FAQ & Financials

India/Seva Mandir

The form factor of a necklace was selected after talking to hundreds of mothers in the villages we serve and observing several children wearing amulets on a black thread for the purpose of warding off disease. The cultural fit of the necklace supports its potential for long-term, local adoptibility.
Mobile phone settings can be changed to display all text in the app in Hindi or in English.
We agree that necklaces are not customary everywhere in India, but we also agree with local tailoring of design to meet cultural needs. As we look to take this technology to new last miles, we will again have to rethink our design so that it conforms to local needs. For us, scaling up requires several steps to be completed beforehand; firstly, we must rigorously evaluate the value propositions of our system, both in terms of data collection efficiency and in terms of efficacy in engaging the community towards their health behavior.
Our team is based both in the US, primarily for development, design and research, but also equally grounded in India when it comes to implementation and evaluation of the project. Seva Mandir, our partner, has been engaged with these communities for 45 years. Our local team from IIHMR, Jaipur also brings tangible, on the ground experience working with the bottom of the pyramid in India.
Seva Mandir hires their own General Nurse Midwives (GNMs) to run monthly immunization camps. Local Traditional Birth Attendants (TBAs) and Bal Sakhis (Friends of Children) are also hired and trained by Seva Mandir to individually track mothers, educate them on health issues, and constantly remind them of upcoming immunization camps. The visiting GNMs also provide basic antenatal care which is required by the government.


The knot keeping the necklace on the child is very secure and will not come untied easily, thus ensuring that the data is with the patient at all times. However, in the case of emergency or discomfort, the necklace can be untied by an adult or the string can be cut off.
If a child comes to an immunization camp and has lost his or her necklace, the child can be searched in our system by name, mother/father’s name and birthdate. Once the child’s identity is confirmed, a new necklace can be reissued and updated with the child’s immunization history with a single tap.
We are open to different streams of financial support, from social impact investors, charitable donors and crowdfunders, to grants that are looking to validate global health innovations. We are also excited to engage in new partnerships whether you are an NGO, hospital, research institution or for-profit company. Together, we can work to enable new interdisciplinary collaborations that extend our current work.
There is potential to apply our system to a variety of use cases globally; for example, the KB app could be used for Tuberculosis drug therapy tracking, or the storage of emergency information such as blood type and allergies.
