From Alberton to AI Stardom: Kiara Nirghin’s Bold Leap Into Silicon Valley

From orange peels to AI, the South African innovator is proving that curiosity, grit, and purpose can rewrite the rules of global tech.

At just 25 years old, Kiara Nirghin has done what few manage in a lifetime. Raised in Meyersdal, Alberton, the youngest of four, she first captured global attention in high school when she won the Google Science Fair for creating a biodegradable polymer to help crops survive droughts.

Today, she is the co-founder and CTO of Chima, a Silicon Valley AI startup generating tens of millions of dollars in profit, and reshaping how tech can serve humanity.

A painful illness that sparked a purpose

Before the science prizes and startup success, Kiara faced something few teenagers are prepared for: at age 13, she was hospitalised with bilharzia and bacterial meningitis. It was a turning point.

“If my brain could endure that pain,” she said in a TEDx talk, “imagine what it could achieve if used for something meaningful.”

After recovering, she became obsessed with understanding how the world works, even seemingly insignificant things. That led to her invention: a superabsorbent material made from orange peels and avocado oils. Her goal? Help South African farmers retain soil moisture during devastating droughts. The project earned her the 2016 Google Science Fair Grand Prize and $50,000 in scholarship funding.

From Stanford to Silicon Valley

With her prize money, Nirghin headed to Stanford University in 2018, completing her Master’s in Computer Science in 2023, with a focus on AI and Human-Computer Interaction.

Even before graduating, global tech leaders took notice. She served on the Facebook Tech Sustainability Board, joined the Google Impact Fund, and was selected for prestigious fellowships from Thiel Capital and Alexis Ohanian’s 776 Foundation.

Throughout, Nirghin stayed focused on using technology to solve real problems, blending innovation with advocacy to make change scalable.

Building Chima: AI made to collaborate, not replace

In 2022, she launched Chima alongside her sister, Nikhara Nirghin, a seasoned actuary and former exec at Goldman Sachs. Their mission? To build AI agents with human reasoning that support everything from marketing to compliance across major enterprises.

With $5 million in backing from Y Combinator, General Catalyst, Soma Capital, and tech investor Elad Gil, Chima quickly proved profitable, crossing the $40 million mark.

Rather than replacing people, Chima’s AI systems are designed to work alongside them, amplifying decision-making rather than automating it away.

A rising global voice for young innovators

Kiara’s influence reaches far beyond the tech world. She’s spoken at the United Nations, addressed global forums for STEM equality, and is a proud ambassador for Room to Read, promoting girls’ education across Asia and Africa.

She’s appeared in TIME Magazine, The Guardian, Glamour, and Forbes 30 Under 30, and published a motivational book for teens called Youth Revolution: Be the Change.

Her ability to blend hard science with heart-driven purpose has made her one of the most inspiring young South Africans of her generation.

Why her story matters

In a world where innovation often feels out of reach, Kiara Nirghin’s journey is a reminder that big ideas can come from small places, and that science, when fused with compassion, can change lives.

From watching her sister change a nappy to building one of Silicon Valley’s fastest-growing AI startups, Kiara is showing the next generation, especially young girls, that there’s space for them in the labs, boardrooms, and global stages of tomorrow.
