Visual knowledge management platform with spatial whiteboard for researchers; $1.2M revenue in 2024 with 30K paid users backed by YC competing with Obsidian and Notion for sensemaking.
Heptabase is a Taipei-based visual knowledge management platform that lets researchers, students, and knowledge workers organize complex information through a spatial whiteboard interface — placing notes as cards on infinite canvases, connecting related ideas visually, and enabling the kind of non-linear thinking that linear note-taking tools like Notion and Obsidian constrain. Founded in 2021 by CEO Alan Chan and backed by Y Combinator, Heptabase raised $2.2 million in funding, reached $1.2 million in revenue in 2024 with 30,000 active paid users, growing with an 8-person team.
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.
