Light Talk is a smart, AI-powered consultancy platform designed to revolutionize the way clients connect with expert consultants.

Inspiration

In today’s fast-paced world, getting timely access to expert advice is more critical than ever. Traditional communication methods like emails and scheduled calls often result in delays and missed opportunities. Research indicates that businesses utilizing mobile messaging (e.g., SMS) experience up to a 45% faster response time compared to email (SAS Insights). Inspired by this, we set out to create a platform that makes expert consultancy both fast and accessible—regardless of physical location.
