Cactos

Cactos is a Finnish clean-energy company that designs, manufactures, and operates smart battery energy storage systems (BESS) for commercial, industrial, and grid-scale use. Its hardware line (Cactos Mylo commercial storage and Cactos Cardo backup power, built in part from second-life Tesla EV batteries) is paired with Cactos Spine, a cloud software platform that optimizes each unit for load shifting, peak shaving, demand-charge reduction, solar self-consumption, backup power during outages, and participation in electricity and grid-balancing markets. Cactos serves logistics, manufacturing, EV charging, agriculture, real estate, and commercial-property operators. It is a portfolio company of Union Square Ventures. As of this profile, Cactos publishes no public developer API, SDK, or API documentation; the Cactos Spine app at app.cactos.com is a customer-facing management console rather than a documented developer API.

human only

Index entry only — little beyond a description and a link, and nothing machine-readable enough for an agent to act on without a human reading the site first.

Kin Score

API Evangelist profiles Cactos the way a machine reads it — 1 machine-readable artifact, pulled from the provider's own public surface and indexed so a developer, an analyst, or an AI agent can evaluate it against every other provider on the network.

Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — Cactos scores 14.9/100 (minimal), with a separate agent-readiness read of 0/100 (human only). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.

Kin Score

This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance.

How we profile Cactos

Each block below is one kind of artifact we hold for Cactos. For each we say what it is and why it earns a place in the profile, then list every one we've indexed — capped at two rows, scroll within the panel for the rest.

Security Posture 1

Authentication, domain security, vulnerability disclosure, and trust-center signals — the evidence that a provider takes security seriously enough to document it. We profile it because you can't govern what you can't see.
