Hyper 4

Hyper (heyhyper.ai) is a Y Combinator-backed startup building "the self-driving company brain" — a knowledge-management platform that assembles a centralized, self-maintaining knowledge graph from a team's emails, Slack, GitHub, calendars, and other work sources, then feeds that context back into AI agents and tools so they act with accurate company memory and require fewer repeated corrections. Founded in 2026 by Shalin Shah and Kanyes Thaker and based in San Francisco, the company was surfaced as a Y Combinator portfolio company and added to the API Evangelist network as an enrichment lead. As of this profile Hyper is very early-stage, publishing only a marketing landing page at heyhyper.ai with no public developer portal, API reference, SDKs, or machine-readable API surface yet available; this record captures verified company identity and will be re-enriched as a developer platform is published.

Hyper 4 is profiled on the APIs.io network. Tagged areas include Company, Artificial Intelligence, AI Agents, Knowledge-Management, and Knowledge Graph.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/hyper-4: open an issue to ask a question, or submit a pull request to add artifacts.
