Sebastian Mattsson is a 19-year-old founder from Sweden who fell in love with building things on the internet at an early age. After years of experimenting with digital marketing, design, and online businesses, he discovered SaaS and built his first products using AI coding tools - without being a traditional developer.
His first SaaS showed him a clear pattern: building the product was never the hardest part. Getting people to see it was.
After talking to dozens of founders and hearing the same frustration again and again- lack of time and clarity around marketing - Sebastian decided to build the tool he wished he had. That tool became Launchli.
Launchli is an AI-powered distribution engine that analyzes a product, audience, and tone of voice, then creates, schedules, and distributes content automatically while helping founders find people who already need what they’re building.
Sebastian built and launched the public beta solo in late 2025. Within 30 days, Launchli reached its first 100 users entirely through organic channels like Reddit, X, LinkedIn, and direct conversations - no ads, no budget.
Today, Launchli is growing steadily, generating recurring revenue, and proving one simple lesson: distribution beats features every time.
