Sullivan Street Partners

Sullivan Street Partners is an investment firm that takes an operationally intensive and risk-pricing approach to complex situations in the UK and Ireland, focusing on primary lower mid-market buyouts. Headed by Layton Tamberlin, Richard Sanders, and Zeina Bain, the firm operates across various sectors including industrials, consumer, healthcare, business services, facilities management and financial services, investing in businesses that have underlying stakeholder, operational, or structural complexities. Sullivan Street plays a proactive, transformational role in its portfolio companies, and has built a 12-year track record of delivering outsized returns and successfully scaling businesses. It takes ownership or controlling stakes in companies through investing £20m to £50m of equity. Operational expertise at Sullivan Street is not an external resource but is inextricably involved at the highest level in all decision-making processes, risk judgements and structuring discussions. Therefore, the speed with which we can initiate these changes, projects or improvements is radically different from other firms.
