We’re on a mission to help more people invest – and invest well. It’s a bold ambition, backed by firepower of Octopus, the £multi-billion investment group.
But we’re not just backed by Octopus – we’re part of it. As a purpose-aligned business, Octopus supports our growth with patient capital and a long-term commitment to transforming our industry for the better.
Together, we’re building a company that’s a delight to work with. And as proud B Corps we share the belief that profit and purpose should always go hand in hand.
I have hundreds of millions of pounds on the Octopus balance sheet that we can deploy into businesses that we’re helping to scale and Seccl is right at the very front of that queue
