Feellow, in one sentence.

The digital mental health market is saturated with players who put profit above people. Platforms that resell your data to advertisers. Conversational chatbots that claim to understand you and, for the most vulnerable users, reinforce cognitive distortions instead of correcting them. Personal development apps that promise serenity in seven days.

Feellow was born from a refusal: refusing to confuse psychological vulnerability with commercial opportunity.

The starting idea is simple. When you live a difficult day, your brain doesn't preserve it as it was experienced. It reconstructs it, simplifies it, dramatizes it or erases it. This has been documented for decades in psychology: retrospective recall distorts real experience. As a result, when you arrive at your therapy session a week later, you work with a filtered version of yourself.

Feellow captures information at the moment it occurs, in daily life, in a few seconds. This method is called Ecological Momentary Assessment. It is validated by more than six hundred studies in scientific psychology. It's not a gamification feature, it's a research method.

Feellow is part of the broader movement integrating digital tools into psychological care pathways. Our position is clear: we are not trying to replace the therapeutic relationship, we are trying to give it better raw material.

In practice, your patient arrives at the session with a structured report: their mood day by day, the contexts flagged, the correlations detected between their sleep, physical activity, social interactions, and emotional state. You gain several minutes at the start of the session, and you work from facts rather than reconstructed memories.

You always have access to the raw data, not just the summary generated by the generative engine. Clinical control remains entirely on your side.

My name is Benjamin Lafitte. I am the founder of Feellow, and I want the person behind the project to be visible.

I was first an engineer in the energy sector for five years. A profession I practiced seriously, but which did not match what has truly interested me for a long time: understanding how the human mind works, and why some people get better while others sink despite their efforts.

I did a skills assessment. I took personality tests, conducted professional interviews, spoke to psychologists, psychiatrists, researchers. Everything converged. I enrolled in a psychology degree at IED Paris 8, with a master's conferring the title of psychologist as my goal.

At the same time, I began building Feellow. Not because it was the most profitable project idea I had in mind, I had others. But because it's the only one where I saw my values embodied without compromise.

I'm convinced of two things. First, that scientific psychology has a considerable lag in reaching the general public, and that this lag nurtures gurus, self-proclaimed therapist chatbots, and platforms that monetize suffering. Second, that technology can, provided it's framed by clear principles, help close that gap without widening it.

Feellow is my attempt to make these two convictions tangible.

I commit, to every person who will use the app and every practitioner who will trust it, to never compromising users' mental health for growth metrics, to never letting the generative engine substitute for a professional's clinical judgment, to never selling the data. If Feellow one day cannot exist while honoring these principles, then Feellow should not exist.
