What 11:FS Foundry does

11:FS Foundry is the London-based software company behind FoundryOS, a cloud-native, API-driven SaaS platform that supplies the core infrastructure rails required to launch and operate regulated financial services propositions. The company targets fintech startups launching or scaling digital products, as well as regulated financial institutions and innovation teams inside global banks seeking to modernise legacy systems and accelerate new product delivery. FoundryOS is sold as an enterprise SaaS subscription with no publicly disclosed pricing; commercial engagement is conducted via direct enterprise sales initiated through a single 'info@' inbox.

The platform is built on a composable, modular architecture organised around four functional modules — Customer Lifecycle Management (KYC, AML, fraud), Asset Storage (accounts, wallets, custody, balances), Asset Movement (orchestration, scheduling, rules) and Asset Lending (origination through servicing) — supported by a no-code configuration layer (FoundryOS Console), an Operations Portal, Consumer Apps component toolkits, and a Marketplace of preconfigured templates and pre-integrated partner adapters. Differentiated technical components include multi-tenant cloud infrastructure aligned to ISO 27001 and SOC 2, a bitemporal data store powered by a strategic partnership with XTDB that enables point-in-time auditability, and an open adaptor model designed to avoid vendor lock-in. The platform is described as compressing time-to-market from concept to production to weeks rather than years.

11:FS Foundry Limited is a private limited company registered in England and Wales (company number 11418349) and operates as a wholly-owned subsidiary of 11:FS Holdings, alongside sibling firm 11:FS Pulse. The business was incubated within 11:FS Group from experience building banks such as NatWest Mettle and MOX and was formalised as a standalone entity around 2018. The company is small — roughly eight employees disclosed — led by CEO Dave Morris, with a recently appointed VP of Product Engineering, Head of Product, and Head of Client Success. No external funding rounds, named customers, pricing, or revenue figures have been disclosed in available materials.

Core offering

FoundryOS is a cloud-native, API-first SaaS platform that provides the core rails (onboarding, payments, ledgering, compliance, lending, and customer lifecycle management) required to launch and run a regulated financial services proposition. It is sold to banks and fintechs as composable building blocks configured through a no-code console and connected to external providers via an open adaptor library.

Product overview

FoundryOS is a unified, cloud-native SaaS platform for financial services product development. The core FoundryOS Platform serves as the foundational layer, providing all core rails for regulated financial services including onboarding, payments, ledgering, and compliance. The platform is built on composable, modular architecture with a no-code configuration system (FoundryOS Console) that allows configuration of solutions ranging from full banks to embedded payment offerings. Supporting modules include Customer Lifecycle Management, Asset Storage, Asset Movement, and Asset Lending, each handling a fundamental part of financial propositions. Additional tools include the Operations Portal for service management and Consumer Apps component toolkits for customer-facing applications. The FoundryOS Marketplace provides preconfigured templates and access to integrated partners via an adapter library for payment rails, KYC providers, and fraud systems.
