Venkatarangan Thirumalai is a Generative AI keynote speaker, enterprise AI consultant, and founder-to-CEO advisor based in Chennai, India. An Honorary Microsoft Regional Director since 1999 and an IEEE Senior Member with over 30 years in software, he helps enterprises adopt Generative AI and advises founding teams of funded technology startups on growth strategy, leadership, team building, and service design.

He founded Vishwak Solutions in 1996, growing it into a global software services firm with offices in India, Seattle, and London, and later co-founded an AI-driven fintech startup in the US. His track record of foresight spans decades: he predicted mobile phones would become primary computing devices in 2003 and built a machine learning-powered news app years before Generative AI became mainstream.

His advisory practice, The Founder Catalyst, works at the intersection of AI strategy and business leadership — helping technology leaders make the transition from technologist to confident, decisive CEO. His approach is grounded in real business experience across Indian and global companies. His book, The Founder Catalyst, is a practical field guide for that journey, drawing on stories from companies including Microsoft, Tata, Nykaa, Airbnb, and Ogilvy.

Beyond enterprise work, Venkatarangan is a long-standing contributor to Tamil language computing and digital preservation through the Tamil Virtual Academy. He serves as a trusted advisor to the Dr APJ Abdul Kalam International Foundation, Rameswaram.

He is the author of two Tamil technology books: Nutpam, which makes consumer technology accessible to everyday readers, and Seyaligalin Kadhai, a collection of stories behind successful apps from around the world, originally serialised in Madras Paper. He regularly discusses Generative AI developments in Tamil on the Sapien Geno YouTube channel, making AI accessible to Tamil-speaking audiences across India and the world.

A blogger since 2004 at venkatarangan.com, he has published over 4,500 posts reaching more than 2.5 million readers. His writing spans technology, entrepreneurship, and everyday life — most often written with a hot cup of Madras filter coffee and Tamil film songs in the background. All three books are available on Amazon India and Amazon.com.
