The gap we're closing

Seaweed knowledge exists.
It just isn't accessible.

Europe's seaweed sector is growing — but knowledge about how to participate in it is fragmented across academic papers, industry networks, and a small number of established operators.

Tideline translates that knowledge into a guided, visual experience — so coastal entrepreneurs, marine businesses, and communities can genuinely engage with it.

📚
Locked in networks
Expertise sits with a small group of established operators.
🗺️
No clear path
New entrants don't know where to start or what order to learn in.
⏱️
Wasted seasons
Long learning curves cause people to miss critical planting windows.
💸
Avoidable mistakes
Licencing, siting, and market errors cost time and money.
