Engagements are local. Mandate execution happens on the ground in Bangkok, Singapore, Ho Chi Minh City, Kuala Lumpur, Jakarta, Riyadh, Dubai, or wherever the client board sits. The methodology travels. We come to you. Invoicing is conducted under the Hong Kong entity. Local mandates can be structured through partner arrangements where required for tax or regulatory reasons. ### How we work - One senior operator embedded one day per week for six months - CEO-level cadence — not analyst-grade reports - Methodology transfer is the goal — Day 181, your team runs the system without us Zero consultant dependency from Day 181. Lyoen & Partners is not a consulting firm. It is a methodology firm. The methodology is the asset, the engagement is its transfer, and the success metric is the day we leave. ### Registered entity Lyoen & Partners Limited Registered in Hong Kong, China Governed under English law · HKIAC arbitration The founder ![Sylvain Lyoen](/images/sylvain.jpg) Sylvain Lyoen Founder, Lyoen & Partners [LinkedIn ](https://www.linkedin.com/in/slyoen) ## Built from inside the machine — not observed from the outside. Three decades inside the rooms where these problems live — boardrooms in Riyadh, digital factories in Dallas, transformation programmes across Geneva, Paris, Bangkok, and Ho Chi Minh City. The Board Operating System methodology emerged from all of it — not from a whitepaper, but from watching what breaks when complexity outpaces governance designed for a simpler era. The pattern is structural, and remarkably consistent across geographies, sectors, and business models. Lyoen & Partners exists to fix it. 3 decades, 4 continents Ex-Publicis Sapient, Deloitte, Capgemini, KPMG PCA-certified · INSEAD TBAI · SAFe SPC €32M Telco-to-TechCo (GCC) €11Bn B2B omnichannel rollout 55-FTE digital factory in Dallas Bangkok-based · Operating across SEA & GCC - 3 decades, 4 continents - Ex-Publicis Sapient, Deloitte, Capgemini, KPMG - PCA-certified · INSEAD TBAI · SAFe SPC - €32M Telco-to-TechCo (GCC) - €11Bn B2B omnichannel rollout - 55-FTE digital factory in Dallas - Bangkok-based · Operating across SEA & GCC ### The longer story Sylvain Lyoen began his career in the firms that shape global transformation: KPMG (1997–1999, Paris) on enterprise resource planning; Deloitte (1999–2001, Canada) on early B2B eCommerce; BCE Emergis (2001–2005, Montreal) building a 4,000-person matrix delivery model serving North American financial institutions. A decade in Switzerland followed: IATA (2005–2007, Geneva) on global aviation governance; Capgemini/Sogeti (2008–2011) on Swiss public-sector governance redesign — including frameworks adopted by federal agencies. Independent advisory roles followed at IMD, MSF International, ICRC, and Forex Club throughout the 2010s. In 2018, Sylvain joined d²X Expertise (Paris) as Managing Partner, leading governance and transformation mandates for European industrial groups. From 2020, Publicis Sapient as Director, Agile Program Management — first in Paris, then in Riyadh, where he led Gulf transformation programmes for state-owned and family-owned conglomerates. Notable mandates include a €32M Telco-to-TechCo transformation in the Gulf — delivering a Super App with AI-powered personalised journeys, integrated FinTech and AdTech; an €11Bn B2B omnichannel platform rollout across Europe and North America for a family-owned retailer; an integration framework connecting 170+ operating companies onto a common platform; and the establishment of a 55-FTE digital factory in Dallas (€10M → €14M annual budget). Across these mandates, Sylvain orchestrated agile delivery for 120+ engineers distributed across Russia, Serbia, and Montenegro for a FinTech scale-up; designed PMO and governance structures for programmes worth €10M to €100M+; and consistently delivered against tight regulatory and time-to-market constraints. The pattern that emerged across all of these mandates was structural: when complexity outpaces governance, decisions stall, the board cycle becomes the bottleneck, and the CEO becomes the integration layer between functions that should be talking to each other. Industry, geography, and revenue scale changed. The pattern did not. Lyoen & Partners was founded to address that pattern directly — not as a consulting project but as an embedded fractional engagement. The firm operates from Bangkok, serves Southeast Asia and the Gulf, and is built around a single principle: the operating system above execution must be transferred, not delivered. Day 181, the team runs without us. ### In their words "Real testimonials from Lyoen & Partners clients will appear here once formal references are released."
