We listen to your vision
Taking the time to understand the objectives of management, the business and other stakeholders
“The investment by MML marks a key milestone in the RSE growth story, providing new access to capital and confidence to pursue our ambitious plans. Our decision to partner with MML was founded on shared values and a goal to change the way water companies and industrial water users enhance their treatment processes.”
Iain McGregor, Exec Chair, RSE

We see opportunities differently
Creating value from original thinking, taking a fresh approach to every investment
"We were unsure whether private equity was the right route for our ongoing expansion. However, there was a real meeting of minds with MML who persuaded us of the merits of a genuinely growth minded partner. We have not looked back."
Nathan Bowles, CEO, Veezu

We leverage our experience
Gained across a 35-year track record of building market leading businesses
"We are excited to have an investor in MML who deeply understands our sector and has tailored an investment to allow us to accelerate our growth. MML's experience in the internationalisation, M&A and scaling people-based businesses is a great fit for our own ambitions. We are already working in partnership to deliver our exciting growth plans."
Ben Cook, CEO, Cosegic

We bring a global perspective
Having grown our business internationally, we know what it takes
"Our investor, MML Capital, has gotten right behind our strategy and gives us access to expertise, resources, and capital we didn't have as a relatively small partnership.
