Our mission

When we set out to help businesses become more change capable, we quickly realized that internal change management offices (CMOs) were at the forefront of this mission. We’ve taken a lot of notes from working with the world’s most influential companies and found that these internal practices face many of the same challenges. That’s why we’ve made it our mission to support them.

We believe that adaptive organizations of the future are enabled by high impact change management offices now.


Our story

Founded in 2016, Issoria merges two worlds to answer customers’ demands for a new model of change management consultancy.  A hybrid of change management consulting and change management staffing expertise, our founding team brought together 20 years’ experience in both disciplines to launch our innovative professional services firm.

Having begun with 2000+ consultant members, Issoria has grown to 5000+ members on a referral only membership basis. Issoria now operates as a closed network of elite consultants with a truly global footprint. 

Following a multi-award winning year in 2018, the business continues to grow at a rate of 100%+ year on year. Issoria’s growth funding partner – ABN AMRO Commercial Finance, who have over $2.2bn worth of funds in use across their client base, have committed to providing ongoing funding to cover business growth across 80 countries around the world.

Conscious Capitalism

We believe that business is good when it creates value for all stakeholders. For Issoria this means our people, our customers, our members and our communities.

Conscious Capitalism is a way of thinking about capitalism and business that better reflects where we are in the human journey and the innate potential of business to make a positive impact on the world.


Fighting for the community

We are proud to support Carney’s Community, a charity that gets disadvantaged and excluded young people off the street and away from a life of crime by giving them skills, discipline and self respect.

One of the charity's projects is to help young people, through Business Counselling and Mentoring, to start their own business. Our employees mentor Carney’s participants, and Issoria is committed to donating 1% of all net profits to the charity on a long-term basis.
