Unigrid
UNIGRID Inc. is a San Diego-based sodium-ion battery company founded in 2021 out of UC San Diego Ph.D. research by Dr. Darren H. S. Tan and Dr. Erik A. Wu. Its sodium chromium oxide (NCO) chemistry and alloy anode technology deliver fire-safe, fully passive batteries rated for 30,000+ cycles and -40C to 60C operation, sold as 12V starter batteries (Na+ Fleet), BMS-less rack modules (Na+ Module), residential energy storage (Na+ Casa), and DC rack systems for commercial, industrial, and data center use (Na+ Cleo). Cells are UN38.3 and UL 9540A certified. Backed by Transition VC, Ritz Venture Capital, Union Square Ventures, and Foothill Ventures via an oversubscribed $12M Series A (2024); shipped its first sodium-ion residential batteries in July 2026. UNIGRID publishes no public API or developer program.
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.
API Evangelist profiles Unigrid 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 — Unigrid scores 6.8/100 (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 Unigrid
Each block below is one kind of artifact we hold for Unigrid. 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.
