people we work with

We take great pride in building close, trusted relationships with our clients - investing time to truly understand their businesses, ambitions, and challenges.

“Having worked with both Blanche and Mark in media-related roles over a number of years, I am delighted to see them formalising their business as Sainsbury&Sainsbury Ltd.
Their understanding of marketing, promotion, communications, and PR is exceptional. They combine strategic insight with practical delivery, and their network of contacts and professional recommendations is among the strongest I have encountered. They bring tremendous energy to every business they work with, generating innovative ideas, driving revenue growth, and helping to build high-performing teams.
Working with Blanche as Chair of Bluestone was both rewarding and enjoyable. Her vision, clarity of thought, and ability to inspire those around her helped us achieve a great deal during her tenure. My team thoroughly enjoyed working with her and benefited significantly from her guidance and support.
I would have no hesitation in recommending Sainsbury&Sainsbury Ltd to any organisation seeking greater clarity of direction, fresh commercial thinking, and new opportunities for growth.

Above all, Blanche and Mark are good people who genuinely care about the businesses and individuals they work with.”

“Having Blanche onboard as NED of WeLaunch has been the single best decision I have made as a founder, a genuine gamechanger.

Blanche's leadership credentials speak for themselves, but her network has fundamentally changed what is possible for WeLaunch. I am now in rooms and in conversations with investors that would have been completely out of reach without her. That alone is transformational.

Blanche brings a rare ability to cut through complexity and give founders exactly what they need most: absolute clarity on their purpose, their proposition, and their path forward. She operates at a level that far exceeds the conventional NED role, she is a strategic force who backs the people she works with. As a sole founder, the weight of building something significant can be challenging. Blanche removes doubt and instils conviction. The belief Blanche has invested in me and in WeLaunch has directly shaped the ambition and momentum of this business.

Sainsbury&Sainsbury Ltd don't just support the businesses they work with, they transform them.The impact is real, it is immediate, and it is the kind that changes your trajectory permanently. ”

Katie Fernquest, WeLaunch CEO

“Working with Blanche and Mark has helped me grow and shape my business internationally. We’ve now expanded into countries we had never previously operated in.

Their black book of contacts is incredibly strong and on a completely different level in terms of the professionals they know and work with.

Mark’s attention to detail around logistics, procurement, and pricing models has been invaluable. His strategic thinking around expanding the business, while also encouraging me to consider other investment opportunities was especially helpful.

They are both trusted professionals and genuinely good people, and my team and I truly value having them around.”

“When I was seeking a group Chair to helm our next ULTRA CEO and MD peer group, I asked Members if they knew a suitable leader in Wales, who had the background, reputation and profile to support 12 Members once a month on their business journey. One of our Members said ‘you need to speak to Blanche Sainsbury – she’s a rockstar!’. Another Member introduced us before I had even made the request. Both couldn’t have been more right.

In the room, she just makes things work. By running these special, confidential spaces with compassion – she has made a significant and positive impact on her group Members, no doubt their businesses, and most certainly ULTRA as a whole. To lead leaders requires something very special, and ‘X factor’ if you like - and Blanche Sainsbury has this in abundance.”
