Who is behind Sondari

Me, in one line

My name is Elio Collin, I'm the founder of Sondari and I build web tools solo, from Dijon, France. Sondari was born from a very concrete frustration: spending weeks building things… that nobody was waiting for.

Why Sondari exists

Most projects don't fail from lack of work, but because they answer a need nobody really has. I wanted a tool that flips the order of things: check demand before you produce, not after. Not a 50-page report, not a hunch — a measurable signal, in seconds.

Sondari cross-references real sources (Google, Google Trends, YouTube) to estimate the demand, trend, competition and purchase intent of an idea, then draws a score and a verdict from them. It's the tool I wish I'd had before my own failed launches.

My conviction (and what it isn't)

Data reduces the risk, it doesn't remove it. No tool replaces the moment a real customer pulls out their card. Sondari doesn't claim to predict the future: it saves you from spending months on ideas that fail at the very first question — “is anyone even looking for a solution?”. The rest is your execution.

What you'll find here

Beyond the tool, I write practical guides on idea validation, market research and launching micro-SaaS. Not regurgitated content: methods I actually apply, with concrete examples and usable data. If a guide helped you (or missed something), tell me — I keep improving them.
