d'Halluin is on his second software company. After building a messaging chatbot startup out of Paris-Dauphine's incubator, he now runs Guideflow, a demo platform whose paid plans start at $35 for a single seat.
Geoffroy d'Halluin is co-founder and CEO of Guideflow, an interactive demo platform founded in 2023 that turns captures of a product into guided demos, sandboxes, and demo centers for sales, marketing, and support teams.
Starting Sently
His first company was Sently, founded in 2017, a software tool that let brands send newsletters, articles, and videos to their communities inside messaging apps and answer them with chatbots, according to the Incubateur Paris-Dauphine. Sently was accelerated by the Paris-Dauphine incubator and by Pépite Starter at Station F. He co-founded it with Florent Clapié, the company's CTO, whom he met in a student parachuting course.
Launching Guideflow
He introduced Guideflow on Hacker News in November 2023, telling readers they could capture a first demo with the Chrome extension in about three minutes. Let me Start lists him as CEO and co-founder of the Paris company.
Building a Global Team
Guideflow says it has more than 25 team members on four continents, with hubs in San Francisco and Denver, Toronto, Paris, Singapore, and Tallinn, according to its about page. Its customer stories feature teams at Docusign, Amplitude, Gorgias, and ChartMogul.
