SoftBank Vision Fund
SoftBank Vision Fund (managed by SoftBank Investment Advisers) is one of the world's largest technology-focused investment funds, launched in May 2017 by SoftBank Group and anchored by the Public Investment Fund of Saudi Arabia. Now operating across two funds (SVF1 and SVF2) with combined assets under management reported at roughly $150B+, the fund pursues Masayoshi Son's long "AI economy" thesis, backing high-growth companies across the AI stack: hardware and semiconductors, the software infrastructure to gather, process and deploy data, and the applications built on top of it. It typically writes large late-stage growth checks (Series C/D and beyond, often $100M to several billion) into 300+ companies worldwide, spanning enterprise software, consumer internet, health tech, fintech, logistics, transportation, frontier tech, edtech and proptech across the Americas, EMEA and Asia. Headquartered in London, with major offices in the US and Asia, its portfolio includes many unicorns and household names such as Arm, ByteDance, and Aurora.
Every SoftBank Vision Fund company that ships an API, scored the way a machine reads it — and why the biggest checks in venture buy the thinnest ceiling on the board.
SoftBank Vision Fund has 333 portfolio companies tracked on the APIs.io network, of which 333 (100%) publish APIs indexed here.
Its highest-rated API providers on the network are OpenAI, Treasure Data, Attentive, 6sense, Klarna.

Auto-generatedThe 330 portfolio companies with APIs in the catalog, backed by SoftBank Vision Fund, scored on the Kin Score. Every figure below is computed from the catalog — nothing here is written.

A facet is averaged over the members that carry it, not over the whole cohort — the “Scored” column is that count. Averaging an absent facet as zero would score our own coverage gaps as the providers’ posture.
| Artifact | This cohort | Catalog | Difference |
|---|---|---|---|
| MCP server (any) | 21% | 16% | +5 |
| MCP server (first-party) | 8% | 7% | +1 |

mcp_pct counts any mcp/ artifact including ones API Evangelist derived from the provider OpenAPI; mcp_first_party_pct counts only servers the provider publishes. Prefer the latter.
