The SaaS Source — August 2026

This month’s roundup covers the latest innovations and developments from Japan’s SaaS industry, including a sales AI startup landing a ¥3.5bn round backed by major corporates, a vertical software platform for logistics and construction raising ¥3.17bn, an invoice-factoring fintech striking a capital alliance with a megabank, and a mortgage-tech platform crossing ¥10bn in cumulative funding through a hybrid equity-and-debt round.

Knowledge Work Raises ¥3.5bn to Launch Its Sales AI Agent Platform

Nikkei reported (in Japanese) that Knowledge Work, a Tokyo-based sales enablement AI startup, raised ¥3.5bn ($23mn) through a third-party share allotment on August 4, in the first close of a Series C round. Ricoh Japan was among ten new corporate investors in the round; Sumitomo Mitsui Banking and Sumitomo Mitsui Trust Bank invested directly, while Canon Marketing Japan, Dentsu and Hakuhodo participated through their CVC funds. The deal brings Knowledge Work’s cumulative funding via third-party allotments to roughly ¥9.7bn. Alongside the raise, Knowledge Work and Ricoh Japan announced a capital and business alliance to strengthen sales and product development. The company plans to grow its consulting and “forward deployed engineer” headcount by 100-150 people over the next three years to support AI agent rollouts at enterprise clients.

X Mile Raises ¥3.17bn to Push Vertical AI Into Logistics and Construction

The Bridge reported (in Japanese) that X Mile, a Tokyo startup building software for Japan’s “non-desk” industries, completed a ¥3.17bn Series C on August 4 led by growth investor Vertex Growth, taking cumulative funding to ¥6.96bn. X Mile operates a cluster of platforms for logistics, construction and manufacturing employers, including an HR and recruiting platform, a workforce DX/AI platform, and an M&A and vehicle-sales support business. The company will use the funds to build out vertical AI features and pursue acquisitions. Japan’s blue-collar labor shortage (the workforce is projected to shrink by 14.28mn people over the next two decades) has made non-desk industries one of the most closely watched vertical SaaS categories among domestic and cross-border investors alike.

OLTA Secures ¥2.5bn and a Capital Alliance With Resona Holdings

Kepple reported (in Japanese) that OLTA, operator of Japan’s pioneering online invoice-factoring service, signed a capital and business alliance with Resona Holdings on August 14, raising ¥2.5bn through a third-party allotment to the bank. The deal makes OLTA an equity-method affiliate of Resona and lifts its cumulative funding to ¥10.73bn including debt. Under the alliance, OLTA’s cloud factoring service, which buys SMEs’ outstanding invoices as an alternative to bank loans, will roll out across Resona’s four group banks, pushing its financial-institution partnerships past 50. The companies will also integrate OLTA’s cloud invoicing platform, INVOY, with Resona’s banking and payments functions, aiming to unify invoicing, payment and credit decisioning for small business customers in one workflow.

iYell Tops ¥10bn in Cumulative Funding With a Hybrid Series F

The Bridge reported (in Japanese) that iYell, which runs a cloud-based workflow platform connecting banks and homebuilders around Japan’s mortgage process, closed the first tranche of a Series F round on July 3, raising ¥1.315bn through a mix of ¥1.015bn in equity and ¥300mn in venture debt. The round pushed iYell’s cumulative funding past ¥10bn (¥10.68bn as of end-April) for the first time. The venture-debt portion came from a fund jointly established by Fivot and Resona Bank; the equity investors were not disclosed. iYell’s core product, “Ieru Dandori,” digitizes the traditionally paper-heavy mortgage approval process for lenders and housing companies. The company said the hybrid structure was designed to limit further equity dilution while strengthening its balance sheet ahead of a planned IPO.
