Bitfusion Io

Bitfusion (bitfusion.io) was an Austin, Texas startup, backed by DCVC, that built "elastic AI" infrastructure software. Its FlexDirect platform was a transparent GPU/CPU virtualization layer that pooled network-attached accelerators (GPUs, FPGAs, ASICs) across TCP, RoCE, and InfiniBand into a single elastic compute cluster for sharing, scaling, and management of AI/ML workloads. VMware acquired Bitfusion in 2019 and folded FlexDirect into vSphere as vSphere Bitfusion (subsequently end-of-lifed). The independent company no longer operates, the bitfusion.io domain no longer resolves, and it exposes no public API, developer portal, or discoverable artifacts. Retained here as a DCVC portfolio record; defunct as an enrichment lead.

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

Bitfusion Io is tracked in the API Evangelist network. This page is the human-readable profile that sits on top of the machine-readable index we maintain at apis.io.

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 — Bitfusion Io 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.

Bitfusion Io is in the network as a tracked entity. We haven't yet indexed a public API surface for it — when one is published, the artifacts, score, and agent-readiness read will appear here automatically. The source repository is where that profile is built.
