Guy Wieynk and Nick Constantinou launch Business Planning Consultancy in the UK
The 24 Hour Business Plan brings battle-tested methodology and ex-CEO expertise to UK's most ambitious business leaders navigating critical transitions
Guy Wieynk and Nick Constantinou have joined forces to bring The 24 Hour Business Plan, a business planning consultancy that has delivered 200+ strategic plans across 14 countries over the past four years, to the UK.
The duo are co-founding the UK operation, bringing the proven framework that delivers complete three- to five-year strategic plans with detailed execution roadmaps in just 24 hours – replacing months of traditional consulting with immediate clarity and action.
The results from the consultancy’s launch operations in markets including Australia and Singapore, speak for themselves: 85% of companies grow in their first year after working with The 24 Hour Business Plan, achieving an average of 24% revenue growth.

Who The 24 Hour Business Plan Serves
The consultancy works with ambitious mid-market, scale-up and enterprise-level organisations looking for growth. Its approach is industry-agnostic and designed for organisations ready to move from discussion to disciplined execution.
"Most businesses lose 12-18 months during major transitions because they lack strategic clarity upfront," said Guy Wieynk, UK Co-Founder. "We've seen this from every angle – as operators, investors, and board members. Our framework prevents these expensive delays by delivering complete strategic alignment in 24 hours, not traditional timelines. We've now validated this across 200+ businesses in 14 countries, and we're bringing that proven methodology to the UK."
The 24 Hour Difference
Unlike traditional consultancies that produce strategy documents destined to gather dust, The 24 Hour Business Plan creates actionable plans through four intensive 6-hour facilitated sessions. Every workshop is led by experienced former CEOs and CMOs who have navigated the exact transitions clients face – whether building platforms, pivoting business models, or scaling operations.
The entirely digital process eliminates post-it note theatre in favour of real-time strategic co-creation. Within five minutes of completion, leadership teams receive a 14-slide summary designed for immediate use in board and management meetings.
"Strategy without execution is just expensive wallpaper," said Nick Constantinou, UK Co-Founder. "We've built a process that delivers both - complete clarity on where you're going and total alignment on how to get there. That's why 85% of our clients grow in year one, with average revenue growth of 24%."
Building the UK Team
The UK launch brings together a team of successful former executives across multiple sectors, each bringing decades of operational experience navigating the specific transitions The 24 Hour Business Plan addresses. The firm is actively recruiting additional ex-CEO and CMO advisors to meet growing demand from mid-market companies, enterprises, and ambitious SMEs.
Guy Wieynk brings over 25 years of C-suite experience, having established eight global studios at AKQA and served as European CEO of Publicis Worldwide and Global CEO of AnalogFolk. He has architected major business transformations including agency-to-platform pivots, and currently serves as board advisor and investor across multiple ventures including Untold Fable and Otomo, alongside co-founding the UK operation of The 24 Hour Business Plan.
Nick Constantinou brings over 20 years of digital transformation expertise, having led creative agencies and digital consultancies at the forefront of helping brands thrive in the digital space. At AKQA, he led offices to £40M+ revenue and delivered transformational work for Xbox, T-Mobile, Nike, and Coca-Cola. Nick has engineered business turnarounds, scaled consultancies, and created digital platforms serving 10M+ customers. His work has earned 100 major awards including 12 Cannes Lions. He continues to advise and invest in growth businesses alongside co-founding the UK operation of The 24 Hour Business Plan.
Looking Ahead
Building on the success of The 24 Hour Business Plan framework, the UK operation will launch High Performing Teams in the coming months – a complementary service helping leadership teams maximise their effectiveness once strategic clarity is achieved. The offering addresses the reality that even the best strategic plans require high-functioning teams to execute them.
