Saurabh Kumar, WhatsApp’s Lead Decision Scientist, has revolutionized the company’s marketing strategy through innovative data analytics. His role in developing WhatsApp’s first-ever brand tracker and pioneering tools to optimize global ad performance has been instrumental in driving the platform’s growth, particularly in key markets like India and Brazil. Kumar’s leadership played a critical role in launching privacy-focused campaigns ahead of significant election cycles in these countries, reinforcing WhatsApp’s commitment to transparency and user control during politically charged periods.
As a founding member of WhatsApp’s marketing analytics team, Kumar onboarded and led a group of data scientists dedicated to enhancing marketing campaign performance through data-driven insights. One of his most impactful contributions was the development of a brand tracker, a sophisticated tool that provides real-time insights into the performance of WhatsApp’s brand globally. This tracker allowed the leadership team to measure shifts in user sentiment following major events such as the launch of WhatsApp Business and WhatsApp Payments—two milestones that significantly boosted WhatsApp’s presence in the business communication and payments sectors.
His expertise was especially vital in addressing the challenge of misinformation and disinformation during election periods. Ahead of the general elections in India and Brazil, Kumar led campaigns aimed at educating users about WhatsApp’s privacy controls, including end-to-end encryption, blocking spam accounts, and toggling privacy settings. These campaigns were crucial as political advertising on private messaging platforms like WhatsApp, Messenger, and Telegram had raised concerns about a lack of scrutiny and potential misuse for spreading manipulative content. Kumar’s efforts ensured that WhatsApp users were well-informed and protected during these critical periods.
Beyond privacy campaigns, Kumar introduced a groundbreaking causal impact campaignmeasurement tool, which significantly sped up post-campaign analysis. By reducing the time needed to evaluate campaign performance from five hours to just 45 minutes, this tool transformed how WhatsApp’s Consumer Marketing and Facebook Growth teams measured their campaigns’ effectiveness. The ability to swiftly analyze data provided the company with a critical competitive edge, allowing them to make real-time adjustments to their advertising strategies.
Kumar’s contributions did not stop with these tools. He also developed sophisticated regression models based on extensive survey data, which improved the precision of WhatsApp’s marketing strategies. These models enabled WhatsApp to scale its marketing investments from $10 million to over $61 million annually, optimizing ad performance and ensuring that the company could effectively move key business metrics. By integrating quantitative data with qualitative marketing research, Kumar’s models provided reliable insights that guided WhatsApp’s global marketing initiatives.
He emphasized onthe use of Polytomous Ordinal LogisticRegression (POLR) to analyze survey data and identify swayable audiences—consumers on the verge of changing their perception of WhatsApp. Utilizing this method, Kumar developed user segmentation models for key markets such as India, Brazil, Egypt, and Indonesia, helping WhatsApp’s marketing teams tailor their strategies for maximum impact in these regions. According to him, “This innovative approach allowed WhatsApp to better understand its user base and create campaigns that resonated more effectively with different demographics.”
The impact of Kumar’s work extended to major product rollouts, including WhatsApp Payments, launched in India in 2020. Kumar meticulously designed experiments to evaluate the user journey through WhatsApp Pay’s conversion funnel, optimizing the onboarding process to ensure a seamless experience for millions of users. His efforts helped WhatsApp establish deeper partnerships with major Indian banks, including ICICI Bank and HDFC Bank, positioning the platform for long-term success in the fintech space.
Kumar’s data-driven innovations continue to shape WhatsApp’s marketing and business strategies. His brand tracker and analytical tools have enabled the company to navigate complex markets and remain at the forefront of the messaging app industry. By transforming how WhatsApp measures and improves its global ad performance, Kumar has played a critical role in positioning WhatsApp for continued growth in an increasingly competitive landscape.
