A little bit about me in the 3rd personAward-winning movement builder, social entrepreneur and marketing strategist.
Nandini Jammi is a recognized leader in the world of marketing, advertising and brand safety.
As co-founder of Sleeping Giants and Check My Ads Institute, she spent nearly a decade at the helm of two high-profile organizations that have re-shaped media, advertising, politics and tech policy around the world.
Sleeping Giants has earned the highest levels of international acclaim — including the Cannes Gold Lion, Webby Award (both in 2019) and a nomination for the Nobel Peace Prize (2024).
She has been nominated AdWeek’s Personality of the Year (2022) and named as one of AdWeek’s Young Influentials (2022). Fast Company recognized her media firm Check My Ads (not to be confused with the non-profit she founded later) as one of the Most Innovative Media Agencies in 2022.
Nandini began her career in public advocacy when she anonymously co-founded Sleeping Giants in 2016, a social media campaign that successfully urged advertisers to block Breitbart.com, a leading source of disinformation and hate speech in the U.S., from their programmatic ad buys.
The grassroots campaign grew to over 300,000 followers, turned brand safety into an ad industry priority and led to a measurable collapse in revenues across the “fake news” ecosystem.
Building on the success of Sleeping Giants, she co-founded Check My Ads Institute, the first independent digital advertising watchdog to fight for regulation and accountability across the global adtech industry.
In 2021, she was the first to coin the term “disinformation economy” — now used widely to define the global business model she first uncovered in 2016.
An experienced communicator, she has partnered with and trained non-profit teams, Fortune 500 brands, students and journalists around the world in advertising, marketing and communication strategy.
Prior to her advocacy career, Nandini served as a marketing strategist across a variety of tech companies, including Clearbit (acquired by Hubspot in 2023), Remitly (a leading online money transfer service) and ProdPad (product management software).
She currently serves on the Board of Directors of Check My Ads. She also serves on the Advisory Board of Stop Funding Hate, a UK-based tech accountability organization, and is a Founding Fellow at One Humanity Lab, a leadership institute at George Washington University.
