Wanted: Social Unicorns. A New Blueprint for Scaling Impact in the Third Sector
The Hunt for a New Breed of Unicorn
100x, the global impact initiative based at the London School of Economics (LSE), has officially opened applications for its 2026/27 accelerator programme, signalling a global search for a rare and powerful new breed of organisation. It is hunting for ‘social unicorns’—a concept that flips the venture capital world on its head. Instead of chasing a billion-dollar valuation, these ventures are defined by their potential to positively impact a billion lives. For a UK charity sector grappling with a challenging global climate, where countless proven solutions fail to move beyond the pilot stage, this represents more than just another funding round. It is a significant opportunity to engage with a new paradigm for achieving transformative, sustainable scale, challenging long-held assumptions about what it means for an organisation to truly grow its impact.
The search is on for bold, ambitious social ventures—both for-profit and non-profit—to join the 2026/27 cohort, with applications closing on 10 November 2025. The core offer is substantial: £150,000 in unrestricted grant funding for each selected venture, the possibility of further catalytic capital, and access to a bespoke accelerator programme that leverages the LSE’s world-class intellectual and network resources. And the ambition is just as vast. As Fan Gu, Chief Investment Officer at 100x, states, “We believe the world needs more social unicorns – ventures whose models and approaches can positively impact hundreds of millions of lives, if not of billions.”
What truly sets 100x apart, however, is a strategic philosophy that redefines the very meaning of scale. It posits that the ultimate goal is not necessarily to grow the organisation itself, but to scale the impact model. This is framed through the concept of “endgames”—strategic pathways to mass impact that might include government adoption of a proven service, commercial adaptation by other companies, or the creation of an open-source model that others can freely replicate. This shifts the focus away from the endless cycle of fundraising for organisational expansion and towards a more strategic question of how a solution can spread most effectively. For these ventures, as CEO Kieron Boyle notes, “it’s the impact that matters, not venture growth alone.”
To be a contender for this programme, ventures must already be on a significant trajectory. 100x is seeking organisations with an established proof-of-concept, evidenced by reaching at least 50,000 end-users, and which have already raised a minimum of USD 250,000 in capital. They must have a team of four or more and be able to demonstrate what the accelerator calls “Outstanding Leadership,” a “Distinctiveness of Solution,” and the sense of being on the “precipice for explosive growth.” While the search is global, the programme has an explicit goal for 70% of its portfolio to come from emerging markets and places particular value on female-led organisations.
This call for applications builds on a powerful precedent. The existing 100x portfolio of 35 ventures is already reaching a combined 100 million lives, tackling systemic issues from healthcare to climate action. Previous cohorts include staggering examples such as the Humanitarian OpenStreetMap Team (HOT), whose work covers areas home to 933 million people, and Noora Health, which has equipped over 30 million caregivers with vital medical training. These successes set an exceptionally high bar, but they also highlight the very problem 100x was created to solve. Kieron Boyle identifies this as the sector-wide “absence of an organised capital structure that can take social innovations to scale.” The 100x model is a direct, strategic intervention to address this systemic failure. By combining catalytic funding with the deep intellectual capital of a world-leading university, it is building a new piece of infrastructure for the social sector—one that organises capital not just for organisational growth, but for the explosive scaling of proven impact models.
A New Blueprint for Sector-Wide Impact?
Ultimately, the 100x Impact Accelerator represents far more than a funding opportunity. It is a profound call to action for the third sector to embrace a new, strategic approach to growth—one that prioritises the “endgame” of the impact model over the mere expansion of the organisation. This disciplined focus on the pathway to scale, rather than just the immediate results of a pilot, offers a compelling alternative to traditional grant-making. The success of initiatives like 100x, which intricately blend catalytic capital with deep intellectual and network support from a world-leading academic institution, could fundamentally influence the future of philanthropy. By demonstrating a viable method for identifying, nurturing, and scaling solutions to the billion-person level, it may provide a powerful new blueprint for how the world’s most urgent and complex challenges can finally be met.
