Luke Marsden, CEO of HelixML, discusses the company's focus on providing a private GenAI stack that allows businesses to run models locally while keeping sensitive data secure. Helix launched in December 2023, targeting enterprises with regulated environments that cannot use cloud services but are eager to leverage AI capabilities. Marsden highlights the importance of developer productivity and fine-tuning models, which is an area of growing interest as businesses look to control their own AI tools for more tailored and efficient solutions.
