Without David Ogilvy, the world might not be drinking Guinness, moisturizing with Dove, or swiping an American Express.

Known as the father of modern advertising, Ogilvy didn’t just sell products. He built enduring brands. Iconic ones.

He was a meticulous researcher, obsessed with understanding the customer. But not through what they said. He had a deep skepticism of stated responses. His famous observation still rings true:

“People don’t say what they think, don’t think how they feel, and don’t do what they say.”

That was the 1960s. And still, too many campaigns today are grounded in guesswork, gut instinct, or at best, outdated surveys and focus groups.

Ogilvy believed that great advertising had to be rooted in real insight and behavior, not just creative intuition.

At Heatseeker, we couldn’t agree more.

That’s why we meet consumers where decisions actually happen:

• On their phones
• In their living rooms
• Mid-scroll

We test value props, messaging, and creative not in sterile labs, but in live feeds and stories. Where attention is real. Behavior is real. And choices carry weight.

Because market truth doesn’t live in a focus group. It lives in the feed.

And if Ogilvy were building brands today, we think he’d be right there with us; listening not to what people say, but watching what they do.
