SoVa

What SoVa does

SoVa (株式会社SoVa) is a Tokyo-based, venture-backed private accounting firm founded in September 2019 that offers a one-stop back-office subscription service for startups, sole proprietors, and small-to-medium companies in Japan. Its flagship product, the まるっとプラン (Marutto Plan), bundles bookkeeping, payroll processing, social insurance procedures, tax filing, company registration, tax-saving advice, and subsidy/grant consultation into a flat monthly fee starting at ¥29,800 (excluding tax), with pricing tiers scaling to 5-, 10-, 20-, and 30-employee company sizes. Customers enter through online inquiries followed by inside-sales-led consultations, supported by an owned-content marketing funnel that includes the 税理士お探しガイド (Tax Accountant Search Guide), IDEMAE, and a YouTube channel.

At the technology layer, SoVa holds Japanese patent No. 7171976 (granted July 12, 2022) for a chat-based system that automatically determines which government procedures and documents are required based on a company's circumstances and converts them into scheduled tasks with deadline notifications. The firm operates a horizontal team structure (Accounting, Labor/HR, CS, Tax) with internal engineering that continuously improves proprietary workflows, supplemented by a SoVa Partners external specialist network in labor, registration, tax advisory, and business design. Headcount is in the 11–50 range, and the company is headquartered in Kanda, Chiyoda-ku, Tokyo, having relocated in January 2025 to support expansion.

SoVa has raised approximately ¥550 million in disclosed funding to date: a ¥40 million seed round from East Ventures and angels (April 2021), a ~¥230 million pre-Series A reported in Nikkei (April 2023), and a ¥280 million Series A led by JAFCO and Boost Capital (August 2024). The company has publicly targeted 15,000 contract companies by 2026, operates within the Kanto region with a contracted Okayama City entrepreneurship support engagement, and was featured in Forbes JAPAN's Impact 100 (March 2025). Revenue is not publicly disclosed.

Direct peers

• Pilot.com: US tech-enabled bookkeeping, accounting, and CFO services firm focused on startups and SMBs, built around software + dedicated specialist teams. Closest international analogue to SoVa's "specialists plus automation" thesis applied to the startup back-office.
• Bench.co: North American outsourced bookkeeping and accounting firm for small businesses that pairs a proprietary platform with a dedicated team of bookkeepers. Functionally similar to SoVa in productizing monthly accounting as a flat-fee subscription for SMBs.
• freee K.K. Japan's leading cloud accounting and payroll SaaS platform for SMBs and freelancers, and now a formal SoVa partner via the "AI BPO Partner" program. Directly comparable as both a competitor for SMB back-office work and a distribution channel for SoVa's managed services layer.
• TOMA Consulting Group: Mid-sized Japanese tax accountant and business consulting firm offering outsourced accounting, tax, and advisory services to SMBs. Direct comparable as a multi-disciplinary Japanese accounting firm pursuing a higher-value service model.
• A-SaaS Inc. Cloud-based accounting platform purpose-built for Japanese tax accountants and their SMB clients. Comparable to SoVa as another technology-first entrant attacking the Japanese accounting services stack from a SaaS-plus-services angle.
• Mikuni & Co. (Mikuni CPA Group): Established Japanese mid-tier CPA and tax advisory firm offering accounting, tax, and consulting services to growing businesses. Comparable as a multi-partner Japanese accounting firm targeting similar mid-market and growth-stage clients.

Broad incumbents

• Yayoi Co., Ltd. Japan's largest accounting software provider with the dominant installed base among small businesses and tax accountants, plus adjacent services such as Misoca invoicing. Represents the legacy on-premise incumbent SoVa is positioning against.
• TKC Corporation: Large Japanese professional services network providing accounting software, tax filing support, and consulting to a national federation of tax accountant firms. Comparable as the dominant established professional-services distribution network in Japanese accounting.
• Money Forward, Inc. Cloud-based business platform spanning accounting, payroll, HR, and expense management for Japanese SMBs. Competes with SoVa on the technology-enabled accounting layer and is referenced in SoVa's own content as an alternative service for clients.
