London-based consultancy Black Castle Capital Partners has been honoured with the prestigious Global 100 – 2026 award for Best Venture Capital & Private Equity Business of the Year in the United Kingdom. This recognition celebrates the firm's boutique expertise in guiding companies through successful and efficient fundraising processes, highlighting its significant contribution to the UK's financial services sector.
A Boutique Approach to Capital Raising
Black Castle Capital Partners specialises in providing tailored introduction services across three key areas: Private Equity, Venture Capital, and Real Estate. The firm operates with a lean and nimble structure, which allows it to combine institutional-level discipline with a hands-on, boutique approach. This unique model gives clients a strategic advantage when navigating complex funding rounds, ensuring they receive personalised support throughout the entire process.
Comprehensive Fundraising Support
The company's services are extensive, covering every stage of the fundraising journey. This includes document preparation, data room setup, and facilitating targeted introduction meetings. Black Castle Capital Partners supports clients from the initial fundraising preparation phase right through to a successful close, ensuring a seamless and efficient experience.
Philosophy and Global Engagement
At the core of the firm's philosophy are disciplined capital allocation, deep sector insight, and strong alignment with founders and partners. These components position Black Castle Capital Partners to identify and support high-quality opportunities responsibly. In December 2025, the firm demonstrated its global reach by presenting at the Alea Global Family Office Summit in the Middle East. There, it engaged with international family offices on topics such as private capital trends, governance, and long-term value creation.
Client Success Stories
The business represents promising enterprises like Kabuni, an AI sports coaching platform that showcases scalable innovation and strong market fundamentals. This reflects the firm's focus on assisting companies with long-term growth potential, while also helping them benefit from tax breaks available through the government's Enterprise Investment Scheme, commonly known as EIS.
Leadership Perspective
Richard Diaz, CEO and Founder of Black Castle Capital Partners, commented on the award, stating: "Being recognised with this award underscores the value of our boutique model and our commitment to creating long-term impact for the founders, investors and partners we work with." He added: "We remain dedicated to delivering selective, high-quality opportunities and working closely with clients throughout their journey."
This accolade not only highlights the firm's excellence in the venture capital and private equity space but also reinforces its role as a key player in supporting innovative businesses across the UK. The award serves as a testament to the effective strategies and dedicated client service that define Black Castle Capital Partners' operations.
