LemmaTree aims to empower individuals and organizations with control of their verifiable data. In doing so, it seeks to inspire the building of disruptive businesses striving for transparency and portability within the digital credentials and identities space. LemmaTree comprises three businesses - Affinidi, Trustana, and GoodWorker, all of which are seeded and funded by Temasek, a global investment company headquartered in Singapore.

Affinidi is a core technology company focused on digital identity. We empower institutions to issue verifiable credentials to individuals and businesses, who gain ownership and control of their data. We partner with governments and stakeholders within the travel and aviation, healthcare, and technology space to build a trusted ecosystem that enables safe travels across the globe through Affinidi Travel. We also deploy decentralized technology and verifiable credentials to global businesses within financial services, including financial institutions, regulators, fintechs, and more, to redefine the way they serve organizations and individuals, through Affinidi Finnovate. Affinidi Finnovate is powering chekFIN, a decentralised credentials platform that allows financial institutions to obtain verified credentials about fintechs. Affinidi Finnovate also enables organizations to issue digital certificates which can be verified and shared online.

Join Affinidi and be part of the future of identity: secure, portable and controlled by the individual.

Affinidi empowers individuals and organisations with ownership and control of their verifiable data, to unlock value across borders and platforms.

Leveraging on the building blocks that Affinidi provides, trusted institutions and entities can issue verifiable credentials to customers, which can in turn be shared with other applications to access services in an open and interoperable ecosystem.

Currently undergoing development are three applications that leverage Affinidi’s technology: Safe Travel initiative, a digital medical credentials ecosystem to safely open up international air travel; Trustana, a curated B2B marketplace and trade platform connecting verifiable, international partners for seamless cross-border trade; and Good Worker, an online job matching platform for seasonal workers and employers in India.

Affinidi, along with the applications Trustana and Good Worker, are seeded by Temasek, a global investment company headquartered in Singapore.

We are building a motivated and entrepreneurial team who is passionate about identity, decentralization and technology to make this happen.
