Heptabase vs Eventual
Side-by-side comparison of AI visibility scores, market position, and capabilities
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.
About
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.
Distributed workflow infrastructure platform for TypeScript developers; durable execution, event-driven coordination, and long-running process reliability for cloud-native applications.
About
Eventual is an infrastructure platform enabling developers to build distributed cloud applications with event-driven workflows, long-running processes, and reliable async coordination patterns that are complex to implement correctly on standard serverless infrastructure. Founded in 2022 and headquartered in San Francisco, Eventual provides a developer SDK and cloud runtime that abstracts the complexity of distributed systems coordination — event sourcing, workflow state management, saga patterns, and eventual consistency — into an accessible TypeScript/JavaScript API.
