He helps leadership teams decide what AI, and the technologies that follow it, mean for their business. He is on the Global Gurus list of the world’s top futurists (#8 in 2024, #1 in 2025, #3 in 2026), is a LinkedIn Top Voice, and Salesforce named him one of its 16 leading AI voices. He holds a PhD from the University of Technology Sydney, is a Certified Speaking Professional and Global Speaking Fellow, and has a 9.2/10 average keynote rating. He is the author of six books, most recently *Now What? How to Ride the Tsunami of Change*, which introduces his WAVE framework. He founded Futurwise, is based in Sydney, Australia, and works with leadership teams worldwide. ## The Intelligence Age Readiness Briefing (for leadership teams) The Intelligence Age Readiness Briefing, the Readiness Briefing for short, is how leadership teams work with Mark: at a leadership retreat, an offsite or a board meeting, or at a global town hall by hologram. Leaders leave knowing what’s coming, what it means for their business and what to decide first. It brings together briefing calls with the executive team, a keynote built around the organization, the Intelligence Age Scorecard as the evidence behind it, a copy of *Now What?* for every attendee, and the follow-up. Each option comes at one all-inclusive price (fee, travel and accommodation); prices are on request. The three options: - **The keynote:** clarity on what’s coming. A 45- to 60-minute in-person keynote, written for the organization’s industry, markets and strategy after briefing calls with its executive team, followed by 30 minutes of Q&A. - **The keynote and the Scorecard (recommended):** a keynote about the organization, not AI in general. Adds a confidential read from the organization’s own people through the Intelligence Age Scorecard, a keynote aimed at what its leaders most need to hear, a live dashboard and a PDF for the board, and a personal report and 90-day action plan for every participant. - **The keynote, the Scorecard and the publication:** the leadership’s thinking, on the record. Adds interviews with eight to 10 C-suite or board members by a former Wall Street Journal and Bloomberg journalist, with Mark as editor-in-chief, a report of 20+ pages (one version for the board, one for the market) and a board deck. - [Intelligence Age Readiness Briefing](https://www.thedigitalspeaker.com/intelligence-age-readiness-briefing/): the offer for leadership teams, its three options, and the questions a Chief of Staff will ask - [Book the Readiness Briefing](https://www.thedigitalspeaker.com/contact/?interest=leadership-retreat): the contact form, preset to the Readiness Briefing ## Key facts (verified 2026-10-19) - **Name:** Dr. Mark van Rijmenam, CSP, known as The Digital Speaker.
