TSIC

What TSIC does

TSIC (The Social Investment Consultancy) is a London-headquartered, values-led advisory consultancy that helps foundations, corporates, charities, social enterprises, and impact investors measure, manage, and verify social and environmental impact. The firm operates ten core service lines spanning social impact measurement, corporate social impact, DEI advisory, Sustainable Development Goals alignment, revenue generation, research and convening, innovation, impact investing and ESG, organisational development, and strategic planning. Its underlying technology layer consists of proprietary evaluation frameworks — including the DEI Cube Maturity Model, OCEAN Racial Justice Principles, TREE Tool, USERS Framework, and IMPACT Verification Framework — packaged as both internal methodologies and publicly downloadable thought-leadership assets, supplemented by a technology partnership with SoPact for SDG measurement.

The firm generates revenue through project-based professional services engagements delivered directly to clients, priced on a quote basis tailored to scope, and sourced through a combination of direct sales, professional referrals, conference presence, and community convening. TSIC positions itself as a knowledge intermediary and "movement infrastructure partner," leading or co-founding sector networks such as the Diversity Forum (50+ firms), Women in Social Finance (120+ members), and the Equitable Evaluation Collective. In 2023-2024 the firm expanded structurally through the acquisition of TSIP (founded 2008) and Renaisi (established 1998) to form an Impact Collective, and in 2026 announced a strategic partnership with Rimm Sustainability to scale global sustainability and impact infrastructure. The company is a UK B Corporation since 2015, is wholly owned by Managing Director Bonnie Chiu, and operates with a globally distributed team across Europe, Asia, Africa, Oceania, and the Middle East, with regional offices in London, Hong Kong, Ghana, and India.
