Mobile paywall A/B testing platform enabling remote optimization without app updates; 100M monthly views generating $50M in subscription revenue for customers at $3.6M ARR with 12-person YC W21 team.
Superwall is a San Francisco-based mobile subscription paywall platform that enables iOS and Android app developers to remotely configure, test, and optimize their in-app subscription paywalls without releasing new app updates — providing A/B testing infrastructure, revenue attribution, and a library of 4,000+ custom paywall templates that development teams deploy to increase subscription conversion rates. A Y Combinator W21 graduate, Superwall raised $6.13 million, reached $3.6 million ARR in 2024 with a 12-person team, and processes 100 million monthly paywall views generating approximately $50 million in new subscription revenue for its customers.
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.
