Under this partnership, our Founder & CEO, Shinsuke Kiyono, has officially joined Cinter Career as a Partner Coach, contributing to their career coaching services.
We apologize for the delay in this public announcement, which was due to the ongoing development of our corporate website.
Background and Purpose of the Partnership
Cinter Career specializes in professional staffing, particularly in the IT sector—including PMOs, engineers, and other technical roles. The company actively supports professionals in the U.S., Canada, and Japan (starting this year) in their job search and career transitions, with a strong track record in technology talent placement.
Cornerstone Strategy supports Japanese corporations and professionals in building global careers through leadership development, career strategy, and HR transformation. This partnership enables both organizations to offer not only short-term job placement support, but also long-term, strategic career development services.
In today’s rapidly evolving job market—particularly within the tech industry—it is increasingly important to make career decisions aligned with one’s personal values and long-term goals. Through this collaboration, both companies will work together to support job seekers in making well-informed, fulfilling career choices.
For Those Pursuing Global Careers
True career development requires more than evaluating immediate job titles or compensation. It involves defining a clear vision for the next 5 to 10 years, and making consistent, intentional choices toward that future.
With Cornerstone Strategy’s coaching services for professionals and Cinter Career’s talent placement and matching expertise, we are committed to helping individuals take ownership of their careers and build fulfilling, authentic paths in the global market.
