TL;DR

NodeX (NodeX株式会社, English name NodeX, Inc.; the brand is also written NODE X and read ノードクロス) is a Tokyo company founded on 2019-05-07 as CollaboGate Japan株式会社 and renamed on 2025-03-04 (corporate number 6011001127965, 国税庁 法人番号公表サイト). Its product, also called NodeX, gives IoT and edge devices a W3C decentralized identifier (DID): a Rust agent installed on the device handles device authentication, key management and end-to-end encrypted messaging (DIDComm) and sends telemetry to a cloud dashboard, NodeX Studio (docs, product page; Undated; accessed 2026-10-11). In 2026 the company describes the business as a zero-trust security platform for critical infrastructure and names defense and national security as its first target market (2026-05-12, Agent engineer posting; posting metadata dated 2026-09-29).

• Cumulative funding is ¥830M: a seed round of "累計2.3億円" via J-KISS stock acquisition rights (J-KISS型新株予約権) from 伊藤忠テクノロジーベンチャーズ, DNX Ventures and 株式会社ラック (2023-02-15), then a ¥600M プレシリーズA from DNX Ventures and ITOCHU Technology Ventures (2025-03-19).
• The company does not name customers on its own site. Its releases name joint projects with 東芝テック, PFU, NR-Power Lab (NGK and Ricoh joint venture) and MEEQ; in January 2025 it said the Japan Air Self-Defense Force had begun discussing collaboration with it, citing Reuters (2025-01-27). BRIDGE reported Toshiba and Mitsubishi Heavy Industries as adopters (2025-03-21).
• The team is about 20 people by the company's count ("20人ほど", job postings, 2026-09-29), which says it is growing from about 20 toward about 50. Other sources give 16, 13 and 11 (see Notes).
• Engineering: the agent is written in Rust (docs) and the service runs on Google Cloud (ISMS cloud certification scope). Current postings list TypeScript/React, Rust/Axum/SQLx, GraphQL, PostgreSQL/Bigtable/Redis and GCP/Vercel. The current Agent engineer posting requires native-level Japanese and allows full remote work within Japan, with a monthly in-office All Hands (posting; accessed 2026-10-11).

Basic

The ISO/IEC 27001 scope reads "IoTシステム向けセキュリティソフトウェアの研究、開発、企画、教育、販売、保守、運用及びアドバイザリー業務". The cloud security scope covers providing NodeX as a cloud service provider "及びGoogleクラウドサービスカスタマとしての利用" (ISMS-AC).

Programs, memberships and recognition. The company joined the Decentralized Identity Foundation (DIF), stating it was the first Japanese startup to do so (2021-03-10), and the CEO has been DIF Japan Chair since 2022 (2026-05-12 speaker bio). Other items: Garage+ (Taipei) Startup Global Program Batch 12, 2021-11-01 to 11-05 (2021-11-16); Renesas Ready Partner for the RA and RX microcontroller families (2022-06-08); a project with 東芝テック selected for the Digital Agency's "Trusted Web の実現に向けたユースケース実証事業" (2022-09-13); and BRIDGE's "HOT100 with Accenture Ventures" (2025-04-30).

Identity and legal entities

The legal continuity between CollaboGate Japan and NodeX is established by the register (same corporate number). The CollaboGate name still appears in company infrastructure: the security policy and hiring policy are hosted on collabogate.notion.site, HERP job links on the careers page use the path /v1/collabogate/, and the 2026-05-12 release lists contact@collabogate.com as the press contact (careers, 2026-05-12).

Market context as stated by the company

• Edge devices outnumbered mobile devices from 2018 and are forecast to reach 275 billion, 94.5% of all devices, by 2035; building a zero-trust data platform in-house would take "2〜3年の期間と数十億円の初期投資" (2025-03-19).
• Japan's defense budget has grown to about 2% of GDP ("2026年度 約9兆円"), and the company states that Ministry of Defense procurement notices already include zero-trust device authentication as a requirement (posting, 2026-09-29).
• The company frames device, robot and AI-agent identity as "Non-Human Identity（NHI）" (2026-05-12).

Product

The documentation describes NodeX as "IoTシステムのオブザーバビリティ（可観測性）を確保するためのプラットフォーム": developers integrate NodeX Agent into a device so that its telemetry is collected securely into NodeX Studio in the cloud (docs; Undated; accessed 2026-10-11). The website presents three components (product page).

Components and feature areas

Agent data defaults: metrics are collected every 15 s (configurable 5–300 s) and sent every 60 s (60–3600 s); events are strings up to 255 bytes; logs are strings up to 1 MB that are not viewable in Studio and are only forwarded through the archive function; default retention is 14 days for all four types (docs).

How the company has described the product over time

Commercialization

No public price list was found. The company describes NodeX as delivered "SaaS提供" and says customers can start "ライセンス契約後、わずか1週間" (nodex.inc); use-case pages say agent integration takes about 1–2 weeks after a user licence contract, followed by an expert team helping define service requirements over three to six months (use case, 2025-03-18). The agent binaries on GitHub may be used only under a separate written agreement, which the licence defines to include license, subscription, evaluation, proof-of-concept and distribution agreements (LICENSE, added 2026-09-18). The security white paper refers to "すべての契約プラン" without listing plans (white paper).

Reported scale over time

No customer count, device count or revenue figure is published.

Announced customers and partners

Third-party reports of customers: BRIDGE wrote that the platform "すでに東芝や三菱重工など国内大手に採用され" (2025-03-21); KDDI MUGENLABO Magazine refers to "東芝や三菱重工といった日本を代表する製造業との提携" (2025-05-12); a BRIDGE event report described the CEO's business as protecting communications of critical infrastructure "防衛省や NTT、電力会社など" (2025-07). The company's own releases do not name these customers.

Stated plans

• 2023-02-15: use the seed funding to hire engineers and business development staff globally (PR TIMES).
• 2025-03-18: remote control of utility equipment using LLM-optimized settings is "現在、顧客のフィードバックを得ながら開発中" (use case).
• 2025-03-19: strengthen the product and delivery teams and prioritize early-customer success; hiring engineers, product managers and business development (PR TIMES).
• 2025-05-12: according to the CEO, 2025–26 focuses on "ディープサクセス" for existing customers, followed by global expansion and growth in customer numbers once that is confirmed (KDDI MUGENLABO).
• 2026-09-29: grow the organization "20名規模から50名規模へ" (posting).

Inconsistencies across sources

• Head office. The register lists 東京都渋谷区円山町 (Navi渋谷V 3F) as the head office (record last updated 2025-03-19), and the 2026-03-02 MEEQ release gives 本社 as 東京都渋谷区. The company page, PR TIMES profile, job postings and ISMS records give Toranomon Hills Business Tower 15F (国税庁, company page, ISMS-AC).
• Office postal code. The company page gives 〒105-5515, which Japan Post assigns to 虎ノ門ヒルズステーションタワー 15F; the 2023-08-09 release and the culture deck's company overview give 〒105-6415, Japan Post's code for 虎ノ門ヒルズビジネスタワー 15F; job postings and the deck's work-location slide give 〒105-6490. All three accompany the street address 虎ノ門1-17-1 虎ノ門ヒルズビジネスタワー 15階.
• Headcount. 20 (culture deck, Ver.2025.03.10); "まだ20名未満の組織" (interview, 2025-03-10); 16 (company block on HERP job pages; accessed 2026-10-11); "20人ほど" (posting text, 2026-09-29); 13 insured persons at the Shibuya establishment (gBizINFO, pension-insurance data, undated); 11 (HERP Career, pension-insured basis, period to 2026-08). The sources use different measures and dates.
• Open source. The website calls NodeX Agent "オープンソースの軽量ミドルウェア" and says binaries and sample code are distributed on GitHub (product page, nodex.inc; accessed 2026-10-11). The repository README says the source is not published, the LICENSE states "It is NOT an open source license", and the examples were removed on 2026-01-19 (README, LICENSE).
• Round name. The company calls the 2025 round プレシリーズA; in the same release ITV's partner refers to "今回のシリーズAラウンド", and a BRIDGE article describes "総額6億円のシリーズAラウンド" (PR TIMES, BRIDGE, 2025-04-30).
• Seed round timing. The seed was announced on 2023-02-15. ITV says it invested in 2022 and DNX says its first investment was in December 2022; the DNX interviewer on the company's site refers to "2022年には2.3億円のシード資金調達", while the senior delivery manager's interview says "2023年に累計2.3億円" (DNX note, interview01, interview02).
• Start of standards work. The 2023 seed release says the company joined W3C and DIF "2019年から"; the CEO says he began attending DIF around 2018 and joined in 2019; KDDI MUGENLABO says he took part in W3C specification work from 2018; the 2026 postings say founding members have been in W3C and DIF "2017年から" (2023-02-15, interview01, MUGENLABO, posting).
• Supported platforms. The README lists "Linux kernel x86(32bit) & x86-64(64bit), FreeRTOS ARM Cortex-M33(32bit)"; the documentation lists Ubuntu, Debian, Yocto, macOS and Windows 10; release assets contain x86_64 and aarch64 Linux, Windows and macOS aarch64 builds and no FreeRTOS build (README, docs, releases).
• Cost of in-house development. The homepage says an in-house secure data platform costs "数億円"; the 2025-03-19 release says "数十億円の初期投資" (nodex.inc, PR TIMES).
• Tech lead's name. 川上 和良 on the company page and interview, 川上 和義 in the culture deck (company page, culture deck).
• Product release date. The CEO dates the NodeX release to "2023年8月"; the 2023-02-15 release already presents NodeX as the company's solution (2025-03-19, 2023-02-15).

Other

• Name collisions. The GitHub organization nodexinc exists (created 2022-02-13, no repositories, no profile metadata), with no link to this company found (GitHub API); github.com/Nodex is an unrelated user account from 2011. The domain nodex.io, used as the contact link in the 2026-03-02 release, is privacy-registered through a US registrar and did not resolve on 2026-10-11; the company's own domains are nodex.inc and nodecross.app. Other unrelated projects named NodeX appear in package and freelance directories. Facts on this page are tied to nodex.inc, the CollaboGate name or ノードクロス.
• Positioning shift. The company's descriptions moved from a DID platform for customer experience (2021) to IoT data security for manufacturers (2023), an edge zero-trust data platform (2025) and critical-infrastructure security with defense first (2026); see How the company has described the product over time.
• Media items on the company's news index include a front-page Nikkei morning edition item on 2026-08-10 and a contributed article in the radiology journal RadFan (July 2026) on "既存医療ネットワークにおけるサイバーセキュリティと医療機器保護" (news, RadFan).
• The CEO describes a change in sales approach in 2024. He says that from around January 2024 the company switched to presenting NodeX as a direct solution to each customer's pain, after a first year in which the product "なぜか刺さらない" (interview01, 2025-03-11).
• PR TIMES release 12 for this company returns 404, and the company's news index carries the MEEQ release under 2026-03-03 while PR TIMES dates it 2026-03-02 09:00.
