MESSAGE FROM THE CEO

Working backwards from the future
to expand the potential of business and people.

Message from the CEO

Our philosophy is to pursue the wellbeing of every organisation we work with while enabling each individual to grow. As AI and digital transformation accelerate market change, we believe companies must work backwards from their future objective and reassess their past and present assets from multiple angles.

What matters to us is not appointment volume alone. We define the market and customer from the business plan, refine hypotheses through the Voice of Target, make contact ourselves, and validate the route through meetings and contracts. The result becomes a sales foundation that remains in the client organisation.

Declinaison holdings combines the perspective of founders and CxOs with the determination to execute new-business development in the field. We work alongside those creating the next generation and turn unseen revenue opportunities into repeatable businesses.

Taishi Tanaka, Representative Director, Declinaison holdings Inc.
