The Love Experiment: Once's Game-Changing Algorithm for Authentic Connections

"In 2021, the online dating industry still relies on outdated conventions from 40 years ago—a market built by men for men that perpetuates patriarchal stereotypes. Technology offers a chance to evolve, and that's exactly what we're doing with The Love Experiment," shares Clémence Lalande, CEO of the Once dating app. For users of dating apps, this rings true: platforms often prioritize superficial criteria, leading to quick swipes that overlook deeper compatibility. This approach has hit imposed limits, constrained by algorithms focused on volume over genuine, spontaneous connections beyond physical appearance.

Girl Power in Action

A 100% female team crafted this groundbreaking new algorithm, drawing on expertise from French psychoanalyst Fabienne Kraemer, British psychologist Danielle Haig, and renowned dating expert Charly Lester, founder of a leading matchmaking service. To build "The Love Experiment," they interviewed over 1,000 couples, unlocking insights from more than 9,000 years of married life. The core is a simple yet powerful 28-question quiz that maps your emotional profile across four key dimensions.

"Questions range from 'Would you rather dine with Obama or the Dalai Lama?' to 'Which superpower would you choose?' They explore your relationship to yourself, others, romantic partnerships, and your body," explains Fabienne Kraemer. "This reveals typical profiles among 16 archetypes, matching you with three compatible types you might not have considered. Our biases often lead us to the wrong matches." Complete the quiz to discover your profile—Detective or Pilot?—and unlock tailored connections.

"Contrary to the myth that opposites attract, our data shows success hinges on subtle shared traits for true alchemy," notes Charly Lester. "Users choose from three match types based on varying compatibility models." The algorithm displays your profile permanently, making appearance just one detail amid meaningful insights.

"Dating isn't binary—you can't swipe away a good or bad vibe so easily. The Love Experiment introduces more nuanced, human-centered online dating, and we hope it inspires change," concludes Clémence Lalande. Head to Once and experience it yourself.
