Sullivan & Stanley helped me transform my company from one of the most traditional bureaucratic organisations, into a product-centred faster delivery FinTech organisation.

SVP Engineering, Financial Services

“

I cannot recommend them highly enough. Sullivan and Stanley represent the new world of consultancy.

Technology Director, Energy Sector

“

Sullivan & Stanley's alternative consulting approach has delivered value-based outcomes over short periods of time with an agreed exit strategy that has helped build and deliver sustainable internal capability.

Director of IT, Telco

“

Having S&S on board to push us through has been critical to the success and enabled us to move to the next phase. You have set frameworks, ways of working and discipline that the whole leadership team and organisation can now use for other projects.

Senior Director of Strategic Initiatives, Retail

“

It is always a risk working with new people when there is so much change going on. However, the risk has paid off. It's like we have worked together for so long - I know I can rely on you and feel immediate trust.

Head of Change, Housing Sector

“

Working together with the S&S team together with ours, we were able to deliver the work in record time, which is incredible. And I know from experience from looking at the markets, that it normally takes much longer to do that.

International Retail Client

“

S&S led us through the change process, trained us, been there so that we avoided the steps back, which would have been very easy to do. It's definitely has been a good relationship with S&S.

CEO, Energy Sector

They focus on the broader change perspective. You're not engaging a typical consultancy that's just coming in to do the job. They may come in and do some work with you but what they also do is engage with you as an organisation.

Commercial Director, Financial Services

“

Delivering this change was like changing all of the major components of a plane, whilst flying it and with CV19 - flying in fog. I would absolutely recommend S&S as partners to deliver change - the methods and the network.

Chief Technology Officer, Retail
