“Can an API-first, FCA-regulated custody and trading infrastructure — backed by Octopus Group's balance sheet and Kraken's migration playbook — become the dominant embedded investment platform layer for UK wealth managers and financial planners?”
Seccl was founded as an API-first embedded investment infrastructure provider, offering custody, trading, and payments rails to financial planners, wealth managers, and investment platforms. Acquired by Octopus Group (owner of Octopus Energy and the Kraken technology platform), Seccl has leaned into its parentage to position itself as the scalable, cloud-native back-end for UK investment propositions. The strategic bet is that incumbent custody and platform technology is too legacy-burdened, and that a genuinely API-first, single-instance architecture — combined with direct CREST membership and a strong CASS framework — can displace traditional custodians as the infrastructure layer under a new generation of digital investment platforms.
