What Stack does
Stack was a New York-based Web3 infrastructure company founded in 2023 that built blockchain-native tooling for on-chain loyalty points, programmable rewards, and decentralized identity authentication. Its core product was a points platform exposed through a TypeScript SDK that supported cross-chain operations and analytics, enabling developers to issue, manage, and integrate transparent, programmable loyalty mechanics across multiple blockchain networks.
The company's underlying technology combined on-chain points primitives, loyalty program logic, and self-sovereign identity services into a single developer-accessible layer, differentiated by its cross-chain TypeScript SDK. Stack pursued a product-led growth motion, distributing the SDK through developer communities for self-service integration rather than direct sales engagement. The intended revenue model was recurring subscription or platform access tied to SDK usage, targeting a horizontal segment of Web3 developers and businesses building loyalty-enabled applications.
In March 2024, Stack raised $3 million in seed funding co-led by Archetype and Coinbase Ventures, with participation from A.Capital Ventures and Scalar Capital, to accelerate development of its on-chain points and identity stack. By 2025, the company announced the shutdown of its consumer products, instructing users to sell remaining holdings into USDC and withdraw balances, marking a wind-down of operations.
