San Francisco multi-channel notification infrastructure API with pre-built in-app inbox, email, push, and Slack routing; YC W21-backed at $1.2M revenue competing with Knock and Novu for developer notification platform.
MagicBell is a San Francisco-based notification infrastructure platform providing developers with a unified API and pre-built UI components to deploy multi-channel notifications across in-app, email, web push, Slack, and mobile channels — without building notification infrastructure from scratch. Founded in 2020 and backed by Y Combinator (W21) with $4.5 million raised from BlueLotus Ventures, Cherry Ventures, and others, MagicBell generated $1.2 million in revenue in 2024 with an 8-person team, serving software companies that need complete notification systems delivered in days rather than months of custom development.
OpsLevel is a developer portal and service catalog for tracking service ownership, maturity scorecards, and production readiness across microservices.
OpsLevel is a developer portal platform that gives engineering organizations visibility into the services they operate, who owns them, and how mature they are relative to internal engineering standards. At its core, OpsLevel maintains a service catalog that maps every microservice, repository, and infrastructure component to a team owner, populating metadata automatically from integrations with GitHub, GitLab, PagerDuty, Datadog, and cloud providers. This catalog becomes the authoritative source of truth for answering questions like who to contact about a service, what tier of reliability it requires, and what dependencies it has — questions that are often unanswerable at engineering organizations that have grown past the point where everyone knows everything.
