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.
Notable quotes
“We invest in ambitious British companies with clear vision, established revenues, and management teams who understand their markets. These are not speculative ventures - they are established companies looking to scale-up and capable of long term, sustainable growth with the right backing.”
“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.”
