Hosanna Hali, Founder of The Tech Cornr, transitioned from business studies to the tech industry over five years ago after learning to code. Her dream role at Microsoft opened her eyes to the tech world’s potential—and its lack of diversity. Determined to change this, Hosanna launched The Tech Cornr in 2020, providing accessible career insights, learning resources, and advice on navigating the corporate world. Through her content, she’s helped multiple women kickstart their careers in tech. Her relatable approach quickly grew a community, leading to collaborations with top brands like Google, IBM, Logitech, Norton, Sony, and Amazon, as well as speaking opportunities at events such as Black Tech Fest, Oxford University, Warwick University, and Clifford Chance. A 2024 and 2025 Diversity Champion Finalist for the Black Tech Achievement Awards, Hosanna continues to support those entering tech through content, speaking partnerships, and events that connect and embolden her community.
