Asparagopsis taxiformis, a red seaweed shown to cut enteric methane from cattle by 90%, had been difficult to grow. Symbrosia domesticated the species and built a land-based system to cultivate it. Its aquacultured feed ingredient, SeaGraze®, launched in late 2025. Symbrosia's commercial studies show beef cattle growing faster on the feed, which goes straight to rancher profit. We backed the team in 2019, before there was a product, and demand is now running ahead of supply.

pH sensing has long relied on a manual, labour-intensive process: calibrating the electrode by hand. As specialist aquaculture investors, we've felt that frustration firsthand. ANB Sensors has engineered a new class of pH sensor that self-calibrates. It's a true hardware innovation with room to scale well beyond aquaculture, into the other major industries that depend on accurate water measurement.

Women in Ocean Food (WiOF) is one of Hatch Blue's most successful venture programs, scaling across three continents since 2021.

Hatch Blue Consulting was commissioned by the World Bank Group to analyze high-growth markets for seaweed beyond traditional uses like human consumption, aquaculture feed, and hydrocolloids.
