Data journalism platform distributing fact-based stories to 3,000+ media partners; public dataset content syndication plus Stacker Studio brand content marketing for sponsored research.
Stacker is a data journalism and content marketing platform that produces fact-based, data-driven news stories using publicly available datasets — generating thousands of articles annually about topics ranging from local housing markets to national health trends — and distributes this content through a network of 3,000+ media partners including regional newspapers, digital publishers, and local TV station websites. Founded in 2017 and headquartered in Chicago, Stacker combines editorial data journalism with a content syndication model that gives media organizations a steady stream of data-verified, royalty-free content.\n\nStacker's editorial team uses public datasets (Census, BLS, CDC, USDA, sports statistics, real estate data) to create template-driven data stories — "The 25 cities with the highest median household income," "States with the lowest vaccination rates" — that are locally relevant when filtered by geography and consistently accurate because they cite official sources. Media partners (newspaper chains, local TV websites, regional digital publications) embed these stories in their sites through an iframe or CMS integration to supplement their original local reporting.\n\nIn 2025, Stacker also operates a content marketing division (Stacker Studio) where brands commission custom data journalism content about topics adjacent to their products — financial services companies creating content about debt statistics, healthcare companies creating health trend content — as a brand-safe, editorial-quality content marketing format. Stacker competes with traditional content marketing agencies, ThoughtLeadership content syndication platforms, and data-driven PR firms for content marketing budget. The 2025 strategy focuses on growing Stacker Studio brand partnerships, expanding the media distribution network, and developing AI-assisted data story generation to scale content production.
Real-time error monitoring platform capturing production exceptions with full stack traces; intelligent error grouping and priority scoring competing with Sentry for developer debugging tools.
Rollbar is a real-time error monitoring and debugging platform that captures software exceptions, stack traces, and user context from web and mobile applications — enabling developers to identify, prioritize, and resolve production bugs faster by providing the full context needed to reproduce and fix errors. Founded in 2012 by Brian Rue, Sergei Grunin, and Cory Virok in San Francisco, Rollbar has raised approximately $17 million and serves developers and engineering teams at thousands of companies as an alternative to more expensive enterprise error monitoring tools.\n\nRollbar's SDK captures uncaught exceptions and manual error reporting in JavaScript, Python, Ruby, PHP, Node.js, Java, iOS, and Android applications, sending error data with full stack trace, user session information, request headers, and custom context to the Rollbar dashboard. The intelligent grouping engine consolidates similar error instances into single items rather than flooding the dashboard with duplicates, and priority scoring surfaces the most impactful errors (by frequency and number of users affected) at the top.\n\nIn 2025, Rollbar competes in the error monitoring market against Sentry (the leading open-source alternative with larger community adoption), Bugsnag (acquired by SmartBear), Datadog Error Tracking, and New Relic Errors Inbox. The error monitoring category has seen commoditization as broader observability platforms (Datadog, New Relic) have added error tracking as features within their comprehensive monitoring suites — making it harder for pure-play error monitors to justify standalone subscription fees. Rollbar's 2025 strategy focuses on its AI-assisted debugging capability (Rollbar AI analyzes stack traces and suggests likely fixes), growing its developer community adoption, and offering better pricing for small teams relative to enterprise-focused competitors.
