Investment thesis

Guinness Ventures specialises in Series A funding for UK-based scale-up companies across business services, healthcare, and consumer sectors. The firm targets ambitious British companies with clear vision, established revenues of at least £1 million, and management teams who understand their markets — 'not speculative ventures, but established companies looking to scale-up and capable of long-term, sustainable growth with the right backing.' Since 2010, Guinness has deployed over £340 million into more than 200 EIS, VCT, and IHT-qualifying companies, and has returned over £130 million to investors. Investment vehicles span the Guinness EIS Service, Guinness VCT, a Knowledge Intensive EIS offer, a Co-Investment Service for sophisticated investors, and the newly launched Guinness Founders SEIS targeting early-stage UK startups in B2B software, fintech, and digital health.

We've spent over a decade building the relationships, expertise, and infrastructure needed to identify and support Britain's most promising growth companies. The Guinness Founders SEIS is a natural extension of that work – giving investors access to the very earliest stage of the journey, where the right combination of capital and hands-on support can make the biggest difference.

Cerca is addressing a clear unmet need in brain imaging with a technology that combines scientific depth with affordable real-world usability. We believe the company is well positioned to become a global leader in next-generation neuroimaging and are pleased to back David and the team on the next stage of Cerca's already impressive journey.
