How far in advance should I book?

Two to three months is comfortable, but ask anyway: short notice works surprisingly often. Send the date, the city and the audience and you get an answer within a day or two.

Every event is quoted separately, depending on format, length, travel and whether the talk is tailored. Ask for a quote through the booking form and you get a clear number, no hidden extras.

Which formats are available?

Keynote (30 to 60 minutes), live hack show, board or executive briefing, and half- or full-day workshops. Panels, podcasts and TV appearances are also possible.

Does he really hack live on stage?

Yes. Nothing is pre-recorded. The demonstrations run on the kind of devices and services the audience uses every day, which is why the message sticks.

English and Swedish, both natively. The content is the same, the language follows the room.

Does he travel internationally?

Yes. David is based in Sweden and speaks anywhere in the world. Most keynotes are outside Sweden.

Can the talk be tailored to our industry or audience?

Always. Boards, engineers, sales teams, students and the general public get the same depth in different language. Send a short brief and the talk is built around it.

What do you need on site?

One stage, one screen, one microphone and an internet connection. He brings the rest. Technical riders are sent after booking.

Is it fear-mongering?

No. The talks are funny, honest and useful. The audience leaves knowing what to do on Monday, not scared of their phones.
