Stress-test the narrative. ### Before a major strategic decision Surface trade-offs you may have framed away. ### To stress-test a narrative Find the soft spots before someone else does. ### To expose blind spots before the room does Walk in knowing what you didn't know. ## A simple workflow, not a black box 1. Step 1 ### Context You describe the decision, the room, and what's at stake. 2. Step 2 ### Challenge loop PARRY surfaces assumptions, second-order risks, and blind spots. 3. Step 3 ### Sharper output Reframed issue · Second-order risks · Trade-offs exposed · Tighter narrative. ## Not generic AI. Not a board portal. Not advice. Built for what can't leave the room. Why it's different ### Board-grade challenge logic Built on 250+ governance intelligence articles. Challenges like a prepared board member, not a search engine. ### Perspectives, not recommendations PARRY exposes trade-offs and surfaces what you haven't considered. You make the call. ### Private decision rehearsal A dedicated workspace for stress-testing decisions before the room sees them.

[Read our full privacy commitment →](/privacy) ## Why this exists The pace of decisions, the volume of data, and the complexity of the stakes have grown exponentially. The space leaders have to think before deciding has not. Today's CEO is expected to read more, decide faster, and be wrong less — often alone, and often without a single private space to rehearse the hardest questions before the room asks them. Decision readiness has stopped being a luxury. It has become the work itself. But the practice of rehearsing high-stakes decisions still gets a fraction of the attention given to the decisions themselves. PARRY exists to close that gap. ## Who built this ![Founder photo — Sylvain Lyoen](https://amktutzmrmqglkylfyyy.supabase.co/storage/v1/object/public/assets/20251024%20Sylvain%20_Lyoen%20v1.1.jpg) ### Sylvain Lyoen Founder, Lyoen & Partners PARRY was built by Sylvain Lyoen, founder of Lyoen & Partners. Three decades leading complex transformations across North America, Europe, the Gulf, and Southeast Asia — most recently as Director, Agile Program Management at Publicis Sapient (Riyadh and Paris), and previously with Deloitte, Capgemini, and KPMG. Notable engagements include a €32M Telco-to-TechCo transformation in the GCC, a €11Bn B2B omnichannel rollout across EU and North America, and a 55-FTE digital factory built from zero in Dallas. PARRY is the sparring partner he wished had existed in every boardroom he sat in. PCA-certified · INSEAD TBAI · SAFe SPC · Based in Bangkok · Operating across SEA & GCC ## Sometimes one decision is the issue. Sometimes the issue is the operating system around every decision. If the problem is structural, Lyoen & Partners handles the broader Board Operating System redesign.
