Sign language relay service with a successful scaling strategy

DeafTawk is a for-profit start-up technology company based in Islamabad, Pakistan. It has developed a mobile application that connects deaf users with certified sign language interpreters in real time through video calling, used by individuals and businesses. Available on both IOS and Android platforms, DeafTawk has now been replicated in Singapore. Between 2018 and 2020 it has provided 94,000 hours of sign language interpretation to some 18,000 users across both countries.

  • As of November 2020, DeafTawk employed 1,100 sign language interpreters, growing 35 per cent compared to 2019
  • Over 500 users found employment using DeafTawk in job interviews


The general public is largely unfamiliar with sign language and there are shortages of qualified sign language interpreters.


Through the DeafTawk app, users can either choose ‘book now’ for instant interpretation via a video call, or ‘book later’ to schedule a specific time. With this option, users can specify the purpose of the call and choose an interpreter with relevant expertise. The service is available 24/7 for individuals, businesses, and institutions (e.g., educational institutes and hospitals). Organizations can book interpreters online and are matched to subject experts. Between 2018 and 2020, DeafTawk provided approximately 94,000 hours of interpretation in Pakistan and Singapore. Through the service more than 500 deaf users have gained employment and 79 have been enrolled in higher education.

DeafTawk employs over 1,100 interpreters and offers services in ten languages. To work with DeafTawk, interpreters must have at least two years’ experience and undergo a three-day training workshop. Interpreters are based online and can work anytime, anywhere per their availability.

DeafTawk’s revenue from July 2019 to June 2020 was US$175,000. US$110,000 came from monthly subscriptions from businesses and institutions offering the service. The remaining US$65,000 was from on-demand services offered to individual users.

After expanding in Pakistan following a pilot, DeafTawk launched in Singapore in partnership with SG Enable and Enterprise SG, and with funding from Accelerating Asia. It aims to further expand in Asia, with a target of three additional countries in the next five years. DeafTawk is currently looking to launch an Artificial Intelligence feature to translate into 26 languages and is also improving the app’s machine learning functionality.
