Josh's AI transformation consulting firm (JOSHUA & COMPANY) and Paul's AI development agency (SecondBoost) have grown, so since May we paused new feature work and kept the service running. It deserves a dedicated team that can grow it. Asking price: $35,000 (KRW 40M-50M, roughly $29K-$37K), open to offers. After an NDA we share the original PostHog and Paddle screens and the code; handover scope and duration are negotiable. Operated by Secondboost (sole proprietorship, South Korea), co-founders Josh and Paul.
