What Plus Zero does

Plus Zero (주식회사 플러스제로) is a Seoul-based B2B organic growth consulting firm founded in 2018 that helps large Korean enterprises improve digital acquisition and conversion through a unified methodology spanning data infrastructure, search optimization, and conversion experimentation. Its core offering combines GA4 and Adobe Analytics implementation with BigQuery and Looker Studio dashboarding, SEO and emerging GEO (Generative Engine Optimization) content optimization for Google AI Overview and Naver AI Briefing, and CRO delivered via A/B testing frameworks including Adobe Target and the proprietary AB Engine. The firm operates as an official certified consulting partner with Google Marketing Platform, Adobe, and Salesforce, and serves 30+ large enterprise clients including Samsung, Mercedes-Benz Korea, LG Electronics, LG CNS, Amorepacific, SK Telecom, Hyundai, Nespresso Korea, the Shilla Hotel, H&M, Homeplus, ILOOM, Topten, UNICEF Korea, and Bithumb.

The company has built a portfolio of proprietary tools around the consulting practice: GEWRITER (AI-powered SEO/GEO content rewriting at 10,000 KRW per use), Voice Intelligence (a credit-based AI chatbot trained on brand reviews for GEO and content planning), the free Keyword Tool for Google and Naver demographic keyword research, the free AB Engine A/B testing tool launched after Google Optimize's discontinuation, JIPDA market analysis dashboard, and +Audience (a GA4-BigQuery-Salesforce integration solution for CRM audience expansion). These tools function both as standalone product offerings and as funnel entry points into the core consulting practice.

Plus Zero monetizes primarily through custom-priced multi-year consulting engagements scoped per project (covering GA4 setup, SEO/GEO, CRO, VoC, and A/B testing), supplemented by transactional SaaS revenue from GEWRITER and Voice Intelligence and freemium lead generation from the Keyword Tool and AB Engine. The go-to-market motion is consultative enterprise field sales led by dedicated success managers, targeting CMOs and digital marketing heads at Korean large enterprises, with all delivery conducted in Korean. The company has 11–50 employees, is privately held with no disclosed investors or parent company, and operates exclusively in the South Korean market.
