Our take
Chatbots have been around for quite some time and have seen a few iterations over the decades. But chatbots can require heavy coding which is costly, time consuming and can only be executed by professionals. There was also a huge gap between user expectations and reality.
Landbot had the idea to create a drag-and-drop style bot-builder that doesn’t require coding to support custom conversation flows. This quickly proved to be popular with customers, and the company have grown exponentially, being trusted by thousands of leading businesses including Coca-Cola, Nestle and Prudential.
Back in 2021, Landbot acquired Morph.AI, a chat-based marketing automation tool based in India. This supported its expansion into the Asian market, as the company aims to secure a position for itself against competition from other players like ManyChat.
