What We Do

TSIC works with ambitious organisations and changemakers. Those that want to break silos, embrace the unknown and are keen to create systemic change in their markets. We work in a collaborative and dynamic way, helping our clients to think differently, and perform to their greatest potential. In order to create the deepest social investment, we enable our clients to hear the voices and consider the opinions of those that can shape the impact and investment that they make.

Our business is focused on 4 pillars:

Words from our clients…

The work TSIC did was invaluable. It gave Mada an independent profitability analysis as well as areas of focus. It provided the foundation upon which an informed decision could be made. Our experience with TSIC was very positive as I believe the work TSIC undertook was of high-quality and met Mada’s expectations. I will certainly recommend TSIC to others.

There are few organisations that have such a deep understanding of social impact measurement. Through our Good Kitchen programme, Bonnie and her team engagingly and meticulously guided five social businesses through how to measure the difference they were making and why it was important. With a heap of relevant case studies, well-prepared workshops and follow-on activities, it’s fair to say that it fundamentally changed how we thought about and conducted social impact measurement.

Through taking part in The Charities Intrapreneurship Programme, we have gained confidence around generating and putting forward ideas, an understanding of the wider market place, and an understanding of how to go about feasibility studies and client research. We also gained lots of great feedback and ideas.

Research and convening

Our vision is a thriving social sector where funds are directed where they can make the biggest impact for those who need help the most. 

To achieve this, we conduct in-house research on issues important to the sector. We deliver through first-hand experiences, professional and academic expertise. Some examples of reports we produced include:

  • The City of London Corporation to scope potential new sources of capital for the UK social investment market. Read more here.
  • Minority Supplier Development UK to identify ways to promote inclusive procurement, launched in House of Lords in October 2014 and received nationwide coverage. Read more here.
  • SPRING Accelerator to produce a comprehensive report on investing with a focus on girls and young women in emerging markets, and on specific needs, challenges and opportunities in five sectors. Read more here.

We are actively working to improve diversity and inclusion among impact investors. As a firm that very much prides ourselves on embracing diversity in terms of age, race, ethnicity, class, religion, gender, sexuality or disability, we work to ensure that these systems of discrimination are not perpetuated among capital and wealth holders. The two initiatives we are currently convening are:

  1. Diversity Forum
    Diversity Forum gathers over 50 social investment firms and 100 individuals across the social investment sector in the UK, to drive inclusive social investment – through the convening of Diversity Working Group, Diversity Champions, commissioning of research and knowledge sharing.
  2. Women in Social Finance
    A network of 120 senior female professionals working in social finance, dedicated to increasing visibility of female leadership, providing peer support and training for career advancement, and influencing the agenda on gender lens investing.


We are dedicated to creating systems change through working with our clients and engaging in sector initiatives, but we also incubate our own projects. We are currently incubating two projects:

They are working to build technology products to model complex humanitarian engagement in conflict zones, and simplify the process of collecting large-scale community feedback. TSIC is incubating the project through: building its business plan and fundraising, engaging with humanitarian stakeholders including local responders, funders and international agencies, and building the methodology and data model. Humanity Data launched in April 2019 and is funded by Humanitarian Grand Challenge.
