What's the story behind your product?

ComplyCube's answer:

In 2010, Dr Tarekj Nechma and Mohamed Alsalehi met while working at Barclays, London, UK, where both were part of a leadership development initiative in technology and strategy. They quickly connected over their shared ambition to modernise financial infrastructure and a common interest in intelligent systems, data architecture, and regulatory innovation.

Dr Nechma holds a PhD in FPGA-based computations from the University of Southampton, where his research focused on accelerating complex algorithms used in scientific and financial computing. Before joining Barclays, he worked at HP Business Labs, exploring the use of AI for enterprise decision-making. At Barclays Investment Bank, he held progressively senior roles including Product Manager, Programme Manager, and later Head of Enterprise Data Tools & Insights. There, he led multidisciplinary teams to develop in-house and third-party platforms that applied machine learning and analytics to meet regulatory requirements, improve operational efficiency, and unlock business value.

Mohamed Alsalehi began his career at Microsoft in Dublin, working as a software engineer on secure, cloud-based systems for the Xbox division. He later earned an MSc in Management from the London School of Economics and a BSc in Computer Science (First Class Honours) from Technological University Dublin. At Barclays and later at HSBC, Mohamed led major engineering and product initiatives. As Principal Product Manager at HSBC, he managed global teams that built platforms for intraday risk, P&L, and trade and position storage. He also modernised risk operations by migrating legacy systems to big data and ran a blockchain proof of concept with ISDA for managing bilateral derivatives.

In 2019, after nearly a decade working at the intersection of finance, technology, and regulation, they co-founded a peer-to-peer FX trading platform. As they moved toward regulatory approval, they encountered a major barrier: identity verification and AML compliance. The available tools were outdated, fragmented, and difficult to implement. APIs were rigid, documentation was locked behind NDAs, and developer support was minimal. Even after integration, much of the compliance logic had to be built in-house.

They realised the problem was not just tooling, but the lack of compliance infrastructure for modern digital businesses. In early 2020, they made a strategic pivot and began building the platform they had originally needed.

That platform became ComplyCube.

ComplyCube was created to make identity verification, AML compliance, and onboarding scalable, fast, and developer-friendly. It offers services including document checks, facial biometrics, liveness detection, sanctions and PEP screening, KYB onboarding, and continuous monitoring. These capabilities are delivered through flexible APIs, SDKs, and no-code flows, enabling rapid integration while keeping user experience clean and intuitive.

Today, Dr Nechma is CEO and Mohamed Alsalehi is CTO of ComplyCube. The company is headquartered in Canary Wharf, London, and serves clients in more than 200 countries and territories. It also operates across the Gulf Cooperation Council (GCC), the European Union (EU), and the United States.

ComplyCube is a certified Identity Service Provider (IDSP) under the UK’s Digital Identity and Attributes Trust Framework. It holds certifications including ISO 27001 and ISO 30107-3 PAD, and maintains full compliance with GDPR and CCPA. The company has been named RegTech Partner of the Year in 2024 and 2025, included in the RegTech100 and FinCrime50, and is consistently rated among the top platforms on G2, TrustRadius, and Capterra.

What started as a roadblock has become a platform that powers digital trust at scale. Today, ComplyCube helps businesses in finance, telecoms, e-commerce, and government onboard users securely, meet compliance standards, and grow with confidence.
