain it.

Coaching Style

What sets Cécile apart is her “Client Rubik’s Cube”: having held top management positions in sales, marketing & communications, she reads the whole commercial chain — strategy, brand, client relationship, performance — and helps leaders align it.
Clients describe her above all as a true pillar to lean on: reassuring and deeply grounded, she passes on that same anchoring to help them find their own. She secures and she challenges — always with kindness — saying what needs to be said, however uncomfortable, with warmth and humour, so people can reveal the best version of themselves.

Professional Experience

Throughout her career, Cécile has helped organisations accelerate growth, strengthen client relationships and build high-performing teams — as Sales Director, then Marketing & Communications Director, then Deputy General Manager, in financial and professional services.

Qualifications

She holds an Assas Masters in corporate & tax law, ICI Master Coach, a Aliath certified board member and an MBTI level 1&2 and DiSC certification.

Personal Interests

Cécile is the chair of an amateur theatre company and is a compulsive reader.
