Justin Halsall

Justin is a startup founder, software engineer, master of ceremonies, conference organizer, community leader, and an all round charming personality with a life long passion for technology and development. He is a well respected moderator at tech conferences and pitch events, and a hackathon veteran.

As the founder of Record Once, Justin helps technology companies document their products without tedium. Previously he occupied the role of Developer Advocate for IBM in New York, where was the face of IBM’s outreach to developers and startups in North America and Europe. He has over a decade of startup and development experience and has occupied the roles of Technology Evangelist, Director of Developer Programs and Chief Technology Officer.

We were extremely happy with Justin Halsall as the moderator for our online event. He gave the event a special touch and managed to overcome small issues with video or sound while being polite, funny and professional. This took away the pressure that comes with events like these and I don’t think the event would have been such a success without him. Best choice we made for this event!

—Joscha Hofferbert, Head of Innovation, Vision Health Pioneers, 26 November 2020

Justin speaks about Innovation, Lean Startup, working with developers, marketing to developers, APIs, Hackathons and Startup life.

Justin is just amazing as a moderator: super professional, super flexible, super energy and super spontaneous!
