Cerenovus

Cerenovus Inc. (cerenovus.ai) is a San Francisco AI software company backed by Y Combinator (S26 batch). Cerenovus is both the company and the product — earlier product names have been retired, and Compendium is its internal workspace rather than a public offering. It reads the records an organization already produces (email, contracts, invoices, ledgers, tickets, calendars, meeting notes and documents), resolves the same customer, vendor or person across systems into one entity, runs deterministic scans for countable problems such as duplicate payments, dormant vendors and missed discount windows, then uses models to investigate what the scans surface and returns ranked findings with every claim cited back to the source record. It is sold as eight standalone engagements — operational due diligence, value creation plan, post-merger integration, exit readiness, operational diagnostic, decision intelligence, operational foresight and early warning, and spend and vendor intelligence — to enterprises, middle-market companies, private equity firms, consulting and advisory firms, and corporate development teams. Cerenovus publishes no developer portal, API reference or machine-readable specification; the only machine surface found is an undocumented, OAuth-protected remote MCP server at api.cerenovus.ai/mcp. Not affiliated with the similarly named Johnson & Johnson MedTech neurovascular device business.

Cerenovus is profiled on the APIs.io network. Tagged areas include Company, Artificial Intelligence, AI Agents, Enterprise Software, and Decision Intelligence.

Cerenovus’ developer surface includes authentication and 23 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

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.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Agent readiness — checks not met, largest first (exact, from this profile):

Machine-Readable Contract +18 pts — api_specs includes an OpenAPI document
Agentic Access Contract +10 pts — agentic_access artifact present (x-agentic-access), graded by author
Idempotency +9 pts — OpenAPI mutating operations declare an idempotency key — a header, a request-body property, or a named de-duplication token whose own description says so (verified); else common[].type matches /idempoten/i (documented)
A2A Agent Card +8 pts — a2a/-a2a.yml manifest, graded on conformance.grade against A2A 1.0.0
Request/Response Examples +7 pts — share of operations carrying request/response examples; else an Examples / Code Samples link
Typed Event Surface +6 pts — AsyncAPI document, OR webhooks/callbacks objects in the as-published OpenAPI, OR common[].type includes Webhooks

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.
