About us

Supporting businesses to drive impactful change

We’re an independent, women-led and owned sustainability consultancy based in the heart of Bristol. We support businesses globally to drive impactful change through the effective use of their sustainability data. Our vision is to make sustainability accessible for all.

Sustainit was founded in 2006 by Charlie Stockford. Over the last 18 years, we have grown into a globally renowned sustainability data consultancy, going from strength to strength even during tough times.

In 2021, Charlie passed the leadership to her daughter Pip, marking the beginning of our journey as a proud second-generation family business. 2023 was a milestone year with record-breaking growth, and as we look to the future, we remain committed to delivering high-quality and integral services to our clients.

Bridging the gap

While working for a large corporate, our founder Charlie noticed that it was fast becoming a requirement for companies to implement CSR strategies and report on their non-financial data. There was a disconnect between the in-house teams doing the reporting and the software they needed to use. Huntstock (as the business was originally known) was born with the aim of bridging the gap between clients and their data management systems.

A new name

As the business grew, and Charlie took on more clients, she found she needed more in house technical support, so David (her husband) joined the team. The company also rebranded as ‘SustainIt Solutions’.

Surviving the recession

A tricky time for many businesses, we ducked, dived but ultimately survived the banking crisis and global recession. A hung parliament in 2010 and its effect on business effectively froze the growth of the business but once again, we weathered the storm.

The team grows

Fresh from university, Katie (Charlie and David’s daughter) became the third Stockford to join our family business. With a degree in Statistics under her belt, she joined the Client Support Team delivering day to day work for clients. She’s still with us today, and is now the longest serving member of the team.

Welcoming Pip

Another landmark year of growth and the addition of another Stockford (C&D’s other daughter), Pip. Having come from a commercial background, Pip joined the team to continue pushing forward the marketing and sales function of the business.

Our new CEO

We waved goodbye to David, who sailed into retirement and a year later our CEO and founder Charlie joined him! In 2021, Pip took over the business and despite the pandemic putting a temporary halt on growth, we were able to adapt to changes in the market, pivoting to encompass strategic services alongside data consulting.

A new look

After a target-smashing year, with a bigger team in place, we’ve rebranded to Sustainit with a new look and feel.
