Knowledge Work bets vertical sales AI agents beat copilots; ¥3.5B Series C
Japanese sales-enablement startup pivots from SaaS to a Sales AI Agent OS and raises ¥3.5B led by Globis, with Ricoh, Canon and banks as partners.
Knowledge Work (ナレッジワーク)
What the business is
Knowledge Work builds and operates AI agents that boost sales productivity for large Japanese companies — consulting-built custom agents, standard sales AI products, and a new Sales AI Agent OS that layers company ontology, strategy, agents and interfaces.
Starting capital：¥3.5B (approx. US$23M) Series C 1st close via third-party allotment, August 2026, led by Globis Capital Partners; cumulative allotment funding ~¥9.7B, including a ¥4.5B Series B in November 2023.
How it started
Koji Asano, a former director at Link and Motivation, founded Knowledge Work in April 2020 with CTO Maya Kawanaka, a former Google software engineer, to fix Japan's chronically low sales productivity. The company launched a sales enablement cloud in April 2022 after raising about ¥1B, positioning itself around sharing sales collateral and know-how.
What happened
Knowledge Work raised a ¥4.5B Series B in November 2023 and grew to ~230 employees by mid-2026, with major deployments at NTT DOCOMO Business, Mizuho Bank and Nissin Foods. In August 2026 it launched the Sales AI Agent OS — ontology, strategy, agent and interface layers that let agents use each client's own sales data and strategy — and closed a ¥3.5B Series C first close led by Globis, drawing ten new corporate/CVC investors (Ricoh Japan, Canon Marketing Japan MIRAI Fund, NTT Docomo Ventures, SMBC, Japan Post Bank AM, MUFG Innovation Partners, Sumitomo Mitsui Trust Bank, Fukoku CVC, Dentsu Ventures SGP, Hakuhodo DY Ventures) for capital-and-business alliances.
How it ended up
Still scaling as of August 2026: repositioned from a SaaS vendor into a sales-focused AI agent company, with the ¥3.5B Series C and corporate partnerships aimed at accelerating adoption of its Agent OS; no exit or shutdown.
Background
Knowledge Work is a Tokyo startup that helps large Japanese companies improve sales productivity with AI agents. It started in April 2020, founded by Koji Asano — a former director at Link and Motivation — with CTO Maya Kawanaka, a former Google engineer, and launched a sales enablement cloud in 2022 that shares sales materials, know-how and learning content inside enterprises.
Its bet is vertical over horizontal: while most companies deploy company-wide copilots and chatbots, Knowledge Work argues those are failing (it cites MIT research that 95% of enterprise gen-AI deployments fail to deliver ROI) and that function-specific agents — built on each client's own sales ontology, strategy and data — are what actually stick. By August 2026 it had deployed at thousands-of-users scale at NTT DOCOMO Business, Mizuho Bank and Nissin Foods.
In August 2026 the company launched its Sales AI Agent OS (ontology, strategy, agent and interface layers) and closed a ¥3.5B Series C first close led by Globis Capital Partners. Ten of the new investors were corporate CVCs and banks — Ricoh Japan, Canon Marketing Japan, NTT Docomo Ventures, SMBC, Japan Post Bank AM, MUFG Innovation Partners, Sumitomo Mitsui Trust Bank, Fukoku CVC, Dentsu Ventures and Hakuhodo DY Ventures — turning the round into a distribution play: each partner brings its own customer base and sales channels to sell the agents through.
The pivot is deliberate: CEO Asano describes the company's evolution from a SaaS business into an AI-agent company, with cumulative third-party-allotment funding of roughly ¥9.7B behind it. The open question is whether vertical sales agents become a durable category in Japan's enterprise market, or whether corporate distribution partners capture the value.
What has to be true
- The bet is explicit and falsifiable: vertical, function-specific sales AI agents will outperform horizontal copilots in Japanese enterprises — backed by a cited 95% ROI-failure stat.
- The funding structure is a deliberate strategic decision: a ¥3.5B round in which 10 new investors are corporate CVCs and banks, converting capital into distribution.
- Traction is concrete and dated: thousands-of-users deployments at NTT DOCOMO Business, Mizuho Bank and Nissin Foods, ~230 employees, ¥4.5B Series B in 2023.
- It documents a real pivot: from sales-enablement SaaS to an AI-agent company with its own four-layer OS, a move many B2B SaaS firms are attempting but few have funded at this scale.
- Coverage is verifiable across first-party PR, independent SaaS media, and the investor (XTech Ventures) plus Nikkei, giving the case a clean paper trail.
What can be applied
When horizontal AI fails to produce ROI, vertical agents trained on domain data can be the wedge — and packing a round with corporate CVCs buys the distribution that pure product-led growth can't.
Aftermath
As of 2026-08-06, Knowledge Work is scaling as an AI-agent company: the ¥3.5B Series C 1st close (led by Globis, with 10 new corporate/CVC investors) funds the Sales AI Agent OS, with delivery accelerated through alliances with Ricoh, Canon, NTT Docomo and the participating banks. Deployments at NTT DOCOMO Business, Mizuho Bank and Nissin Foods remain flagship references; cumulative funding is ~¥9.7B. No revenue or valuation is announced; the watch point is whether corporate partners convert into paying pipelines and vertical agents beat horizontal copilots.
