The Mayo start-up, joined by internet pioneer Dr Dennis Jennings, plans to ramp up international expansion over the next 18 months. Peroptyx, a machine learning start-up based in Mayo, has raised €1.7m in a seed funding round led by Delta Partners to expand into more international markets. The start-up develops a platform that helps companies refine their use of artificial intelligence to improve business functions. According to the start-up, companies are still struggling with developing their AI and machine learning strategies even though the global machine learning market is tipped to worth €100bn by 2027.
