What Guillaume brings to Certo
3 reasons Guillaume makes Certo stronger

He has also built AI for the French state: predicting fire and road emergencies for the Ministry of the Interior, and building PIAF at Etalab, a native French question-answering dataset published at LREC 2020. Before Certo he was a senior engineer at Twenty (YC23), the open-source CRM, working on Gmail and Microsoft mail and calendar integrations.
