“Big Sur AI’s dedication to helping merchants cut through the noise and build lasting relationships with their customers aligns perfectly with our vision at Lightspeed,” said Sydney Sykes, partner at Lightspeed Venture Partners.

“We believe retailers will need a personalised approach to customer engagement that persists outside of the retail store. Big Sur AI is making that kind of customer relationship automatic,” added Sykes.

Merchants often struggle with low conversion rates despite significant marketing spending, and Big Sur AI aims to improve these experiences with more assistive and helpful interactions.

Co-founders Vinod Ramachandran and Arnaud Weber, former Google executives, launched Big Sur AI in 2023 to provide access to AI for retailers.
