What Diopas does

Diopas S.A. (Δίοπας Α.Ε.) is a privately held, family-owned Greek net manufacturer founded in 1958 and headquartered in Nea Michaniona, an industrial suburb of Thessaloniki. The company operates a vertically integrated production line, established in 2014, that converts raw yarn into finished custom nets across 76+ product types, supported by an in-house ISO 9001:2015-certified laboratory for tensile and friction testing and approximately 10,000 sq.m. of manufacturing facilities that began a doubling-phase expansion in 2018.

Diopas's product portfolio is organized around four verticals: fish farming (net cages, harvesting nets, bird-prevention nets, vaccination and health-treatment bags), commercial fishing (gill nets, trammel nets, trawl nets, purse seine nets), sports and recreation (football, handball, basketball, volleyball, tennis, water polo, archery, ski, and trampoline nets), and industrial protection (shading, windproof, and anti-bird netting), complemented by accessories (twines, ropes, lead ropes, wires, floats, corks, needles) and services (antifouling impregnation, repair, and quality/endurance testing). Differentiated specialty products include an internationally patented Pyramid Net co-developed with the University of Crete and the Hellenic Center for Marine Research that increases juvenile fish survival rates, "bulletproof" UHMWPE/Dyneema nets that are 3x lighter and reduce fishing fuel consumption by 20-30%, copper-fiber nets that eliminate chemical antifouling, COATFISH antifouling-coated traps developed with Aristotle University of Thessaloniki that remain nearly 100% clean after four months on the seabed, and dolphin-attack-reduction nets developed with the International University of Thessaloniki.

The business model is B2B custom manufacturing, sold directly to fish farms, fishing operations, sports facilities, and industrial customers via a sales-led motion with quote-based pricing. Distribution is direct from the manufacturing facility to Greek domestic customers and to export markets in Europe, Scandinavia, the Balkans, the Middle East, and Africa, supported by recurring participation in SeaFood Expo Global and an informative website plus social channels. Revenue is generated through one-time sales of nets and accessories plus ancillary services such as antifouling treatment and repairs; no disclosed revenue, public pricing, or subscription component exists. The company is 100% family-controlled by the third generation of the Diamantidis family, led by Simon Diamantidis, and has historically funded growth through operating cash flow supplemented by small EU/ERDF grants (€10,000 Innovation Voucher in 2021; €49,900 Competitiveness grant in 2023) and a circular-economy partnership with Healthy Seas that has recycled 28 tons of old fishing nets since 2017.
