We strive to make our oceans healthy.

The health of our oceans is directly linked to all life on earth, yet 95% of our oceans are unknown. We believe that threats posed to nature and society, by e.g. climate change or plastic pollution, need to be tackled and understood using real-time, objective and automated tools. This is what we provide with our technology.

Our Team

Our passion for the ocean is shared with our passion for our unique technology. We share and enjoy responsibilities, love to be challenged and enjoy experiencing steep learning curves. We enjoy our journey together, both above and underwater.


Planblue is a spin-off company from the Max Planck Institute for Marine Microbiology (MPI-MM) in Bremen (Germany). At this institute, the ‘HyperDiver technology’ was originally developed for scientific purposes. Shortly after its first publication, many requests for the usage of the technology came from all over the world. The idea was born to commercialize the technology and make it available to anyone. With the support from the EXIST Start-up program, the accelerator Climate-KIC and the MPI-MM, our team engineered a unique and user-friendly product, the planblue technology.


Unlike studies of the earth’s atmosphere and land surfaces (satellites), changes to our seafloor remains largely undocumented. Oceans cover two-thirds of the earth’s surface, yet 95% of its seafloor areas are unknown. This is surprising to us, as monitoring changes to our seafloor is essential. Healthy seafloor areas are the fundament for healthy oceans, and our oceans are important to all life on earth (e.g., source of food, regulation of climate, carbon sequestration, coastal protection).

We believe that threats posed to nature and society by e.g. climate change or (plastic waste) pollution need to be tackled and understood using real-time, objective and automated tools. Our mission is to standardize seafloor monitoring, make our technology accessible to anyone, and establish a unique Seafloor Database that will benefit us now (e.g., climate legislation), as well as future generations.

Important note: Our technology is not to be used to exploit or damage our oceans.

Thank you for the great support!
