The Arāya Sie Fund is a UK-based investment vehicle launched by Triin Linamagi's Sie Ventures and Rupa Popat's Arāya Ventures, targeting female founders building in AI, deeptech, fintech, healthcare, and sustainability sectors. The launch comes against the backdrop of a persistent funding gap in venture capital, despite growing momentum across the European startup ecosystem, women founders still receive less than 2% of total venture funding in the UK and Europe. More than half of the fund's limited partners are women, a remarkably high proportion for the venture capital industry, in what the managers describe as a deliberate effort to broaden participation in the VC asset class as well as improve access to funding for female founders.

The fund is positioning itself as a specialist backer for women-led companies in frontier technology sectors, AI, deeptech, fintech, healthcare, and sustainability, that have traditionally struggled to attract early-stage capital. The collaboration combines Sie Ventures' founder programmes and angel network with Arāya Ventures' operator-led investment approach and fundraising expertise.
