Refiant AI is a South African startup founded in 2025 by Viroshan Naicker, Siddharth Gutta and Mathew Haswell that builds software to compress and optimize AI models, reducing the compute and energy required to run them while retraining them to preserve performance. Its inference optimization lowers costs and unlocks capacity, improves latency for time-sensitive industrial systems, and enables edge deployment that keeps data private and sovereign; the team has demonstrated compressing a 120-billion-parameter open-source model to run on a MacBook Pro with just 12 GB of RAM. The team includes a former Google Cloud architect, a Cambridge doctoral researcher, and an engineer with NASA experience. In April 2026 Refiant AI closed a $5 million seed round led by California-based climate-tech fund VoLo Earth Ventures to build its platform, grow its team, and support enterprise partnerships.
