Turtle Shell Technologies develops Dozee, a contactless health monitor that tracks users’ heart, respiration, and sleep patterns while they sleep and converts hospital beds to “step-down” ICUs.

Our investment

Description of the investment.

Through our Climate Innovation Facility, we have invested in Dozee's MillionICU initiative which aims to provide capacity in overburdened public healthcare institutions in India.

This investment will test the viability of Dozee’s patient monitoring devices as step-down ICUs in lower resource healthcare settings such as public hospitals. It aims to improve clinical healthcare outcomes for patients accessing public hospitals and improve healthcare workforce efficiency through access to remote patient monitoring and associated analytics. The investment could result in the upgrade of 11,000 hospital beds by 2029 serving 1.4 million patients.

Impact information

Applies to investments made from 2019 onwards. The tabs in this section define what we expect to achieve through the investment, assessing the potential impact of the investment against six dimensions of impact. You can find more details on our methodology of assessing impact here.



Improve health outcomes (SDG 3) through access to remote patient monitoring device for patients accessing public hospitals in India.


Primary Secondary

Our investment will support the expansion of critical care automation and nursing efficiency with DEWS (Dozee Early Warning System/Step Down ICU) in Indian public hospitals. This will lead to an improvement of clinical outcomes and patient safety for ICU/HDU patients in public hospitals in India and save medical staff hours (India has a large staff shortage especially for specialists).

  • Catalysing markets: Long-term demonstration of a business model at scale for enhancing quality of critical care in the public sector hospitals in India which have been severely impacted by COVID-19.


Stakeholder Geography Characteristics

India (key states – Andhra Pradesh, Telengana, Odhisha, West Bengal, Madhya Pradesh, Rajasthan, north east states). Majority of new deployment is expected in Tier 2/3 cities/towns.

Public hospitals in India are largely accessed by patients who are in the lower three quintiles. Company estimates suggest more than 40 per cent of the patients currently served by the 'MillionICU' initiative are women.

How much?

Scale Depth/Duration

Additional ~11,000-12,000 + beds upgraded depending on reuse of the device and serving 1.4-1.5 million + patients in the public hospitals by 2029 (at the time of investment, 26,500 patients served).

Depth: Dozee’s product leads to improved operational efficiency of medical staff, reduces patient mortality with continous monitoring and reduce chances of human error.


  • Financial additionality: The commercial market does not offer capital at all to meet the company’s needs.


Execution Risk
  • Relates to uptake of the product and deployment.
Alignment Risk
  • risk relates to devices serving patients only in public hospitals, mitigated partly by hospital selection criteria and reporting.
