A plant-based alternative seafood company with ties to seafood giant Thai Union announced Tuesday it raised more than $5 million (€4.6 million) in a seed round to accelerate the company's growth and development.

The ISH Company, a startup planning to make a line of plant-based seafood alternatives, said the oversubscribed round was led by ACCELR8, with participation from Stray Dog Capital, and multiple angel investors. ISH has raised a total of nearly $10 million (€9.2 million) to date.

ISH -- whose name is an acronym for Innovative, Sustainable and Healthy -- launched its flagship product Shrimpish, a plant-based shrimp, in early 2022, and has more than 25 products in development, including salmon, cod, crab, and lobster alternatives.

The company's products are currently available to consumers in various restaurants, colleges, and universities across the country.

The funding news follows on the heels of the company's B Corp certification as well as a recent partnership with Thai Union.

A B Corp certification is tied to a company's ability to demonstrate key sustainability and transparency metrics.

In August, Thai Union's Chicken of the Sea, one of the largest shrimp and canned seafood suppliers to the US market, reached an agreement with ISH.

Under the terms of the deal, Thai Union and Chicken of the Sea Frozen Foods will use their marketing and distribution channels to "ensure alternative seafood protein options are available to new audiences at an affordable price point."

Thai Union is the world's third-largest seafood company by revenues, posting THB 141 billion (€3.8 billion/$4.4 billion) in sales in 2021. In addition to Chicken of the Sea, Thai Union's portfolio includes canned seafood giants John West and King Oscar.

Thai Union has been investing heavily in alternative proteins, from cellular seafood to plant-based items.

Last year, Thai Union launched alternative seafood dumplings under its plant-based food brand OMG Meat in supermarkets across Thailand.
