PlusMargin (Plus Margin) is a Bangkok, Thailand based digital marketing and business consulting practice operating under the tagline "Connect | Engage | Convert." The firm focuses on inbound marketing strategy, personalized and AI-assisted marketing, buyer-persona development, and customer-journey mapping for its clients, and publishes Thai-language editorial content across marketing, business, advertising, technology, learning, insurance, and lifestyle topics. It was surfaced as a portfolio company of 500 Global — where secondary sources describe an earlier Singapore-founded "predictive persuasion" e-commerce personalization product — but the domain today serves a four-page consulting and content site with no trace of that platform. Enrichment on 2026-08-12 confirmed no product API, no developer portal, no SDKs on any package registry, no /.well-known/ discovery surface, no llms.txt and no agent card. The one callable, machine-readable surface is the stock WordPress REST API the marketing site exposes at /wp-json — 237 routes across 11 namespaces, anonymously readable for content — which is WordPress core's API rather than a product PlusMargin designed, documents, or supports.
