Digital Identity for a mobile world


Digital Identity for a mobile world


1.5 billion people without an official ID


4 billion people without an address


6 billion people with a mobile phone by 2020


About 1.5 billion people worldwide do not have an official proof of identity. For this reason, they lack access to basic services like insurance, loans or mobile communication.

Our mission is to allow anyone to create a secure, self-sovereign digital ID based on personal data. On the fly, using any mobile phone on the market, no matter the telecom operator or type of phone.

Our solution empowers people to store and share personal data whenever and with whoever they want, thereby unlocking people’s access to these otherwise inaccessible services.

The Gravity ID augments, but does not depend on traditional paper based IDs, postal addresses or birth certificates.

The g-ID is based on personal data that is verified through peer-to-peer and third-party validation. The more data and validation checks, the more reliable it is.



All personal data is stored on a decentralised database and can only be accessed with consent from the g-ID owner. The platform fully complies with the European Personal Data Protection law (GDPR).

The service is accessible from any mobile device through a USSD menu or Smartphone App


Use Cases

Use Cases

Gravity allows anyone to create a self-sovereign, secure digital identity based on certified personal data. ID attributes can include biodata, education, health data, official identity documents or credit history. The data can be certified by peers or trusted third parties. We use blockchain technology to verify the authenticity of the certifications.

On one hand, our solution serves as a one-stop touch point to self-sovereign identity for our users. On the other hand, it allows NGOs, governments, financial services providers and other private sector entities to request rich, data augmented identity profiles from the end-users, enabling better and more personalized service delivery.

Humanitarian Aid

We aspire to improve the effectiveness and transparency of aid delivery by ensuring that the eligible beneficiaries of development programs receive what is due to them, avoiding loss of funds intended for beneficiaries due to corruption, misallocation and lack of oversight.

In a context where aid distribution is increasingly being programmed through digital channels, our goal is to improve the traceability and delivery of traditional aid distribution mechanisms by helping NGOs and aid agencies to monitor, evaluate and hence improve service delivery towards their beneficiaries,

KYC as a Service

How it works: On the fly sim-card registration for a faster, cheaper and more secure KYC.

For more than half a billion people in Africa, mobile operators are struggling with collecting and verifying the KYC information, also denying the ones who lack formal ID access to a SIM card or mobile money services.

We provide on the fly SIM card registration services to mobile operators, thus facilitating digital and financial inclusion by unlocking access to services for the bottom-of-the-pyramid.




Proportional identity scoring

We challenge the existing binary identity paradigm (ID / NO ID) which restricts access to services at the bottom-of- the-pyramid. Thus, instead of a binary identity, the relying party receives a proportional ID score that reflects the quality of the users’ ID attributes and the trust of the entities that submitted them. In addition, the relying party can also request specific ID data and thus perform an identity check augmented with personal data which serves to improve service delivery.

User-centered design for maximal inclusion

Our platform has interfaces for basic phones via a USSD menu. It doesn’t depend on other infrastructure like biometric scanners, but users can authenticate themselves using their voice. Additionally, any individual can sign up and incrementally build a trusted identity over time by adding credentials.

Self-sovereign, secure & provider independent

Data is stored on a decentralized database that can only be accessed and shared by the ID holder or their guardian. This also gives the individual the possibility to monetize and leverage data for the rest of their life. Empowering the individual with complete ownership and access permission control over their data lies at core of our mission at Gravity.

Leveraging & digitizing existing social validation mechanisms

We digitize several approaches that are already used in local communities to establish ID. For instance, in order to obtain an ID card in Kenya, an individual who doesn'thave a birth certificate can alternatively provide a written endorsement from the village chief or priest. By leveraging existing mechanisms of establishing proof-of-existence in local communities, we not only facilitate a quicker adoption of our solution but also leverage the confidence that individuals have in these existing mechanisms.

Local footprint

Our presence on the field in Nairobi puts us in a unique position by giving us access to local partners across Africa and an in-depth understanding of their needs and contexts.
