Our Story

Founded in sustainability, developed in fintech


We started as sustainability consultants

Trellis was founded by ESG consultants to Australia’s leading sustainability-focused organisations.


We became a SaaS provider

In a mission to help our customers track their environmental data, we provided them with  web access to our internal database (formerly known as C3online).


We introduced Trellis

With a growing pressure on organisations to understand the connection between environmental and financial impact, as well as the need to accurately report on it – we developed the capability to produce financial grade emissions data.

In 2016 we released an improved technology that uses transactional data of any organisation, applies Machine Learning and enables data driven decision-making from a ‘single source of truth’.


Beyond environmental sustainability

Trellis now supports and enables collaboration between multiple business functions, including Finance, Procurement, and Facility and Asset Management. Its insights have been helping over 50 organisations, including an ASX listed entity, to achieve their environmental and financial sustainability goals.
