Swift Tokyo, NSSpain, and iOS Conf SG, he is one of the most recognized French voices in the global Swift community.
Kenneth Schlenker is a French-American serial entrepreneur and the founder and CEO of Opal, the #1 screen time and focus app on iOS. He first envisioned a focus app in 2008 while working at Google - it took him 11 years to actually build it. After founding art-tech company ArtList (acquired by artnet), launching Bird's Paris operations, and building a $10M ARR business with just 11 people, he also runs Open Scout, a weekly newsletter covering early-stage startups read by investors at Sequoia, YC, a16z, and Accel.
Willow is a San Francisco-based AI voice dictation startup that replaces the keyboard with voice input across any app. Built by two Stanford dropouts, the product delivers sub-500ms latency, 40%+ higher accuracy than built-in dictation tools, and context-aware transcription that handles technical jargon and proper nouns. Backed by Y Combinator and a $4.5M seed round, Willow targets knowledge workers - engineers, managers, sales teams - helping them type 4x faster by speaking naturally. Enterprise customers include Uber, Gusto, Canva, and GitHub.
x1 is the world's most powerful AI app studio, built for iOS. It replaces chaotic AI demo generators with a structured, end-to-end system that takes builders from raw idea to a production-ready App Store launch - generating native Swift and Xcode code, not throwaway prototypes. With modular studios for product design, branding, onboarding, monetization, and growth, x1 is what happens when someone finally takes AI-assisted app development seriously.
ZeroSettle is a drop-in SDK that lets mobile app developers skip Apple's 30% cut on in-app purchases by switching users to direct billing - charging just 5% + $0.50 per transaction instead. Built by two former Apple software engineers and backed by Y Combinator (W26), ZeroSettle arrived at the exact moment the Epic v. Apple ruling cracked open a $150B+ market. Setup takes 15 minutes, and developers get instant Stripe payouts, built-in tax compliance across 190+ countries, and smart conversion flows to migrate existing subscribers - all without touching App Store rules.
