Who we are

It all began back in 2011 when Chris Bennett, Ed Gabbitas and Paul Sutcliffe started EVORA Global, a niche sustainability consultancy focused on the real estate investment market.

Back then, sustainability software was thin on the ground, but Chris, Ed and Paul all shared the passion of making a difference in real estate sustainability by using data.

That’s how SIERA was born.

Fast forward to today and there is now a dedicated in-house team of SIERA software professionals.

SIERA is used by all of EVORA’s 80+ consultants to deliver tech-enabled solutions to our clients – and it does it amazingly well. It has helped us to win some major instructions with leaders in the industry such as Schroders, LGIM, UBS, Hines and The Crown Estate.

SIERA is an incredibly powerful software tool, totally niche to the real asset investment market. It helps EVORA’s consultants to deliver amazing solutions to our clients, and it helps our clients to understand and reach their sustainability goals.

This is the essence of who we are.
