Key Takeaways
  • • Marc Wallach, partner and portfolio manager at Ruane Cunniff, argued at Sohn Tokyo 2026 that a Japanese back-office software maker can reach a 30% operating margin and trade at a mid-20s earnings multiple with 20% to 25% annual earnings growth.
  • • The company sells cloud-based accounting, payroll, expense, invoicing and HR software to Japanese small and mid-sized businesses, with about 45% of core ARR from mid-sized firms with more than 50 employees (roughly 17,000 customers).
  • • About 43% of core ARR comes from small businesses with two to 50 employees (about 239,000 customers), most acquired through their accounting firms.
  • • Wallach said AI is more likely to help the company than hurt it, and described its roughly 30-product portfolio as a "rare and potent combination" of breadth and depth.
Summary
Ruane Cunniff portfolio manager Marc Wallach presented a bullish case on a Japanese back-office software company at Sohn Tokyo 2026, according to Hedge Fund Alpha. Wallach, a partner who joined Ruane Cunniff in 2012 and helps run its Wishbone and Poplar private partnerships, described the company as "a world-class software asset" that has lost money for years but is about to begin earning at a higher level.

Wallach's thesis rests on margin expansion. He said that if the company reaches a 30% operating margin, its shares would trade at a mid-20s earnings multiple, with 20% to 25% annual earnings growth ahead. He also argued that artificial intelligence is more likely to help the business than harm it.

The company sells cloud-based accounting, payroll, expense, invoicing and HR software to Japanese companies. According to the article, about 45% of core annual recurring revenue comes from mid-sized businesses with more than 50 employees, across roughly 17,000 customers mostly acquired directly. Another 43% comes from small businesses with two to 50 employees, about 239,000 customers, most of whom arrive through their accounting firms. Over roughly 15 years the company has built about 30 products, and Wallach said it offers a best-of-breed product in each category.
