“I worked with Guillermo at HubSpot, where he partnered with our Conversational Marketing team on reviewing and improving our AI chat assistant. He moved easily between his own team and ours, joining our training sessions, learning our quality rubric, and applying it to customer conversations each week. Guillermo communicated clearly and was responsive and proactive in how he worked with people across teams. He brought a customer-facing perspective to a marketing-led project, which added useful context to how we looked at conversations. It was a pleasure collaborating with him, and I'd happily recommend him.”
