About us

Origin by Ocean is a platform-based algae refining company based in Finland.

We believe that in order for things to happen at a massive scale, it has to be turned into an industry. One with a reimagined value chain.


Micro and macroalgae are viable crops to grow and harvest, but there's a huge difference in how it’s done. We want to do it right.

We discovered that with the right process, we can remove marine overgrowth and transform them into ecological, healthy and oil-free ingredients for everyday consumer products. Every product would ease the chokehold of eutrophication.
Our platform would empower people who love the ocean to harvest their eutrophied shores and turn it into a sustainable income.

The UN
2030 is at
the heart of
why we exist

Sustainable Development Goals (SDGs) guide our short- and long-term planning and operations. We want our people to know they are working toward real global goals, so the SDGs are the foundation of our hiring process too.

Global Goals

UN Sustainable Development Goals (SDGs)

Good health
& well-being

With bio-based chemicals we can eradicate hazardous chemicals and create a ‘new industrial standard’ for pollution and waste releases as well as health and safety in the chemical industry.

Decent work
& economic

We create opportunities for income generation more economic and social independency in communities along the coasts of oceans and seas.

SDG 12
& production

We remove invasive algae and nutrients from the oceans and reduce non-biodegradable waste. Our manufacturing is based on a circular model.


SDG 13
Climate action

We increase possibilities and opportunities for local communities to plan, act and manage climate change related issues through education and raised awareness.

SDG 14
Life below

We prevent and significantly reduce marine pollution of all kinds, from agriculture, marine plastic debris and nutrient pollution. We also improve the health of marine ecosystems by growing biodiverse seaweed forests.

SDG 17
for the goals

We create opportunities for income generation more economic and social independency in communities along the coasts of oceans and seas.

Régis Delatouche

Science Director Activist

PhD, Organic Chemistry

Marine organisms have always been a source of inspiration and wonder for organic chemists like me. They can produce a myriad of complex and unique molecules, making them beautiful and attractive for many applications. Algae are no exception. The valuable molecules they contain will benefit the planet and humanity. 

It's an exciting challenge for me to develop a sustainable way to extract, refine and unlock the full potential of algae-based ingredients.
