What Whale Alert does

Whale Alert B.V. is a Netherlands-based blockchain analytics company founded in 2018 that operates a platform for real-time monitoring of large cryptocurrency transactions and on-chain market analytics. The core product is a web-based dashboard (with a mobile progressive web app) that surfaces whale alerts — transfers, mints, burns, and dormant-wallet activations — across more than twelve blockchains including Bitcoin, Ethereum, Solana, Tron, and Polygon, and 100+ digital assets. Underlying the product is a proprietary analytics engine that computes specialized on-chain metrics such as Realized Profit, Continuous HODL, Average Buy Profit Ratio (ABPR), Potential Profit, Stablecoin Supply, and Transaction Volume, supplemented by an AI-curated crypto news feed with sentiment and market-impact scoring. Entity-attribution data (e.g., labeling wallets associated with Kraken, Coinbase Institutional, or Aave) is layered in via a partnership with Crystal Intelligence.

The company serves three customer segments — retail and professional cryptocurrency traders, developers and quantitative researchers, and blockchain enthusiasts — through a horizontal, product-led go-to-market motion. Revenue comes from tiered self-serve subscriptions: the Alerts Plan at $14.95/month and the Alerts, Analytics & News Plan at $29.95/month, each with a 7-day free trial. A separate WebSocket and REST API product, accessed via developer.whale-alert.io, serves quant and institutional users. Distribution is overwhelmingly organic and top-of-funnel, with official channels on Telegram, X, Discord, Threads, and Bluesky collectively reaching 3M+ followers and driving 500K+ monthly unique website visitors.

Whale Alert is an independent, privately held company (Whale Alert B.V., registered in Diemen, Netherlands, KVK 76497291) with no disclosed institutional funding, a lean team of 1–10 employees, and CEO Frank van Weert as the named executive. The most significant recent corporate action was the December 2024 launch of a next-generation analytics platform that consolidated the company's alert, analytics, and AI-news modules into a unified product. Payment processing is handled through Stripe (fiat, Apple Pay, crypto for annual plans), and the platform has been cited in academic research on Bitcoin volatility and whale-contagion effects.

Direct peers

• Glassnode: Glassnode is a leading on-chain analytics platform offering institutional-grade blockchain metrics, market indicators, and dashboards. It directly competes with Whale Alert's analytics layer (Realized Profit, HODL, transaction volume) and shares the same target customers: professional traders and analysts.
• Nansen: Nansen provides on-chain analytics with smart-money wallet labeling and entity attribution across multiple chains. It overlaps with Whale Alert's multi-chain monitoring and analytics for traders, but focuses more on wallet intelligence than real-time transaction alerts.
• Santiment: Santiment delivers on-chain, social, and development activity metrics for cryptocurrencies. It is directly comparable to Whale Alert's analytics offering and shares the same retail-to-pro trader customer base.
• CryptoQuant: CryptoQuant provides on-chain data, exchange flow analytics, and market indicators for Bitcoin, Ethereum, and other major assets. It competes with Whale Alert on the on-chain analytics and trader-use-case dimensions.
• IntoTheBlock: IntoTheBlock offers AI-powered on-chain analytics, market intelligence, and risk metrics for crypto assets. Its product surface (dashboards, indicators, API) closely mirrors Whale Alert's alerts + analytics + API stack.

Emerging players

• Dune Analytics: Dune is a community-driven on-chain analytics platform where users query blockchain data via SQL. It competes for the same quant researcher and trader attention as Whale Alert, though its model is community-built dashboards rather than curated alerts.
• Arkham Intelligence: Arkham provides on-chain analytics with entity attribution and a marketplace for blockchain intelligence. It is comparable in that it surfaces large wallet movements and labels counterparties, similar to Whale Alert's "Unknown Whale 1" attributions.

Broad incumbents

• Messari: Messari is a broad crypto research, data, and analytics firm covering the entire industry. It overlaps with Whale Alert's AI-curated news and analytics functions but is a much larger incumbent with research, events, and index products beyond the alerts use case.
• Coin Metrics: Coin Metrics is an institutional crypto market data provider with network data, market data, and indices. It competes for the same quant/enterprise API customer as Whale Alert's developer product, with a more established institutional presence.
• Kaiko: Kaiko provides institutional-grade crypto market data, including trade, order book, and aggregated blockchain data. It is adjacent to Whale Alert's API business, competing for the same quant researcher and institutional data-feed budgets.
