HubSpot Co-Founder and CTO Dharmesh Shah thinks chatbots are the "biggest wave" of technology innovation in the past two decades. 

At the company's annual INBOUND conference yesterday at the Boston Convention and Exhibition Center here, he championed the marketing and sales automation provider's GrowthBot.

Shah said the chatbots will connect marketers and sales teams to HubSpot's GrowthBot, which will marry artificial intelligence and machine learning with existing HubSpot's systems like customer relationship management (CRM).
