100x Impact at LSE: GBP 150,000 and a 16-week accelerator for social ventures with proven models

100x Impact, an accelerator initiative based at the London School of Economics (LSE), has opened applications for its 2027/28 cohort. The programme aims to identify and back ambitious social ventures capable of scaling their solutions to match the scale of major societal challenges.

Selected organisations will receive GBP 150,000 in catalytic grant funding and entry into a dedicated 16-week accelerator. The application window is open until 2 November 2026, with the core programme scheduled to begin in September 2027.

What is funded

The programme provides GBP 150,000 in catalytic grant funding to each selected venture. This non-dilutive financial backing is intended to help organisations establish and execute viable pathways toward large-scale delivery.

In addition to funding, participants join a 16-week accelerator focusing on scaling strategy, impact measurement, and leadership development. The programme provides access to LSE research expertise and initiates a long-term partnership with a global community of funders, advisers, and peer organisations.

Who can apply

The call is open to both for-profit and non-profit social ventures, including start-ups, small and medium enterprises (SMEs), and non-governmental organisations (NGOs). Applicants can apply from any country worldwide.

Eligible organisations must have a proven model and operate within one of the primary impact domains: health, education, climate, financial inclusion, or democracy. The donor seeks leaders with the ambition and operational basis to grow their impact across systemic barriers.

Conditions and requirements

Applicants must present clear evidence that their core model already works in practice, as the programme is designed for scaling rather than early-stage concept testing. The accelerator expects leadership teams to show openness to rethinking growth models, systemic endgames, and partnership strategies.

Practical tip. Focus your submission on systemic leverage points rather than linear customer growth, explicitly articulating what evidence base and institutional partnerships will convince broader systems to adopt your proven solution.

How to apply

Candidates must complete and submit their proposals through the donor’s application platform before the deadline on 2 November 2026. The selection process assesses the maturity of the model, systemic scale potential, and alignment with the accelerator’s impact areas.

Successful teams will join the cohort for the autumn programme, which starts in September 2027. Applicants are advised to review the official guidance regarding eligibility and programme expectations prior to submitting materials.
