Hang is a customer loyalty and engagement platform (originally a Paradigm-backed Web3 brand-loyalty company, now positioned as an AI-driven "autonomous marketing system") used by restaurant, beauty, apparel, and e-commerce brands to build and run tier-based membership and rewards programs. Its Partner API powers program memberships, points and activities, quests, challenges, puzzles, loot/mystery boxes, rewards and redemptions, balance/gift cards, tokenized rewards, program tiers and segments, plus point-of-sale integrations with Toast and Square and real-time webhooks. Brands can embed a white-labeled rewards portal or drive the whole loyalty experience programmatically through the REST API.
