PSF is on a mission
to build a better ecosystem for impact enterprises

Founded in 2022 by Ratna Kartadjoemena and Pandu Sjahrir, Paloma Sjahrir Foundation (PSF) supports early-stage impact enterprises in Indonesia by connecting them to potential strategic partners and investors. Championing environmental and social goals alongside financial returns, impact enterprises face unique challenges in their path to growth:



Climate tech startups require extensive experimentation and substantial investments to achieve commercial viability.[1]



Early-stage enterprises focusing on poverty alleviation often need 7+ years to generate outsized financial returns as they develop their business models in low-margin markets that involve heavy investments in stakeholder education.[2]


Solutions for Indonesia

Depth-focused, non-tech impact enterprises in Indonesia face a funding gap at the early stage (typical ticket sizes between USD 100,000 – 500,000).[3]



The funding gap between angel investors and venture capitalists pushes the need to build an investor network to accumulate funds.[4]

Our founders witnessed these challenges firsthand while nurturing the impact enterprises they invested in. Recognizing the immense value in extending their network’s reach to support these visionary ventures, they established PSF to connect impact entrepreneurs with potential offtakers, investors, and partners, cultivating a thriving ecosystem rooted in shared purpose and boundless potential.
