Key Capital Partners is the UK's leading investor in small-cap businesses, targeting profitable, privately owned UK-headquartered companies valued between £5m and £50m. The firm invests £4m–£20m per deal through management buyouts, equity release and development capital transactions, focusing primarily on technology-enabled, healthcare and B2B services businesses in growing, dynamic markets. Key typically takes minority or majority stakes of 35–45%, partnering closely with entrepreneur-led management teams as their first institutional investor to provide not just financial capital but hands-on operational and strategic support — covering talent acquisition, governance, systems and commercial networks — to unlock transformative growth over a three-to-five-year investment horizon.
Notable quotes
“Our deal flow is pretty strong, in fact the strongest it's been, despite the macro-economic headwinds the economy is facing. We typically make two to three deals per year and we expect to achieve this or potentially do more due to the quality of our pipeline, but we won't invest in areas that we think will suffer in 2023.”
“We like to build businesses that have sustainable growth, putting in place the disciplines that PE is used to seeing, including on governance, industrialising sale processes and building scalable robust platforms. We have sold businesses to mid-market PE, but also to trade and the public markets.”
“Jamie, Jack and Ryan have built and grown a very well-run business providing a critical service in one of the UK's most important pieces of infrastructure. The dynamics of the market are hugely favourable and given CellTech's unique position, we are confident that we have backed a very valuable and attractive business which will continue to grow, expand and deliver for its customers.”
