Our story

Sionic unites three firms – Catalyst, Knadel and Sionic Advisors – with a common commitment to deliver outstanding expertise to financial services clients worldwide. 

Our different histories do not divide us: they are part of who we are now. Together, our global track record of achievement enables us to advise clients with informed understanding, as well as technical expertise.

Wherever we work, we share common values and an enduring commitment to expertise and to people: our colleagues and our clients alike. 

These are some of the key moments in our story, so far.
