NayaOne

NayaOne is a London-based "sandbox-as-a-service" platform that gives banks and large financial institutions a single point of access to hundreds of fintechs, datasets and pre-built test environments. The product is designed to compress the procurement and integration cycles that typically slow down bank–fintech partnerships from months into weeks.

The platform combines air-gapped sandbox environments, a vetted vendor marketplace and synthetic datasets that mirror real customer data without the compliance exposure. Banks use it to evaluate vendors, pilot AI projects and run technical due diligence before committing to procurement. NayaOne also operates the FCA's permanent Digital Sandbox in the UK and powers Valley National Bank's innovation platform in the US.

Founded in 2019 by CEO Karan Jain, NayaOne raised a $4.7M round in February 2024 led by EJF Capital, with participation from Valley Ventures and existing investor Carthona Capital. The company has since launched the first fully Saudi-hosted fintech sandbox under the Kingdom's Vision 2030 programme.
