Company profile

researched Aug 2026

Spindl is a growth and measurement platform for onchain (Web3) applications, combining attribution, analytics, audience-building and advertising in a single product. It positions itself as the Web3 equivalent of Web2 analytics tools such as Mixpanel and Amplitude, letting teams see where their users came from and what they do inside an onchain app. Integration is done by calling a JavaScript library (@spindl-xyz/attribution) from an app's sign-in page and passing the connected wallet; the company states it then handles measurement regardless of which chain the app runs on, mapping user journeys from a click anywhere on the web through to onchain actions such as NFT purchases or token staking.

The product set includes custom dashboards and a ChartBuilder for building reporting (compared by the company to Looker or Tableau), audience definition based on both onchain and offchain behaviour (including which apps users interact with and which tokens they trade), short links that carry attribution across sources, campaign-level performance tracking and conversion-event tagging for actions such as mints and swaps, and referral/payout tooling that lets apps pay KOLs, community members or crypto publishers who referred users. Coverage of the platform describes analysis of retention, conversion flows and acquisition costs across social platforms such as X/Twitter and Telegram alongside onchain interactions.

Since 2024 Spindl has also operated a wallet-connected advertising network. Company posts describe onchain advertising launches, in-feed social ads with Phaver, Coinbase Wallet joining the Spindl ads network in April 2025, and Spindl ads launching inside the Base app in July 2025. Coinbase acquired Spindl on 31 January 2025, and the company now operates under Base, with founder Antonio García Martínez described as Director of Base Ads at Coinbase.
