Australian tech giant Canva has snapped up two local artificial intelligence (AI) companies as the $60 billion firm looks to drastically expand on its humble beginnings as a creative design tool.Sydney-based Canva – which made its Rich List co-founders Melanie Perkins, Cliff Obrecht and Cameron Adams multi-billionaires – acquired fellow Australian AI tool Simtheory and marketing automation company Ortto for an undisclosed amount.The deal brings the number of Canva's AI acquisitions to eight since 2024, with a reported total of $400 million investment made in the rapidly-growing technology so far.LIVE UPDATES: Donald Trump says Iran wants him to 'keep bombing'Canva founders Melanie Perkins, Cliff Obrecht and Cameron Adams.
