Welcome to The Stack’s One To Watch. Every week we pick out a notable startup and go deep on what they’re building, why they’re building it, and the trials behind it all.

While the early success of LLMs gave companies the ability to drastically improve their chatbots, the dawn of AI agents has opened up a whole new world of productivity for enterprise AI users and created a very active category of startups. HappyRobot is one of the newest unicorns in that space after it achieved a $1.2 billion valuation with its $143 million Series C round earlier this month. Since launching in 2022 with a focus on logistics, the Spanish-US startup has since expanded its platform for building AI agents to automate complex enterprise work across internal and external systems.

Co-founder and CEO Pablo Palafox sat down with The Stack to discuss that growth into new sectors, why the company is building its own voice AI models, and using forward-deployed engineers.
