Kiara Nirghin, a brilliant young woman from Johannesburg, became a South African who launched a Silicon Valley AI firm at 22. Her journey, from winning global science competitions to being recognised by Google and Forbes, is inspiring a new generation of tech talent from South Africa.
She’s not just another success story. Kiara is building something that could reshape how people interact with technology, and she’s doing it with heart, innovation, and a vision that puts humans first.
From Johannesburg to the Global Stage
Kiara’s journey began in South Africa, where she showed an early passion for science and problem-solving. At just 16, she entered the Google Science Fair, where she developed a biodegradable polymer from orange and avocado peels to help soil retain water during droughts. Her innovation won the grand prize and earned her international recognition.
This early success opened doors to Stanford University, where she pursued a degree in computer science. She later completed a master’s in artificial intelligence and human–computer interaction.
Starting Chima: A Human-Focused Silicon Valley AI Firm
In 2022, Kiara co-founded Chima, a Silicon Valley AI firm focused on helping businesses automate repetitive tasks like admin, support, and content creation. She started the company with her sister, Nikhara Nirghin, who left her actuarial job to become Chima’s CEO.
Unlike many AI startups chasing hype, Chima’s tools are designed to be ethical, helpful, and practical. They assist teams with real tasks, making workplaces more efficient without replacing the human touch.
Being a South African who launched a Silicon Valley AI firm at 22, Kiara brought a fresh perspective to an industry often criticised for its lack of diversity and ethics.
Making Her Mark Globally
Kiara’s work at Chima quickly caught international attention:
- She was named to Forbes 30 Under 30 North America for artificial intelligence.
- She joined the Google Impact Fund Board, which supports tech for good.
- She serves on the Facebook Tech Sustainability Board, where she helps shape global discussions on responsible technology.
She’s also been supported by the Thiel Fellowship and 776 Foundation, both known for backing groundbreaking innovators.
Why Her Story Matters
Kiara’s success changes perceptions. As a South African who launched a Silicon Valley AI firm at 22, she’s proof that world-class tech innovation isn’t limited to the U.S. or Europe. She’s showing that young African women can lead and shape the future of AI.
She’s committed to ethical AI. Chima doesn’t just build software. It focuses on AI that supports human work, improves quality of life, and stays transparent.
She gives back. Kiara actively supports educational efforts, especially for girls in STEM. She’s involved with Room to Read, which helps young women around the world access education.
Staying Connected to Her Roots
Despite her international success, Kiara hasn’t forgotten where she started. She frequently talks about her South African roots and wants to invest in the local tech ecosystem. Her goal is to make it easier for young people across Africa to access tools, funding, and mentorship in tech.
Kiara believes in a future where more South Africans lead global companies, and she’s helping make that possible.
What’s Next for Chima?
Chima continues to grow, with plans to expand into more industries like healthcare, finance, and logistics. The company is also developing partnerships that focus on ethical AI development and responsible automation.
With Kiara’s leadership, Chima stands out in Silicon Valley for its inclusive approach to building useful and respectful technology.
In Summary
