Business

Rebase, Inc. operates under the vision of "Where It Starts", centering its business on the rental space matching platform "Instabase". The platform matches online space listers who wish to rent out their spaces with users who wish to use them, catering to a wide variety of purposes including meeting rooms, photo studios, dance studios, and party spaces. With over 47,000 listed spaces (as of May 2026) across all 47 prefectures nationwide, the company provides services to a broad customer base spanning both corporate and individual users. As ancillary services, the company also operates the food and beverage matching service "Instabase Plate" and the community event service "TOIRO".

Business Model

Space listers bear only a fee (up to 35% maximum) on space usage fees, under a fully success-based model requiring no upfront costs or fixed monthly fees. Under this scheme, space users pay space usage fees via online payment, which the Company collects in a lump sum before remitting the amount net of fees to listers; this Instabase fee revenue accounts for 96.9% of net sales (FY2026, ending March 2026). Since the structure directly links growth in total usage amount to net sales, the Company manages maximization of the number of uses and the number of listed spaces as key KPIs.

Company Strengths

As of May 2026, the company has more than 47,000 listed spaces, making it one of the largest rental space matching platforms in Japan according to the company's own research. In FY2026 (ending March 2025), total usage amount reached ¥7,444 million (up 14.9% year on year), and the number of transactions reached 1,692 thousand (up 17.5% year on year), reflecting continued expansion of customer-drawing power. The listed space count and reservation data accumulated since founding constitute a unique asset that competitors would find difficult to replicate in a short period.

The company holds two patents: one for search result optimization utilizing AI image recognition (Patent No. 7317408), and one for a system that seamlessly links space reservations with food and beverage reservations (Patent No. 6889429). Because all functions are developed entirely in-house, the company can flexibly and rapidly improve UI/UX and release new features, continuously achieving differentiation as a platform.

A fully success-fee-based pricing structure with zero initial costs and zero fixed monthly fees minimizes the entry barrier for space listers. By including value-added functions such as IoT device integration, compensation coverage (up to ¥100 million), reservation management functions, and double-booking prevention functions within the fee, the company promotes continued use by listers and achieves a steady increase in the number of listed spaces.

ENVALITH's Perspective

Operating profit for FY2026 (ending March 2026) fell sharply to ¥97 million (down 80.0% year on year), with the operating margin deteriorating to 4.5% (from 25.3% in the prior period). The company explains this as "aggressive upfront investment aimed at achieving dramatic growth," but while advertising expenses ballooned to ¥614 million (up 70% year on year) and total SG&A expenses swelled to ¥2,000 million (up 45% year on year), the company itself acknowledges that "the results of measures contributing to the short-term growth of Instabase have been limited." The forecast for FY2027 (ending March 2027) also anticipates a further decline in operating profit to ¥72 million (down 25.8% year on year), making it essential to make the effects of these investments visible in order to restore investor confidence.

Cash flow from investing activities for FY2026 (ending March 2026) expanded sharply to negative ¥331 million (from negative ¥91 million in the prior period), driven by ¥155 million in deposits and guarantee money paid in connection with the head office relocation and ¥106 million in acquisition of tangible fixed assets. Accounts payable also surged to ¥414 million (from ¥83 million in the prior period), and as a subsequent event, the company took out an additional ¥200 million in borrowings from three banks in April 2026 (3-month term, lump-sum repayment at maturity). While the cash balance remains substantial at ¥1,192 million, cash flow management in the first half of FY2027 (ending March 2027), when repayment of short-term borrowings and payments for head office relocation costs will overlap, is a point of focus.

As an external factor, the expansion of the space-sharing market driven by population decline, increasing vacant houses, and diversifying work styles is expected to continue over the medium to long term, serving as a tailwind for the company. On the other hand, intensifying competition may keep advertising expenses elevated for an extended period, making the timing of margin recovery uncertain. Furthermore, the single-service structure, in which substantially all of the company's revenue depends on "Instabase," inherently carries vulnerability to declines in service competitiveness or regulatory changes. The expansion of equity-method investment losses related to affiliated companies to ¥19 million (from ¥7 million in the prior period) is also a concern regarding the profitability of the investee.

Growth Strategy

Maximizing total usage value (expansion along three axes: number of uses, average unit price, and number of listed spaces) combined with upfront investment for breakthrough growth

Advertising expenses were increased to ¥614 million (up 70% year-on-year) to strengthen customer acquisition, while UI/UX improvements and repeat-usage promotion aim to raise CVR. The company acknowledges that short-term results in FY2026 (ending March 2026) will be limited, positioning the realization of investment returns as a challenge for FY2027 (ending March 2027) and beyond.

The company is promoting an increase in long-duration use, large-group use, and large-scale corporate use of rental spaces to raise the unit price of total usage value. Capturing corporate demand is expected to contribute to a structural increase in average unit price, though quantitative progress has not yet been disclosed.

In addition to acquiring listed spaces in existing categories, the company aims to increase the number of listed spaces by developing new space categories, expanding alliances with major companies, and utilizing vacant houses as rental spaces. The increase in vacant space supply due to population decline serves as a tailwind for the market environment.

In connection with the headquarters relocation, security deposits and guarantee deposits increased by ¥146 million, and ¥392 million was recorded as construction in progress. As a subsequent event, an additional ¥200 million in total was borrowed from three banks in April 2026 to cover relocation costs. This is positioned as an upfront investment aimed at building the organizational and infrastructure foundation for breakthrough growth.
