Perigon vs Massive (ex-Polygon.io) News: overview

Perigon

Perigon is an Austin, Texas startup founded in 2022 by Joshua Dziabiak and Josh Rickel, backed by a $5 million seed round that LiveOak Ventures led in February 2024. For developers its main draw is that the pricing page tells you what you will pay: Individual at $25 a month for personal use, Startup at $250 with limited commercial rights, and Commercial at $1,250 with real-time data, an SLA and SSO. Every tier returns enriched articles with entities, topics, summaries and story clusters from 230,000+ sources (per company website; independently unverifiable), and Monitors let you save a query and get matches on a schedule. Plan for the delay: below Commercial, data lags by an hour unless you pay for the real-time add-on.

Massive (ex-Polygon.io) News

Massive is the name Polygon.io took on October 30, 2025. The company was founded in Atlanta around 2016 by Quinton Pike, and old api.polygon.io endpoints keep working beside the new api.massive.com base. Its ticker news endpoint returns recent articles for a symbol with summaries, publisher details and an insights array giving a sentiment label and a one-sentence reason for each ticker mentioned. Sentiment only exists for articles published after July 2, 2024. Ticker news is included in every Stocks plan: the free Basic tier reaches two years of history, and Stocks Starter costs $29 a month. Official SDKs cover Python, Go, JavaScript and more, and flat files can be pulled from S3.
