Looking to invest? Get in touch using the form below or email hello@socialinvestmentscotland.com.


At SIS Ventures we believe that impactful enterprises, those that deliver profit with purpose, should be the bedrock of society; supported with the full power of the investor community.

We seek a commitment from an entrepreneur to lock the social mission into their company; ensuring that social impact and financial success are symbiotic and the organisation is accountable for the impact it creates.

Our Approach

SIS Ventures seeks to work with outstanding individuals committed to creating long-term, scalable social impact. These are businesses that seek to combine more traditional business objectives with the creation of social impact at scale. SIS Ventures is a flexible investor and will look to co-invest alongside other mission-aligned investors.

Our Terms

A mission-led business embeds social impact into the DNA of the organisation; measuring success based on the triple bottom line of people, planet and profits. The social mission must be clearly articulated and locked in, beginning with intent and resulting in tangible outcomes.

Each investee company will receive one to one support from an independent impact advisor at the beginning of the investment ro ensure an effective mission lock is in place.

Diversity & Equality

SIS Ventures will back diverse teams with a positive and enabling culture; actively seeking founders from under-represented groups and ensuring appropriate equality policies are in place at investee level.


SIS Ventures is part of the Social Investment Scotland group and is authorised by the Financial Conduct Authority. We aim to support and grow high impact organisations through access to mission-aligned investment. Our goal is to become the go to investor and partner for social entrepreneurs. With the work of social entrepreneurs helping shape a more vibrant and cohesive economy, the experienced SIS Ventures team will support in creating greater social change.

Our first fund raises new capital, utilising both EIS and SITR tax reliefs, to support both social enterprises (like charities and community interest companies) and mission-driven businesses. The latter will be expected to lock in their social mission in return for investment, underlining the importance of purpose to the very foundation of their businesses. The fund will offer conventional financial returns alongside social and/or environmental returns by investing either equity or debt into purpose driven companies.
