Start-up settlement in the Innopark Sigmundshall

With the company Aquapurna, the first start-up has settled permanently in the new Innopark Sigmundshall. Aquapurna was founded in 2020 and specializes in the development of cost-efficient technology for applications in land-based aquacultures.

For this purpose, the company has set up a research and development center in the Innopark of around 400 m2. Large water tanks are currently being used for breeding the first 120,000 shrimps.

"Innopark Sigmundshall offers us excellent conditions to operate our research facility," says David Gebhard, CEO of Aquapurna. "We see great potential in scalable local food production and want to further develop our technology in this field."

"We are pleased that Aquapurna, a very attractive start-up, has chosen our site," says Holger Seifart, who is in charge of marketing. "Innopark Sigmundshall is aligned to the requirements of innovative companies in all stages of development. With our existing infrastructure, we provide companies with ideal framework conditions."

Aquapurna is also one of four start-up companies in ROOTCAMP, the K+S incubator program. As part of this program, an additional project is currently assessing the feasibility of combining the raw materials and expertise of K+S with the know-how of Aquapurna to jointly develop new products for land-based aquacultures.
