Watch the story


Yazi is up against an age-old industry where client contracts have been in place for decades. As the underdog, the team needed to validate that Yazi's service could be faster, cheaper, and give access to previously inaccessible users. Accessing those first few clients was critical to test, learn and iterate.


Our goal was to build a low-cost, no-code MVP to validate the value proposition.

  1. The MVP was successfully built to deliver survey insights from customers using WhatsApp.
  2. A low-cost acquisition strategy was put into effect to acquire client companies.
  3. We leveraged digital marketing channels and implemented a rewards-based referral programme to onboard survey participants through WhatsApp.


Since the launch of the MVP in May 2021, the venture has achieved the R265,000 in revenue, 10 clients, and 12,000 survey participants.

Next steps

The success of the MVP provided the validation to build a scalable system that isn’t dependant on human labour. We are currently in the process of developing the platform.
