Frequently Asked Question

We have gathered the answers to common queries about how Yazi facilitates revolutionary market research through WhatsApp, alongside a host of other insightful information.


How does Yazi Work?

Yazi is a Market research platform built on top of WhatsApp. You have the ability to script, design, edit, launch and analyse your results on our webapp. The questions are sent via WhatsApp and the participants interact with them there as if it is a normal conversation.


How is Yazi's Data Protection?

Yazi prioritises data privacy by anonymising information, employing robust encryption, and allowing database access only to authorised personnel through password and 2FA protection. We adhere to stringent security standards including ISO/IEC 27001, NIST, PCI SSC, and GDPR, ensuring no data sharing with external third parties. Our comprehensive Data Security Program encapsulates physical and logical security measures, data access controls, encryption, along with data backup, recovery, and a well-structured incident response framework. In adherence to GDPR's principles, we process user data with utmost transparency, and address data deletion requests promptly as delineated in our Terms of Service, providing you with control over your data.


Why WhatsApp

Our WhatsApp surveys boast an impressive response rate of 62%, showcasing superior engagement compared to traditional online surveys, especially valuable in reaching individuals with limited internet access. The low data cost of 10 cents per survey, alongside the prevalent use of WhatsApp in South Africa with a 95% penetration rate, facilitates nationwide representation, reducing financial and phone storage barriers.

The familiar and user-friendly nature of WhatsApp enhances participant comfort, while its pause-resume functionality ensures convenience in survey completion. Moreover, the recent WhatsApp API upgrade enables rich data collection through various media forms without incurring significant data costs, paving the way for nuanced longitudinal studies. This platform's habit-forming nature, reinforced by personal engagement from our researchers, makes it an exemplary channel for continuous and detailed market research.


How is Yazi's data quality?

  • Speeding - A completion time that is too fast indicates the respondent has not sufficiently comprehended the questions.
  • Gibberish checker - Checking that open text answers are not “gibberish” and can be understood as a sentence.
  • Straight-lining checker - Checking that the sequence of answers does not follow the same pattern - e.g. A, A, A, A, A, A
  • Red herring question - Intentionally placing “oddball” questions into the survey to see if the respondent was paying attention. We also ask questions that correspond with previous answers but are categorised or worded slightly differently.
  • Evidence question - Where we specifically need an audience that exhibits a certain behaviour or matches a certain demographic, we ask respondents to send a picture that proves they match/meet requirement.
  • Panel recalibration & assessment - We recycle demographic and behavioural questions every 4 months to compare against historical answers.

How many questions can I ask via WhatsApp?

At Yazi, we employ a multifaceted approach to recruit diverse and reliable survey participants. Our strategies include:

  1. Social Media Engagement: We actively recruit through various social media platforms such as Facebook, Instagram, LinkedIn, Twitter/X, and TikTok. This broad approach helps us reach a wide demographic spectrum.
  2. Partnerships: We collaborate with companies possessing extensive databases of customers or members. Through these partnerships, we invite individuals to participate in our surveys, ensuring a rich pool of respondents.
  3. Local Presence: In an effort to connect with communities, we've placed QR codes in spaza shop locations across South Africa. These QR codes direct individuals to our WhatsApp number, facilitating an easy sign-up process.
  4. Referral Program: We believe in the power of word-of-mouth. Hence, we have a referral program where existing participants can refer friends, family, and their network. We incentivise these referrals to encourage a broader participation.
  5. Demographic Information Collection: To mitigate bias and the incentive to provide untruthful responses, we gather demographic information before showing participants our surveys. This ensures the quality and reliability of our data.
