SISU CONSULTANCY

Passionate about unlocking the potential of your people

At SISU Consultancy, we support small to medium enterprises striving for growth with bespoke strategic HR solutions that align with your business goals.

Bespoke HR strategies tailored to your needs

We know that no two organisations are the same, so a cookie-cutter approach to HR won’t always work.

Your people deserve more than an edited template downloaded from the internet or a one-size-fits-all solution that is completely out of context for your business.

Allow us to be your HR partner and guide you through all things people-related, from recruitment to performance management, refining policies and bringing out the best in your business.

Leading with care and intention

With over 20 years of experience in the HR industry, our founder and CEO, Gillian French, understands the intricacies of cultivating a people-centred culture that encourages growth and success in the workplace.

Leading with care and intention, Gillian believes in adding humanity back to the workplace.

Alongside a team of passionate professionals, SISU Consultancy was created with the idea that HR isn’t just a “nice to have” but a necessity for organisational success..

What it’s like to work with us

  • Fresco

    “Gillian is a powerhouse and an absolute pleasure to work with. She has empowered the Fresco leadership team with the tools and processes to foster open, transparent and constructive collaboration, enhancing our effectiveness both as individuals and as a collective. Part of this toolbox is a remarkable ability to lead impactful offsites, which have strengthened our strategy whilst accelerating the transformation into a more cohesive and effective team. Her support has also been invaluable in the hiring process, where her insights and guidance have significantly contributed to building a world class high performing team. I highly recommend Gillian.”

    Ben Harris - CEO Fresco

  • BRUNSWICK GROUP

    “Working with Gillian was transformational for me both personally and professionally. Gillian’s kindness, thoughtfulness and patience during our sessions meant that I felt incredibly safe which made it possible for me to explore difficult topics and emotions. Since working with Gillian, I have a renewed attitude and approach to my work and career and many areas of my personal life too.”

    Sarah Purbick - Brunswick Group Partner, Head of Operations, Continental Europe


  • Cityswift

    “Gillian has been an invaluable asset to our team, especially during our executive hiring process as we scale. She excels at identifying gaps, coaching teams, and ensuring we attract top-tier talent aligned with our vision. Her strategic insights and ability to streamline complex processes have elevated our recruitment efforts. Gillian’s contributions go beyond filling roles; she helps shape our leadership team for sustainable growth. We are fortunate to have her expertise driving our success.”

    Brian O’Rourke - Cityswift

  • Travel Chapter

    “I will always be so grateful for the coaching programme I did with Gillian. In fact, I thank her often still, whenever I realise I’m using something she taught me and feeling stronger because of it. Her understanding of people and behaviour really helped me, not only in developing my own leadership style, but how to understand and work better with those around me.”


    None of us should ever stop learning more about ourselves and how to be better, and I couldn’t recommend Gillian more highly for that!

    Jayne M CEO - Travel Chapter

  • FINE GRAIN PROPERTY

    Following a period of significant growth, 2023-2024 was an important time for Fine Grain Property, as we sought to put in place structures to position the business for a scale. At the heart of these measures was our desire to establish a happy healthy high-performance team.

    Gillian and her team were retained to implement a performance enhancement program in the business. This included the selection of software, the development of a performance enhancement manual, initial training, and ongoing coaching of team members.

    They have had, and continue to have a significant impact on the business and I have no hesitation in recommending them.

    Colin MacDonald - CEO Fine Grain Property

  • FRESCO

    “Gillian supported our leadership team on a 3 day offsite, where her mix of leadership expertise, candour, strategic insight and deep understanding of psychological safety ensured the offsite was both effective and successful. Gillian’s authenticity, energy, and awareness of group and interpersonal dynamics laid the foundation for much improved alignment, planning and communication across our leadership team.”
