Tokyo-based Fact Base raised a $28.8M Series D led by Insight Partners to push its ZUMEN drawing-management software from Japan into 14 countries worldwide.
Key Takeaways
- Fact Base closed a $28.8M (about ¥4.5B) Series D led by Insight Partners, announced November 2026.
- Insight also led the Series C of ¥4.4B ($28.5M) in November 2025; Artemis Ventures and MPower Partners joined.
- Valuation was not disclosed. ZUMEN now operates in 14 countries, up from 12 a year ago.
Lead
Fact Base, a Tokyo software company that sells cloud-based drawing management to small manufacturers, has raised a $28.8M Series D. The round, announced this week, was led by Insight Partners, with new investors Artemis Ventures and MPower Partners participating. The company did not disclose a valuation.
The round is almost the same size as the Series C that Insight led in November 2025: ¥4.4B (about $28.5M) then, roughly ¥4.5B now. Fact Base was founded in September 2022, so it has taken three priced rounds in about four years.
What Does ZUMEN Actually Do?
ZUMEN stores engineering drawings and related documents in the cloud so machine shops can stop passing around paper and PDFs. Fact Base says it targets small and midsize manufacturers. A Japanese SaaS publication's profile says the customer base is now extending to companies with more than 1,000 employees.
The company plans to connect the drawing archive to quoting, ordering, production and procurement. CEO Masataka Takeuchi said in the announcement that the product "began with drawing management, but our ambition goes well beyond digitizing drawings."
How Fast Is the Company Growing?
Fact Base reports revenue growth of 2.3x year over year and a 2.2x increase in ZUMEN users. The company operates from 16 locations: five in Japan and eleven abroad. At the Series C, it said revenue had grown about 16-fold over two years and that customer count had risen about 13-fold.
Growth is slowing from those two-year rates, which is normal at larger scale. The Japanese SaaS publication estimated annual recurring revenue at ¥3.5B to ¥4.5B and overseas revenue at more than 30% of the total. Fact Base has not confirmed either figure.
Why Is Insight Partners Back So Soon?
Insight returned because the Series C thesis, selling to small shops abroad with a Japan-built sales machine, is producing results. The firm made its first Japanese startup investment with the Series C. Leading a follow-on twelve months later suggests the early overseas numbers held up.
The flat round size deserves a skeptical read. A company growing at 2.3x could usually raise more a year later, and an insider-led round with no disclosed price leaves outsiders unable to judge whether the valuation rose. Still, two new investors joined, and the stated uses include governance upgrades and preparation for a potential IPO, which points to a company that sees itself as a listing candidate.
How Does Fact Base Sell Abroad?
Fact Base copies the playbook of Keyence, the Japanese factory-automation group where Takeuchi started his career and where COO Kensuke Sugimoto managed US and European business. The profile describes direct sales, including cold calls and door-to-door visits, run by local subsidiaries, with product localization secondary to building a strong local sales team.
That approach is expensive per customer but works when the product is cheap to deploy and the buyer is a small shop with few software options. Southeast Asia is the established market, the US push is underway, and Italy and Germany are recent entries. Europe is where tolerance for aggressive outbound sales and strict data requirements may test the model.
What Comes Next for Fact Base?
The proceeds go to overseas hiring and sales, ZUMEN feature development, new business lines and management infrastructure. The test is whether quoting and procurement modules can lift revenue per customer, since drawing storage alone is a narrow product. If the expansion modules work, ZUMEN becomes an operating system for small factories. If they stall, growth depends on adding customers country by country at a steady sales cost.
Outlook
Fact Base has raised about ¥8.9B across its last two rounds, both led by Insight Partners, and is spending it on a Keyence-style sales push across 14 countries. Undisclosed valuation and an unconfirmed revenue base limit outside scrutiny. The next milestones are US and European traction, the launch of workflow modules beyond drawings, and any move toward an IPO.
