Transforming legacy

The Octopus effect

Seccl is part of Octopus, one of the UK’s most successful privately held investment and technology businesses. The same group that redefined energy through Octopus Energy (and its technology platform, Kraken) is now applying its ambition, financial strength and customer-first culture to transform investments.

Kraken is one of the world’s most successful and scalable infrastructure platforms – proven to deliver complex, highly regulated migrations faster and more safely than anyone else in its market. We’re already applying its experience here at Seccl.

Recently, we migrated more than 300,000 Monzo investment customers without a hitch.

Octopus and Seccl partnership graphic

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
